Discuss which one is better about the hundreds of thousands of laser 3D number readers?

Now we use optical scanners, the accuracy is higher, our Sentu company is using atos, the effect of copying, customers are more satisfied.

How is Minolta?

**More than 400,000, the size can be done from 10cm*10cm to 1m*1m or more, the accuracy is better than that of the ATOS I generation, but the speed is very fast, a scan takes 1 second. View the original post

There are not many domestic independent research and development enterprises of 3D scanners, Xintuo 3D is one of our direct contact, the product quality is excellent, the service outlets are many, and it is more timely.

The 3D laser scanner, also known as the laser scanner, works by scanning technology to measure the size and shape of the workpiece. The laser scanner uses a rotating motor with good stability and accuracy, and when the beam hits (emits) the multi-faceted prism driven by the motor, it reflects and forms a scanning beam. Because the faceted prism gauge is located on the front focal plane of the scanning lens, and rotates uniformly, the incident angle of the laser beam to the mirror is relatively continuous, so the reflection angle is also continuously changed, and a parallel and continuous top-down scanning line is formed through the action of the scanning lens.

l=v*△t

where l: the working size (length) to be measured

v : Linear velocity of the scan.

t: The time the beam is blocked.

The scanning method is based on time, also known as the time method. It is a very accurate, fast and simple operation instrument, which can be installed in production and form an instrument for inspection while producing. The basic structure of the laser scanner includes the laser light source and scanner, the light sensor (detector), the control unit and other parts.

The laser light source is a closed type, which is less susceptible to the influence of the environment, and is easy to form a beam, often using low-power visible light lasers, such as helium-neon lasers, semiconductor lasers, etc., and the scanner is a rotating multi-faceted prism gauge or double-sided mirror, when the beam enters the scanner, it rotates quickly to reflect the laser light into a scanning beam. During the entire beam scanning process, the light is blocked if there is a workpiece, so the diameter can be measured. Before measuring, it must be calibrated with two gauges of known size, and then if all the measuring dimensions are between these two gauges, the size to be measured can be obtained after electronic signal processing.

Therefore, it is also called a laser gauge.

Laser scanners are used for many purposes, such as diameter, position, edge, and offset. (a) Measurement of the outer diameter of the tube; (b) Measurement of the clearance between the two rollers; (c) Measurement of the height of the bottle contents; (d) Control of sheet metal edges; (e) Simultaneous measurement of the X and Y axes of the tube; (f) Line of production** measurement (left and right movement by scanner); g) Automatic inspection of the outer diameter; (h) Measure the diameter of two workpieces at the same time.

The laser scanner is used in the industrial production of ** inspection products, using this non-contact without downtime, with automatic alarm and feedback control and other functions. The measuring range is between mm and 457 mm, and the accuracy can be up to m.

The three-dimensional laser scanning machine, also known as the three-dimensional laser scanner, is a scientific instrument, which works by virtue of the scanning technology to measure the size and shape of the workpiece. It can detect and analyze the shape (geometry) and appearance data (e.g., color, surface albedo, etc.) of real-world objects or environments. It adopts a rotating motor with good stability and accuracy, when the beam hits (emits) the multi-faceted prism driven by the motor and reflects to form a scanning beam, because the multi-faceted prism is located on the front focal plane of the scanning lens, and the uniform rotation makes the laser beam change relatively continuously for the mirror, so the reflection angle also changes continuously, and forms a parallel and continuous top-down scanning line through the action of the scanning lens.

The 3D laser number reader is used in reverse engineering design, complex surface reading, and 3D measurement of workpieces. For the existing 3D physical objects (samples or models) without technical documents, the contour geometry data of the object can be quickly measured, and the surface digital model of the general output format can be constructed and modified.

Features of 3D laser number reader:

The micron optical electronic ruler is used for measurement and positioning, and the movement is fully closed-loop.

2. The positioning accuracy of the number reader is very high.

3. Double-line laser scanning, fast speed, 2000-10000 points per second.

4. Double CCD points to eliminate the dead angle of scanning.

5. Open scanning design, which can scan large objects.

6. Distribution rotary table, which can realize three-dimensional and all-round scanning of workpieces.

I think laser TV.

It is not recommended for the following reasons.

First of all,At this stage, laser TV is in the experimental stage,And a little clearer**Generally more than 5,000 yuan,The R&D cost that users need to share is too high,And at present,Only about 3,000 yuan**You can buy a clearer than laser TVLEDOROLEDThe screen is self-luminous,So according to the price,Laser TV is a little inappropriate。

Moreover, the life span of laser TVs is generally relatively small, and the problem of discoloration of the bulb will generally occur in about five years. In principle, it is driven by light bulbs, but the projection lamp is generally turned on for a small time, and it may be used for several hours or even half a day each time, which will accelerate the aging of the TV. Although the brightness is relatively high, it will turn yellow after a long time.

Finally, most of the current laser TVs are relatively small in size, and the sound is not very satisfactory. Although this product has stereo sound, because of its small size, the sound power is also small, and it cannot be fully covered for some large bedrooms.

Laser TV is worth buying,Let's take a look at the advantages and disadvantages of laser TV。

Advantage 1:The color of laser TV is more vivid,And the brightness is also relatively high,The requirements for the screen material are not high,Not only flat,Curved surfaces can also be,And it can make the user's eyes more comfortable。 And it doesn't hurt the eyes for a long time**.

Advantage 2: Laser products have a longer service life, can be used continuously for millions of hours, and the quality is better, the technology is more advanced, and it will slowly become a mainstream TV type in the future. In the long run, it is more environmentally friendly and energy-saving.

Advantage 3: Although it is a laser, even if the TV screen is broken, the laser will not cause any harm to the human body, because the laser is treated and harmless to the body. Security is high.

The disadvantage of laser TV series is that the current cost is relatively high, so it cannot be widely produced. The price is also relatively high, not everyone can accept it, and the mention of laser TV is relatively large, if the space at home is too small, it is not suitable to use this TV. The most important thing is that the image quality cannot reach 4K, and users who pursue high-quality image quality may not buy it.

Laser TV is not recommended for everyone to buy,Why? Let's talk about the pros and cons.

Pros: The focus is better, the picture will be larger, even if it is very close to the wall, it will show a large picture with small radiation, and it will not hurt the eyes for a long time, its image acquisition comes from its screen reflection, compared with other models, the damage to the human eye is small, and you will not feel tired even if you are tired for a long time.

It is suitable for the elderly and children, at present, it basically comes with an intelligent system and supports intelligent voice function, the elderly, children will not be so complicated when they are taught, and it is also very practical.

Disadvantages: too expensive, not the average person can afford it, its ** has fallen to less than 10,000 yuan at this stage, but compared with more and more cheap electrical appliances, obviously the latter is more close to the people. For ordinary families, it is still a "luxury".

**There is a limit, that is, if it is daytime or outdoors, its brightness will not be seen clearly, because if it is too bright, it will cover it, and only in dim can there be a good visual effect.

It's not actually a new species, if it's not a particularly rich person, or a particularly high requirement in this area, I don't think it's necessary, as a part of an ordinary family, the daily is enough for the whole family to look up, and now everyone doesn't see it much, it's all playing with mobile phones, why waste money, do you think I'm right?

It's worth buying,Laser TV is a kind of TV that is just emerging now,Compared with general TV,It has obvious advantages,But there are also some inappropriateness。

First of all, let's talk about its advantages:

1. The screen resolution of laser TV is high, so we will feel clearer when we are in **.

2、Laser TV uses laser as the emission source,We only need to use the curtain it needs to be projected,In this process,We can choose different sizes of screens,This gives us great selectivity。

3、The color of laser TV is more vivid than that of ordinary TV,And its brightness is high,Our eyes will be more comfortable when we watch,It will not cause great damage to our eyes like the previous TV。

4. Laser TV can cover 90% of the colors that our human eyes can see, while previous TVs can cover up to 40% of what we see.

5、Laser TV has a sense of realism and layering,It will bring us a sense of presence when the film is a**。 And he also adapts to the standards of all TVs, being able to completely replace any TV on the market today.

6、Laser TV is very suitable for placing in the hall,Just imagine,A family watching a movie in the living room,In this case,Is there a feeling of a small movie café?

And then there's its drawback:

As a new type of TV that has just emerged, laser TV is not yet very mature in technology. At present, there is no way to achieve universal access. It's more expensive, and it's cumbersome to repair.

Summary: There are many advantages of laser TV, and it is far better than our current traditional TV, but it has not yet reached the popularization of civilians. If you can afford it, you can buy it. After all, the ** effect of laser TV is very good, and it is worth starting.

Personally, I think lasers.

The TV is still worth buying.

Let's start by looking at the advantages of laser TV TV.

1. Laser TV has the advantage of a large screen of 100 inches and high cost performance.

100-inch LCD TVs are often hundreds of thousands, which is difficult for ordinary people to afford; And laser TV is born with a giant screen advantage,100Inch**More than 50,000,Compared with the former,Laser TV** is lower。 BenQ laser TVI950L has a 100-inch large screen,**More sense of accomplishment in film and television。

2. Provide a new solution for video wall.

As the visual center of the living room, the TV background wall is really difficult to design. But in fact, you can consider replacing it with a 100-inch large screen of laser TV, keeping the complete wall, simple and beautiful; In addition, the screen does not need to be plugged in, there is no need to hide the wires, and the wall is more neat and refreshing. This is the case with BenQ laser TV i950L, which brings a new aesthetic to the living room.

3. The light of laser TV is soft and eye friendly.

Laser TV is born with the advantage of eye protection,Unlike LCD TVs based on the principle of direct light,Light directly enters the human eye; BenQ laser TVI950L is based on the principle of diffuse reflection,Light is projected to the screen first,And then reflected into the human eye,It can alleviate visual fatigue,More eye protection。

So what are the disadvantages of laser TV?

Overall** is higher.

At present, the price of laser TV is high,People who don't know about it or have a limited budget for home appliance purchase generally don't consider it,Consumer groups are limited。

In general,Laser TV is a new category of TV that has emerged in recent years,Given that it is a new type of TV based on the principle of projection,Projection-related technology is undoubtedly the key to product quality。

I've been to BenQ i950L this laser TV offline before,Here is a recommendation。

As a professional projection manufacturer, BenQ has been deeply cultivated in the field of projection for 20 years, and the technology has been precipitated for a long time. And the color accuracy of their home is the most amazing display effect I have seen among all laser TVs on the market,If you are interested, you can go to the offline physical store to take a look,Compare and compare。

Laser TV is the trend,But the first person to eat crabs is at risk of being poisoned,It is recommended to buy it after maturity,Blind pursuit of the front position,It's ignorant,Irrational,It's also a manifestation of irresponsibility to yourself and your family,It may bring property and loss of life,Please three or four。

At present, there are three main types of car headlights: halogen lamps, xenon headlights, and LED lights, and laser headlights are less introduced here.

The halogen lamp is equivalent to an upgraded version of the incandescent lamp, and the light emitted by the halogen lamp is yellow, which has the advantage of strong penetration, and can still provide the driver with a better vision in rain, snow and foggy weather. However, due to the insufficient brightness of the light bulbs, the dim light makes it difficult for the driver to judge the road well.

Xenon headlights generally refer to the xenon lamp with lenses, the color of the xenon lamp is white, compared with the halogen lamp, the xenon lamp has higher brightness, lower power consumption, longer life, and more stable lighting effect, so the vast majority of models at this stage are using xenon headlights. Xenon lamps also have disadvantages, and their penetration is not as strong as halogen lamps.

Changed the lighting effect of the APA xenon headlights.

LED lights emit light from a cold light source, so they consume less energy and consume less electricity in energy conversion. In addition, LED also has the advantages of brightness, simple structure, and more free shape of the lamp group. The disadvantage is that the heat generation is large, and due to the low brightness of a single LED element, to achieve the brightness level of a xenon lamp, a group of LEDs is necessary, and the cost is higher.
