300,000 pixel industrial camera performance parameters and features

1.Resolution: The number of pixels (pixels) of each image collected by the camera, for the digital camera is generally directly corresponding to the number of pixels of the photoelectric sensor, for the analog camera it depends on the ** system, the PAL system is 768 * 576, and the NTSC system is 640 * 480.

2.Pixel depth: that is, the number of bits of data per pixel, generally 8bit, for digital cameras, there are generally 10bit, 12bit, etc.

3.Frame Rate Line Rate: The rate at which the camera captures transmitted images, generally frames per second for area cameras, for line scan cameras, the number of lines acquired per second (Hz).

Built-in rich IO interfaces to support complex on-site requirements. Integrate multiple groups of controllable light sources to realize independent control of light source splitting and respond to your flexible production needs.

Industrial cameras are a key component of machine vision systems, and their most essential function is to convert optical signals into orderly electrical signals. Choosing the right camera is also an important part of the machine vision system design, which not only directly determines the resolution and quality of the captured images, but also directly relates to the operation mode of the entire system.

Take Teledyne Dalsa's Genie Nano M640 as an example:

The Genie Nano M640 is a Teledyne Dalsa industrial camera with a Python 300 monochrome sensor from On-Semi. Teledyne Dalsa's unique Burst Acquisition technology and TurboDriver capabilities enable acquisition rates of up to 720 FPS at VGA resolution with premium image quality. All Genie cameras are supported by Teledyne Dalsa Sapera software.

Feature highlight: Outstanding price/performance ratio.

Intelligent Mobility & Transportation, Logistics.

Health & Life Sciences, Sport & Exercise.

Surveillance & Security, Defense.

Agricultural applications. Let's filter and see.

The number of pixels in each image acquired by the industrial camera generally corresponds to the number of pixels arranged in the field of the photoelectric sensor: (the resolution of the area scan camera is 795x596024x1024, 2048x2048, 5320x5320, etc.).

First, consider the accuracy of the object to be observed or measured, and choose the resolution according to the accuracy. Camera pixel accuracy = unidirectional field of view, size of camera, unidirectional resolution. Then the unidirectional resolution of the camera = the size of the fan song late mode circumference in the unilateral denier direction of the field of view, and the theoretical accuracy.

information.

Resolution: refers to the pixel distribution on the phase-sensitive surface of the camera's area array sensor, which directly affects the clarity of the shooting.

Frame rate: refers to the number of photos taken by the camera in 1 second, and when shooting high-speed moving objects, the frame rate has a great impact on the shooting effect.

Sensor model: mainly CCD and CMOS, both of which have their own advantages and disadvantages, but CMOS will be the mainstream of the market.

Pixel size: The size of a single pixel, the larger the pixel size, the higher the sensitivity of the camera.

Camera interface: There are many kinds of interfaces for industrial cameras, and the most commonly used ones are cameralink, coaxpress, etc. Among them, CoaxPress is superior to other interfaces in terms of data transfer speed.

Summary of the main parameters of industrial cameras, refer to:

If you are referring to the pixels of an industrial camera, you have to take into account its use scenario.

Generally, the industrial camera (more like a camera) is a long-term working equipment used for 24-hour monitoring of production, R&D, construction sites, traffic and other environments, so its users may be more concerned about its durability, heat, and electronic noise.

Therefore, the pixel of an industrial camera is generally low, because more often it is actually a video recording device rather than a static shooting device (or understood as a static camera device that needs to shoot continuously at a very high speed), and it may be able to shoot hundreds of shots a second** (if it is an industrial camera for transportation, it must collect vehicle violation data through fast continuous shooting), so the camera is required to have a high speed. In addition, in some environments, industrial cameras must also have night vision capabilities, waterproof, etc.

But as far as a single static ** is concerned, the image quality of an industrial camera is actually no different from that of an ordinary mobile phone, because its CMOS sensor area is comparable to that of a mobile phone, so its static image quality is not the main thing.

TEO Dior Technology represents the selection parameters of 3 million industrial cameras.

1. Lens mount and maximum CCD size.

As long as the lens interface can be matched with the camera interface, it can be matched and installed through the external conversion port, and the lens can support the largest CCD size, and should be greater than or equal to the size of the optional camera CCD chip.

Second, the focal length of the lens.

Once you know the camera CCD size, working distance, and field of view, you can calculate the focal length of the lens you need.

3. Lens aperture.

The brightness of the image is usually determined by the size of the lens aperture, if it is used in a relatively short environment, or when shooting high-speed moving objects, you should choose a large aperture lens, which can improve the brightness of the image.

At present, the file is generally 10 million pixels, but 3 million effective pixels for individuals is enough, and a very small number of photographers and reporters must use high pixels, and individuals spend more money.

Fashion choice Sony, photography choice Nikon, Canon, Sony video camera is very good, the camera is average, low cost performance. The card machine is more than 1500 is luxurious, less than 5 times the light change is low-end, and the periscope lens has poor imaging.

1. Canon A2000 pixel 10 million sense Souyou next to the world oak optical element 1 inch light change 6 times f= equivalent to 35mm focal length 36-216mm 1,004.

2. Nikon S560 pixel 10 million image sensor 1 inch CCD light change 5 times F = equivalent to 35mm focal length 1,004.

3. Sony W150 pixel 8.1 million image sensor 1 inch optical zoom: 5x f=5-25mm, equivalent to 35mm, focal length 30-150mm

The A2000 and S560 are indistinguishable, each with its own strengths, and is the best among card players.

Cameras rarely use interpolated pixels, and there is no effective number of pixels that is the number of pixels of a digital camera. That's right, except for miscellaneous machines, such as Taiwanese brands.

Now the bottom products on the market are also more than 8.2 million pixels, and you can buy a camera with more than 8.2 million pixels for 1,000 yuan!

It's 300w pixels. No matter what electronics are. Needless to say, how many pixels are equivalent to a camera.
