Usually, the area scan camera is expressed by the frame rate, and the unit is fps (Frame Per second), such as 30fps, which means that the camera can capture up to 30 frames of images within 1 second; line scan Cameras usually use the line frequency as the unit KHz.
Current CMOS image sensors also suffer from fixed image noise, which is caused by the inherent structure of the sensor. Each pixel or column of pixels has its own amplifier, and small mismatches in the amplifiers change the gain and bias associated with it.
Because the laser has the advantages of high directivity, high monochromaticity and high power, these are very critical for measuring long distances, determining target orientation, improving the signal-to-noise ratio of the receiving system, and ensuring measurement accuracy,
Laser displacement sensor is an instrument that uses laser to accurately measure the distance of the target. The laser ranging sensor emits a very thin laser beam to the target during operation, and the photoelectric element receives the laser beam reflected by the target.
The 3D line laser profile sensor adopts the principle of laser triangulation. First, a laser beam is used to irradiate the surface of the object to be measured, and the reflected light forms a spot on the surface of the photosensitive element through the optical lens group.
The measurement process of the laser 3D displacement sensor requires a complete triangular optical path, and whether a complete triangular optical path can be formed during the measurement process determines whether it can bring accurate data results.
The visual inspection system brings convenience to industrial production and people's life. The visual inspection system converts the inspection object into an image using a scanning device, a photographing device, or the like, and outputs the image to an image device.
Application areas include aerospace, university research institutes, ships, sports, automotive industry, automated production lines, various product testing, mining, ceramics, pharmaceuticals, coatings, papermaking, water treatment and drilling mud and other fields.
In the process of practical application of 3D scanners, the application of reverse process is a brand-new technical process, which can conduct comprehensive analysis and research on all targets, and can obtain the processing process of the entire product through relevant reasons.
According to the type of target surface, it can be divided into area scan cameras and line scan cameras: area scan cameras refer to industrial cameras that can acquire images at one time, and are widely used in shape, size, position and other detection applications.
