What is Imaging Software?
An imaging system is a collective name for various types of remote sensor systems that acquire non-photographic remote sensing images of ground objects. Scanning is usually used for imaging, tape recording or indirect recording on film.

- Due to the use of dynamic scanning imaging, the geometric relationship of the image and its correction are more complicated.

High-resolution imaging system
- High-resolution images have two meanings for observation. One is that at the same spatial resolution (when the size of the space corresponding to each pixel is the same), high-resolution images mean that you can see a wider visual field.
- Another significance is that high resolution can provide more details in the same field of view. Both CCD and CMOS chips are moving towards high resolution. One way to improve the resolution is to increase the chip size of the chip, and the second is to reduce the size of the pixel to obtain more image pixels on the same area of the chip.
- At present, the pixel size of cameras can be from 20 m to 2.8 m. Sony claims that 1.2 m chips will be introduced soon, mainly concentrated between 9 m and 4 m. However, the trend of increasing camera resolution by reducing the pixel size is not unlimited. Because the smaller the pixel size, the higher the requirements for optical lenses, and the more complicated the chip production process, the higher the production cost. The trend will surely slow down.
High-speed imaging system
- Speed is another important requirement of CCD cameras. CCD industrial cameras are mainly used in conjunction with assembly guidance and quality inspection of industrial product lines. With the continuous improvement of modern production efficiency, the imaging speed of CCD cameras and the processing speed in the machine are both Increasingly demanding.
- In special high-speed fault diagnosis, motion analysis and process monitoring, the camera is required to reach a frame rate of 500-2000fps. With the continuous development of CMOS technology, through the [2] ROI window setting, 7500fps images can now be easily found. And in ordinary industrial applications, 100-200fps cameras are no longer difficult to find products.
High image quality of imaging system
- High image quality has always been the goal pursued by imaging chips. Although CCDs had inherent advantages in image quality before, with the development of CMOS technology, it has become possible to improve high image quality CMOS chips. At present, CMOS lithography technology can reach 0.25m and 0.18m. Microlens technology has been widely used. Using 4T, 5T and MultiT technology, CMOS chips have made many major breakthroughs in noise resistance and improved sensitivity.
