Computer vision system composition:
1. Image acquisition system
2. Image processing system
3. Information comprehensive processing and analysis system
Typical applications :
1. Size measurement
2. Positioning guidance
3. Information identification
4. Defect detection
Line scan camera features:
1. The frequency of taking pictures is fast (the exposure time is short and a light source is required)
2. Dynamic scenes (speed matching, external trigger required)
3. Large amount of data (high bandwidth requirements, acquisition card required)
4. Wide horizontal field of view (high lens requirements, requiring a large target lens)
5. Installation direction (there is no need to configure the movement direction for black and white, and vice versa for color, otherwise jagged phenomena will occur)
Line scan camera parameters:
1. Line frequency (that is, the frequency of taking pictures, the line frequency can be set freely in free mode, and it is related to the incoming line model in trigger mode)
2. Line height (the number of lines required to form an image frame)
3. Scanning direction (selection of horizontal scanning direction)
4. Departure selection (frame trigger [even speed], line trigger, for different scenarios)
5. Trigger source under row trigger
6. Encoder control
7. Frequency converter control
8. Frame Timeout frame waiting time (if the frame is not full, the image will be discarded, otherwise the black will be filled automatically)
9. Binning (black and white)
PS: speed-v, lateral field of view-L, current lateral resolution-W; commonly used formula line frequency F = (WX v)/L
