[0054] The applicant also found that there is a variety of non-contact plate-shaped scanning equipment based on laser profile measurement techniques, and the algorithms used in the market are difficult, and the measurement range is small, no shock absorber Measures, no evaluation solutions. E.g:
[0055] A multi-line laser contour scanning sensor global calibration method is based on a calibration method of a three-dimensional target. It needs to be calibrated in advance before each measurement, and the target is required to ensure that the wire laser transmitted by each sensor is intercepted. Features, it is difficult to use the production site of the working condition environment.
[0056]Based on a single plate shape detection camera system of the laser line, the system is based on a line laser detection plate shape offline, the system using a line laser emitters emitting laser plate items, recorded by the camera to take plate video scanning process, the final process by the da...
