It calculates.Such as, a kind of automatic angularity measuring instrument of glass panel disclosed in Chinese utility model patent ZL201420545839.9, including
Pedestal, high precision laser range finder, twin shaft guide rail and fixed frame for fixing high precision laser range finder and movement, the height
Precision laser rangefinder can be moved under the drive of twin shaft guide rail and be measured the reference distance of nine measurement points, then
The warp value in eight directions of sample to be tested is calculated separately out according to the reference distance of acquisition, although measuring instrument described in the utility model
The product of any size can be measured, but since the reference distance of each point, and laser can only be measured in measurement process one by one
The each measurement result of rangefinder need to be obtained in the case where board stops vibrations, cause time of measuring long, working efficiency is low.Also
A kind of mode is to survey flatness using Structure light method, and this measurement method mainly utilizes optical grating projection, is thrown in glass surface
The certain stripe pattern of shadow acquires the phase image using camera and preserves, and the phase for then changing striped carries out taking figure again, leads to
The phase for crossing variation and the calibration coordinate on standard flat, calculate the Z axis coordinate value each put in glass planar in the visual field,
And then the face type of the glass surface is calculated, but the measurement method leads to accuracy of detection not due to computational methods too complex
Enough height.
