Embodiment Construction
[0036]The laser beam pose calibration method based on machine vision in large-scale space proposed by the present invention uses the horizontal axis and vertical axis parameters of the high-precision two-dimensional turntable that has been calibrated to drive the high-precision two-dimensional turntable to drive the The laser rotates in space, using the fixed point and direction vector on the horizontal and vertical axes of the two-dimensional turntable as a reference, the direction vector and coordinates of the laser beam and the fixed point on it after rotation are obtained, and finally fitted by least squares Algorithm to calculate the spatial pose of the laser beam.
[0037] The pose calibration system of the laser beam in a large-scale space is mainly composed of a high-precision two-dimensional turntable, a laser to be calibrated, a 5 million industrial camera, a laser tracker, a reflective hollow target ball and a hemispherical target. Among them, the reflective hollow ...
