METHOD OF CALIBRATING OPTICAL-ELECTRONIC DEVICE AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC G01M11/02 G03B43/00 H04N17/00 

FIELD: physics.

SUBSTANCE: method of calibrating the optical-electronic device, which is realized by the corresponding device, consists in orienting the optical-electronic device (OED) to align the image of the collimator mark with the center of the OED frame, sequentially projecting the collimator mark at the specified points in the OED frame by rotating and linearly moving the collimator. For each position of the collimator, the angle of its rotation is measured, the coordinates of the mark image in the frame are determined and the systematic errors of the position of the collimator sight axis relative to the X, Y, Z axes. The lens focal length, the coordinates of the main point of the frame and the distortion of the lens at the given points of the frame are calculated. The calibrated OED is turned over and the actions are repeated. The values of the lens focal length, the coordinates of the main frame point and the lens distortion obtained in two positions of the OED are averaged.

EFFECT: improving the calibration accuracy of the optical-electronic device.
