Described step (1) comprises the steps:
A. television cameras to be debug are fixed on the turntable of rotation centering equipment;
B. directly over television cameras to be debug, set up a parallel light tube, television cameras are aimed at parallel light tube, light is passed through on the parallel light tube focal plane behind the crosshair graticle, enter television cameras and form the crosshair picture;
C. the internal focusing telescope with the turntable below receives the crosshair picture, revolving-turret is adjusted the angle of television cameras, make the crosshair picture picture circle amount in the telescope reach minimum, this moment, the television cameras optical axis was parallel with the parallel light tube emergent ray, fixedly the television cameras angle.
The process of described step (2) is as follows:
At the television cameras that fix angle an adjustable mirror is installed, adjust the angle of adjustable mirror, to look like to draw the circle amount minimum so that reflex to cross-graduation in the parallel light tube through adjustable mirror, i.e. the vertical fixedly regulating reflection mirror angle of reflecting surface of the optical axis of television cameras and adjustable mirror.
Described step (3) comprises the steps:
A. will install to through the television cameras with adjustable mirror of above-mentioned steps adjustment on the television unit debug platform, adjust parallel light tube take the normal of adjustable mirror as benchmark, make adjustable mirror autocollimatic in the parallel light tube of resolution chart;
B. fixedly the television cameras position is motionless, removes the adjustable mirror on it, and take with the parallel light tube of resolution chart as benchmark, adjust the CCD position, make picture the most clear, finish docking of CCD and television cameras.
The invention has the beneficial effects as follows: the present invention at first uses adjustable mirror simulated television camera lens optical axis, when television cameras and CCD parts are debug, adjust parallel light tube take this adjustable mirror as benchmark, and adjust the position of CCD according to the position of this parallel light tube, make picture the most clear.The present invention is applicable to all television cameras, and is practical, can accurately determine the true optical axis of television cameras, and debuging for television unit provides accurately optics basis.
