The real-time measurement of deformation of the photoelectric theodolite’svehicle p latform is done through high precision and non-touch system in this paper. The video judging technology is adop ted to incep tand dispose CCD video signal, and the video is disposed and collected through the method of simultaneity. As a result, the values of undershoot of vehicle platform is obtained, and the values of its deformation is calculated. This is a great foundation formore research in theory and practice.
