The present invention provides an image analysis method for damage gear collision / deformation process, which comprises the following steps: a strain gauge on the tooth root was measured in the mechanical gear; gear is arranged on the front of the shot hole, and the hole shot behind the position signal can be received with laser beam tube; in the measured dynamic mechanical gear working condition, the synchronous acquisition of strain gauge after impact deformation signal and laser on the laser signal shooting tube, real-time monitoring of the deformation signal and the laser signal and the synchronous trigger control by the control processor, high speed camera real-time camera; image based on high speed camera uptake analysis of gear damage, collision / deformation cases. The present invention through external synchronous sampling trigger control system of high speed camera, can timely record the dynamic process of mechanical gear deformation work, through direct observation of each frame image is recorded in the dynamic analysis can clearly and intuitively get gear collision / deformation damage process, higher reliability. The invention also provides a system for realizing the method, which has the advantages of simple structure, low cost, controllable operation, etc..
