Quality evaluating device of stereo projection apparatus

The utility model is suitable for the stereo projection display technology field, and provides a quality evaluating device of a stereo projection apparatus. The device includes a signal receiving module which receives an evaluating item selective signal input by a user, an image acquiring module which acquires a corresponding projection image of the projection apparatus on a projection screen based on the evaluating item selective signal which is received by the signal receiving module, a calculating module which calculates a corresponding measuring value of an evaluating item based on the image acquired by the image acquiring module, a comparing module which compares the measuring value calculated by the calculating module with a pre-existing maximum deviation value, and a display module which displays a comparison result of the comparing module. According to different evaluating items, the quality evaluating device acquires and processes multiple frames of projection images in a real-time and time-sharing m
