New stereo shooting evaluation metric based on stereoscopic distortion and subjective perception

In this paper, we examined the stereoscopic distortion by varying image acquisition parameters including but not limited to inter-camera distance, camera focal length, and shooting distance. Since a lot of new elements or problems about stereoscopic perception have not been considered or precisely defined before, an advanced shooting principle is raised in this paper to guarantee the overall quality of stereoscopic images. In this paper, based on stereoscopic distortion and features of camera configurations, we present new shooting formulae for both toed-in and parallel camera configurations. Besides, a new shooting evaluation metric is proposed for the evaluation of stereo camera quality. The experimental results show that the proposed approach can precisely assess the visual perception quality of stereo images according to the shooting parameters and can effectively evaluate the quality of stereo camera.
