Depth Perception In Cue Conflict And The Mechanism Of Formation

Depth perception is an important topic in the field of the human and computer vision research. There are two main categories of cues in the course of stereo vision formation: One is monocular cue, it is the characteristics which can cause depth perception but not need interocular processing. Another is binocular disparity which is due to the slightly horizontal position of eyes and causing two different image of the retina. It is the physical that need interocular processing.Since the 1960s when Julesz found that as long as the disparity can create a depth perception by RDS, most of the researchers are concerned about the relation of binocular disparity to depth perception, and ignored the impact of monocular. In fact, both monocular and binocular cues play a very important role in the process of the depth perception formation. For example, a picture which includes monocular cues such as overlap, texture gradient, lines perspective, movement parallax and so on, have great impact to depth perception and a wide range of applications in virtual reality and computer vision research. But so far the intercations between the two still do not have been seriously attention.In order to make these problems solved, this paper design a series of psychological physics experiment which include conflicts of monocular and binocular cues, and study the impact of the two by the method of disturbance analysis. In the last, summed up each cue weight of the impact qualitatively, and obtain the new understanding about the cues conflict to the depth perception. The main content are as following:1 Analyzing two cues which cause the depth perception, this paper elaborate the characteristics and differences of the depth perception from two cues.2 It proves that there is interaction between the two cues and impact on the depth perception by the experiments of cues conflict.3 It obtains the law which has impact of depth perception qualitatively by changing the composition of monocular and binocular respectively.4 This law explained some of the current experiments which can not be explained by the last experiments. These studies and the results show that the human depth perception is affected by both monocular and binocular cues at the same time. Therefore, it must consider their role in the performance of virtual reality and computer vision to get the best visual effects.
