摘　　要：获取立体视觉信息是人们感知世界的基本能力之一,其中运动立体视觉信息的获取不仅是生物视觉系统在动态世界中生存的关键能力,也是人工视觉系统高效处理立体视频的重要手段。为了设计出贴合人眼视觉特性的3D深度运动感知模型,需要明确挖掘人类对立体运动感知的显著特征后再设计主观实验。文中根据单目和双目线索设计了立体运动视觉刺激视频,并采用控制变量的方法,分别探究了目标球体运动速度、参考球体旋转半径及被试正确感知的相互关系,并分析了目标运动方向与被试感知方向之间的关系。首先对实验条件进行探究,结果发现目标与参考的相对距离越小拦截成功率越高,该结果表明目标同参考之间的相对位置关系会影响被试的感知正确性。其次,采用了拦截成功百分比和感知偏差两个行为测量标准对被试感知能力进行分析,结果发现相比横向运动,深度运动正确感知的成功率超出约42.67%~47.01%。这表明不同运动方位的感知不对称,且深度运动带来的视觉刺激更明显。该研究探索了人类对运动感知的显著特征,并为后续设计3D运动感知模型提供了一种新的判断模型感知效果的主观对比标准,使原有立体感知能力的指标更加细化。Obtaining stereoscopic information is one of the basic abilities of human beings to perceive the world.Through stereo vision, we can judge the shape, size, distance, relative position of objects, as well as the direction and speed of changes in object motion information.Among them, the perception information of moving objects plays an important role in stereo vision perception.The acquisition of motion visual information is not only the key ability of biological vision systems to survive in a dynamic world, but also an important means for artificial vision systems to efficiently process stereoscopic video.Therefore, in order to design a 3 D depth motion perception model that conforms to the visual characteristics of human eyes, it is necessary to explicitly excavate the salient features of human perception of stereoscopic motion, so as to design experiments to explore.In this paper, motion stereo videos are designed as visual stimuli based on monocular and binocular cues, and subjective experiments are designed using the control variable method.The experiment explores two parts: the influence of the relative distance between the target and the reference sphere on the subjects’ perception ability, and the relationship between the actual movement direction of the target and the subjects’ perception direction.Experimental data is analyzed by using two behavioral measures: the percentage of successfully intercepted targets and the perceived bias.The conclusion shows that, firstly, the smaller the relative distance between the target and the reference, the higher the interception success rate.The target velocity and the reference’s motion radius affect the relative distance of the target and reference spheres.This indicates that the relative positional relationship between the target and the reference plays an important role in the human eye’s perception of moving objects.Motion perception has a certain relativity, and motion is easier to perceive at the position with reference point and the position close to
