Mechanism Design And Experimental Study Of Binocular Stereo Vision Platform

Machine vision is an active and challenging research field, its research and application areas spread widely. Machine vision technology is a rising integrative science technology, which is the last word referring electronics, mechanism, optics, computer and communication technology, and which is the most important part of high tech field. With the target of binocular stereo vision Mechanism research,, this paper discusses binocular stereo vision system, level adjustment plan , level adjustment mechanism and camera calibration experiment. The overall scheme of binocular stereo vision system had been determined by the comprehensive analysis and research, which makes the camera control mechanism, the target control mechanism , the guide rail mechanism and the control system a complete systems. Then , the design proposal of the camera control mechanism, the target control mechanism and the guide rail mechanism had been narrated separately, moreover, in view of the level adjustment request ,the two kind of plans using the inclination angle sensor adjustment and the imagery processing adjustment had been determined, and the advantage and disadvantage of the two kinds had been analyzed in detail.Based on the level adjustment plan, level control mechanism had been analyzed and computed, thus the level control mechanism based on the elastic part had been determined and constitution and the principle of work of the mechanism had been narrated. Moreover, the precise computation had been separately carried on through the manual computing mode and the software computing mode to the level control element, as see from the computation result, the finite element analysis surpasses the manual computation obviously by the high precision, the quick computation speed and the easy operation.Based on the prototype, the adjusting level experiment based on the imagery processing had been done, namely carrying on the filter, the threshold value division and the edge detection through the SWIFT algorithm to the gathering image, and obtaining the long minor axis, the central coordinates and the major axis with X axis included angle of the ellipse. The process of adjustment target surface and the camera surface parallel process is using firstly the horizontal accommodometer to adjust approximately the target and the horizontal plane vertical, then using imagery processing method separately to adjust left camera image plane and right camera image plane with target surface parallel. In the entire adjustment process, the entire wrap organization can easy movement, convenient adjustment, easy operation, and the camera demarcation experiment based on the target surface adjustment with two camera image plane parallel had been carried on, as see from the demarcation situation, the demarcation process becomes extremely simple.
