The specific embodiment
The utility model as shown in Figure 1, the utility model is divided into vision system 1 and robot system 2 two parts plates and forms, and the data communication facility, the robot that finish between the calibrating function, feature extraction functions, test result analysis function, two systems of video camera and robot finish the corresponding sports function according to the vision system feedback.
The utility model is that vision system 1 is connected to robot system 2; Wherein vision system 1 is connected to two industrial cameras 5 simultaneously for the image pick-up card 3 of industrial computer 13, the VPU 4 of industrial computer 13 is connected to the robot electric-control system 6 of robot system 2, the servo motor 10 of the servo-driver 8 control robot bodies of robot electric-control system 5, thereby by servo motor 10 motions of 3D rendering collection control robot body 9, finish a series of action.
The robot controller 7 of robot electric-control system 6 is connected with the VPU 4 of industrial computer 13.
Detailed process of the present utility model is 3D vision system industrial robot operation process chart as shown in Figure 2.
The utility model adopts six degree of freedom tandem type industrial robot, needs robot to have higher absolute positional accuracy, requires in positive and negative 1mm.Therefore must demarcate robot, comprise that each axostylus axostyle is long, each zero point, the high capacity robot also needs the distortion of gravity and mechanical arm is compensated, and makes robot have higher absolute positional accuracy under rectangular coordinate system.Concrete scaling method is finished by laser tracker.Vision system 1 is that two industrial cameras 5 are installed in robot end's flange, distance between two industrial cameras 5 is relevant with the focal length of camera lens, distance is the bigger the better in theory, but consider that lens focus and pattern distortion require in a scope, but at least greater than 1/5 of focal length, guarantee the field range that two industrial cameras 5 can photograph product simultaneously and may move at random simultaneously.It is to make two cameras take a scaling board (scaling board is to be covered with obviously alternate flat board of the foursquare black and white edge feature of 20*20) that absolute precision is higher simultaneously that vision system is demarcated, take pictures in opposite directions by 9 or 9 above diverse locations from scaling board for industrial camera 5, according to the position under the robot rectangular coordinate system, 3d space under the match camera coordinates system, and feed back 2D and 3D error respectively to the user.The user judges whether calibration result is qualified.Characteristics of image is mentioned need adopt product feature religion obvious characteristics or edge contour as far as possible, and a product can extract a plurality of characteristic points to be judged simultaneously, can arrange one or two characteristic point of flicker allow to mention less than, improve the product identification rate.3D information and the robot rectangular coordinate system of product should be consistent, and are generally X, Y, Z, A, B, C.Wherein XYZ is the position under the product center point rectangular coordinate system, and ABC is the attitude of product center point, should keep ABC consistent with the gesticulate of robot, is generally XYZ, Eulerian angles and hypercomplex number expression waies such as ZYZ.
