Robot visual servo control system based on images

The invention discloses a robot visual servo control system based on images. The robot visual servo control system comprises a sample to be tested, a robot executing mechanism, a robot control center, a camera acquisition device and an image control device, wherein the robot executing mechanism comprises motion mechanisms which drive the sample to be tested to make linear motion in a two-dimensional space, and servo driving mechanisms which drive the motion mechanisms to perform operation; the camera acquisition device comprises an image acquisition module and an image-characteristic extracting module connected with the image acquisition module, the image-characteristic extracting module is connected with the image control device, the image-characteristic extracting module transmits the information of the acquired current image position A and the information of the expected image position B to the image control device, the information is transmitted to the robot control center through the image control device, and a first servo driving mechanism and a second servo driving mechanism are controlled by the robot control center so as to respectively drive a first motion mechanism and a second motion mechanism. The visual servo control system is simple in structure and high in control precision, and the responding speed of the system is increased.
