In order to realize the automatic trajectory control of the mobile logistics robot,this paper studies the mobile logistics robot control system based on image recognition results using the probabilistic neural network. In this paper,we design the image acquisition and recognition processing module based on the probabilistic neural network and studies the key problems of the modeling and control of the autonomous motion of the mobile logistics robot. By setting up the image acquisition and recognition processing module based on probabilistic neural network and the mathematical model of the trajectory control of the mobile logistics robot,a path control algorithm based on the image recognition results of this kind of mobile robot is designed. The Robotic tool toolbox of simulation software MATLAB is used to simulate the control trajectory of mobile robot. The simulation results show that the path control scheme in this paper can make the mobile robot achieve the desired path tracking successfully according to the image recognition results. Under the condition of 0. 4 salt and pepper noise,the correct rate of path control is 98%,and the theoretical basis and application foundation are provided for the realization of autonomous control of the trajectory of mobile robot based on vision under noise environment.
