Abstract

The invention belongs to the field of mobile positioning of intelligent robots, and particularly relates to a device for positioning the running track of a mobile robot and a method for positioning the running track of the mobile robot. The device for positioning the running track of the mobile robot comprises a central processing unit, a gyro for measuring the rotation angle of the robot, and a sensor for measuring the displacements in the horizontal and vertical directions, wherein transmission ports of the gyro and the sensor are connected with a transmission port of the central processing unit respectively; the sensor employs an optical sensing device or a photoelectric encoding device; the optical sensing device comprises an optical imaging engine and mainly comprises a complementary metal oxide semiconductor (CMOS) image sensor and an optical positioning digital signal processor (DSP) module; and the optical positioning DSP module is in charge of analysis and comparison of adjacent image matrixes so as to compute the horizontal and vertical moving distances of the robot within a unit time. By the method and the device, the moving track of the robot can be precisely positioned without the help of external equipment.

Description

technical field [0001] The invention belongs to the technical field of mobile positioning of intelligent robots, and in particular relates to a moving track positioning device of a mobile robot and a positioning method thereof. Background technique [0002] At present, more and more mobile robots are applied in production and life, and in many robot competitions, it is necessary to realize the accurate positioning of the position information of mobile robots. At present, the mature positioning methods of mobile robots include magnetic positioning, ultrasonic positioning, GPS positioning, etc., but they all need the help of external positioning equipment, and it is difficult to rely on their own equipment to achieve their own trajectory positioning. Contents of the invention [0003] The invention aims to overcome the disadvantages of the prior art and provide a mobile robot track positioning device which can realize the positioning of the moving track by its own device wit...
