Embodiment 1
[0055] The present invention proposes a real-time data fusion mobile robot grid map creation method, the system schematic diagram is as follows figure 1 shown. The neural network is used to fuse the uncertainty of sonar data explained by probability theory and fuzzy logic, and the influence of the spatial correlation of multiple sonars on the state of the same grid is considered to establish an environmental grid map.
[0056] figure 1 Among them, S0, S1, ..., S7 are the ranging values of the sonar sensors installed on the front end of the mobile robot, and O emp {x, y}, O occ {x, y}, O uce {x, y} are the currently calculated grid idle probability, obstacle probability and uncertain state probability, respectively.
[0057] The mobile robot uses ultrasonic ranging sensors to complete environment modeling, and eight sonar ranging sensors are installed on its front end. figure 2 The positions of the sonar sensors of the mobile robot are: ±10°, ±30°, ±50° and ±90°, which ...
