Abstract

In the field of unmanned transportation, the parking position of AGV trolley is not accurate enough when docking at the workstation.This paper uses lidar and depth camera sensors, and through the corresponding coordinate transformation, measures the distance of obstacles and obtains the sensor.Through the selection of the appropriate transfer function and learning algorithm, the RBF neural network is used for training, and the simulation verification results show that the range error of the result obtained by this method is less than 0.1%, and the speed is compared with the traditional BP algorithm.It is increased by 24%, which can be used to assist the relocation of the AGV trolley when it is parked.At the same time, the data obtained through fusion also has certain advantages in future mapping.

Key words
