Digital reconstruction technology of corridor environment based on single line lidar

Aiming at the problem of digital reconstruction of corridor environment, a digital reconstruction system based on single line lidar was designed. In this system, a mobile robot mounted with single line lidar sensor was used to build a three-dimensional radar scanning system to realize automatic scanning and real-time reconstruction of corridor environment. In this paper, first the hardware of the system was built, and then the digital reconstruction process of the system was introduced in detail, including the design of mobile robot control module, coordinate conversion, data fusion, etc. A fuzzy PID control algorithm was added to the control system to solve the problem of mobile robot motion deviation and ensure the accuracy of system data acquisition. For the conversion of 2D point cloud to 3D point cloud, a method of fusion of odometer data and lidar sensor data was proposed. Finally, the experimental test was carried out. The automatic acquisition and real-time reconstruction of general complex corridor scenes can be realized by this system, which not only has high accuracy, but also has obvious reconstruction characteristics.
