Abstract

In order to solve the problem of measuring the size of the truck carriage and positioning the vehicle, a lidar-based non-contact dimensional measurement device for truck carriage is designed. The measuring device is composed of a vertical two-dimensional laser radar, a four-degree-of-freedom manipulator, a sliding rail and an industrial computer. The point cloud information of the length and width of the carriage is obtained by the laser radar. The linear features are extracted by the probabilistic Hough transform algorithm, and then the outline segments of the carriage are extracted according to the prior knowledge, so as to measure the length, width and height of the carriage and position the vehicle. The measurement result of the carriage model shows that the device is characterized by small measurement error, high measurement efficiency and simple structure and so on.
