Trolley bus line catcher automatic positioning system and method based on laser radar

Abstract

The invention provides a trolley bus line catcher automatic positioning system and method based on a laser radar. The system comprises a data acquisition platform and a data analysis platform, which are in wired or wireless connection. The method comprises the following steps: the data acquisition platform carries out acquisition and transmits original data of a single-line laser radar to the data analysis platform; the data analysis platform converts the original data of the single-line laser radar into point cloud data, extracts contour of a line catcher, calculates distance and angle between the line catcher and the single-line laser radar and carries out analysis to obtain distance and angle needing to be adjusted of a trolley bus; the information above is stored and sent to the outside world, and the outside world helps to guide wires of the trolley bus to be connected to the line catcher by utilizing the information above; and the steps above are repeated to realize real-time data update, and thus the overall process of automatic positioning of the trolley bus is realized. The system can obtain environment information through the single-line laser radar, is higher in adaptability, can be adapted to more weather conditions and is lower in cost.

Description

technical field [0001] The invention relates to the technical field of trolleybus positioning, in particular to a laser radar-based automatic positioning system and method for a trolleybus line catcher. Background technique [0002] Trolleybus is an important means of public transportation, but limited by its battery life, trolleybus may need to be charged during driving. At present, the common trolleybuses are mostly charged manually, that is, on the designated line, the driver presses the switch after hearing the corresponding sign, and the dual-source wire automatically rises and enters the catcher, which can be connected by itself. However, when the trolleybus needs to avoid pedestrians or obstacles and cannot accurately stop at the specified position, it is necessary to manually adjust the dual-source wires to connect to the catcher for charging, which is very troublesome and time-consuming. Therefore, it is very necessary to develop an automatic positioning system and...
