Compartment laser scanning measuring and positioning method

Abstract

The invention provides a compartment laser scanning measuring and positioning method comprising the steps that a laser distance measuring sensor measures distance of the sensor to a compartment in real time and transmits the measured data to a controller in real time; a position sensor acquires coordinate position information of the laser distance measuring sensor in real time and transmits the coordinate position information to the controller in real time; the controller receives measuring information of the laser distance measuring sensor and judges state information of the measuring information; and the related information (at least including chassis height of the compartment) of the compartment is confirmed according to the state information and the coordinate position information of the laser distance measuring sensor, and coordinate rage information of the compartment in a sampling area is positioned according to the related information of the compartment Light spot diameter of the distance measuring instrument is 3-5mm, which is called spot measurement so that a compartment dimension measuring result is enabled to be accurate, the whole process is completed without manual measurement, operation is simple, labor and financial resources are saved, measuring precision is great and thus the acquired sample is great in representativeness.

Description

technical field [0001] The invention relates to the field of positioning of vehicle compartments, in particular to a method for laser scanning measurement and positioning of compartments Background technique [0002] Merchant production or purchase of goods requires relevant quality inspection departments to conduct quality inspections before they can be sold or entered into the factory. Specifically, the vehicles transport the commodities produced by the merchants to the sampling base of the quality inspection department, and the staff of the relevant quality inspection department will sample the commodities at the sampling base to check the composition of the commodity and whether the composition of the commodity is qualified. [0003] In the related art, the vehicle sampling equipment uses an ultrasonic sensor to measure and locate the compartment of the vehicle. Specifically, ultrasonic sensors are installed on both sides of the sampling area, and ultrasonic waves are s...
