Abstract

The invention discloses a vehicle positioning method and system based on a laser device, wherein the method includes: using a laser device installed on the vehicle to detect in real time several reflective columns preset on the equipment to be aligned, so as to obtain each reflective column Relative to the current position information of the laser device; according to the current position information, the preset alignment coordinate system of the reflective column cluster and the actual position information of each reflective column, the vehicle position of the vehicle relative to the equipment to be aligned is calculated. The present invention can quickly determine the vehicle position of the vehicle relative to the equipment to be aligned according to the current position information in real time, and satisfies the precise positioning of the vehicle itself during the continuous running of the vehicle.

Description

technical field [0001] The invention relates to the technical field of vehicle positioning, in particular to a vehicle positioning method and system based on a laser device. Background technique [0002] With the development and popularization of unmanned driving technology, more and more closed or semi-open scenes begin to use unmanned driving technology to assist and support the operation process, and the port environment is one of them. Since one of the characteristics of the machine is that it can work 7×24 hours without interruption, from the perspective of efficiency improvement and cost control, port unmanned truck operation is a future trend and an important means to replace traditional port manual operations, and vehicles Positioning plays an important role in autonomous vehicle operations. [0003] At present, most vehicle positioning methods are to install sensors on the loading and unloading equipment to detect the position of the vehicle during the container lo...
