The invention discloses a positioning method and apparatus of a vehicle, and a computer readable storage medium. The positioning method of the vehicle includes: obtaining at least three laser beam points received by a target vehicle through a laser receiver when receiving a vehicle positioning instruction; and determining a current position of the target vehicle according to interval distances between the laser beam points and a preset space distribution rule of laser beams. According to the method and apparatus, current position information corresponding to the target vehicle can be determined through the preset space distribution rule of the laser beams and measurement of the interval distances between the laser beam points received by the target vehicle. Therefore, the position information of the target vehicle can be determined through the interval distances between the laser points, the measurement of intensity information of the laser points and time information of the nanosecondscale can be avoided, the measuring cost is reduced, the positioning accuracy is improved, and the technical problem of difficult realization of high-precision positioning in places with weak GPS signals is solved.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a vehicle positioning method, device and computer-readable storage medium. Background technique [0002] Traditional vehicle positioning is generally achieved by obtaining information on the geographic location of the vehicle through a similar system such as the Global Positioning System (GPS) or a triangulation system, thereby realizing vehicle positioning. However, the above-mentioned positioning systems all use GPS and other signals for positioning and measurement. GPS and other signals are easily affected by obstructions. For example, when bridges, tunnels, and other overhead objects temporarily block or hinder the communication of the system, certain The positioning error of the amplitude reduces the positioning efficiency. Even in some areas with dense buildings, it is difficult to achieve high-precision positioning due to the weak GPS signal. Contents of ...
