Embodiment 1

[0054] Such as figure 1 , 2 3. The multi-target tracking and positioning system in the parking lot mainly includes 1 wireless synchronization controller, m*n wireless positioning base stations, body positioning tags, car search tags, inertial navigation modules, mobile power modules, and wireless modules; in the positioning system Among them, the wireless positioning base stations are distributed throughout the parking lot. There are two modes of fixing the positioning base stations. The base station can be fixed on the ceiling by the ceiling installation method, or the base station can be fixed on the side wall of the wall by using the supporting mounting bracket. , it should be noted that the distance between two positioning base stations should not exceed 30 meters, the installation height of the positioning base station should be greater than 2 meters, and the distance from the wall should not be less than 0.3 meters, which can not only improve the positioning accuracy, bu...

Abstract

The invention discloses a multi-target tracking and positioning system for an indoor parking lot, and belongs to the field of multi-target tracking and positioning. The system comprises a UWB positioning system and a vehicle body positioning device, the UWB positioning system comprises a wireless synchronous controller and a wireless positioning base station, and the vehicle body positioning device comprises a vehicle body positioning label, an inertia navigation module, a wireless module and a portable power source module; the data output by the inertia navigation module are sent to an upper computer system through the wireless module, meanwhile, the vehicle body positioning label sends a signal to the wireless positioning base station, the wireless positioning base station transmits the data to the wireless synchronous controller, the wireless synchronous controller sends the signal to an upper computer, and the upper computer system obtains target position data and posture data, determines specific vehicle body position and posture information through fusion operation and sends the information to a mobile client. The combined positioning system breaks through a positioning mode limited by environments in the prior art, and improvement in the aspects of spatiality, real-time performance, quantitative performance and precision is achieved.

Description

technical field [0001] The invention relates to a wireless positioning system, in particular to a tracking and positioning system which combines ultra-broadband wireless positioning and inertial navigation and can provide precise navigation for multi-target vehicles in a parking lot, belonging to the field of multi-target tracking and positioning. Background technique [0002] With the rapid development of my country's economy, in recent years, the number of private cars has increased exponentially, and users' demand for parking in commercial areas, hospitals, schools and other places has greatly increased; traditional small and medium-sized parking lots have It cannot meet the needs of the public, so large parking lots are built in many places. However, due to the large parking space, many vehicles, and difficult to distinguish directions, users can only drive around in the parking lot to find a vacant space and finish their work. It is another troublesome thing to find your ...
