Abstract

The invention belongs to the technical field of car search, and discloses an augmented reality reverse car search system and method. The augmented reality reverse car search system includes: a parking lot information collection module, a parking lot model building module, and a vehicle positioning module , Vehicle owner dynamic acquisition module, central control module, information feedback module, cloud recognition module, position and direction transformation module, stereo imaging module, AR management module. The present invention obtains the position of the vehicle by setting the vehicle positioning module, determines the general area where the vehicle is located, and then identifies the vehicle through the cloud identification module and the position direction transformation module, which can realize the dynamic information feedback of the vehicle position and the owner's position in the parking lot, That is, when the car owner uses the system to find the vehicle location, he will constantly change the position, direction, etc., and use the three-dimensional registration technology to realize positioning, tracking and stereo imaging, so as to solve the problem of inaccurate positioning information obtained by the existing car-finding system due to signal interference. question.

Description

technical field [0001] The invention belongs to the technical field of car search, in particular to an augmented reality reverse car search system and method. Background technique [0002] At present, with the rapid development of construction and transportation in my country, large-scale underground parking lots have been established to meet people's parking needs, resulting in the difficulty of finding cars. Nowadays, the market has strengthened research on low-cost, simple-to-deploy reverse car-finding systems. For example, augmented reality technology can superimpose virtual images with the real environment, and then help car owners navigate the specific location of the vehicle. Moreover, this paper mainly analyzes the reverse car-finding system and its disadvantages in common large-scale parking lots, expounds the application characteristics of AR technology for reverse car-finding systems in large underground parking lots, and conducts research on the design and practi...
