Problems solved by technology

[0003] A variety of solutions have been proposed for the reverse car search problem in the parking lot. For example, the RFID-based reverse car search system needs to install RFID card readers on both sides of the driveway and in parking spaces during design, and users need to carry them with them. The radio frequency card is used to find the car, which increases the design cost and difficulty
[0004] There are also literatures that propose a reverse car-finding system based on video image processing technology and license plate recognition technology. Compared with manual car-finding and card-swiping car-finding, this car-finding method has been greatly improved, but the system is relatively expensive , not easy to popularize and promote

Abstract

The invention discloses a parking lot vehicle trajectory tracking method and system based on an ultrasonic time sequence. By means of the parking lot vehicle trajectory tracking method based on the ultrasonic time sequence, vehicle information and implementation path information can be timely and efficiently acquired; according to the acquisition method, ultrasonic detectors are used for collecting information, data are sent to a parking lot management server through a communication network, and the server allocates parking space and plans a route for a vehicle and gives light guide. The vehicle position is detected through the ultrasonic detectors, vehicle trajectory tracking and positioning are realized, the deployment, operation and maintenance cost of the system is reduced and popularization is facilitated.

Description

technical field [0001] The invention relates to a method and system for tracking vehicle tracks in a parking lot based on ultrasonic time series. Background technique [0002] With the development of the economy and the improvement of people's living standards, there are more and more urban vehicles, and the construction scale of the parking lot is also expanding day by day. The internal pattern of the parking lot is criss-cross, with many entrances and exits, and the situation of "difficulty finding a car" has become more and more prominent. [0003] A variety of solutions have been proposed for the reverse car search problem in the parking lot. For example, the RFID-based reverse car search system needs to install RFID card readers on both sides of the driveway and in parking spaces during design, and users need to carry them with them. The radio frequency card is used to find the car, which increases the design cost and difficulty. [0004] There are also literatures th...
