Method for positioning and navigating automobile in parking lot through camera

Abstract

The invention relates to the technical field of automobile positioning, and particularly relates to a method for positioning and navigating an automobile in a parking lot through a camera. The methodcomprises the steps of firstly, constructing a parking lot into a navigation map mode; defining the coordinates of each parking space and each line; inputting the map into a host, moving the vehicle to different points from an entrance, using the camera to calculate the XYR data of the vehicle according to the size of the image and the feature points, using the cloud server host to upload the parking data to a cloud server, so that after a mobile terminal receives the information, the mobile terminal can use the parking space of the parking lot as a target for navigation. According to the invention, the license plate information and the vehicle size data are obtained through the camera at the entrance and then are sent to a system for virtually constructing a shape image, a minimum numberof cameras are used to track and attach, and the position data of the movement and parking after the vehicle enters the parking lot is obtained, so that the related information required by the vehicleparking can be obtained with the extremely low equipment investment cost.

Description

Technical field [0001] The present invention relates to the technical field of car positioning, in particular to a method for car positioning and navigation in a parking lot through a camera. Background technique [0002] With the continuous development of my country's economy and the improvement of living water products, automobiles have entered thousands of households, and parking has become one of the problems facing urban management. At present, large-scale underground parking lots are set up in public places such as residential quarters, office buildings, shopping malls, railway stations, airports, etc., which meet the requirements of most cars. However, general underground parking lots do not have GPS or Beidou positioning systems. So there are the following problems in the real stage: [0003] The first is that the vehicle enters the underground parking lot and cannot be navigated; the second is that the vehicle cannot know where the empty parking space is after entering th...

AI Technical Summary

Problems solved by technology

[0003] One is that the vehicle enters the underground parking lot and cannot navigate; the other is that the vehicle cannot know where the empty parking space is after entering the garage, and the signs and lights cannot be clearly identified; the third is that the original parking position cannot be found when returning to search for the car after parking for too long , It takes a lot of time to search repeatedly. If you use the car search opportunity to increase costs, and the operation is inconvenient, it is a waste of time; third, the number of parking lots near the destination is not clear, and the occupancy of each parking lot is not clear. The parking space takes too much time; the fourth is that the license plate cannot be recognized by the parking sensor, and the recognition of the license plate for each parking space will inevitably cost a huge amount of hardware expenditure; the current parking management system of the parking lot does not have fire protection and the flooding system requires additional huge expenditures
