Embodiment 1

[0070] This embodiment relates to a parking area without a parking hall and a corresponding system, such as figure 1 shown, including:

[0071] The camera 2 and camera fixed structure 4 erected around the parking area 1 are used to obtain the image, focal length and time of the parking area, and send it to the data processing module, as well as the fixed camera 2;

[0072] The angle detection sensor 3 connected together with the camera 2 records the angle and time of camera rotation, and sends it to the data processing module;

[0073] The data processing module is used to establish a coordinate system for the parking area and record the coordinates of each camera; establish a model in the coordinate system through the image, the focal length corresponding to the image and the angle of rotation; determine the position of the parking robot when transporting the vehicle according to the vehicle model The best position, and send it to the parking robot controller; used to collec...

Abstract

The invention belongs to the technical field of positioning technologies and intelligent parking robots, and discloses a license plate-based parking hall-free intelligent parking system. The system comprises: cameras and camera fixing structures, which are erected on the periphery of a parking area; angle detection sensors connected with the cameras; a data processing module; a parking space obtaining module; a parking robot provided with a parking robot controller; and a management platform. Vehicles which are randomly parked can be carried to designated parking spaces only through the parking robot without a parking hall; the field structure is simple, manufacturing is convenient, no equipment needs to be arranged in the parking area, the parking hall of a complex structure does not needto be built, and only part of equipment is erected around the parking area; a wheelbase is determined according to a license plate, the wheelbase of each vehicle does not need to be measured, and data processing is simple; graphs are obtained through the cameras, so the precision is high, and errors are small; and through calculation of a cloud data server, the response is fast, and the waiting time is short.

Description

technical field [0001] The invention belongs to the field of positioning technology and intelligent parking robot technology, and in particular relates to an intelligent parking system based on a license plate that does not require a parking hall. Background technique [0002] The parking hall is the vehicle pick-and-place room of a large unmanned intelligent parking lot. It is used for automatic pick-and-place of vehicles by drivers, automatic pick-and-place of vehicles by parking robots, and automatic measurement of vehicle appearance information. It is the link between drivers and intelligent parking lots. The vehicle handover room and the automatic measurement room for vehicle appearance information. [0003] Existing parking halls generally have peripheral structures such as columns, ceilings, and rolling doors. Measuring devices such as laser radar ranging devices and camera ranging devices are installed on these peripheral structures to measure the appearance of vehic...
