Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] Figure 4 It is a flow chart of the calibration method of the panoramic view system based on the Internet of Vehicles provided by the embodiment of the present invention. see Figure 4 , the example includes:

[0030] 401. The terminal of the Internet of Vehicles sends an image acquisition command, so that the main controller acquires the distorted images collected by multiple cameras configured on the vehicle to be calibrated at the calibration station;

[0031] The image acquisition instruction can be sent by artificially controlling the IoV terminal.

[0032] The plurality of cameras may be fisheye cameras, preferably, there are four cameras, which are respectively located at the front, rear, left, and right sides of the v...

Abstract

The invention discloses a car networking based panoramic all-round system calibration method, device and system and belongs to the technical field of car electronics. The method includes that a car networking terminal sends an image acquisition instruction to enable a main controller to acquire distorted images acquired by multiple cameras configured to a to-be-calibrated car on a calibration station; the car networking terminal transmits the collected distorted images to a car networking platform through a network, the car networking platform calibrates the car after the car leaves the current station, calibration parameters are acquired, and further the main controller processes the distorted image according to the calibration parameters to obtain a panoramic image surrounding the car; the car networking terminal prompts a driver to leave for a next station. Based on car networking, calibration is performed on the background by only image acquisition and transmission on the calibration station. Calibration time of the calibration station is saved, and production efficiency of a car plant is improved; image transmission equipment and calibration personnel needed for field calibration are reduced, and cost is lowered.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a method, device and system for calibrating a panoramic view system based on the Internet of Vehicles. Background technique [0002] The Internet of Vehicles is a segmented application of the Internet of Things in the automotive field. It is the only way for the mobile Internet and the Internet of Things to develop into business essence and depth. Devices interact with each other to realize a dynamic mobile communication system for communication between vehicles and the public network. It can realize information sharing through vehicle-to-vehicle, vehicle-to-people, vehicle-to-road interconnection, collect information on vehicles, roads and the environment, and process, calculate, share and securely release the information collected from multiple sources on the information network platform , effectively guide and supervise vehicles according to different functiona...
