Problems solved by technology

However, this calibration method needs to be completed in a specific scenario, and it is only suitable for calibration of vehicles before leaving the factory. When the sold vehicles have technical problems such as image fusion dislocation and inability to splicing into a complete image, the above calibration method is not applicable. Be applicable
This is because, due to various conditions, it usually takes a lot of manpower and material resources to return the problematic vehicle to a specific site of the depot for recalibration. The process is relatively cumbersome and inefficient, which brings a lot of inconvenience to users.

Embodiment 1

[0035] Such as Figure 1-Figure 2 As shown, this embodiment provides a panoramic image calibration method for after-sales vehicles, based on the vehicle panoramic controller and four cameras arranged around the vehicle body, the four cameras can be installed on the front, rear, left, and right sides of the car respectively, or can be selected to set at the four corners of the car.

[0036] A panoramic image calibration method for aftermarket vehicles, specifically comprising the following steps:

[0037] 101. Obtain the unique identification code of each camera.

[0038] Each camera will be set with a unique identification code before leaving the factory. Different cameras have different unique identification codes, which are used as the representative code of the camera. In this technical solution, the camera is a wide-angle camera, and four wide-angle cameras are respectively arranged at four corners of the vehicle, and the ideal fields of view of adjacent wide-angle camer...

Embodiment 2

[0049] This embodiment provides an aftermarket panoramic image calibration device, which includes a memory, a processor, and a panoramic image calibration program stored in the memory and operable on the processor, and the panoramic image calibration program is processed by the processor The panoramic image calibration method for aftermarket vehicles in Embodiment 1 is implemented when the controller is executed. The memory mentioned here includes but is not limited to a storage module inside the vehicle-mounted panoramic controller or a storage unit inside the vehicle-mounted control system, and the processor includes but not limited to a processing unit inside the vehicle-mounted panoramic controller or a vehicle-mounted processing unit.

Abstract

The invention relates to a panoramic image calibration method for an after-sales vehicle, which is based on a vehicle-mounted panoramic controller and a plurality of cameras arranged around a vehicle body, and comprises the following steps: acquiring a unique identification code of each camera; judging whether record information matched with the unique identification code of each camera is stored in the vehicle-mounted panoramic controller or not, and if so, ending calibration; otherwise, acquiring calibration data in each camera; judging whether the calibration data in each camera is consistent or not, and if so, importing the calibration data into the vehicle-mounted panoramic controller to finish calibration setting of the vehicle-mounted panoramic controller; otherwise, ending the calibration. According to the panoramic image calibration method, after-sales re-calibration of the vehicle-mounted panoramic controller can be completed by reading the ex-factory calibration data stored in the camera, the vehicle does not need to be returned to the factory for calibration again, the after-sales calibration process is simplified, the calibration efficiency is improved, the calibration cost is obviously reduced, great convenience is brought to a user, and the method has important practical value.

Description

technical field [0001] The invention relates to the technical field of electronic automobile products, in particular to a panoramic image calibration method for after-sales vehicles. Background technique [0002] With the continuous development of living standards and science and technology, cars have gradually become an indispensable part of people's daily life. At present, the panoramic image assistance system has been generally installed in the vehicle. The panoramic image assistance system is mainly a set of 360-degree panoramic fusion images observed around the vehicle body through the vehicle navigation display, which can effectively help the owner understand the blind spot of the vehicle and enable the driver to drive. It can be safer and more convenient when driving in a car. The 360-degree panoramic fusion image generally calculates the position and attitude of the camera in the real world through the calibration function (according to the feature points of the ima...
