Problems solved by technology

[0002] The 360-degree surround view system requires the calibration process of the camera, and the existing calibration process generally requires manual participation
Third, calibration personnel work for a long time, which will reduce the efficiency and accuracy of point selection
Therefore, the manual calibration process is not suitable for a large number of surround view installations

Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] In the embodiment of the present invention, a 360-degree surround view system online automatic calibration system, a basic premise of automatic calibration is that the positions and angles of the cameras installed on a vehicle type are basically the same, and the source of difference between the cameras of different vehicles of the vehicle type is only In order to install the error, an automatic calibration site is required for automatic calibration. Eac...

Abstract

The invention discloses an online automatic calibration system for a 360-degree panoramic system. A basic premise of automatic calibration is that cameras mounted on vehicles of one type are consistent in position and angle; a source of difference among the cameras of different vehicles of the type is only a mounting error; and during automatic calibration, a panoramic ECU is arranged in each vehicle and an automatic calibration algorithm runs in the panoramic ECU. The calibration system has the beneficial effects that firstly, no personnel participate in calibration of all vehicles of the type in the subsequent process except that the personnel need to participate in first-time calibration, namely, the vehicles of one type are manually calibrated for one time only; and secondly, all subsequent calibration processes are vertical view calibration processes except that the first-time calibration is single-view calibration.

Description

technical field [0001] The invention relates to an online automatic calibration system, in particular to an online automatic calibration system for a 360-degree surround view system. Background technique [0002] The 360-degree surround view system requires a camera calibration process, and the existing calibration process generally requires manual participation. The commonly used calibration method is: first lay the calibration cloth and calibration plate on the ground, then use the camera to take pictures, manually select the marked points in the photos, and finally calculate and generate the top view. There are some disadvantages in the calibration process with human participation. First, it is necessary to manually select calibration points after each photo is taken, which is inefficient. Second, manual selection of calibration points has a certain degree of subjectivity. Third, the long-term work of the calibration personnel will reduce the efficiency and accuracy of...
