Abstract

The present invention provides an image processing device, an image correction method, an image correction system, a calibration point search method and a calibration point search system. The calibration point search method includes the following steps that: after a first preset calibration point is found out in a first calibration region image, the image coordinates of the first preset calibration point are acquired; a corresponding conversion matrix is generated according to the pre-stored physical coordinates of the first preset calibration point; the conversion matrix is utilized to convert a second calibration region image, so that a second calibration region converted image can be generated; a second preset calibration point is searched in the second calibration region converted image; and the image coordinates of the second preset calibration point corresponding to the second calibration region image are obtained according to the conversion matrix. With the calibration point search method of the invention adopted, when the second calibration region image is small, and the deformation of the second calibration region image is large, and as a result, a calibration point cannot be distinguished, and the image coordinates of the calibration point corresponding to the second calibration region can be obtained accurately and quickly, and therefore, images captured by cameras can be corrected accurately and efficiently corrected, and smoother seamless stitching of the images captured by the cameras can be realized.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image processing device, image correction, calibration point search method and system. Background technique [0002] In recent years, the advanced driving assistance system based on the surround view camera (also called the surround view ADAS system) has been accepted by more and more users. By installing wide-angle cameras on the front, rear, left, and right sides of the car, the images around the car body are collected, and after algorithm analysis and processing, the driver is provided with various advanced driving assistance functions including panoramic parking assistance, lane departure warning, and blind spot vehicle detection. The active safety of automobile is of great significance. [0003] Before starting to use the surround view ADAS system, it is necessary to establish the correspondence between image coordinates and physical coordinates. The establishmen...
