Embodiment Construction

[0043] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0044] like figure 1 As shown, a method for processing video image capture and shaking provided by an embodiment of the present invention includes the following steps:

[0045] 101. Select a preset reference corner point from the first frame of surveillance video image, and generate a ROI area according to the coordinates of the preset reference corner point.

[0046] For this embodiment of the present invention, step 101 may specifically include: selecting a corner point from the surveillance video image that is located in the background area, the pixel of the background area image is single, and the angle of the corner point is an acute angle as the first frame of surveillance video The preset reference corner point of the image; the step of generating the ROI region according to the coordinates of the preset reference corner...

Abstract

The invention discloses a video image acquisition jitter processing method and system, and relates to the field of intelligent parking management, and the method comprises the steps: firstly, selecting a preset reference angular point from a monitoring video image, and generating an ROI region according to the coordinates of the preset reference angular point, and then calculating a final jitter translation amount based on the de-jitter reference angular point coordinates in the ROI region of the adjacent image frames and the jitter translation amount compared with the first frame, and completing an image de-jitter process based on the jitter translation amount. As only a small part of ROI is selected from the whole image as the original image for jitter removal, operation processing does not need to be performed on the whole image, the efficiency of image jitter removal can be improved, the processing time can be shortened, and real-time jitter removal of the video vehicle position in a radar video data fusion algorithm is realized.

Description

technical field [0001] The invention relates to the field of intelligent parking management, in particular to a method and a system for jitter processing for video image acquisition. Background technique [0002] During the image acquisition process of the camera, due to the influence of the surrounding environment, weather and other factors, there will be a phenomenon of equipment shaking, which will lead to errors in image acquisition, so the concept of video de-shaking is derived. Video de-shake refers to using related algorithms to process the original video sequence collected by the video device to remove the jitter. The purpose of video image stabilization, on the one hand, is to make the eyes feel comfortable and conducive to manual observation and discrimination, and on the other hand, it is also used as a preprocessing stage for many other subsequent processing, such as detection, tracking and compression. [0003] At present, affine transformation is usually used ...
