Embodiment Construction

[0035] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0036] Such as figure 1 As shown, a video image acquisition and shaking processing method provided by an embodiment of the present invention includes the following steps:

[0037] 101. Select an ROI region of interest from a surveillance video image, and determine a preset number of corner points and coordinate values ​​of each corner point from the ROI region.

[0038] Wherein, the preset number may be 2, 3, 4, etc., which is not limited in this embodiment of the present invention. Because the shake occurs on the street lamp where the camera is located, it is a small local shake in the plane, so the embodiment of the present invention detects the amount of shake translation by selecting a small area, which can avoid a large number of calculations for the entire image, It also avoids the matching work of a large numb...

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: selecting an ROI region from a monitoring video image, and determining a preset number of angular points and the coordinate value of each angular point from the ROI region; selecting a de-jitter reference angular point from the preset number of angular points according to the angular point coordinates and the coordinates of edge points in a preset direction in the image; determining a jitter translation amount according to a difference value between the coordinate value of the de-jitter reference angular point in the first frame of image and the coordinate value of the de-jitter reference angular point in any other frame of image; and carrying out jitter removal processing on the vehicle target position according to the jitter offset. 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 system for video image acquisition and shake processing. 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 equipment shaking, which will lead to errors in image acquisition, so the concept of video de-jittering is derived. Video dejitter refers to the use of related algorithms to process the original video sequence collected by video equipment to remove the jitter. The purpose of video image stabilization, on the one hand, is to make people feel comfortable, which is beneficial to manual observation and discrimination, and on the other hand, it is also used as a preprocessing stage for many other subsequent processes, such as detection, tracking and compression. [0003] At present, when performing video de-jittering, the method ...
