Formation detection method and device for motion matrix of large-scale activity

Abstract

The invention provides a formation detection method and device for a motion matrix of a large-scale activity, and the method comprises the steps: obtaining a target video of a target motion matrix in a target environment; generating a jitter factor corresponding to a target video frame based on the target video frame in the target video and the diagonal gray projection standard array; and under the condition that the jitter factor is lower than a target jitter threshold, generating a target image of the target motion matrix based on the target video frame. According to the formation detection method of the motion square matrix of the large-scale activity, the jitter factor is generated based on the target video frames in the target video and the diagonal gray projection standard array, and the target video frames are screened based on the jitter factor so as to retain the target video frames with relatively low jitter amplitude, and the formation detection accuracy of the motion square matrix of the large-scale activity is improved. And the target video frame with relatively low jitter amplitude is processed to generate the target image of the target motion square matrix, so that the imaging definition is effectively improved, and the detection result can be improved.

Description

technical field [0001] The invention relates to the technical field of image processing, and in particular, to a method and device for formation detection of a large-scale moving square matrix. Background technique [0002] The real-time detection of moving squares based on video images in large-scale events is mainly to capture video images through panoramic cameras set up at high positions in outdoor venues, and to perform real-time detection of large-area moving squares. However, in the related art, since the photographing equipment (especially outdoors) is easily affected by external factors such as strong wind or shaking of the support frame and so on, shaking occurs, which causes problems such as shaking and ghosting of the video picture, and causes the positional displacement of the objects in the picture. Picture distortion affects the clarity of the image, thus affecting the detection results. SUMMARY OF THE INVENTION [0003] The invention provides a formation d...
