Embodiment Construction

[0012] Preferred embodiments of the present invention are described below, and it should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0013] According to an embodiment of the present invention, a method for estimating the running direction of an image in a dynamic video is provided, including:

[0014] ⑴In the field of view shooting space where the moving image is to be acquired, the circumference is divided into 4 work areas, and each work area is equipped with 2 groups of cameras, and the angle between the 2 groups of cameras is 30 degrees; the 4 work areas are in 4 different height, and work at the same time;

[0015] (2) The images captured by multiple cameras in the 4 working areas are transmitted to the background controller in real time; the controller divides and compares the real-time transmitted images in rows and columns, obtains the m...

Abstract

The invention discloses a method for predicting an image moving direction in a dynamic video. The method comprises the steps that: (1) in a visual field shooting space of moving images to be obtained, the circumference is divided into four working regions, wherein two groups of cameras are arranged in each working region, an included angle between the two groups of cameras is 30 degrees, and the four working regions work simultaneously at 4 different heights; and (2) images shot by the plurality of cameras in the four working regions are transmitted to a background controller in real time, the controller carries out row-column segmentation comparison on the images transmitted in real time, the moving trends of the images shot in the four working regions are obtained, and a gradient algorithm is used for pre-estimating the moving directions of corresponding moving images. The method for predicting the image moving direction in the dynamic video overcomes the defects in the prior art that the manual labor amount is large, the cost is high and the reliability is poor and has the advantages of low manual labor amount, low cost and good reliability.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a method for estimating running directions of images in dynamic videos. Background technique [0002] Motion images include displacement-time images and velocity-time images, where both displacement and velocity are vectors, and vectors contain magnitude and direction: displacement-time images, velocity-time images, and areas enclosed by images and coordinate axes. [0003] In the prior art, moving images are mainly obtained by cameras, which need to work in multiple directions without uninterrupted power supply, high cost and poor reliability, requiring multiple workers to work together at the same time. [0004] During the process of realizing the present invention, the inventors found that the prior art at least has defects such as large amount of manual labor, high cost and poor reliability. Contents of the invention [0005] The object of the present invention...
