Embodiment Construction

[0029] Such as figure 1 As shown, the steps implemented by the present invention consist of calculating trajectory splitting energy, calculating pipeline correlation, calculating trajectory collision energy, calculating time consistency energy and synthesizing video summaries. The specific steps are as follows:

[0030] 1. Calculate the estimated splitting energy

[0031] Calculate the trajectory splitting energy, trajectory collision energy, and time consistency energy between pipelines, adjust their respective weights according to user needs, and add them up.

[0032]

[0033] where E s represents the trajectory splitting energy, Ec represents the trajectory collision energy, E t Denotes temporal consistency energy, B denotes the set of motion pipelines, α, β and ε denote weight values ​​set according to user needs, where β increases and collisions in video summaries decrease, and vice versa.

[0034] Trajectory splitting energy. In the original video, if two moving ...

Abstract

The invention relates to a target-based moving object arrangement method enabling energy constraint minimization. The method mainly comprises the following steps: 1) performing occupied distribution space processing for all movement tracks by considering sizes and paths of objects; and 2) offering three energy definitions including track split energy, track bump energy and relative time consistency energy, summing the three types of energy on the basis of a weight ratio, and a track and an arrangement mode that enable a minimal sum value are obtained through an energy constraint minimization algorithm. Through the above method, a re-arranged abstract video can be quickly browsed without information loss, space, time and logic relations of moving objects in an original monitor video are stored, a video compression ratio is increased, and users can quickly and logically view a monitor video.

Description

technical field [0001] The invention relates to a method for arranging moving objects based on object-based energy constraint minimization, and belongs to the technical field of video surveillance. Background technique [0002] Due to the advancement of science and technology and the improvement of the economic level, urban surveillance cameras are spread all over every corner, and the resulting surveillance videos have also increased exponentially, especially 24-hour surveillance videos. However, it is time-consuming and labor-intensive to search and browse a large number of videos. On the one hand, most surveillance videos contain few interesting object movements, such as streets with few people passing by or the movement of people and vehicles on the road in the middle of the night is very sparse. To find a moving object of interest in a large number of videos, it takes as much time as recording to browse the surveillance video, so most of the surveillance videos have nev...
