Abstract

The invention discloses a long-time fish tracking method, which belongs to the field of computer application. The method comprises the following steps: obtaining a fish video, wherein the fish video comprises a preset fish image and a fish image to be tracked, and the preset fish image comprises a preset feature area and a preset target area; according to a real-time compression tracking algorithm, the continuous frame direction consistency of a movement target and the fish video, obtaining the feature area of the fish image to be tracked; judging whether the feature area of the fish image to be tracked is effective or not; and if the feature area of the fish image to be tracked is effective, calculating the target area of the finish image to be tracked according to the feature area, the preset feature area and the preset target area. The long-time fish tracking method obtains the feature area according to the real-time compression tracking algorithm, the continuous frame direction consistency of the movement target and the fish video, and avoids a drifting problem in a long-time tracking process of the fish video.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a long-time fish tracking method. Background technique [0002] With the continuous development of machine vision technology, object tracking has become an important research direction in video analysis. The target tracking of the fish's movement process can effectively extract the movement trajectory of the fish, and then evaluate its movement characteristics and activity in different living environments. This has important guiding significance for fishway design for migratory fish. In the process of fish target tracking, it is necessary to take a long-term motion video of the fish, track the motion position of the fish in the video, and obtain the motion law of the fish. [0003] In the existing target tracking technology, swisTrack software is used for target tracking, such as ants, billiard balls, cockroaches, etc. First, the background template provided by the user is ...
