Embodiment Construction

[0032] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0033] The underwater target tracking method provided by the embodiment of the present invention is applied to underwater tracking equipment, such as figure 1 As shown, the method includes the following steps:

[0034] S110: Acquire a first image and a second image in which a tracking target is recorded.

[0035] Wherein, the shooting time of the first image and the second image is the same, and the shooting angle of view of the first camera for shooting the first image is different from the shooting angle of view of the second camera for shooting the second image;

[0036] S120: Determine a first orientation of the tracking target relative to the underwater tracking device according to the first image and the second image;

[0037] S130: According to the first orientation, determine whether the dista...

Abstract

The embodiment of the invention provides an underwater target tracking method and a device which are applied to underwater tracking equipment, and the method comprises the steps: obtaining a first image and a second image which record a tracking target, and determining a first direction of the tracking target relative to the underwater tracking equipment according to the first image and the secondimage; according to the first orientation, judging whether the distance between the underwater tracking equipment and the tracking target is greater than a preset distance; if the distance between the underwater tracking equipment and the tracking target is greater than the preset distance, operating the underwater tracking equipment at a first speed and the first orientation; and if the distancebetween the underwater tracking device and the tracking target is not greater than the preset distance, operating the underwater tracking device at a second speed according to the orientation, by using the method of the embodiment of the invention to track the underwater target, the target can be identified more effectively, so that the safety of the target is improved.

Description

technical field [0001] The invention relates to the technical field of target tracking, in particular to an underwater target tracking method and device. Background technique [0002] In marine science research, underwater equipment is often used to track and photograph underwater targets (eg, divers). Among them, underwater machine vision, as a general technology, widely assists underwater applications, and plays an important role in robots, drones, etc. [0003] In underwater machine vision, it is often necessary to locate the position of the target in each frame of the image, and target tracking is precisely one of the key technologies. A related underwater target tracking method uses an image acquisition device to shoot the target, so as to track the target according to the captured image. When the image acquisition device is too far away from the target, there is a possibility of tracking failure due to the inability to effectively identify the target, so that the saf...
