Swimming pool anti-drowning multi-camera space fusion method and device, computer equipment and storage medium

Abstract

The embodiment of the invention discloses a swimming pool anti-drowning multi-camera space fusion method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a reference camera image and a to-be-registered camera image; calibrating internal parameters of the reference camera and the to-be-registered camera; preprocessing the reference camera image and the to-be-registered camera image to obtain a local world coordinate system; calculating a relative pose between the reference camera and the to-be-registered camera; associating a plurality of cameras through the relative poses to establish a global unified world coordinate system; determining the position of each camera under the global unified world coordinate system to obtain the spatial pose of each camera; and splicing the images of the cameras according to the spatial poses of the cameras. By implementing the method provided by the embodiment of the invention, the contents shot by the plurality of cameras for shooting the water surface of the swimming pool can be spatially fused, so that the all-around supervision of the swimming pool is realized, and the anti-drowning supervision accuracy is improved.

Description

technical field [0001] The invention relates to a computer, and more specifically refers to a swimming pool anti-drowning multi-camera space fusion method, device, computer equipment and storage medium. Background technique [0002] With the development of sports, people's enthusiasm for participating in sports is increasing, but swimming, one of the popular sports, has become the sport with the highest incidence of safety accidents. According to incomplete statistics released by the Ministry of Health, about 57,000 people die in drowning accidents in my country every year, of which 56.04% are teenagers, making them the number one cause of death among teenagers, and China's drowning death rate is the highest in the world. [0003] The existing technology installs underwater cameras around and at the bottom of the swimming pool, and uses an algorithm to determine whether the swimmer's movements are swimming normally or in a state of drowning and struggling. However, the numb...

Problems solved by technology

However, the number of cameras installed is mostly one. Although there are also cases where multiple cameras shoot around and at the bottom of the swimming pool, when performing algorithm analysis, the content captured by a single camera is analyzed separately. The problem of dead angles leads to a low accuracy rate of anti-drowning supervision
