Problems solved by technology
In recent years, with the popularity of water sports and the improvement of safety awareness, more and more experts and scholars have paid more and more attention to water target tracking. Because the background environment and target movement form of water target tracking are different from land target tracking, The resulting problems also have distinct characteristics, which are suitable for the tracking method under the attached ring seam, but cannot achieve good results under the water ring cable

The invention discloses a search algorithm for a water rescue robot. The search algorithm comprises the steps of: step 1, laying the water rescue robot in a rescue area; step 2, manually stopping thewater robot after the water robot arrives at a designated area, recording GPRS coordinate positions GX and GY of the current position, setting the search length and width by taking the parking point as a focus, and delimiting a target rescue area for the rescue robot; step 3, starting to search in a defined range; and 4, defining a search range. Rapid and efficient search of a search range can berealized by combining a Mean shift algorithm and a GPRS positioning technology. According to the method, a preprocessing method of a plurality of image pixels is provided through comprehensive analysis of water video images, and on the basis, a new thought is provided for water human body target tracking according to an immersion type shielding rule obtained through a large number of experiments,so that the purpose of improving the target tracking effect is achieved.
Description
technical field [0001] The invention relates to the field of water rescue, in particular to a search algorithm for a water rescue robot. Background technique [0002] As an important branch in the field of computer vision, water sports object tracking has been widely used in the field of water rescue. In recent years, with the popularity of water sports and the improvement of safety awareness, more and more experts and scholars have paid attention to water target tracking. Because the background environment and target movement form of water target tracking are different from land target tracking, The resulting problems also have distinct characteristics, which are applicable to the tracking method under the attached ring seam, but cannot achieve good results under the water ring cable. How to deal with various disturbances of the complex ring slope on the water, solve the occlusion problem, and ensure a good tracking effect are the focus of current research. Contents of t...
