Embodiment

[0028] In order to achieve the above purpose, the swimming pool drowning detection method based on spatio-temporal neighborhood features involved in this embodiment specifically includes the following process steps:

[0029] 1. Using the features of spatio-temporal fragments for background modeling:

[0030] First, the video image sequence of the swimming pool is collected in real time by a camera installed above the water surface, and is transmitted to a computer connected to the camera. order measurement standard; set the intensity set of N pixels contained in the neighborhood of pixel point p at time t as S(p,t)={x 1 ,x 2 ,....,x N}, first cluster these observations from the pixels in the model area and in the process of background learning, and then obtain a compact model by comparing the similarity of the two observations; by dividing the neighborhood segment of the pixel point P Defined as an ordered pixel subset intensity in the neighborhood, such as I({1,4,12}; P) ref...

Abstract

The invention belongs to the technical field of video monitoring, and relates to a swimming pool drowning detection method based on spatio-temporal neighborhood features. Based on the image sequence captured by the swimming pool camera, the above-mentioned images are processed by a computer to monitor and detect. The main process includes the following steps: One is background modeling using the features of spatio-temporal segments, the other is establishing a database of observations to determine the strength of the field around each pixel, and the third is performing foreground detection, including pixel processing and Judging the position of the limbs of the person in the swimming pool by analyzing the body of the detected prospect. When the analysis result meets all the characteristics of drowning, it is judged as drowning. The fourth is to call the police for rescue. When a drowning person is detected, the alarm system is activated. Rescue in time. The monitoring and detection method is scientific and accurate. It can accurately locate the person who fell into the water and give an alarm, which improves the safety of the swimming pool. Only grayscale images are processed, reducing the amount of original data.

Description

Technical field: [0001] The invention belongs to the technical field of video monitoring, and relates to a method for monitoring and early warning of swimming pool drowning behavior, in particular to a swimming pool drowning detection method based on spatio-temporal neighborhood features. Background technique: [0002] Swimming is a very common and effective way of exercising, and it is very popular among people. With the economic development and social progress of our country, there are more and more indoor swimming pool facilities, but the safety of swimming pools cannot be ignored. Scholars often lose their balance and choke in the water because they are not familiar with the nature of water, which may cause drowning accidents. Some swimmers who have learned to swim are also prone to drowning accidents due to cramps, sudden collisions, sudden illnesses, and mental stress. A drowning situation has occurred. Most of the detection systems in domestic swimming pools rely on ...
