Illegal dog walking event detection method and device based on monitoring video

Abstract

The invention discloses an illegal dog walking event detection method based on a monitoring video, and the method comprises the following steps: A, carrying out the detection of a dog and a person in an image frame, and judging that the state is normal if no dog is detected, and returning; if no dog exists, judging that the dog is not tied with the rope and returning; otherwise, entering the step B; step B, estimating the distance between the person and the dog and judging whether the distance exceeds a distance threshold value or not, if so, judging that the dog is not tied with the rope and returning; otherwise, entering step C; C, intercepting an image containing the dog, inputting the image into the dog rope tying recognition model, and if the output is that the dog is tied with the rope or the dog is not tied with the rope, outputting and returning the result; otherwise, entering the step D; and step D, finding out k persons closest to the dog, intercepting a maximum detection frame image, inputting the maximum detection frame image into the person-dog relation identification model, and judging whether the dog is tied with a rope or not according to model output. The invention further discloses an illegal dog walking event detection device based on the monitoring video.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a monitoring video-based detection method for illegal dog-walking events. Background technique [0002] With the development of society, more and more people began to keep dogs as pets, followed by uncivilized behaviors such as walking dogs without leashes, which also seriously disturbed others. Animal Epidemic Prevention Law clearly lists such behaviors as illegal behaviors. For such illegal activities, if the traditional methods of human monitoring and dissuasion are adopted, a large amount of manpower will be required, which is actually not feasible. If the high-altitude security cameras in the existing streets can be used to detect illegal dog-walking behavior, not only real-time monitoring can be achieved, but also manpower and material costs can be saved, and equipment maintenance and repair are also very easy. The illegal dog walking detection system o...

Problems solved by technology

However, the existing disclosed technology mainly detects and locates people and dogs separately, and cannot identify or effectively identify whether the dog is on a leash and the relationship between the person and the dog, that is, whether the person is leading the dog.
