Problems solved by technology

[0004] However, the use of cameras to collect two-dimensional images has problems such as short effective detection distance, difficulty in accurately identifying human bodies at night or in dark environments, and easy disclosure of privacy.
Therefore, the application scenarios of human behavior recognition technology are greatly limited and cannot be widely used

Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0055] The recognition method of human behavior provided by this application can be applied to such as Figure 1a shown in the application environment. Among them, the recognition device of human behavior can include a laser radar and a recognition chip set at the same place. The dense point cloud data is obtained from the monitoring of the laser radar, and the dense point cloud data is sent to the recognition chip, and the recognition chip recognizes human behavior based on the dense point cloud data. .

[0056] can also be applied as Figure 1b shown in the application...

Abstract

The present application relates to a human behavior recognition method, device, computer equipment and storage medium. The method includes: acquiring dense point cloud data monitored by lidar; determining the movement trajectory of key points of the human body according to the dense point cloud data; and identifying human behavior according to the movement trajectory of the key points of the human body. Since lidar has the advantages of high precision, long detection distance, and not being affected by light, the embodiment of the present invention can realize accurate identification in various indoor and outdoor scenes around the clock; moreover, the dense point cloud data monitored by lidar does not include color Image information, so it can better protect the privacy of the tested person, and can make the human behavior recognition technology widely used.

Description

technical field [0001] The present application relates to the technical field of behavior recognition, in particular to a human behavior recognition method, device, computer equipment and storage medium. Background technique [0002] With the development of computers, human behavior recognition technology has gradually penetrated into people's work and life. For example, pedestrian warning system using human behavior recognition technology, smart elderly care, smart anti-theft, etc. [0003] At present, human behavior recognition technology is usually based on two-dimensional images collected by cameras for recognition. For example, the camera collects two-dimensional images of intersections, and identifies whether there are violations of traffic rules (such as climbing guardrails and running red lights) from the two-dimensional images. [0004] However, the use of cameras to collect two-dimensional images has problems such as short effective detection distance, difficulty...
