Method and system for capturing motion posture of single target human body in multi-person environment

Abstract

The invention discloses a method and system for capturing the motion posture of a single target human body in a multi-person environment, and the method comprises the following steps: collecting an image from a dynamic visual angle, and selecting a target human body; calculating the positions of multiple people and the three-dimensional skeleton of the target human body according to the acquired images; estimating the positions of multiple persons and the posture of the target human body at the next moment, and obtaining an optimal observation visual angle; planning an unmanned aerial vehicleflight path according to the optimal observation visual angle, controlling the unmanned aerial vehicle to fly according to the unmanned aerial vehicle flight path to reach the optimal observation position, and ensuring the optimal observation visual angle. The optimal observation visual angle can be calculated in real time, mutual shielding among multiple human bodies and self-shielding of the target human body are effectively avoided, the capture precision of the target human body motion posture is improved, and the method is simple and easy to implement.

Description

technical field [0001] The present invention relates to the technical field of moving human body tracking and motion capture application technology, in particular to a method and system for capturing the motion posture of a single target human body in a multi-person environment. Background technique [0002] Moving human body tracking and motion capture technology is an important technical means to obtain human activity information and analyze the law of target human body movement in natural and social scenes. Real-time and accurate human motion capture is widely used in security monitoring, virtual reality, and film production. [0003] The traditional human motion capture method is to collect the signal sent by the special equipment worn on the captured human body, and then calculate the three-dimensional motion information of the human body, but this method is not suitable for the human body motion capture requirements in natural scenes. The vision-based markerless motio...

Problems solved by technology

However, in actual application scenarios, especially when performing human body capture tasks in outdoor environments, the construction of dense cameras will have high costs and is easily restricted by the environment, so it is not feasible
