Embodiment Construction

[0042] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0043] The invention discloses a mobile platform-based large-scale outdoor human body posture reconstruction technology, which enables real-time self-calibration of a camera on the mobile platform to reconstruct the outdoor large-scale human body posture in real time. Without the need for a tedious manual calibration process, it is possible to reconstruct the pose of a human body that moves in a large range outdoors. The mobile hum...

Abstract

The invention discloses an outdoor large-range human body posture reconstruction method based on mobile platforms. The method comprises the following steps: carrying out camera pose calculation and inter-camera calibration by using various sensor data of a plurality of mobile platforms, wherein each mobile platform carries a camera bound with an inertial measurement unit, an artificial vision identifier and a satellite positioning system; enabling each mobile platform to establish a human body model in real time along with the shot human body posture; and calculating an appropriate shooting angle according to the pose of the human body in the visual field, and controlling each mobile platform to move to the optimal shooting angle for shooting. The method has the beneficial effects that each camera does not need to be calibrated manually, and the operation is simple; the three-dimensional coordinates of the joint points can be calculated in real time through real-time self-calibration.As data of a plurality of sensors are combined during self-calibration, the calibration is robust.; a camera is located on each mobile platform, so that shooting is flexible; finally, the system controls the mobile platforms to move and performs shooting at a better shooting angle, so that better human body pose information can be obtained.

Description

technical field [0001] The invention relates to the fields of multi-sensor integration, camera automatic calibration, human body posture estimation, human body posture reconstruction, etc., and in particular relates to an outdoor large-scale human body posture reconstruction technology based on real-time camera automatic calibration of a mobile platform. Background technique [0002] Outdoor human body posture reconstruction plays an important role in dangerous behavior analysis, auxiliary training of athletes, battlefield environment analysis and future holographic communication. Human body posture reconstruction is the core step of dangerous behavior analysis, athlete auxiliary training and battlefield environment analysis. To obtain the behavior status of characters in the scene, the analysis of the joint point position is essential. However, the current human body posture analysis requires a complex calibration procedure, which is only for a small indoor fixed scene, and...
