Abstract

A method and apparatus for obtaining a video action based on an identification point are disclosed. The method comprises the following steps of: acquiring calibration information of a camera, wherein,the calibration information of the camera at least comprises a lens focal length, an imaging center, a tilt factor and distortion parameters; acquiring video information captured by a camera, whereinthe video information includes at least an encoded pattern of identification points arranged on a target object for marking a moving state of the target object; obtaining target information of an identification point, wherein the target information comprises at least: a coding pattern of the identification point and spatial structure information of the coding pattern; according to the calibrationinformation and the target information of the identification point, the three-dimensional reconstruction of the video information being carried out, and the spatial posture change of the identification point in the camera coordinate system being obtained. The invention solves the problems that the motion capture system in the related art cannot simultaneously give consideration to the simple structure, the convenient operation and the accurate motion reconstruction.

Description

technical field [0001] The present application relates to the field of computer graphics and animation, in particular, to a method and device for acquiring video actions based on marker points. Background technique [0002] Traditional motion capture systems include electromagnetic, mechanical, and optical, among which optical is the most mature and commonly used capture system in recent years. There are a wide range of applications in production and other fields. [0003] The characteristic of this type of system is to use special markers to mark the target, and to accurately measure the movement information of the target through a multi-camera array based on the principle of stereo vision. It has the advantages of high precision and accurate motion reconstruction. However, due to the large and complex system and the large amount of installation work, it can usually only be used in a fixed studio, and has high requirements for ambient light. The site cannot be directly exp...
