Shooting control method and system for optical motion capturing camera

Abstract

The invention provides a shooting control method and system for an optical motion capturing camera, wherein the optical motion capturing camera comprises an infrared light source. The shooting control method comprises the steps of acquiring the distance between a captured object and the infrared light source; and adjusting shooting parameters of the optical motion capturing camera according to the distance, wherein the shooting parameters comprises the exposure time and the brightness of the infrared light source. The shooting parameters of the optical motion capturing camera are automatically adjusted according to the distance between the captured object and the infrared light source of the optical motion capturing camera, the brightness of the infrared light source and the exposure time of the optical motion capturing camera can be adjusted in an adaptive manner, the infrared light source is prevented from staying at a highlight state for a long time, the heat generation amount is reduced, and the service life is prolonged. Meanwhile, a phenomenon of motion blurring generated by too long exposure time when an object which is close to the camera and high in moving speed is shot can be avoided, and the object capturing capacity of the motion capturing camera is improved.

Description

technical field [0001] Embodiments of the present invention belong to the technical field of optical motion capture cameras, and in particular relate to a shooting control method and system for optical motion capture cameras. Background technique [0002] As a technology that can realize virtual reality simulation, motion capture technology has been widely used in film and television, entertainment, medical, education, scientific research and other fields in recent years. Motion capture mainly relies on the optical motion capture camera to realize the motion capture and collection of real objects, and then process the electronic image data collected by the optical motion capture camera through a data processing terminal such as a computer. In the form of virtual data in the computer, the real object The object reverts to a virtual object. [0003] However, when a dynamic real object makes various actions, the distance between it and the optical motion capture camera will ch...

Problems solved by technology

[0004] Embodiments of the present invention provide a shooting control method and system for an optical motion capture camera, aiming to solve the problem that existing optical motion capture cameras do not have the function of adaptively adjusting shooting parameters according to distance, in order to ensure that objects at a distance can be captured It is found that the light source of the camera is always in a high-brightness state, and the exposure time is relatively long, resulting in a large amount of heat generated by the light source, which seriously reduces its service life. Too long to produce motion blur, which seriously reduces the ability to capture objects
