Description

Technical field: [0001] The invention relates to a three-dimensional video simulation platform, in particular to a three-dimensional video simulation production platform and a production method based on motion capture. Background technique: [0002] Motion Capture (Motion Capture) refers to recording the movement trajectory of a moving body in three-dimensional space through a sensing device, converting it into abstract motion data, and then driving the virtual moving body to move according to these data. In order to achieve the purpose of moving and controlling the virtual moving body, it is usually necessary to edit and synthesize the motion capture data. [0003] At present, motion capture mainly includes mechanical, electromagnetic, and acoustic types. Among them, mechanical motion capture: relies on mechanical devices to track and measure motion. A typical system consists of multiple joints and rigid links. An angle sensor is installed in the rotatable joint, which can...

Problems solved by technology

Its disadvantages are: inconvenient to use; specific purpose of use; mechanical structure greatly hinders and restricts movement

Its disadvantages are: strict requirements on the environment, no metal objects near the site, otherwise it will cause electromagnetic field distortion and affect the accuracy; the cable has a large restriction on the movement, which is not suitable for more violent sports; the sampling rate is low, for some high-speed sports, Such as sports, the sampling speed cannot meet the requirements

Its disadvantages are: there is a large delay and lag in the capture of motion, and the accuracy is poor; there must be no shelter between the sound source and the receiver, and it is greatly disturbed by noise, etc., and the system expansion is difficult; due to the speed of sound waves in the air and the air pressure, humidity, etc. , temperature, and corresponding compensation must be made in the algorithm
