| Abstract: | To achieve the live-action and virtual shooting system, an entity shooting bracket based on embedded controller is designed. In the light of the problem of ultra-high price of shooting robot in foreign countries, a low cost, easy to use live-action and virtual shooting system is designed, the computer end plug, communication interface, embedded controller, motion control support are completed. By practical application, the accuracy and resolution of virtual camera pose reach 30 frames per second, the rotation direction and speed of live-action camera remain completely synchronized with the virtual camera. After the live-action and virtual system synchronize the motion path of virtual camera and camera, the accurate video content synthesis effect is obtained. |
