Problems solved by technology

At present, the 3D camera process is very cumbersome. The photographer performs 3D shooting based on experience or under the guidance of professionals. The camera must be manually adjusted for different scenes. The final 3D effect needs to be modified repeatedly, and the reverse shooting rate is very high.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing:

[0013] Such as figure 1 As shown, the present invention includes a client terminal, which is used to set shooting parameters; a 3D camera device, which is used to adjust the position of the 3D camera, adjust the focus of the 3D camera, and shoot images, the number of which is two or more; The distance meter is used to measure the focal distance between the 3D camera and the subject; the 3D monitor is used to preview 3D images in real time; the storage device is used to store camera data; the numerical control module is used to control the 3D camera device to shoot images.

[0014] When in use, the photographer first sets the relevant shooting parameters of this shooting on the client terminal, and the shooting parameters are sent to the numerical control module; when the relevant equipment is started, the laser range finder on multiple 3D camera devices automatically measur...

Abstract

The invention provides an automatic locating and tracking numerical control system for a three-dimensional (3D) camera which has easiness in shooting and low re-shooting rate. The automatic locating and tracking numerical control system is characterized by comprising a client terminal for setting shooting parameters, a 3D shooting device for adjusting the position of the 3D camera to adjust a focus of the 3D camera and shoot images, a laser rang finder for measuring a focal distance between the 3D camera and a shot object, a 3D monitor for previewing the 3D images in real time, a storage device for storing camera data and a numerical control module for controlling the 3D shooting device to shoot the images. The automatic locating and tracking numerical control system has the advantages that the laser rang finder installed on the 3D shooting device is utilized to automatically measure the focal distance, the numerical control module is utilized to work out the optimal distance and the optimal included angle between the 3D cameras by applying an eyeball three-dimensional optics principle, the 3D shooting device is utilized to perform self-adjustment and shoot the images, and manual control and intervene are not needed.

Description

technical field [0001] The invention belongs to the technical field of numerical control, in particular to a numerical control system for automatic positioning and tracking of a 3D stereo camera. Background technique [0002] With the rapid development of digital film production technology and projection technology, digital high-definition 2K and 4K movies have gradually become mainstream, especially with the increase in the number of Imax projection halls, the requirements for the picture quality of movies are getting higher and higher, and the demand for 3D movies is also increasing. bigger and bigger. 3D camera and 3D rendering output are two important links in the production of 3D movies. Their technical requirements are relatively high, and it is difficult for ordinary movie manufacturers to complete them. Therefore, the source of movies is very scarce. Most of the 3D movies in theaters are monopolized by imported blockbusters. At present, the 3D camera process is very...
