Self-rotary scaffolding convergent multi-view three-dimensional data collection system and method

Abstract

The invention belongs to the technical field of three-dimensional image collection and relates to a self-rotary scaffolding convergent multi-view three-dimensional data collection system, comprising a primary camera, a secondary camera, a laser distance measuring module, a main controller and a camera support, wherein the camera support comprises a supporting tray, a primary beam, a plurality of secondary beams and a plurality of electronic rotary shafts; the middle part of the primary beam is fixed on the supporting tray; the corresponding ends of the adjacent upper and lower secondary beams are connected through the electronic rotary shafts by taking the primary beam as the centre; and the primary controller controls the convergence and focus synchronization of the plurality of cameras according to distance signals output by the laser distance measuring module. The invention also provides a convergent multi-view three-dimensional data collection method which is realized by using the system. The self-rotary scaffolding convergent multi-view three-dimensional data collection system and method disclosed by the invention can obtain parallax images of vivid represented display effects of three dimensional scenes and realize synchronized convergent three-dimensional data collection.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional image acquisition, and in particular relates to a convergent multi-viewpoint three-dimensional data acquisition system. Background technique [0002] Autostereoscopic display is one of the most important stereoscopic display methods at present. It uses two eyes to watch a plane image with parallax to form a stereoscopic image with a sense of depth in the brain. Images with parallax can be obtained by using multiple cameras to capture the actual 3D scene. There are two ways to arrange the camera array: the converging camera array method and the parallel phase array method. In the parallel camera array method, the optical axes of the cameras are parallel to each other, and the object planes coincide. The entire three-dimensional scene has only negative horizontal parallax and no positive horizontal parallax. On the autostereoscopic display, only the three-dimensional scene that protrudes ...
