Three-dimensional imaging method based on multi-camera array

Abstract

The invention relates to three-dimensional imaging, in particular to a three-dimensional imaging method based on a multi-camera array, which comprises the following steps of calibrating each camera, keeping the position of the camera unchanged, placing a calibration plate at the center of an overlapped view field of two adjacent cameras, and identifying an image of the calibration plate; sequentially obtaining external parameters of adjacent cameras by using the identified calibration board image, sending prompt information to a control node when the cameras finish acquisition preparation, disconnecting a control thread corresponding to the cameras by the control node, and sending synchronization information to a synchronization node by the control node after each camera sends the prompt information to the control node, enabling the synchronization node to start control threads corresponding to the cameras at the same time, and call collected images of the cameras at the same time; according to the technical scheme provided by the invention, the defects in the prior art that better consistency control cannot be carried out on the camera array and better splicing fusion processing cannot be carried out on the acquired image can be effectively overcome.

Description

technical field [0001] The invention relates to three-dimensional imaging, in particular to a three-dimensional imaging method based on a multi-camera array. Background technique [0002] At present, the existing 3D imaging technology is mainly binocular stereo vision imaging technology, which requires a pair of cameras to collect scene images at the same time, compare the left and right images through a matching algorithm, and calculate the disparity information. Based on the disparity information and the principle of triangulation, the final 3D imaging . [0003] However, the matching algorithm involved in the current binocular stereo vision system is very complex, so a powerful computing unit is required, the cost is high, and it is difficult to miniaturize. Consistent real-time. The stereo matching part of the binocular system has relatively high requirements for the imaging scene. Depth cameras are usually used. Generally speaking, the points on the color image and th...
