Abstract

The invention discloses a method for adjusting the field of view overlap rate of a multi-eye camera acquisition system, which comprises the following steps: arranging S brackets at equal intervals on an arc with the target object as the center and the working distance D as the radius, wherein the first The arc angle between the root bracket and the last bracket is α; N cameras are vertically and equally spaced on each bracket; adjust the value of the working distance D and the value of the angle α, after each adjustment, Calculate the vertical field of view overlap rate of two adjacent cameras up and down on the same support, and the horizontal field of view overlap rate of two adjacent cameras on the same height on two adjacent supports; the vertical view field overlap rate and the horizontal field of view overlap rate are both If it is greater than 80%, then the adjustment of D value and α value of this time is qualified. The invention guarantees the image reconstruction quality of the multi-eye camera acquisition system.

Description

technical field [0001] The invention relates to the technical field of three-dimensional image reconstruction, in particular to a method for adjusting the field of view overlap rate of a multi-eye camera acquisition system. Background technique [0002] A large number of industrial cameras are installed in the dense multi-camera acquisition system. The system imports the images collected by each camera into the 3D reconstruction software for 3D graphics reconstruction, and the quality of graphic reconstruction is related to the overlap rate of adjacent camera fields of view. Camera field of view overlap rate includes vertical field of view overlap rate and horizontal field of view overlap rate, the larger the field of view overlap rate, the higher the quality of image reconstruction. [0003] The existing multi-camera acquisition system does not adjust the overlap rate of the camera's field of view during the installation process, so the reconstruction quality of its 3D mode...
