Abstract

The invention provides a multi-ocular camera system, a device and a synchronization method. The synchronization method comprises the following steps: a hardware signal generating device generates a synchronization signal, and simultaneously transmits the synchronization signal to a plurality of camera units through cables; the plurality of camera units receive the synchronization signal transmitted by the hardware signal generating device, and each camera unit is triggered by the synchronization signal to shoot a synchronous two-dimensional image; and a synchronous image matching device acquires the synchronous two-dimensional images shot by each camera unit, and synchronously matches the plurality of acquired synchronous two-dimensional images. According to the technical scheme provided by the invention, the hardware signal generating device transmits the generated synchronization signal to the plurality of camera units through the cables to shoot the synchronous two-dimensional images, and matching of the synchronous two-dimensional images is realized through the synchronous image matching device. The transmission speed of signal transmission through the cables is close to the speed of light, and time is hardly consumed, so that accurate synchronization of a plurality of camera units in a large-baseline multi-ocular camera system can be realized through transmission of the synchronization signal via the cables.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a multi-eye camera system, device and synchronization method. Background technique [0002] With the rapid development of information technology, people have more and more needs for 3D models and related needs, and the multi-camera system is an important means to realize 3D models. A multi-eye camera system refers to a camera system composed of multiple imaging camera units, each imaging camera unit is fixed at a certain distance and angle. Two-dimensional images are collected synchronously by multiple imaging camera units, and multiple two-dimensional images collected at the same time are combined into three-dimensional stereo image data through a stereo vision algorithm for computer vision processing. [0003] The baseline of a multi-camera system refers to the distance between camera units. The size of the baseline affects the distance of the target in the three-dimensional ima...
