Embodiment Construction

[0027] figure 1 A schematic diagram of a system representing an embodiment of the invention. In this embodiment, six CMOS cameras and one TOF camera are used as the video acquisition system. Six DSP processors are used as the data processing system, the Gigabit network is used as the medium of data exchange and transmission, and the PC platform is used as the data fusion system.

[0028] figure 2 It represents the topology of the video capture system of the embodiment of the present invention. The camera array in the video capture system adopts (2*3+1) topology. Six high-resolution cameras are distributed on the four vertices and the midpoint of the long side of a rectangle, and a TOF camera is located in the center of the rectangle. Each high-resolution camera corresponds to a DSP processor in the data processing system.

[0029] Map the depth information of the TOF camera to the stereo vision system composed of all high-resolution cameras, and use it as the initial dep...

Abstract

The invention provides a three-dimensional real-time obtaining system based on camera array, comprising four parts of a video acquisition system, a signal transmission system, a data process system and a data fusion system. The video acquisition system acquires image information in scenes by using the camera array, encodes the acquired each frame of image information acco0ridng to time series, conveys it to the data process system by the signal transmission system to calculating the three-dimensional information in the scenes, and transmits it to the data fusion system by the network so as tofuse the three-dimensional data into well-determined three-dimensional data in a full scene.

Description

technical field [0001] The present invention relates to a three-dimensional acquisition technology, in particular to a camera array-based three-dimensional acquisition system capable of acquiring three-dimensional information in real time, and its application targets are application fields such as large viewing angles, large objects, and dynamic scenes. Background technique [0002] The acquisition of 3D information of the scene is a hot issue in today's vision research, but various methods are generally not perfect. First of all, there are many 3D image acquisition technologies based on single camera, dual camera and camera array. The disadvantage of these technologies is that they are not robust, and these technologies require a very large amount of computation, which is difficult even for very advanced processing units. Difficult to achieve real-time processing. [0003] TOF technology is a recently developed advanced technology for obtaining 3D information of a scene. ...
