Embodiment Construction

[0025] Such as figure 1 As shown, a device for small-scale scene reconstruction based on dual cameras includes a controllable turntable 3, a camera frame and built-in two cameras 1, 2, a console 4, an image memory 5 and a processor 6, the two cameras 1, 2 are relatively placed up and down on the turntable 3, and the turntable 3 is a controllable high-precision turntable. The console 4 can control the shooting of images, the images are transmitted to the image storage 5 through the network for storage, and provided to the processor 6 for subsequent operations. Console 4 and processor 6 may physically be one machine.

[0026] figure 2 Shown is a schematic block diagram of the structure of the method of the present invention. As shown in the figure, the method for reconstructing a small scene based on the above-mentioned device includes the following steps:

[0027] (1) Camera calibration: Use reference objects (such as calibration checkerboards) to calibrate the two cameras,...

Abstract

The invention relates to a small scene three-dimension rebuild method, based on two cameras, which comprises two cameras, a rotating platform for mounting cameras, and the processes that demarcating cameras, shooting image, matching image and assembling three-dimension model on the small scene. The invention also discloses a relative device, which comprises a controllable rotating platform, a camera support on the rotating platform and internal camera, console, image memory and processor, while two cameras are up-to-down opposite arranged, the console controls the rotating platform and two cameras to shoot image, and the image via network is transmitted to the image memory to be stored, and the processor will process image match and three-dimension model assemble. The invention reduces the match between two images into two relative polar lines, to improve the efficiency and accuracy, with simple process and operation. And it separates the prophase image shooting and following treatment, to simplify the prophase operation.

Description

technical field [0001] The invention relates to a three-dimensional reconstruction method suitable for small scenes and a corresponding device thereof. Background technique [0002] The current traditional archaeological excavation method is to destroy the archaeological site during and after the archaeological work, so that the subsequent archaeological research work cannot directly observe the archaeological excavation site; because there is no digital information, the research of the archaeological site can only be done by going to the field The method of viewing is carried out, but geographical restrictions often bring great difficulties to this research method. [0003] In recent years, with the rapid development of computer technology, especially virtual reality, computer vision, graphics and other technologies, digital archeology has attracted more and more attention from all over the world. As an important research direction of digital archaeology, the 3D reconstruc...
