Problems solved by technology

Since the development of 3D reconstruction technology, there have been many methods. However, it can be found that each method has its inapplicability, which will bring a lot of trouble in practical application and seriously limit the application range of a certain reconstruction method.
Therefore, it is urgent to propose a 3D modeling method with general applicability, but it is quite difficult

Abstract

The invention provides a three-dimensional reconstruction system and reconstruction method based on PAL cameras. The reconstruction system comprises two industrial cameras respectively provided with a PAL lens, the two PAL lenses are arranged in a perpendicular manner, and the two industrial cameras are connected with a computer through USB data wires. The three-dimensional reconstruction method comprises the following steps of: arranging the two industrial cameras respectively provided with one PAL lens in the perpendicular manner and connecting the two industrial cameras with the computer; b, using the industrial cameras to collect image data, and transmitting the image data to the computer; c, carrying out processing and calculation on the image data, and obtaining optical characteristic relations of the cameras; d, correcting image distortion based on the optical characteristic relations of the cameras; e, utilizing a dynamic programming algorithm to match two images obtained by shooting; f, converting points of a panoramic image in a cylindrical coordinate system into points in a three-dimensional coordinate system; and g, drawing a three-dimensional scene to be reconstructed. The three-dimensional reconstruction system and reconstruction method have the advantages that the structure is simple, the operation speed is high, and the system and the method are applicable to the reconstruction of a large-range scene.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a three-dimensional reconstruction method based on a PAL camera and a reconstruction system thereof. Background technique [0002] 3D reconstruction refers to the establishment of a mathematical model suitable for computer representation and processing of 3D objects. It is the basis for processing, operating and analyzing the nature of 3D objects in a computer environment, and is also a key technology for establishing virtual reality in computers. [0003] As one of the research directions of computer vision, 3D reconstruction is inspired by the human eye. First, digital sensing equipment is used to shoot objects, and then computers are used to process the captured images, finally to obtain the 3D information of objects. Use cameras (single or multiple) to shoot an object from different angles, and reconstruct the 3D model of the object by processing the captured images, which is ...
