Embodiment Construction

[0041] Such as figure 2 As shown, the present invention adopts two digital cameras, wherein 1 and 7 are respectively the optical systems of the left and right digital cameras, 2 and 8 are respectively the exposure control circuits of the left and right digital cameras, 3 and 9 are respectively the imaging devices of the left and right digital cameras, and 4 10 and 10 respectively represent memory, 5 represents a computer, and 6 represents a controller.

[0042] Such as image 3 As shown, the relative position parameters of the image sensor: the origin of the object-space coordinate system is not always selected at the projection center of the image sensor (the origin of the object-space coordinate system does not coincide with the origin of the image space coordinate system), and the image space coordinate system cannot be guaranteed Each axis is parallel to each axis of the object space coordinate system. Therefore, the orientation of the image space coordinate system (proj...

Abstract

This invention discloses a kind of digitized measure and reconstruction method and equipment that can capture the three-dimensional space object image, which based on computer stereo vision, computer graphics and optical imaging theory. By at least two image sensors that with the set distance and known parameters, it images the same space object and gets at least two opposite pictures, which are transferred to the computer. Then it confirms the three-dimensional coordinates at any target point based on the optical imaging theory. According to the three-dimensional coordinates of multiple target points, it determines the geometric parameter of space object by the geometrical relationship and finishes the measurement of space object. According to the geometric parameter of measured space object, it can draw interactively with the existing drawing software, or build the three-dimensional digital model directly.

Description

technical field [0001] The invention belongs to the digital processing technology of object imaging, and specifically relates to a method of directly measuring the three-dimensional coordinates required to describe the object after the object is imaged according to the principle of optical imaging, so as to establish a three-dimensional model of the measured object and realize various on-site three-dimensional coordinates. digital technology. Background technique [0002] With the development of science and technology, information and information technology has become a major breakthrough in science and technology that has greatly changed human society. From the concept of digital earth, it can be understood that digital earth is "a unified digital reproduction and understanding of the real earth and its related phenomena", in which a large amount of digital three-dimensional space information that truly reflects different scale spaces (scenes) is an important part of digita...
