Portable four-camera three-dimensional photographic measurement system and method

Abstract

The invention relates to a portable four-camera three-dimensional photographic measurement system and method. According to the system, four cameras can synchronously shoot images, and equipment parameters which are set in advance can be kept; a three-dimensional image can be measured automatically on a computer, so that physical geometric information such as positions, sizes and shapes of objectsand scenes and physical property information such as the materials and textures of the objects can be obtained; and on the basis of the information, a three-dimensional model can be automatically constructed or the volume, the area and the like of a three-dimensional object can be analyzed. The system is portable and can be carried and operated by a user conveniently, and can be flexibly applied to measurement and three-dimensional reconstruction of a plurality of scenes.

Description

technical field

[0001] The invention relates to the technical field of photography, in particular to a portable four-eye stereoscopic photogrammetry system and a corresponding method. 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. The digitized three-dimensional space data of various scenes and objects is one of the important foundations of information. An important part of it is the acquisition of digital three-dimensional space data, and its key point is how to carry out this process effectively, quickly, comprehensively and correctly.

[0003] Traditional measurement and scene 3D digitization methods mainly rely on equipment such as meter rulers, range finders, total stations, etc., which can complete single-dimensional measurement on site. The disadvantages of this measurement method are: low measurement...

Examples

Embodiment Construction

[0017] The prerequisites for four-eye stereo photogrammetry are: ①. The four cameras that make up the four-eye must be photographed synchronously to prevent parameter failure caused by the movement of the camera itself or dynamic scenes and object movements; ②. The parameters of the four-eye stereo system are known, and has remained constant during the measurement. In addition, considering the need for portability in actual work, the equipment is required to be portable, flexible in operation, and must be able to provide necessary protection to the core equipment. The portable four-eye three-dimensional photogrammetry system of the present invention provides an image-based non-contact measurement device, which can perform synchronous photography and imaging of four cameras on a measured object. Then, it can be measured on the image to obtain physical geometric information such as three-dimensional coordinates, size and shape required to describe the object, and physical attrib...
