Embodiment Construction
[0017] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0018] The mid-to-long distance three-dimensional imaging system with high-resolution texture proposed by the present invention uses the principle of binocular stereo vision to obtain the three-dimensional point cloud data of the target object by two cameras on the left and right, and the large-diameter telescopic objective lens and the high-resolution CCD are used in the middle. To obtain long-distance high-resolution texture images.
[0019] Such as figure 1 As shown, the present invention has a medium and long-distance three-dimensional imaging system with high-resolution textures, including:
[0020] The first telephoto camera 1 and the second telephoto camera 2, the large-diame...

Abstract
The invention discloses a medium- and long-distance three-dimensional imaging system with high-resolution texture. The system comprises two telephoto cameras, a large-aperture telescopic objective anda high-resolution CCD, wherein the two telephoto cameras and the large-aperture telescopic objective are all installed on a rotating platform; the two telephoto cameras form a wide-baseline binocularstereo vision system to obtain three-dimensional point cloud data of a target object using the principle of binocular stereo vision; the high-resolution CCD is coupled to the rear end of the large-aperture telescopic objective to constitute a high-resolution texture image acquisition device used for shooting a high-resolution texture image of a target object at medium and long distances, and thehigh-resolution texture image acquisition device is located between the two telephoto cameras. The invention overcomes the shortcomings of obtaining a three-dimensional model of the object using the existing laser radar and the pure binocular method, which only has depth data and lacks high-resolution texture features.
Description
technical field [0001] The invention relates to the technical field of three-dimensional imaging, in particular to a mid-to-long distance three-dimensional imaging system with high-resolution textures. Background technique [0002] With the rapid development of the economy and high-end manufacturing industry, the demand for 3D measurement of large objects is increasing. In the field of aerospace, the three-dimensional shape measurement of large aerospace vehicles is very important for manufacturing quality monitoring. The three-dimensional modeling and measurement of the aircraft's full size can provide prototype data reference for digital prototype design, and can also be used as an aircraft manufacturing and flight service process. An important means of quality control. In the field of shipbuilding industry, the hull dimension detection and deformation detection have extremely high coordinate measurement accuracy requirements. [0003] In particular, the safety of medium...
