Description
Technical Field
The utility model relates to a detection device especially relates to a surface vestige detection device.
Background
Three-dimensional reconstruction is a research hotspot of computer vision, and refers to a process of acquiring a data image of a scene object through a camera and auxiliary equipment and reconstructing three-dimensional information of the object in a real environment according to a single-view image or a multi-view image. The three-dimensional reconstruction has wide application fields, including object three-dimensional model establishment, 3D printing, three-dimensional display, three-dimensional distance measurement, unmanned aerial vehicle obstacle avoidance navigation, augmented reality and the like. Equipment based on visual three-dimensional reconstruction methods such as laser line scanning, binocular stereo vision, motion recovery structures and the like has been applied to the market.
Photometric stereo is a technology for recovering three-dimensional stereo based on the change of light intensity reflected from a surface. Compared with the technologies of binocular, motion recovery structure and the like, the photometric stereo can reconstruct surface fine features and recover more details, and the method has the advantages of high precision and high resolution. However, the photometric stereo technique needs to capture a plurality of images under different lighting conditions at a fixed single viewing angle, and then obtain three-dimensional information according to the light intensity variation of an object. Thus, photometric stereo devices require the acquisition device to be stationary during the image acquisition phase, and multiple light sources make the device bulky. This makes photometric stereo difficult to apply to consumer-grade portable devices, or mobile devices, nor to large-scale scanning imaging. In summary, the photometric stereo technique is limited by the requirement of multi-illumination imaging, and the three-dimensional reconstruction of moving objects has higher requirement, so the existing photometric stereo technique cannot be applied to the three-dimensional reconstruction of moving objects, and a moving three-dimensional reconstruction method based on multi-view photometric stereo is required to be provided.
Therefore, it is necessary to develop a surface trace detection device which is simple in operation, and the same technical solution as the present invention is not found through searching.
