The invention relates to a system and a method for object surface reconstruction. The system comprises an illumination component, an image sensor, a controller and a data processing unit, wherein the illumination component comprises a light source and a mirror surface reflecting device, and is used for forming a linear array structural light pattern in a target area; the image sensor is used for gradual exposure to shoot a projective image of the structural light pattern of at least a part of area in the target area; the controller is used for controlling an exposure region of the image sensor to be synchronized with a structural light projective region of the mirror surface reflecting device; and the data processing unit is used for receiving and obtaining the projective image and a shift value of the structural light pattern in a pre-shot standard image in real time, and is used for calculating three-dimensional cloud data of the object in the target area. By the adoption of the system and the method, a preset structural light pattern is projected in the target area according to the requirement, the synchronized exposure of the image sensor is controlled to shoot the projective image of at least a part of area in the target area, the projective image is compared with the standard image, the three-dimensional depth data of the object in the target area is calculated, and thus real-time moving data of a moving object is obtained.
Description
[0001] This application is a divisional application of an invention patent application with the filing date of January 27, 2011, the application number of 201110029945.2, and the title of "A System and Method for Object Surface Reconstruction". technical field [0002] The present invention relates to a three-dimensional image reconstruction technology, and more specifically, to a system and method for object surface reconstruction. Background technique [0003] Point cloud data is the points obtained by direct sampling of the surface of the object by using the 3D scanning equipment. These points are the initial and most direct representation of the surface of the 3D model. By analyzing the point cloud data, the geometric surface of the model can be reconstructed. [0004] There are many ways to acquire object point clouds. Common methods include using structured light image information to acquire point cloud data, and binocular visible light image information to acquire dat...
