Abstract

The invention discloses a feature point supplementing and extracting method used for object scanning. High-quality object three-dimensional data and object color data can be obtained from scanning and reduction of a scanning system formed by low-pixel cameras. The method comprises the following steps that (1) feature point supplementing scanning units are assembled; and one feature point supplementing lamp and at least two cameras form one feature point supplementing scanning unit; (2) a feature point supplementing scanning system is assembled; (3) all the feature point supplementing lamps are turned on to project patterns to an object to be scanned; (3) all the cameras are turned on to photograph the object to be scanned so that image information used for synthesis of the three-dimensional data and the color data of the object to be scanned is acquired; (5) the image information acquired in the step (4) is preprocessed by a data processing unit integrated on a camera control circuit board; and (6) the preprocessed image information in the step (5) is transmitted to a computer to perform reduction of the image information of the object to be scanned.

Description

technical field [0001] The invention relates to a method for restoring three-dimensional data and color data of an object, in particular to a method for restoring three-dimensional data and color data of a scanning system including multiple cameras. Background technique [0002] For the scanning system with multiple cameras, it is based on binocular recognition of the human body and is far away from the component; specifically, the system has multiple cameras, and at least two cameras will simultaneously shoot at each position of the target to be scanned Image collection; the system based on this principle has high imaging restoration efficiency and good quality; however, in order to ensure high-quality information collection, the pixels of the camera used in the current system have reached the level of a SLR camera, but the entry-level SLR camera The price of the lens ranges from 3,000 yuan to 5,000 yuan, and the cost is very high. Contents of the invention [0003] The ...
