Abstract

The invention provides a combined type measurement and three-dimensional reconstruction method combing a Kinect device and an articulated arm measuring instrument. Firstly, quickly obtaining point cloud data of an object through the Kinect, performing secondary measuring on feature information which cannot be obtained by the Kinect and on features with high accuracy requirements through the articulated arm, completing fusion of different data source information by means of point cloud registration technology, and reconstructing a three-dimensional model of the object. According to the combined type measurement and three-dimensional reconstruction method combing the Kinect device and the articulated arm measuring instrument, non-contact measurement and contact type measurement are combined together, not only the problem of low accuracy of the non-contact measurement can be solved, but also point cloud data with lost boundaries and concave holes and the like can be effectively repaired, meanwhile, measuring efficiency can be improved, and novel technology and means are provided for data acquisition.

Description

technical field [0001] The invention relates to a compound measurement and three-dimensional reconstruction method combining Kinect and an articulated arm. Background technique [0002] As an important branch of computer vision technology, 3D reconstruction technology has always been one of the hottest research directions in the field of computer vision. It belongs to a multidisciplinary research field and is an important application of computer graphics and image processing in engineering. [0003] The measuring equipment converts the surface shape of the object into coordinate points in geometric space through a specific method, so as to obtain the data required for reverse modeling. The data acquisition method based on contact measurement has high accuracy and reliability, and can accurately measure the basic geometric shapes of objects, such as surfaces, circles, cylinders, cones, spheres, etc., but the data acquisition efficiency is low. The data acquisition method b...
