The group of inventions relates to measuring technology, in particular to methods for inspection of the shape of hard-to-reach parts, and can be used in power engineering, transport, mechanical engineering and other fields of technology to measure the geometric parameters of a part. The technical result of the invention as claimed is to increase the accuracy, reliability and performance of measurements related to determining the shape and defects of parts installed in cavities, as well as the shape of the internal cavities of products and surface discontinuities. The method for controlling the shape of hard-to-reach parts, including the stages of delivery inside the controlling equipment of the executive part of the control system equipped with a miniature stereo camera, for navigation across the path of which white light illumination is used, the white light illumination is transmitted through an optical fiber, after leaving which the given indicatrix of intensity is formed by means of the first lens. This is followed by the stage of turning off or dimming the white light, followed by turning on the laser, which, by means of an optical fiber transmitting a laser stream passing through the second lens, forms a beam of rays, which, passing through a diffraction optical element, forms an image with small laser spots of intensity on the hard-to-reach surface of the part to obtain a stereo image of the hard-to-reach surface of the part. A three-dimensional hard-to-reach surface is restored, while laser intensity spots on a pair of flat images are used to automatically identify the same points of object on stereo images with a given degree of confidence. The inspection system consists of a miniature digital camera that forms a stereo image of the object under control, a white light illumination unit, a laser illuminator operating in pulsed or continuous mode, a handle placed on the articulation control panel, a PC for processing and displaying information, articulation cables, two lenses, DOE, a laser fiber, lighting fiber, power line and a video signal transmission line.

This invention applies dynamic weighting between a point-to-plane and point-to-edge metric on a per-edge basis in an acquired image using a vision system. This allows an applied ICP technique to be significantly more robust to a variety of object geometries and/or occlusions. A system and method herein provides an energy function that is minimized to generate candidate 3D poses for use in alignment of runtime 3D image data of an object with model 3D image data. Since normals are much more accurate than edges, the use of normal is desirable when possible. However, in some use cases, such as a plane, edges provide information in relative directions the normals do not. Hence the system and method defines a “normal information matrix”, which represents the directions in which sufficient information is present. Performing (e.g.) a principal component analysis (PCA) on this matrix provides a basis for the available information.
