Abstract

The invention provides a high-precision 3D recognition calculation method and system. The method comprises the steps that a D point is preset as a detection reference point at a light transmitting end, a first reference plane is set through the D point, and a reference graph is set in the first reference plane; the light transmitting end transmits a light beam to the identified end at a certain angle, the projection point of the point D is a point D', a second reference plane is established with the D' point, the second reference plane is parallel to the first reference plane, SDD' is obtained, the SDD' is the distance from the D point to the D' point, a projection graph obtained by projecting the reference graph to the second reference plane is a detection graph, and the detection graph is collected. The detection reference point is added, a first reference plane is set according to the detection reference point, a reference graph is arranged in the first reference plane, so that a second reference plane parallel to the first reference plane is established at a projection point of the reference point at the identified end, a detection graph is obtained, the detection graphs identified in different areas are spliced, surface concave-convex in a small range is identified more finely, and the identification accuracy of a micro area is effectively improved.

Description

technical field [0001] The invention relates to the field of electronics, in particular to a high-precision 3D recognition calculation method and system. Background technique [0002] With the development of AR technology, 3D recognition technology is gradually applied to people's lives. At present, 3D recognition has the problems of difficult chip production, complex software algorithm forming, and inaccurate recognition rate, and poor recognition of unevenness in a small range. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior art, the present invention provides a high-precision 3D recognition calculation method and system to solve the above-mentioned technical problems. [0004] The high-precision 3D recognition calculation method provided by the present invention includes: [0005] The light emitting end pre-sets point D as the detection reference point, sets the first reference plane with the D point, and sets a reference fi...
