Sub-eye optimal arrangement method of compound eye system based on three-dimensional detection

Abstract

The invention discloses a sub-eye optimal arrangement method of a compound eye system based on three-dimensional detection. A regular polyhedron is subjected to subdivision with the frequency being v,subdivided vertexes are used as sub-eye centers for distribution structure design, and the method has the main advantages that subdivision with the frequency being v subdivides each face of the regular icosahedron for v times, and the sub-eye arrangement uniformity is greatly improved compared with an original hexagonal structure; the compound eyeball shell designed and processed by using the regular polyhedron subdivision method can realize more dense arrangement. Manufacturing is convenient, and subsequent processing such as image recognition, splicing and multi-channel fusion is also facilitated. The defect that regular hexagons are seriously deformed due to the fact that hexagons cannot be arranged on spherical surfaces in a sealed connection mode in a traditional arrangement method is overcome.

Description

technical field [0001] The present invention relates to the optimized design field of the sub-eye distribution of the new electronic compound eye system, in particular to an optimized arrangement structure of the sub-eyes which can narrow the distance between the sub-eyes and improve the uniformity of the imaging spots, that is, the sub-eyes of the compound eye system based on three-dimensional detection. Eye optimization arrangement method. Background technique [0002] In the compound eye system, in order to ensure that the spatial luminous point can be detected by multiple sub-eyes at the same time, the sub-eyes need to be arranged relatively closely, so various sub-eye arrangements have been proposed. The traditional scheme is to arrange the sub-eyes in a hexagonal structure, that is, there are 6 closely adjacent sub-eyes around each sub-eye, and these 7 sub-eyes can usually detect a luminous point in space at the same time, thus forming a Based on the basic unit of com...

Problems solved by technology

[0004] In order to solve the problem that the sub-eyes in the compound eye system are farther and farther away from the center, the difference between the sub-eyes becomes larger and the distribution becomes more and more uneven. This patent proposes a sub-eye optimization method based on three-dimensional detection of the compound eye system For the distribution structure of the subdivision of the regular polyhedron, each face of the polyhedron is directly divided into smaller regular polygons, and then these bisection points and intersection points of the bisector lines are projected onto the regular polyhedron along the radial direction The vertices are obtained on the circumscribed sphere, so the uniformity of the vertex division is guaranteed, and the vertices obtained by the subdivision method are used as the positions of each sub-eye, so that the distribution of the sub-eyes on the spherical surface is more uniform
