Embodiment Construction
[0033] Such as figure 1 The shown two-primary-color grid group includes a three-row three-column grid group composed of deep and light two-primary-color grids. It is a dark base color marking layer 11 and a light base color marking layer 12. The dark base color marking layer 11 is composed of 7 hollow prism ends in a honeycomb shape, and the light base color marking layer 12 is composed of 5 inverted hollow bottomless pyramids. The bottom surface is composed of honeycomb. There are 512 kinds of patterns that can appear in the grid combination of dark and light base colors, which can be used as a coding form.
[0034] Such as figure 2 As shown, the grid is a three-dimensional structure, the two-primary-color marking layer 1 is arranged on the marking base layer 2 , and the upper surface of the two-primary-color marking layer 1 is provided with a transparent surface layer 3 .
[0035] A kind of identification method based on the two primary color square group, comprises the ...

The invention discloses a two-primary-color lattice group which comprises an m row and n column of lattice group formed by combining lattices in dark and light primary colors. The lattices comprise two-primary-color identification layers which include dark-primary-color identification layers and light-primary-color identification layers, the dark-primary-color identification layers are formed by combining a plurality of hollow prisms with honeycombed ends, and the light-primary-color identification layers are formed by combining a plurality of inverted hollow bottomless pyramids with honeycombed bottom faces. The invention further discloses a two-primary-color lattice group based identification method. Identification contrast and resolution are effectively improved, and the two-primary-color lattice group and the two-primary-color lattice group based identification method are high in accuracy and simpler to implement in computer identification systems. Further, requirements on precision of cameras are lowered, cost input is reduced, and the two-primary-color lattice group and the two-primary-color lattice group based identification method are suitable for each region.
Description
technical field [0001] The present invention relates to the field of information technology, in particular to a coding structure, and also to a coding structure based on. Background technique [0002] In recent years, with the continuous development of my country's economy, the rapid growth of the number of motor vehicles, and the rapid growth of port container business, the accuracy requirements of aerial recognition for target positioning are also getting higher and higher, and the license plate number, container number, landmark building It is becoming more and more difficult to identify objects such as objects, and there are the following technical difficulties in aerial identification: [0003] 1. The identification of objects in my country, such as license plates and container numbers, has problems such as irregular suspension of number plates, pollution, and partial occlusion. In addition, the logos of vehicle manufacturers, car body advertisements, and graffiti on car...
