Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] Such as Figure 1-3 As shown, the present invention includes a support base 20 and a three-dimensional target body 10 installed on the support base 20, and the shape of the three-dimensional target body 10 is a cylinder. The cylindrical surface of the three-dimensional target body 10 is coated with colored ring-shaped stripe layers 11 of different colors, and the colored ring-shaped stripe layer 11 is oil-soluble glossy paint of various colors, thereby forming a visual system that can be accurately viewed from different horizontal angles. Identify and track 3D targets. The interior of the three-dimensional target body 10 is a hollow cylindrical structure, and the material of the three-dimensional target body 10 is duralumin, which reduces weight and materials. In order to realize installation and fixation, a through hole I is left at the center of th...

It includes a support seat and a three-dimensional target body installed on the support seat. The shape of the three-dimensional target body is a cylinder, and the cylindrical surface of the three-dimensional target body is coated with a colored ring-shaped stripe layer. Color oil soluble gloss varnish. The invention has the advantages of convenient installation and maintenance, identification robustness, high stability and high guiding precision.

Description

technical field [0001] The invention relates to the technical field of vision guidance, in particular to a three-dimensional target used in a vision guidance system. Background technique [0002] Using the method of installing a guide target on an object (such as a vehicle, etc.), the target is identified and tracked by a vision system to achieve rapid and accurate identification and tracking of the object. Typically, targets used in vision systems are mainly classified into one-dimensional, two-dimensional and three-dimensional structures. Three-dimensional targets generally include square targets and spherical targets, but square targets have the problem of misalignment of central axes after perspective projection transformation in the vision system, and cannot achieve accurate alignment and tracking of objects, while spherical targets avoid the above-mentioned problems of square targets , but its manufacturing process and cost are relatively high, and its installation is...
