[0030] This solution does not limit the structures of the first positioning component and the second positioning component, and the specific structures can be determined according to actual conditions.

[0031] Inside the formed three-dimensional frame structure 100 , since its size corresponds to the bionic target, a coordinate system can be established inside, and the positioning of the sensor can be determined by the position on the coordinate system.

[0032] In this solution, a three-axis coordinate system is formed by arranging a positioning unit inside the three-dimensional frame structure 100 and cooperating with the first bracket 110, the second bracket 120, the third bracket 130 and the fourth bracket 140 on the side of the three-dimensional frame structure 100.
