AI Technical Summary

Technical Problem

Existing 3D scanners have difficulty accurately detecting the position of surveying spikes embedded in the ground due to their small size and lack of irregularities, making it challenging to distinguish the boundary between the spike and the ground.

Method used

A 3D scanner measurement target equipped with legs, a slider, a support for a marking device, a tilt adjustment mechanism, and a target piece that can be accurately positioned using a 3D scanner to detect the surveying spike's position.

Benefits of technology

Enables precise detection of the surveying spike's position by aligning the target piece directly above the spike, allowing for accurate measurement in point cloud data without directly measuring the embedded spike.

Abstract

To provide a 3D scanner measurement target for enabling the position of a surveying tack installed on the ground to be accurately detected by a 3D scanner.SOLUTION: A 3D scanner measurement target 1A comprises: legs 3 that are placed on a ground surface 100; a slider 57 that is supported to the legs 3 so as to be movable to the legs 3 in an orthogonal direction that is orthogonal to the vertical direction of the legs 3; a support 30A for supporting a marking instrument 11A that sends out a marker M toward the ground surface 100; an inclination adjustment mechanism 56 that is constituted so as to be capable of adjusting the attitude of the support 30A relative to the horizontal plane and constituted so as to be capable of moving integrally with the slider 57 in the orthogonal direction; and a target piece 12c that is held to the support 30A and is detected by a 3D scanner 200.SELECTED DRAWING: Figure 10
