AI Technical Summary

Technical Problem

Existing object detection systems face a decrease in detection accuracy due to objects with undefined orientations, as marks on these objects can be obscured by blind spots from the camera, leading to incomplete image capture.

Method used

A marked object design featuring non-parallel first and second marks on distinct holding portions, each with a unique identification mark, allowing for accurate detection through a marked object detection system that includes a camera unit and calculation unit to process these marks.

Benefits of technology

Enhances detection accuracy by ensuring marks are observable from multiple angles, enabling precise determination of object position and orientation even when partially obscured.

Abstract

This suppresses the decrease in detection accuracy for marked objects whose orientation is not fixed. [Solution] The marked object 5 comprises an object 6, a first mark 51 provided on a first holding portion 8 of the object, and a second mark 52 provided on a second holding portion 9 of the object. The normal direction ND1 of the first holding portion 8 and the normal direction ND2 of the second holding portion 9 are non-parallel.
