AI Technical Summary

Technical Problem

Existing object position detection methods, such as those using cameras placed directly above workpieces, struggle to accurately detect the position of objects in the plane direction due to distortion and lack of consideration for the height of the object.

Method used

An object position detection method that involves photographing the target object from an imaging device positioned diagonally above, correcting image distortion, and determining the object's position in the plane direction by calculating the intersection of the image pickup axis and a plane offset by the object's height dimension.

Benefits of technology

This method allows for high-accuracy detection of object positions in the plane direction without complex processing, effectively addressing the limitations of previous methods by incorporating height considerations and distortion correction.

Abstract

[Problem] To detect the position of a target object, such as a workpiece, with high accuracy. [Solution] This industrial machine comprises: an imaging control unit that causes an imaging device to capture an image of a target object, the imaging device being provided at a position at which the imaging axis of the imaging device is not perpendicular to a placement surface on which the target object is placed; and a detection unit that detects a position of the target object in the planar direction on the basis of the image acquired by imaging the target object and the dimensions of the target object in the height direction acquired beforehand.
