Abstract
Provided is a marker detection apparatus able to easily detect the position of a marker and a robot teaching system using the same. A marker detection apparatus includes: a three-dimensional plane detection unit that detects a three-dimensional plane serving as a plane in a three-dimensional space on a basis of point group data acquired by a 3D camera; a two-dimensional plane image generation unit that projects point group data constituting the detected three-dimensional plane in a perpendicular direction based on the three-dimensional plane, thereby generating a two-dimensional plane image; a marker detection unit that detects a marker from the generated two-dimensional plane image; and a marker position calculation unit that, for the detected marker included in the two-dimensional plane image, calculates three-dimensional coordinates on the three-dimensional plane.
