Document Type and Number:
Japanese Patent JP7274856
Kind Code:
B2
Abstract:
To provide a position detection system, a position detection method, an angle detection method, and a marker that enable detection of a position, adjustment of a position, detection of an angle, and the like of a movable body with respect to a stationary body to be easily performed. Means for solving problem: A position detection system is a position detection system for detecting a position N of a movable body moving with respect to a stationary body, the position detection system including a light source provided in one of the stationary body and the movable body, an imaging unit provided in one of the stationary body and the movable body, a marker provided in the other of the stationary body and the movable body, and a position detecting unit configured to detect a position of the movable body with respect to the stationary body based on luminance of an image of the marker acquired by the imaging unit, wherein the marker includes a reflective layer, and a light control layer provided in the reflective layer, and the light control layer transmits light having an angle of incidence with respect to the main surface being within a predetermined threshold value.
