Abstract: A position detection system includes: a plurality of distance detection apparatuses that generate distance data indicating distances to a plurality of positions on the object by detecting light reflected by the object in a predetermined three-dimensional space; an object identification part that identifies the object included in one or more pieces of distance data among a plurality of pieces of the distance data generated by the plurality of distance detection apparatuses; and a position identification part that identifies a position of the object in the three-dimensional space on the basis of (i) a position in the three-dimensional space of the distance detection apparatus that generated the distance data with which the object identification part identified the object and (ii) a position of the object in the distance data.

Abstract: A measurement apparatus includes a sensor that measures a workpiece, a multi-axis robot that moves the sensor in a three-dimensional space, a position determination part that determines i) a plurality of measurement positions that are positions along a normal direction at each of a plurality of positions to be measured on the workpiece and ii) a direction of the sensor at each of the plurality of measurement positions on the basis of at least either design data or captured image data indicating the geometry of the workpiece, a moving control part that sequentially moves the sensor to the plurality of measurement positions by controlling the robot, and a measurement control part that outputs measured data indicating a result that the sensor measured at each of the plurality of measurement positions in association with the plurality of positions to be measured.

Abstract: A nondestructive measurement apparatus includes a casing including a grip portion capable of being held in hand and a measurement portion having a ring shaped abutting portion to be abutted to a measurement target such as fruit or vegetable; a light source group including a plurality of light sources arranged to be separated in a circumferential direction in an interior thereof; a ring lens arranged in a ring shape smaller than the abutting portion at an inner portion of the abutting portion, for emitting lights from the light source group to an external of the casing in a ring shape; and a light guide member having one end surface exposed to an inner side of the ring lens and another end surface positioned in the interior of the casing, for emitting lights incident from the one end surface to the external from the another end surface.
