Abstract: A coordinate measuring apparatus includes a measuring part that measures a workpiece, three or more access points that are provided at positions away from the measuring part and perform wireless communication with the measuring part using radio waves, a laser tracker that irradiates a reflection part provided in each access point with a laser beam and receives the laser beam reflected by the reflection part, and a control part that obtains a first coordinate of the each access point by the laser tracker receiving the laser beam reflected by the reflection part, obtains a second coordinate of the measuring part on the basis of the wireless communication between the access point and the measuring part, causes the measuring part to measure a third coordinate of the workpiece, and obtains a spatial coordinate of the workpiece on the basis of the first coordinate, the second coordinate, and the third coordinate.

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.
