Abstract: A laser processing system having a measurement function. The laser processing system includes a processing head configured to irradiate an object with a laser beam in a scanning manner via an optical system for processing; an illumination-light emitting section provided in the processing head, and configured to cause illumination light to be emitted from the processing head toward the object along an optical axis of the optical system for processing; a light receiving section located in a predetermined positional relationship with the illumination-light emitting section, and configured to receive a reflection of the illumination light reflected at an irradiated point on the object; and a measurement section configured to process the reflection received by the light receiving section and obtain three-dimensional measurement data of the irradiated point.

Abstract: A detection apparatus for detecting a three-dimensional position of an object includes a feature point detecting unit that, with consecutive or at least alternately consecutive two images among multiple images sequentially imaged when a robot is moving being a first image and a second image, detects multiple feature points in the second image including one feature point detected in the first image; a distance calculating unit that calculates a distance between the one feature point of the first image and the multiple feature points of the second image; and a feature point determining unit that determines a feature point for which the distance is the shortest. With consecutive or at least alternately consecutive next two images being the first image and the second image, processing for determining a feature point for which the distance is the shortest is repeated, thereby tracking the feature points of the object.

Abstract: A safety management method sets a third space that both a worker and a robot can enter between a first space in which the worker is present and a second space in which the robot is disposed; sets, between the first space and the third space and between the second space and the third space, respectively, boundaries for monitoring crossing thereof; monitors the presence/absence of the robot or the worker in the third space; when a state of crossing of one boundary and a state of the worker or the robot in the third space are simultaneously switched to “detection”, restricts the operation of the robot, when crossing of another boundary is detected; and not restricts the operation of the robot when the state of crossing of the one boundary and the state of the worker or the robot in the third space are simultaneously switched to “non-detection”.
