Abstract: According to this feature point recognition system (1), data of a feature point of a first group obtained by a first algorithm calculation unit (12) with no mask processing is compared with data of a feature point of a second group detected by a third algorithm calculation unit (16) obtained through mask processing performed by a second algorithm calculation unit (14), whether the data is abnormal is determined, and thereby feature points of a subject P can be recognized more accurately and stably than in the related art.

Abstract: A tool checking device for a robot arm includes: an image processing unit configured to perform, on a captured image of a tool attached to the robot arm, image processing associated with a tool condition regarding a tool type or tool state that needs to be satisfied by the tool, and generate a processed image in which a related area associated with the tool condition is extracted; and a determination unit configured to determine whether the tool attached to the robot arm satisfies the tool condition, on the basis of the processed image.

Abstract: A tool checking device for a robot arm includes: a tool movement control unit configured to control the robot arm so as to move a tool attached to the robot arm to a defined position; an imaging control unit configured to control an imaging device so as to capture an image of the tool moved to the defined position; and a determination unit configured to determine whether the tool satisfies a tool condition regarding a tool type or tool state that needs to be satisfied, on the basis of a captured image imaged by the imaging device.

Abstract: A tool check device for robot arm, includes: a movement control unit configured to control a robot arm such that a tool to be attached to the robot arm is arranged at a first axis coordinate, of a three-dimensional coordinate system, according to a tool condition concerning at least either of a type or a state of the tool in an inspection space defined as the three-dimensional coordinate system; a distribution data acquisition unit configured to acquire distribution data, of an object in the inspection space, indicated by a combination of a second axis coordinate and a third axis coordinate of the three-dimensional coordinate system, after the control by the movement control unit; and a determination unit configured to determine whether the tool condition is satisfied, based on the distribution data.
