Abstract: The parameters of image processing are adjusted for detecting a workpiece, by quantifying the quality of the parameters of the image processing. This image processing device automatically adjusts detection parameters that are used in image processing for detecting an imaging object. The image processing device includes a detection parameter generation unit that generates detection parameter combinations, an imaging condition setting unit that sets imaging conditions for each of the detection parameter combinations, a detectability determination unit that determines whether or not the imaging object is detectable for each combination of detection parameters and imaging conditions, an imaging range calculation unit that calculates a range of imaging conditions under which the imaging object is determined, by the detectability determination unit, to have been detected, and a parameter determination unit that determines a detection parameter combination for which the calculated range of imaging conditions is the widest.

Abstract: A robot system including a robot, an image capturing device, and a controller. The controller and the image capturing device have clocks, the controller conducts transmission of, to the image capturing device, an image-capturing instruction including a predetermined waiting time, the predetermined waiting time being a time between a time of the transmission and an image capturing time, or a required time obtained by subtracting, from the waiting time, a difference time between the time of the transmission and receiving time of the image-capturing instruction, the image capturing device conducts image capturing of an image of the workpiece at time when the required time elapses from the receiving time and transmits image data, and the controller controls the robot based on position information of the robot at time when the waiting time elapses from the time of the transmission and the image data.

Abstract: Provided is a robot capable of automatically confirming the accuracy of a three-dimensional sensor and correcting the accuracy. The robot comprises: a three-dimensional sensor; a notification unit for notifying a determination timing for determining a deviation of an optical system of the three-dimensional sensor, on the basis of a change in a physical quantity related to the three-dimensional sensor; and a determination unit for determining whether or not there is a deviation at the optical system of the three-dimensional sensor. The change in the physical quantity includes at least one of acceleration and the number of times of acceleration and deceleration added to the three-dimensional sensor, a change in temperature of the three-dimensional sensor within a certain period, a change in temperature of the three-dimensional sensor within a total operating period, and the number of times of change in temperature of the three-dimensional sensor within the total operating period.
