An image processing apparatus, which receives an input image and detects an image of a target object based on a detection algorithm, includes a machine learning device which performs learning by using a plurality of partial images cut out from at least one input image, based on a result of detection of the image of the target object, and calculates a likelihood of the image of the target object.

Apparatus and method for image processing to calculate likelihood of image of target object detected from input image

For calibration on a single camera or a stereo camera, a calibration range is set in advance in an image coordinate system and the calibration is performed in an arbitrary range. A visual sensor controller is a calibration device that associates a robot coordinate system at a robot and an image coordinate system at a camera by placing a target mark at the robot, moving the robot, and detecting the target mark at multiple points in a view of the camera. The calibration device comprises: an image range setting unit that sets an image range in the image coordinate system at the camera; and a calibration range measurement unit that measures an operation range for the robot corresponding to the image range before implementation of calibration by moving the robot and detecting the target mark.

A parameter for detecting a target markis not required to be set for each camera repeatedly while a stereo camerais calibrated. A calibration deviceassociates position information in an image coordinate system at a first cameraof a stereo camera, position information in an image coordinate system at a second cameraof the stereo camera, and position information in a robot coordinate system at a robot. The calibration device comprises: first parameter setting unitthat sets a first parameter for detecting a target markattached to the robotfrom data about an image captured by the first camera; and a second parameter setting unitthat sets a second parameter for detecting the target markfrom data about an image captured by the second camerabased on the first parameter.

A contour line measurement apparatus includes an edge line extraction unit for setting a picture processing region and extracting an edge line from an object picture in each of the regions, an edge point generation unit for generating edge points which are intersections of the edge lines and epipolar lines, a corresponding point selection unit for selecting, from the plurality of edge points, a pair of edge points corresponding to the same portion of the reference contour line, and a three dimensional point calculation unit for calculating a three dimensional point on the contour line of the object on the basis of lines of sight of cameras which pass the pair of edge points.

A robot system display device is provided for graphically displaying components of a robot system which carries out a desirable process by measuring a position of a target object with a vision sensor. The robot system display device acquires an arrangement of the vision sensor relative to other components of the robot system based on calibration data for the vision sensor and pre-stored shape information of the vision sensor. The robot system display device graphically displays the vision sensor in a virtual space based on the relative arrangement.

A robot system calculates positional information of a workpiece with respect to a visual sensor and calculates positional information of an arm tip at a second time based on first times stored by a storing section and the second time at which the visual sensor measures the workpiece.
