A positional calibration is enabled between an imaging device and a stage structure including X and Y stages that move independently of each other. An image processing apparatus performs the positional calibration of a camera coordinate system for an imaging device with a stage coordinate system using a reference position in a first image coordinate space indicating a position of a mark in an image captured when an X-stage is at a reference position, a displaced position in the first image coordinate space indicating a position of the mark in an image captured when the X-stage is at a first displaced position to which the X-stage moves in X-direction from the first reference position, and a virtual position in the first image coordinate space indicating a position of the mark in an image calculated using the characteristic value of a Y-stage.

Image processing apparatus, calibration method, and calibration program

A three-dimensional model data producing processing apparatus produces three-dimensional model data using design data (CAD data) of an object to be recognized. The three-dimensional model data producing processing includes processing conversion processing, edit processing, and teaching processing. The conversion processing and the edit processing are performed to the design data on a computer. The teaching processing is performed in a practical environment. It is not necessary to image a workpiece model in the three-dimensional model data producing processing.

Model producing apparatus, model producing method, and computer-readable recording medium in which model producing program is stored

A polygonal mark M having a shape in which a direction can be uniquely specified is attached to a predetermined area of an actual model WM of a work to be three-dimensionally recognized. A process of changing the orientation of the actual model WM such that a state in which the mark M is contained in the view of each camera is maintained, and then performing the three-dimensional measurement is executed over a plurality of times. A predetermined number of, or two or more pieces of three-dimensional information is selected from the three-dimensional information restored by each measurement, these pieces of three-dimensional information are aligned and integrated, the information corresponding to the mark is deleted or invalidated from the integrated three-dimensional information, and the three-dimensional information after such a process is set as a three-dimensional model.
