Abstract: An orthogonal state measuring device includes a measurement table and a CCD camera displacing in X, Y, and Z directions relative to the measurement table and measuring a work piece placed on the measurement table. The orthogonal state measuring device further includes a wide angle surveillance camera, a computer main body, and a display. The wide angle surveillance camera captures in one pass an image that is capable of configuring a bird's-eye image of the work piece, the bird's-eye image encompassing an entire field over which the CCD camera is capable of relative displacement. The computer main body generates the bird's-eye image based on the image and defines a position of the CCD camera on the bird's-eye image, then configures navigation maps in which the position of the CCD camera is composited on the bird's-eye image. The display displays the navigation maps.

Abstract: Provided is an image measurement system including: a placement portion on which a measurement object is placed; an imaging unit configured to be relatively movable with respect to the placement portion; a movement control unit that switches between a high-speed movement mode and a low-speed movement mode and allows the imaging unit to relatively move with respect to the placement portion; and an imaging control unit that captures instantaneous image information by the imaging unit on the basis of switching to the low-speed movement mode.

Abstract: An image measurement device according to the present invention comprises: a stage on which a measurement object is mounted; an imaging device imaging the measurement object for a certain imaging range and outputting image information; a position control device that moves the imaging device to a plurality of measurement positions and scans in a scanning direction; and an arithmetic processing device that calculates a displacement of the measurement object. The imaging device is configured capable of imaging a preliminary measurement range broader than the certain imaging range. The arithmetic processing device, prior to a main measurement that measures the displacement of the measurement object at each measurement position, makes a preliminary measurement based on the image information corresponding to the preliminary measurement range, and sets a scanning range of the imaging device at each measurement position during the main measurement based on a result of this preliminary measurement.
