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.
Claims19
An image measurement system, comprising:
- a stage on which a measurement object is placed;
- a camera configured to be relatively movable with respect to the placement portion;
- a processor that controls a movement controller and an imaging controller, wherein the processor controls the movement controller and the imaging controller so that:
- the movement controller switches between a high-speed movement mode and a low-speed movement mode and allows the camera to relatively move with respect to the stage;
- and
- the imaging controller captures instantaneous image information by the camera, wherein
- the movement controller relatively moves the camera with respect to the stage on the low-speed movement mode within a first movement range in which a relative position of the camera with respect to the stage includes a predetermined imaging position and relatively moves the camera with respect to the stage on the high-speed movement mode within a second movement range outside the first movement range, and
- imaging controller captures, after the movement controller moves the relative position of the camera with respect to the stage to a predetermined imaging position on the low-speed movement mode, the instantaneous image information at the predetermined imaging position.
An image measurement method, comprising the steps of:
- providing camera;
- providing a stage on which a measurement object is placed;
- switching between a high-speed movement mode and a low-speed movement mode and relatively moving the camera with respect to the stage on which a measurement object is placed;
- and
- capturing instantaneous image information by the camera, wherein
- relatively moving the camera includes relatively moving the camera with respect to the stage on the low-speed movement mode within a first movement range in which a relative position of the camera with respect to the stage includes a predetermined imaging position and relatively moving the camera with respect to the placement portion on the high-speed movement mode within a second movement range outside the first movement range, and
- capturing the instantaneous image information includes capturing, after moving the relative position of the camera with respect to the stage to the predetermined imaging position on the low-speed movement mode, the instantaneous image information at the predetermined imaging position.
