Abstract
There is provided an image processing apparatus including a plurality of imaging units included in a stereo camera, the plurality of imaging units being configured to image a first chart pattern including a pattern that is a plurality of feature points and a mirror surface, and a correction parameter calculation unit configured to calculate a correction parameter that corrects a gap of the plurality of imaging units, based on the pattern included in the first chart pattern imaged by the plurality of imaging units and a pattern mirrored in the mirror surface.
Claims13
An image processing apparatus comprising:
- a plurality of imaging units included in a stereo camera, the plurality of imaging units being configured to image a first chart pattern including a pattern that is a plurality of feature points and a mirror surface;
- and
- a correction parameter calculation unit configured to calculate a correction parameter that corrects a gap of the plurality of imaging units, based on the pattern included in the first chart pattern imaged by the plurality of imaging units and a pattern mirrored in the mirror surface,
- wherein the plurality of imaging unit and the correction parameter calculation unit are each implemented via at least one processor.
An image processing method comprising:
- performing, by a plurality of imaging units included in a stereo camera image, imaging processing of imaging a first chart pattern including a pattern that is a plurality of feature points and a mirror surface;
- and
- performing correction parameter calculation processing of calculating a correction parameter that corrects a gap of the plurality of imaging units, based on a pattern included in a chart pattern imaged in multiple times of the imaging processing and a pattern mirrored in the mirror surface.
A non-transitory computer-readable medium having embodied thereon a program, which when executed by a computer causes the computer to execute a method, the method comprising:
- imaging a first chart pattern including a pattern that is a plurality of feature points and a mirror surface, by a plurality of imaging units included in a stereo camera;
- and
- calculating a correction parameter that corrects a gap of the plurality of imaging units, based on a pattern included in a chart pattern imaged in multiple times of processing in the imaging step and a pattern mirrored in the mirror surface.
An image processing system comprising:
- an image processing apparatus including a plurality of imaging units;
- and
- a chart pattern configured to calibrate on an imaging direction of the imaging units,
- wherein the chart pattern includes a pattern that is a plurality of feature points and provided in a position facing the plurality of imaging units, and a mirror surface,
- wherein the image processing apparatus includes the plurality of imaging units that are included in a stereo camera and image the chart pattern, and a correction parameter calculation unit that calculates a correction parameter which corrects a gap of the plurality of imaging units, based on the pattern included in the chart pattern imaged by the plurality of imaging units and a pattern mirrored in the mirror surface, and
- wherein the plurality of imaging unit and the correction parameter calculation unit are each implemented via at least one processor.
