Abstract
A method for correcting an image is provided. The method includes: mapping a regular grid according to the length and the width of a work plane of a measuring machine, and a preconfigured interval of the grid, wherein intersecting points of the regular grid refer to reference points; computing deviation values of all the reference points; capturing a digital image of a physical object through the measuring machine; correcting the real coordinate value of all points of the digital image according to the deviation values of the reference points. A related system is also provided.
Claims8
A system for correcting an image, the system comprising a computer and a measuring machine, the measuring machine comprising a charge coupled device configured for capturing a digital image of a physical object, the computer comprising an image acquiring card for receiving the digital image from the charge coupled device, and the computer further comprising:
- an image correction program configured for correcting the digital image, the image correction program comprising:
- a deviation value computing module configured for mapping a regular grid according to the length and the width of a work plane of the measuring machine, and a preconfigured interval of the grid, wherein intersecting points of the regular grid refer to reference points;
- the deviation values computing module further configured for computing deviation values of the reference points;
- and
- a correction module configured for correcting real coordinate values of points of the digital image according to the deviation values of the reference points.
