Abstract
In some examples, a scanning system comprises a reference structure comprising multiple fiducial objects arranged within an imaging volume of the scanning system, and a scanner to scan an object on a platform within the imaging volume of the scanning system to generate scan data, the scan data comprising a reference component representing the position of the multiple fiducial objects.
Claims15
A scanning system, comprising:
- a reference structure comprising multiple fiducial objects arranged within an imaging volume of the scanning system;
- and
- a scanner to scan an object on a platform within the imaging volume of the scanning system to generate scan data, the scan data comprising a reference component representing the position of the multiple fiducial objects.
A method for correcting a scan of an object, the method comprising:
- generating scan data of an object on a platform within an imaging volume of a scanning system using a scanner, the scan data comprising a first component representing a surface structure of a portion of the object, and a second component representing the positions of preselected points of multiple fiducial objects provided within the imaging volume of the scanning system;
- using the second component of the scan data, generating a correction on the basis of a difference between the positions and a set of reference values representing ground measurements of the positions of the preselected points;
- and
- modifying the first component using the correction to generate corrected data.
A non-transitory machine-readable storage medium comprising instructions executable by a processor, the machine-readable storage medium comprising instructions to:
- generate image data of an article on a platform within a field view of a scanning device of a scanning system;
- process the image data to determine the positions of multiple fiducial points within the field of view;
- use the determined positions of the multiple fiducial points to generate a correction factor;
- and
- apply the correction factor to an image of the article to generate a corrected article image.
