Patent Images
1. An image merging method, comprising the steps of:
- providing a plurality of calibration devices, being arranged corresponding to different positions of an object to be inspected, wherein each of the calibration devices includes a plurality of known characteristic information;
obtaining raw images of the calibration devices respectively, wherein each of the raw images corresponds to one of the calibration devices, each of the raw images includes a plurality of image characteristic information that are corresponding to the known characteristic information of its corresponding calibration device;
establishing a conversion formula according to the known characteristic information of each of the calibration devices and the image characteristic information of the corresponding image;
performing an analysis for obtaining position relationship between the raw images according to the conversion formula, comprising;
establishing a plurality of virtual point characteristic information, wherein the virtual point characteristic information for each raw image corresponds to a plurality of virtual images outside the raw image, and the virtual images are arranged to correspond to other raw images, wherein two virtual images can be inferred from each raw image; and
comparing and obtaining position relationships between raw images that are disposed neighboring to one another according to the conversion formula by the use of the image characteristic information and the virtual point characteristic information; and
merging the raw images.
