Abstract
A method and an apparatus for detecting code of a holographic data page are provided. First, image information of at least one special pattern in the holographic data page is captured, and the captured image information is integrated into a characteristic symbol (CS) of the holographic data page. Then, the CS of the holographic data page is compared with a plurality of predetermined characteristic symbols (PCSs) to obtain a similarity between the CS and each of the PCSs. Thereafter, the PCS having the highest similarity to the CS is selected as the code information of the holographic data page.
Claims26
A code detection method for a holographic data page, comprising:
- capturing image information of at least one special pattern in the holographic data page, and integrating the captured image information into a characteristic symbol (CS) of the holographic data page;
- and
- comparing the CS of the holographic data page with a plurality of predetermined characteristic symbols (PCSs) to select the PCS which has a highest similarity to the CS as code information of the holographic data page.
A code detection apparatus for a holographic data page, comprising:
- an image capturing unit, for capturing image information of at least one special pattern in the holographic data page and integrating the captured image information into a CS of the holographic data page;
- a storage unit, for storing a plurality of PCSs;
- and
- a processing unit, for comparing the CS of the holographic data page with the PCSs and selecting the PCS having a highest similarity to the CS as code information of the holographic data page.
