Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional oral endoscope is used with professional operation, then imaging quality is ensured, but user interaction effect deteriorates and operation complexity increases
Solution Approach 1:
The patent enables users to perform oral cavity endoscopy themselves by holding and operating the device independently, eliminating the need for professional operators while maintaining imaging quality through automated processing functions
Solution Approach 2:
The system automatically adjusts imaging parameters and processes images through splicing and three-dimensional reconstruction algorithms, compensating for the lack of professional operation skill while ensuring high imaging quality
2Ease of operation
If user self-service oral endoscope is used, then ease of operation is improved, but ability to generate three-dimensional full dentition impression in real time deteriorates
Solution Approach 1:
The system pre-establishes a three-dimensional image frame database and image block library before actual scanning, enabling rapid matching and real-time three-dimensional reconstruction during user self-service operation
Solution Approach 2:
The patent uses image block splicing technology that copies and assembles pre-processed image blocks to reconstruct three-dimensional oral cavity structures, achieving efficient real-time modeling without requiring complex real-time processing during scanning
3Device complexity
If endoscopic images show only small parts at a time, then device simplicity is maintained, but information completeness deteriorates
Solution Approach 1:
The patent divides the oral cavity into multiple image blocks that are captured separately by the endoscope and then spliced together through image processing algorithms to form a complete three-dimensional view
Solution Approach 2:
The system transitions from two-dimensional single-view images to three-dimensional multi-dimensional reconstruction by splicing multiple image blocks and adding depth information, enabling complete oral cavity visualization while maintaining simple device structure

AI summary
The invention relates to the field of image processing, in particular, to an image processing method and device. The method comprises: obtaining image data and splicing to obtain a spliced image data block; matching an image data block containing the image data in the spliced image data block with images of blocks in a three-dimensional image frame database, updating a three-dimensional image model of a user and displaying according to a first preset displaying strategy if at least one mapping relation is obtained; displaying according to a second preset displaying strategy if the spliced image data block do not have mapping relation; if the preset conditions are met, the user's three-dimensional image model, the recorded number information of the blocks which have determined to obtain the mapping relationship and/or the image data blocks which have not obtained the mapping relationship are uploaded to the cloud server, so that the cloud server updates the three-dimensional image frame database, and the three-dimensional image can be obtained without continuously and orderly scanning the oral cavity, and the three-dimensional image frame database is continuously improved to improve the matching success rate.
