1Ease of operation
If traditional 3D modeling methods are used, then 3D models can be generated, but the process is difficult and inconvenient to apply
Solution Approach 1:
The patent introduces a bit mask as an intermediary tool that simplifies the 3D modeling process. The bit mask selectively identifies and processes specific portions of image data, acting as a mediator between the raw image input and the 3D model output. This intermediary mechanism makes the complex 3D modeling process more manageable and easier to apply by allowing users to focus on specific regions of interest without dealing with the entire image complexity.
Solution Approach 2:
The patent divides the image data processing into segmented portions using bit masks. Instead of processing entire images at once, the system segments the image data into manageable portions that can be individually processed for 3D model generation. This segmentation approach reduces the operational complexity by breaking down the large-scale task into smaller, more manageable segments.
2Manufacturing precision
If comprehensive image data is processed, then accurate 3D models are achieved, but processing time and computational resources increase
Solution Approach 1:
The patent extracts only the necessary portions of image data using bit masks, rather than processing comprehensive image data. By taking out and processing only the relevant segments identified by the bit mask, the system achieves accurate 3D models of specific features while significantly reducing the overall processing time and computational resources required compared to processing entire images.
Solution Approach 2:
The patent applies partial action by processing only the portions of image data that are relevant to the specific 3D modeling task at hand. Instead of performing excessive processing on all image data, the bit mask enables selective processing of only the necessary segments, achieving sufficient accuracy for the intended application while minimizing processing time.

AI summary
Systems, methods, and computer-readable media for generating 3D models are disclosed. A method includes accessing an image depicting a dental arch of a user. The method further includes identifying, from the image, a set of features of the dental arch. The method further includes generating, using a convolutional neural network, a first voxel grid based on the set of features identified from the image, wherein a shape of the first voxel grid is generated based on a camera projection matrix accounting for a depth of the dental arch depicted in the image. The method further includes generating a 3D model including a 3D surface of the dental arch of the user based on a voxel grid from combining at least a portion of the first voxel grid and a portion of a second voxel grid.
