Panoramic Image Depth Extraction via Cubemap Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for obtaining depth information of panoramic images are ineffective in outdoor environments, making it difficult to achieve accurate depth data across various settings, including both indoor and outdoor environments.
Innovation Solution
A processing device and method that converts panoramic images from an initial format to a cubemap format, duplicates and connects view angle blocks, calculates depth information, performs blending processes, and stitches depth information blocks to generate a depth information image in cubemap format, which is then converted back to the original format, enabling the extraction of reliable depth data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current depth information obtaining methods are used, then indoor environment depth data can be obtained, but outdoor environment depth data cannot be obtained
Solution Approach 1:
The panoramic image is divided into multiple cubemap blocks (first cubemap block, second cubemap block, third cubemap block) that are processed separately. Each block undergoes independent depth calculation and blending, allowing the method to handle different environmental conditions in different regions of the panoramic image, thereby achieving both indoor and outdoor environmental adaptability while maintaining depth information reliability.
2Measurement precision
If panoramic image is converted to cubemap format and processed through multiple blending operations, then accurate depth information can be generated, but processing complexity increases
Solution Approach 1:
The processing is segmented into distinct stages: converting panoramic image to cubemap format, dividing into multiple blocks, calculating depth for each block, performing blending operations on overlapping regions, and stitching blocks together. This segmentation allows complex processing to be broken down into manageable steps, improving depth accuracy while making the complexity systematic and controllable.
Solution Approach 2:
The panoramic image is pre-converted to cubemap format and divided into blocks before depth calculation begins. This preliminary organization of data structure prepares the image for efficient processing, allowing subsequent depth calculations and blending operations to proceed systematically, thereby achieving high precision without unnecessary complexity during the actual depth extraction phase.
