Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies struggle to capture and generate 3D panoramic images effectively in bright light conditions, such as those found in outdoor environments, and require significant post-production work to address holes in 3D renderings caused by bright light sources, while also being inefficient in capturing and processing digital images.
Innovation Solution
A system comprising a housing with a wide-angle lens, an image capture device, and a LiDAR device configured to generate depth data, along with motors for rotation and a spinning mirror to capture images and depth signals, allowing for efficient 3D panoramic image generation with reduced parallax and improved brightness handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing technologies are used to capture 3D data in bright light conditions, then the capture process can be completed, but the 3D rendering contains holes and requires additional post-production work
Solution Approach 1:
The patent performs preliminary actions by capturing multiple images at different exposures before the bright light causes problems. The system captures a first image at a first exposure and a second image at a second exposure, then blends them to create a high dynamic range image that prevents holes in the 3D rendering before they occur.
Solution Approach 2:
The patent converts the harmful effect of bright light (which causes holes in 3D renderings) into a benefit by using the bright light information from one exposure to fill in dark areas, while using dark area information from another exposure to fill in bright areas, creating a complete high dynamic range image that eliminates rendering holes.
2Manufacturing precision
If multiple images are captured and processed to create 3D panoramic images, then the quality of the 3D rendering is improved, but the time required to capture and process the images increases
Solution Approach 1:
The patent merges multiple images captured at different exposures into a single high dynamic range image. By combining the information from the first image (captured at first exposure) and the second image (captured at second exposure), the system creates a blended image that contains both bright and dark area information, improving 3D panoramic image quality while reducing the need for extensive post-production processing.
