Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous driving systems often overlook shadows and reflections, which can provide valuable information about objects not directly visible in the scene, leading to incomplete scene understanding and potentially compromised safety.
Innovation Solution
The system utilizes shadow and reflection detection technologies, including ray tracing and shadow map techniques, to analyze electronic images and reconstruct information about occluding objects, thereby enhancing object detection and tracking for improved autonomous vehicle guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If conventional object detection systems only analyze directly visible objects, then the system complexity remains low, but the scene understanding completeness deteriorates
Solution Approach 1:
The patent uses shadows and reflections as intermediary elements to indirectly detect occluded objects. Instead of directly observing hidden objects, the system analyzes the shadows they cast and their reflections in surfaces, thereby recovering information about objects that would otherwise be invisible to the detection system.
Solution Approach 2:
The patent replaces direct optical detection with indirect detection methods using computational analysis of shadows and reflections. Rather than relying on direct line-of-sight optical paths, the system uses image processing algorithms to analyze light interaction patterns (shadows on surfaces, reflections in mirrors/water) to infer the presence and properties of occluded objects.
2Measurement precision
If the system incorporates shadow and reflection analysis, then object detection accuracy improves, but processing time increases
Solution Approach 1:
The patent segments the image processing task into distinct modules: direct object detection, shadow detection and analysis, reflection detection and analysis, and integration of results. This segmentation allows parallel processing of different detection streams and optimizes computational resources for each specific task, reducing overall processing time while maintaining comprehensive analysis.
3Reliability
If indirect information from shadows and reflections is utilized, then collision avoidance reliability improves, but computational requirements increase
Solution Approach 1:
The patent implements partial analysis by focusing computational resources on detecting and analyzing only the most informative shadows and reflections - those that provide critical information about occluded objects relevant to collision avoidance. Rather than analyzing every shadow and reflection in the scene, the system selectively processes those that contribute most to safety-critical decisions.
