Object-Dependent Image Illumination Using Tracking Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image acquisition technologies face challenges in achieving uniform illumination of complex-shaped objects due to the low dynamic range of cameras, leading to exaggerated illumination contrasts and difficulties in correcting lighting issues post-processing, especially when dealing with moving objects or those requiring precise three-dimensional representations.
Innovation Solution
An apparatus and method that utilize tracking information to control adjustable light sources based on the orientation, location, or distance of an object within the camera's field-of-view, optimizing illumination to avoid shadows and overexposure by deriving an approximate three-dimensional representation without the need for precise sensor data or computationally expensive point cloud generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a three-dimensional representation is generated to control lighting, then illumination precision is improved, but computational cost and sensor data requirements increase
Solution Approach 1:
The patent uses a simplified two-dimensional copy or projection of the object's spatial properties instead of generating a complete three-dimensional representation. Tracking information such as orientation, location, and distance is used to create a sufficient approximation for lighting control without the computational burden of full 3D modeling
Solution Approach 2:
The patent applies partial action by using only the necessary tracking information (orientation, location, distance) required for effective lighting control rather than capturing complete three-dimensional data. This provides sufficient illumination precision while avoiding excessive computational requirements
2Manufacturing precision
If complex three-dimensional data is collected for object representation, then lighting accuracy is improved, but data processing time and computational resources increase
Solution Approach 1:
The system uses a simplified representation copying only the essential spatial properties (orientation, location, distance) needed for lighting control, avoiding the time-consuming process of collecting and processing complete complex three-dimensional data
Solution Approach 2:
The patent performs preliminary action by using pre-acquired tracking information that is already available from the camera system, rather than collecting additional complex three-dimensional data at the moment of image capture, thus reducing processing time
3Reliability
If uniform illumination is achieved through precise lighting control, then image quality is improved, but system complexity increases
Solution Approach 1:
The system uses self-service by leveraging the camera's existing tracking capabilities to automatically control the lighting, rather than requiring separate complex three-dimensional sensing systems. The tracking information from the camera itself serves the dual purpose of object detection and lighting control
Solution Approach 2:
The patent applies universality by using the camera's tracking system for multiple functions: both object detection/identification and lighting control. This multi-functionality reduces overall system complexity while maintaining image quality
