Illumination System with Marker-Based Object Localization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing illumination systems struggle to accurately and efficiently automate the illumination of objects on a stage due to the calculation-intensive nature of object detection and classification based on distance images, which can lead to precision issues and difficulties in differentiating between similar objects, especially when objects overlap or move dynamically.
Innovation Solution
The integration of a distance measuring unit and a marker system within the illumination system, where the distance measuring unit records depth information and the marker system provides additional signal-based information to individualize objects, allowing for precise localization and differentiation, thereby simplifying automation and decision-making processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If object detection and classification is performed based on distance images, then object localization is achieved, but calculation time increases and response speed decreases
Solution Approach 1:
The patent introduces markers as intermediary elements attached to objects. These markers emit or reflect specific signals that serve as mediators between the detection system and the objects, enabling rapid identification without complex image analysis. The markers act as a bridge that simplifies the detection process while maintaining precision.
Solution Approach 2:
The patent replaces the mechanical/computational process of analyzing distance images with a signal-based detection system. Instead of processing visual/depth data through complex algorithms, the system uses electromagnetic or optical signals from markers to directly identify and classify objects, significantly reducing calculation time.
2Measurement precision
If distance image analysis is used for object classification, then object identification is possible, but differentiation between similar objects becomes difficult
Solution Approach 1:
Markers serve as information carriers that provide unique identification data for each object. These markers contain or transmit individualized information that distinguishes between similar objects,弥补 the loss of discriminatory information that occurs during distance image processing.
Solution Approach 2:
The patent uses markers with different signal characteristics (analogous to color changes) to differentiate between objects. By varying the signal properties of markers—such as frequency, amplitude, or pattern—the system can easily distinguish between similar objects without relying solely on visual appearance or spatial position.
3Reliability
If full image processing is performed to locate objects, then comprehensive object detection is achieved, but processing complexity and computational load increase
Solution Approach 1:
The patent extracts the essential identification function from complex image processing by using markers. Instead of analyzing entire distance images to detect and classify objects, the system extracts simple signal detection from marker positions, dramatically reducing processing complexity while maintaining detection reliability.
Solution Approach 2:
Markers perform the identification function autonomously by emitting or reflecting their own unique signals. This self-service capability eliminates the need for complex external analysis systems, as each object essentially identifies itself through its marker, simplifying the overall detection system.
