Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for capturing superimposed distance and intensity images face challenges in achieving high-quality, real-time image capture under varying environmental conditions, particularly with less reflective surfaces, due to limitations in radiation alignment and noise in intensity data acquisition.
Innovation Solution
The device incorporates a radiation deflection unit with a one-part or two mechanically rigidly coupled deflection elements, optimizing the spatial relationship between distance and intensity image measuring systems, allowing for direct superimposition of distance and intensity data without time-consuming conversions, even under harsh conditions like vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separately supported pivotable prisms with toothed belt coupling are used for radiation deflection, then the device can capture distance and intensity images, but the mechanical coupling introduces complexity and potential instability in the spatial relationship between the two measuring systems
Solution Approach 1:
The patent combines the radiation deflection functions for both distance measurement radiation and intensity measurement radiation into a single radiation deflection unit with one-part deflection elements. This eliminates the need for separate pivotable prisms and their mechanical coupling, thereby reducing device complexity while maintaining the capability to capture both distance and intensity images.
Solution Approach 2:
The radiation deflection unit is designed to handle both distance measurement radiation and intensity measurement radiation simultaneously through its one-part deflection elements. This multi-functional approach replaces the need for separate deflection mechanisms, simplifying the overall device structure while preserving adaptability for dual imaging modes.
2Adaptability or versatility
If separate deflection elements are used for distance and intensity radiation, then each system can be optimized independently, but maintaining a fixed spatial relationship between the two systems becomes difficult under harsh conditions like vibrations
Solution Approach 1:
By merging the deflection functions into a single radiation deflection unit with one-part deflection elements, the patent ensures that both distance and intensity radiation follow the same optical path and are subject to identical mechanical movements. This eliminates relative positional drift between the two systems under vibrations while maintaining the ability to optimize radiation properties for both imaging modes.
Solution Approach 2:
The one-part deflection element acts as an intermediary that uniformly affects both distance measurement radiation and intensity measurement radiation. This mediator ensures that both radiation types maintain a fixed spatial relationship throughout the measurement process, even under harsh environmental conditions, by subjecting them to identical deflection movements.
3Measurement precision
If time-consuming conversions are performed to superimpose distance and intensity data, then accurate alignment can be achieved, but real-time image capture is compromised
Solution Approach 1:
The patent establishes the fixed spatial relationship between distance and intensity measurement systems through preliminary calibration during system setup. Once calibrated, the one-part deflection elements maintain this relationship automatically during operation, eliminating the need for time-consuming conversions during real-time image capture while preserving positionally accurate superimposition.
4Device complexity
If intensity radiation is not optimized for the specific measurement task, then the system is simpler, but noise levels increase particularly on less reflective surfaces
Solution Approach 1:
The patent optimizes intensity radiation parameters such as wavelength and beam shape through the intensity radiation source to enhance performance on less reflective surfaces. This parameter optimization improves intensity data quality and reduces noise without significantly increasing system complexity, as it involves adjusting existing system parameters rather than adding complex components.

Data Source
AI summary
An apparatus for capturing superimposed distance and intensity images includes a distance image measuring arrangement provided with a distance radiation source, an intensity radiation source, a distance detection unit and an intensity detection unit. Distance measurement radiation from the distance radiation source and intensity measurement radiation from the intensity radiation source are incident on an area of a surface of a test object via a jointly used radiation deflection unit. The optical components of the distance image measuring arrangement and the intensity image measuring arrangement are mounted on a support structure in a fixed spatial relationship with respect to each other. Distance and intensity images are thus superimposed in an optically positionally accurate manner to produce high-quality real-time images.
