Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional three-dimensional radiation detection and visualization systems using two sensing modules are heavy, costly, and require complex coordinate conversions, limiting their operability and marketability, as they cannot accurately determine the distance and intensity of a radiation source.
Innovation Solution
A symmetrical-type mono-sensor system with one radiation sensor and one image sensor, where the sensors are independently arranged and rotated using pan/tilt motors to minimize coordinate conversion errors, allowing for accurate three-dimensional radiation detection and visualization without the need for two sensing modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If two sensing modules are used to obtain distance information to the radiation source, then measurement precision is improved, but device complexity and weight increase
Solution Approach 1:
The patent divides the sensing system into two independent modules: a radiation sensor module for detecting radiation sources and an image sensor module for capturing visible images. This segmentation allows each module to specialize in its function while working together to provide three-dimensional information, resolving the contradiction by achieving accurate distance measurement without requiring two complete sensing modules
Solution Approach 2:
The patent introduces a temporal dimension by capturing radiation information and image information at different time points. The radiation sensor captures radiation data first, then the image sensor captures the corresponding visible image, allowing the system to calculate distance through time-based coordinate conversion rather than requiring simultaneous dual-module detection
2Measurement precision
If two sensing modules are used to obtain distance information, then measurement precision is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the system into separate radiation sensing and image sensing modules, the patent avoids the need to manufacture and integrate two complete dual-function sensing modules. Each module can be optimized and manufactured independently, reducing overall manufacturing complexity and cost while still achieving three-dimensional radiation detection capability
Solution Approach 2:
The patent uses the image sensor to capture a visible copy of the radiation scene, which is then overlaid with the radiation information. This visual copy serves as a reference framework that allows accurate spatial mapping and distance calculation without requiring duplicate radiation sensing hardware
3Measurement precision
If coordinate conversion is performed in stereo radiation imaging devices, then three-dimensional detection is achieved, but error occurrence increases
Solution Approach 1:
The patent performs preliminary calibration and coordinate system establishment before actual radiation detection. The image coordinate system and radiation sensor coordinate system are pre-aligned and calibrated, so that when detection occurs, the coordinate conversion between the two systems is straightforward and error-minimized rather than requiring complex real-time transformations
4Device complexity
If one sensing module is used, then device complexity is reduced, but distance information cannot be obtained
Solution Approach 1:
The patent merges the functionality of radiation detection and visual imaging into a unified system where the radiation sensor and image sensor work together. By combining the radiation data with the visual image data from the single sensing module, the system recovers the distance information that would normally require two separate modules, thus eliminating information loss while maintaining simplicity
