Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal detection devices face inaccuracies due to manual input of distance values, inability to adjust temperature data actively, and difficulty in detecting multiple or moving target objects simultaneously, leading to inconvenient usage.
Innovation Solution
A thermal detection device equipped with a first camera, a second camera, and a thermal camera, along with a processor that captures images to measure distances and object sizes, allowing for automatic adjustment of measurement temperatures by determining a second temperature value based on the first temperature value, distance, and object size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual input of distance value is used, then device complexity is reduced, but measurement precision deteriorates
Solution Approach 1:
The patent replaces manual input (mechanical interaction) with an automatic distance detection system using cameras and image processing. The first and second cameras capture images, and the processor automatically calculates distance based on image analysis, eliminating manual input while improving measurement precision.
2Measurement precision
If automatic distance measurement is implemented, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent makes the camera system multi-functional by using it for both distance measurement and object size measurement. The same first and second cameras serve multiple purposes, reducing the need for additional specialized sensors and thereby limiting the increase in device complexity.
Solution Approach 2:
The patent divides the measurement function into segments: distance measurement using the camera pair and object size measurement using the same cameras. This segmentation allows each component to be optimized for specific tasks while working together as an integrated system.
3Adaptability or versatility
If thermal camera detects temperature only, then device complexity is reduced, but adaptability deteriorates
Solution Approach 1:
The patent merges thermal detection with visual detection by integrating the thermal camera with the first and second cameras. The processor combines temperature data with distance and size information to provide comprehensive target analysis, enhancing adaptability while sharing hardware resources.

AI summary
A thermal detection device includes a first camera, a second camera, a thermal camera, and a processor. The thermal camera is disposed between the first camera and the second camera, and detects a to-be-measured object to generate a first temperature value. The processor includes a control unit, which controls the first camera and the second camera according to settings of a first measurement mode and a second measurement mode. In the first measurement mode, the control unit captures images from the first camera and the second camera to measure a first distance between the to-be-measured object and an installation surface. In the second measurement mode, the control unit captures images from the first camera to measure a size of the to-be-measured object. The processor determines a second temperature value of the to-be-measured object according to the first temperature value, the first distance, and the size of the to-be-measured object.
