Solution Overview
Problem
Existing object detection systems using light for detection accuracy may require further improvement depending on the application.
Innovation Solution
An object detection system comprising a ranging device that emits light and receives reflected light, with a reflection member provided in the scan range to reflect light back towards the ranging device, enhancing detection accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a ranging device emits light to detect objects in a detection region, then object detection capability is achieved, but detection accuracy is insufficient for certain applications
Solution Approach 1:
A reflection member is introduced as an intermediary element between the ranging device and the detection region. This reflection member reflects light that has passed through the detection region back toward the ranging device, creating a reference signal that enhances the detection accuracy of objects in the detection region without interfering with the primary detection function.
2Illumination intensity
If light is emitted through the detection region to detect objects, then object detection is enabled, but signal intensity is insufficient in regions without objects
Solution Approach 1:
The reflection member serves as a mediator that returns light through the detection region, creating a reference signal path. This reference signal provides intensity information for regions without objects, enabling the system to distinguish between absent and present objects and thereby preserving spatial resolution information that would otherwise be lost.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system achieves improved detection accuracy by increasing signal intensity in regions without objects, thereby enhancing the Signal to Noise (S/N) ratio and spatial resolution.
Implementation Method 1
a reflection member that is provided in a scan range so as to reflect light passing through the detection region toward the ranging device
