Solution Overview
Problem
Common image collecting processing systems face challenges with reduced accuracy due to light reflection from rain and the need to process all pixels in an initial image, leading to increased processing time and information volume.
Innovation Solution
An image collecting system that includes a pick-up device and a polarizing device, where the polarizing device is positioned to allow first and second incident light to have different polarization states, reducing the impact of rain-reflected light and generating a target image by comparing first and second images acquired by the system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a conventional image collecting system is used to capture images through rain, then the system can acquire image data, but the accuracy is reduced due to light reflection from rain water on the windshield
Solution Approach 1:
A polarizing device is introduced as an intermediary component between the pick-up device and the external environment. This polarizing device selectively filters light based on its polarization state, allowing light from the target scene to pass through while blocking reflected light from rain water on the windshield, thereby improving image accuracy without requiring complex post-processing
Solution Approach 2:
The system changes the polarization state parameter of incident light by using a polarizing device. By controlling which polarization states are allowed to pass through, the system can selectively transmit light from the target scene while blocking reflected light, thus improving image quality under rainy conditions
2Measurement precision
If all pixels in the initial image are processed to improve image quality, then image accuracy may be improved, but the processing time and amount of image information processing increase significantly
Solution Approach 1:
The polarizing device performs preliminary filtering of light before it enters the pick-up device. By physically blocking reflected light at the optical level, the system prevents harmful information from being captured in the first place, eliminating the need for extensive post-processing to remove rain reflection artifacts
Solution Approach 2:
The system extracts only the necessary light information by using the polarizing device to selectively transmit light with specific polarization states. This extraction of relevant information at the optical level reduces the amount of data that needs to be processed later, decreasing processing time and computational load
