Solution Overview
Problem
Existing object detection systems face challenges in effectively detecting objects in environments with low light conditions, as camera-based sensors are sensitive to lighting and prone to false alarms, while radar-based sensors lack detailed information.
Innovation Solution
A combined camera and radar object detection system that includes a camera with a first field of view, a radar antenna with a second field of view, and an actuator to move the camera. The system uses a processor to integrate data from both modules, enhancing detection capabilities by compensating for limitations in each technology.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If camera-based sensors are used for object detection, then detailed information about detected objects can be obtained, but the system is sensitive to lighting conditions and prone to false alarms in low light environments
Solution Approach 1:
The patent combines camera-based sensors and radar-based sensors into a hybrid detection system. The camera module provides detailed visual information when lighting conditions are favorable, while the radar module provides reliable detection in low light conditions. By merging both systems and using a processor to integrate their outputs, the patent resolves the contradiction between obtaining detailed object information and maintaining reliable detection across varying lighting conditions.
2Reliability
If radar-based sensors are used for object detection, then reliable detection in low light conditions is achieved, but detailed information about detected objects is lacking
Solution Approach 1:
The patent merges radar-based sensors with camera-based sensors to complement each other's strengths. The radar module ensures reliable detection in low light conditions, while the camera module supplements detailed object information when available. The processor integrates both data streams, assigning appropriate weight to each based on environmental conditions, thereby resolving the contradiction between reliable detection and detailed information gathering.
3Reliability
If a combined camera and radar system is implemented, then detection reliability and detail are improved, but system complexity increases
Solution Approach 1:
The patent implements a multi-functional detection system where both camera and radar modules operate under a unified control architecture. The processor serves multiple functions: processing camera images, processing radar signals, comparing detections from both sensors, and controlling the camera actuator. This universal approach manages system complexity by consolidating control functions rather than creating separate independent systems.
Solution Approach 2:
The system uses feedback mechanisms where the processor continuously compares detections from both sensors and adjusts camera positioning based on radar information. The actuator receives feedback signals to reposition the camera based on radar-detected object locations. This feedback loop integrates the two sensor systems dynamically, managing complexity through coordinated operation rather than static integration.
