EXTERNAL ENVIRONMENT RECOGNITION APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18401552 titled 'EXTERNAL ENVIRONMENT RECOGNITION APPARATUS
The abstract describes an external environment recognition apparatus for vehicles, which includes an in-vehicle detector that scans and emits electromagnetic waves to detect the surrounding environment, and a microprocessor that acquires road surface information based on the detector's data.
- The in-vehicle detector captures three-dimensional point cloud data frame by frame.
- The microprocessor recognizes the road surface and objects on the road based on the point cloud data.
- The apparatus determines the scanning angular resolution of the electromagnetic wave based on the size of objects and the distance from the vehicle.
Potential Applications: - Autonomous driving systems - Advanced driver assistance systems - Traffic management and monitoring
Problems Solved: - Enhances road safety by providing real-time information about the road surface and objects on the road. - Improves the accuracy of environmental perception for vehicles.
Benefits: - Increased safety for drivers and pedestrians - Enhanced efficiency in navigation and traffic flow - Potential reduction in accidents and collisions
Commercial Applications: Title: "Advanced External Environment Recognition System for Vehicles" This technology can be utilized by automotive manufacturers, transportation companies, and smart city initiatives to improve road safety, traffic management, and overall driving experience.
Questions about the technology: 1. How does the apparatus differentiate between different types of objects on the road? - The apparatus uses the size and distance of objects to determine the scanning resolution of the electromagnetic wave. 2. What are the potential challenges in implementing this technology in real-world driving scenarios? - Challenges may include processing large amounts of data in real-time and ensuring the accuracy of object recognition.
Original Abstract Submitted
An external environment recognition apparatus including: an in-vehicle detector configured to scan and emit an electromagnetic wave in a first direction and as a second direction to detect an external environment situation around a subject vehicle; and a microprocessor configured to acquire road surface information based on a detection data of the in-vehicle detector. The in-vehicle detector acquires a three-dimensional point cloud data frame by frame, and the microprocessor is configured to perform: recognizing a surface of the road and a three-dimensional object on the road for each frame as the road surface information based on the three-dimensional point cloud data, and determining an interval of detection points of the three-dimensional point cloud data of a next frame as a scanning angular resolution of the electromagnetic wave based on a size of a predetermined object and a distance from the subject vehicle to the object.
