VEHICLE LIDAR SYSTEM AND OBJECT DETECTION METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17983771 titled 'VEHICLE LIDAR SYSTEM AND OBJECT DETECTION METHOD THEREOF
Simplified Explanation
The abstract describes a method for detecting objects using a LiDAR system in a vehicle. Here is a simplified explanation of the abstract:
- The method involves creating a grid map based on freespace point data and object information.
- The grid map includes grids that represent the host vehicle lane, with the size of the grids determined by the lane width.
- The method calculates a road boundary candidate by analyzing the occupation percentages of objects in each lane and the distribution of the freespace point data.
- The calculated road boundary candidate is then adjusted based on information from a previous time point to improve accuracy.
- The method outputs road boundary information, which can be used for various purposes such as navigation or autonomous driving.
Potential applications of this technology:
- Autonomous driving systems can use the road boundary information to navigate and stay within the designated lanes.
- Advanced driver-assistance systems (ADAS) can utilize the road boundary information to provide warnings or assistance to the driver.
- Traffic management systems can benefit from the accurate road boundary information for monitoring and controlling traffic flow.
Problems solved by this technology:
- Accurate detection of road boundaries is crucial for safe and efficient navigation.
- Traditional methods may struggle with detecting road boundaries accurately in complex or dynamic environments.
- This technology addresses these challenges by combining freespace point data, object information, and historical data to calculate and adjust the road boundary candidate.
Benefits of this technology:
- Improved accuracy in detecting road boundaries, leading to safer navigation and reduced risk of accidents.
- The method can adapt to changing road conditions by incorporating historical data, ensuring reliable performance in various environments.
- The grid-based approach allows for efficient processing and analysis of the LiDAR data, making it suitable for real-time applications.
Original Abstract Submitted
An object detection method of a vehicle LiDAR system includes setting grids including a host vehicle lane according to a lane width on a grid map which is generated based on freespace point data and object information, and calculating a road boundary candidate based on occupation percentages of objects by lane calculated based on the object information and distributions of the freespace point data; and outputting road boundary information by correcting the calculated road boundary candidate based on information on a road boundary candidate determined at a previous time point.
