METHOD AND APPARATUS WITH GRID MAP GENERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17865667 titled 'METHOD AND APPARATUS WITH GRID MAP GENERATION
Simplified Explanation
The patent application describes a method for generating a grid map using position and detection information from sensors on a moving object. Here are the key points:
- The method involves determining the position of the moving object using a position sensor and detecting nearby objects using a radar sensor.
- A still object within the moving range of the object is selected based on the position and detection information.
- The point cloud, generated from the radar sensor in a previous time step, is updated using the position and detection information of the selected still object.
- A grid map is then generated based on the occupancy probability of each grid in the updated point cloud.
Potential Applications
This technology has potential applications in various fields, including:
- Autonomous vehicles: The method can be used to generate accurate grid maps for autonomous vehicles, aiding in navigation and obstacle avoidance.
- Robotics: It can be utilized in robotics for mapping and understanding the environment, enabling robots to perform tasks efficiently and safely.
- Surveillance systems: The method can enhance surveillance systems by providing detailed grid maps for monitoring and tracking objects in real-time.
Problems Solved
The method addresses several problems in grid map generation:
- Accurate object detection: By using both position and radar detection information, the method improves the accuracy of detecting nearby objects.
- Dynamic environment mapping: The method allows for updating the point cloud in real-time, enabling the grid map to adapt to changes in the environment.
- Still object selection: By selecting still objects within the moving range, the method focuses on relevant objects for grid map generation, reducing unnecessary data processing.
Benefits
The use of this method offers several benefits:
- Improved mapping accuracy: By incorporating position and detection information, the grid map generated is more accurate and reliable.
- Real-time updates: The method allows for real-time updates of the point cloud, ensuring the grid map reflects the current state of the environment.
- Efficient data processing: By selecting still objects, the method reduces the amount of data processed, leading to more efficient mapping and navigation systems.
Original Abstract Submitted
A method with grid map generation includes: determining position information of a moving object corresponding to a first time step based on a position sensor of the moving object; determining detection information of nearby objects present around the moving object corresponding to the first time step based on a radio detection and ranging (radar) sensor of the moving object; selecting a still object in a moving range of the moving object from among the nearby objects, based on the position information and the detection information; updating a point cloud determined based on the radar sensor in a previous time step of the first time step, based on the position information and on detection information of the still object comprised in the detection information of the nearby objects; and generating a grid map based on an occupancy probability for each grid of the updated point cloud.
