TRACKING DEVICE, TRACKING METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18463967 titled 'TRACKING DEVICE, TRACKING METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM
Simplified Explanation
The patent application describes a method for tracking a target object using dimensional information of an observation space and the relative velocity of the target object with respect to a sensing device.
- The method involves estimating the state of the target object at a specific time and assuming a reflection source of the observed reflection wave based on this estimation.
- The state validity of the estimation is determined, and the estimation state is updated based on the difference between the dimensional information of the reflection source projected onto the observation space in the estimation state and the observation information.
Potential Applications
- Surveillance systems: This technology can be used in surveillance systems to track moving objects and identify potential threats.
- Autonomous vehicles: The method can be applied in autonomous vehicles to track other vehicles or pedestrians and make informed decisions based on their movements.
- Robotics: This tracking method can be used in robotic systems to track objects or humans in real-time, enabling more accurate and efficient interactions.
Problems Solved
- Accurate tracking: The method solves the problem of accurately tracking a target object by considering the dimensional information of the observation space and the relative velocity of the object.
- Reflection source estimation: By assuming a reflection source based on the estimation state, the method improves the accuracy of tracking by considering the specific characteristics of the observed reflection wave.
Benefits
- Improved tracking accuracy: By considering the dimensional information and relative velocity, the method provides more accurate tracking of target objects.
- Real-time tracking: The method allows for real-time tracking of moving objects, enabling timely decision-making and response.
- Robustness: The state validity determination and updating process ensure that the estimation state remains valid and accurate, even in dynamic environments.
Original Abstract Submitted
A target object is tracked based on dimensional information of an observation space including a relative velocity of the target object with respect to a sensing device for observing a reflection wave from the target object. An estimation state is acquired by estimating a state of the target object at a specific time. A reflection source of the reflection wave that gives an observation point observed at the specific time is assumed with respect to the estimation state. A state validity of the estimation state is acquired. The estimation state is updated based on the state validity expressed including a difference between dimensional information of the reflection source projected onto the observation space in the estimation state and the observation information.
