OBJECT TRACKING DEVICE, OBJECT TRACKING METHOD, AND RECORDING MEDIUM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18033425 titled 'OBJECT TRACKING DEVICE, OBJECT TRACKING METHOD, AND RECORDING MEDIUM
Simplified Explanation
The abstract describes an object tracking device that extracts target candidates from a series of images and tracks them using a confidence level indicating similarity with a target model. The device also updates the search range and target model based on frame and movement information.
- The object tracking device extracts target candidates from a series of images.
- It updates the search range based on frame information of a target in a previous image and movement information of the target.
- The device searches for and tracks the target using a confidence level indicating similarity with a target model.
- It updates the target model using the extracted target candidates.
Potential Applications
- Surveillance systems: The object tracking device can be used in surveillance systems to track and monitor specific objects or individuals.
- Robotics: It can be applied in robotics to track and follow objects or people in real-time.
- Augmented reality: The device can assist in augmented reality applications by accurately tracking and overlaying virtual objects onto the real world.
Problems Solved
- Efficient object tracking: The device solves the problem of accurately tracking objects in a series of images by extracting target candidates and updating the search range.
- Model adaptation: It addresses the issue of maintaining an up-to-date target model by updating it using the extracted target candidates.
Benefits
- Accurate tracking: The device improves the accuracy of object tracking by considering frame and movement information.
- Real-time tracking: It enables real-time tracking of objects, making it suitable for applications that require immediate response.
- Adaptability: The device can adapt to changes in the target's appearance or movement by updating the target model.
Original Abstract Submitted
In an object tracking device, an extraction means extracts target candidates from time series images. A search range update means updates a search range based on frame information of a target in a previous image in a time series and movement information of the target. A tracking means searches for and tracks the target using a confidence level indicating similarity with a target model, from among the target candidates extracted in the search range. A model update means updates the target model using the target candidates extracted in the search range.
