RELOCALIZATION FOR DEVICE FINDING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18080730 titled 'RELOCALIZATION FOR DEVICE FINDING
Simplified Explanation
The abstract describes a method for determining the location of a second electronic device based on the distance and pose of a first electronic device. Here are the key points:
- The method involves determining the distance between the first and second electronic devices at different positions along a trajectory.
- The pose of the first electronic device with respect to a reference coordinate system is also determined.
- An anchor point is set and stored for each position, representing the range value and pose of the first electronic device.
- Updates to the anchor point set for the current position are received and used to update the corresponding pose.
- The location of the second electronic device is estimated based on the range values and poses of the anchor points.
Potential applications of this technology:
- Indoor positioning systems: This method can be used to accurately locate electronic devices within a confined space, such as a building or a room.
- Augmented reality: By accurately determining the location of a second electronic device, this method can enhance augmented reality experiences by overlaying virtual objects onto the real world.
- Asset tracking: This technology can be used to track the location of valuable assets within a defined area, such as in a warehouse or a manufacturing facility.
Problems solved by this technology:
- Accurate positioning: The method provides a way to accurately determine the location of electronic devices, which can be useful in various applications where precise positioning is required.
- Robustness: By using multiple anchor points along a trajectory, the method can handle variations in distance and pose, improving the robustness of the location estimation.
Benefits of this technology:
- Improved accuracy: By considering both distance and pose, the method can provide more accurate location estimates compared to methods that only rely on distance measurements.
- Real-time tracking: The method allows for real-time updates to the anchor points, enabling continuous tracking of the second electronic device's location.
- Scalability: The method can be applied to a large number of positions along a trajectory, making it suitable for tracking devices in various scenarios.
Original Abstract Submitted
A method is provided that includes at each position of a plurality of positions along a trajectory of a first electronic device within an area: determining a range value corresponding to a distance between the first electronic device and a second electronic device, determining a pose of the first electronic device with respect to a reference coordinate system, and setting and storing an anchor point corresponding to the determined range value and pose. An update to an anchor point set for a current position of the first electronic device is received and the determined pose corresponding to one or more of the set anchor points is updated based on the update to the anchor point set for the current position of the first electronic device. A location of the second electronic device is estimated based on the range values and poses corresponding to the set anchor points.
