USER EQUIPMENT SENSOR CALIBRATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17997290 titled 'USER EQUIPMENT SENSOR CALIBRATION
Simplified Explanation
The patent application describes a method for determining sensor calibration parameters for a sensor in a user equipment. The method involves obtaining multiple sets of sensor measurement values in a sensor coordinate system and determining the calibration parameters based on subsets of these measurement values.
- The method involves obtaining multiple sets of sensor measurement values in a sensor coordinate system.
- The calibration parameters are determined based on subsets of the measurement values.
- The subsets used for calibration include measurement values taken when the user equipment is at rest and when it is in motion.
- The calibrated sensor measurement values are obtained by applying the calibration parameters to a selected set of measurement values in a reference coordinate system.
Potential Applications
This technology can have various applications in fields such as:
- Robotics: Calibrating sensors in robots to improve accuracy and reliability of measurements.
- Virtual Reality/Augmented Reality: Enhancing the precision of motion tracking sensors for immersive experiences.
- Autonomous Vehicles: Improving the calibration of sensors used for navigation and obstacle detection.
- Sports and Fitness: Enhancing the accuracy of wearable sensors for tracking movements and performance.
Problems Solved
The method described in the patent application solves the following problems:
- Sensor Inaccuracy: By calibrating the sensor measurement values, the accuracy of the sensor can be improved.
- Coordinate System Alignment: The calibration parameters allow for the transformation of sensor measurements from the sensor coordinate system to a reference coordinate system, ensuring consistency and compatibility with other systems.
- Motion Distortion: By considering both rest and motion states, the method accounts for any distortions in sensor measurements caused by movement.

Original Abstract Submitted
A method for determining sensor calibration parameters includes: obtaining a plurality of sets of sensor measurement values, in a sensor coordinate system, of a sensor of a user equipment; and determining the sensor calibration parameters, based on a first portion of the plurality of sets of sensor measurement values corresponding to first times at which the user equipment is at rest and based on a second portion of the plurality of sets of sensor measurement values at least some of which correspond to second times at which the user equipment is in motion, such that application of the sensor calibration parameters to a selected set of the plurality of sets of sensor measurement values yields a calibrated set of calibrated sensor measurement values in a reference coordinate system.
