Transportable Sensor Localization With Pose-Based Sensor Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current localization technologies in devices with multiple sensors, such as RGB and depth cameras, consume excessive energy and perform poorly in varying environmental conditions, leading to inefficient resource usage and potential degradation in localization accuracy.
Innovation Solution
A device is configured to activate and deactivate sensors based on specific localization performance rules, transitioning between sensors at optimal poses to maintain accurate localization while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all sensors are always turned on, then localization performance is maintained, but energy consumption increases
Solution Approach 1:
The patent applies dynamics by making sensor activation dynamic rather than static. The system determines device poses and evaluates sensor performance rules to dynamically activate or deactivate sensors based on current environmental conditions and localization requirements, transitioning from a static 'all sensors on' approach to a dynamic selective activation model that balances performance and energy consumption
Solution Approach 2:
The patent changes the parameter of sensor activation state based on pose information and performance rules. By evaluating whether current device poses satisfy localization performance rules, the system changes sensor activation parameters (on/off states) to optimize energy consumption while maintaining acceptable localization performance
2Measurement precision
If multiple sensors are used, then localization accuracy improves, but device complexity increases
Solution Approach 1:
The patent segments sensor management by separating the localization function from sensor activation control. The processor independently determines device poses using available sensor data and separately evaluates performance rules to control sensor activation, dividing the complex sensor management task into manageable segments that reduce overall system complexity
Solution Approach 2:
The system implements self-service by having the device autonomously determine its own poses and evaluate performance rules to control sensor activation without external intervention. The processor self-manages sensor activation based on internal pose data and stored performance criteria, reducing the need for complex external control mechanisms

AI summary
A device is configured for performing localization using a set of sensors that are transportable with the device. The device includes at least one processor operationally connected to the set of sensors, and at least one memory that stores program code. The program code configures the at least one processor to determine a first set of device poses where a first sensor satisfies a localization performance rule, and to determine a second set of device poses where a second sensor satisfies the localization performance rule. The at least one processor is further configured to activate the second sensor while the first sensor is active based on a pose of the device transitioning from not being within to being within the second set of device poses.
