AdjustSense: Adaptive 3D Sensing System with Adjustable Spatio-Temporal Resolution and Measurement Range Using...

Area of Science:

• Robotics and Automation
• Computer Vision
• Sensor Technology

Background:

• Conventional 3D sensing devices have fixed spatio-temporal resolution and measurement range, limiting their adaptability to diverse tasks.
• Existing systems struggle with simultaneous multi-target 3D sensing due to these constant parameters, and integrating multiple systems is often impractical.

Purpose of the Study:

• To propose a novel, single 3D sensing system capable of adaptively adjusting its spatio-temporal resolution and measurement range.
• To enable seamless switching between multiple 3D sensing tasks using a single, integrated system.
• To achieve low-latency visual feedback for real-time adaptive adjustments.

Main Methods:

• Development of an adaptive 3D sensing system named AdjustSense.
• Integration of a high-speed camera (sensor) and a direct drive motor (actuator) for rapid adjustments.
• Implementation of a low-latency visual feedback loop to control adaptive parameter changes.

Main Results:

• Demonstrated AdjustSense's ability to adapt to changing target positions.
• Quantitatively evaluated the system's spatio-temporal resolution and measurement range.
• Successfully performed multiple 3D sensing tasks, including 360° sensing, high-resolution multi-target sensing, and high spatio-temporal resolution local sensing.

Conclusions:

• AdjustSense offers a versatile solution for complex 3D sensing challenges.
• The adaptive nature of AdjustSense overcomes limitations of conventional fixed-parameter systems.
• This system facilitates simultaneous execution of diverse 3D sensing tasks, enhancing efficiency and capability.
