IoT Volumetric Camera Switching for Subject-Aware Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current volumetric capture systems face inefficiencies due to volumetric arrays capturing large areas where only a few devices are pointed at the subject, leading to unnecessary footage capture, increased power consumption, data processing, and rendering costs.
Innovation Solution
A system that dynamically activates and de-activates volumetric capture devices using IoT-based cameras by constructing a graph data structure representing device network topology, detecting subject location, and switching devices between recording and standby states based on their capture range.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all volumetric devices in the array are kept in recording state to ensure continuous subject capture, then the reliability of subject capture is improved, but the power consumption and data processing costs increase
Solution Approach 1:
The system dynamically adjusts the operational state of volumetric devices based on real-time subject detection. Devices transition between recording state, standby state, and active state according to whether the subject is within their capture range, optimizing power consumption while maintaining capture reliability
Solution Approach 2:
The system implements feedback mechanisms where detection results from volumetric devices inform the state management module. When no subject is detected in a device's capture range, the device transitions to standby or active state, reducing power consumption while maintaining system readiness to capture the subject when it enters the range
2Reliability
If all volumetric devices continuously record to ensure no subject data is lost, then the completeness of volumetric data is improved, but the data processing and rendering costs increase
Solution Approach 1:
The system dynamically controls data recording based on subject presence. Devices in standby state do not continuously record, reducing data generation and processing costs. When the subject enters the capture range, devices transition to recording state to ensure complete volumetric data capture
Solution Approach 2:
Different devices in the volumetric array operate in different states (recording, standby, or active) based on their specific capture range and subject proximity. This localized state management reduces overall data processing requirements while maintaining data completeness for the captured subject
3Use of energy by moving object
If devices are switched to standby state when subject is out of range to reduce power consumption, then the power efficiency is improved, but the response time to capture subject when entering range increases
Solution Approach 1:
Devices in standby state maintain preliminary readiness to transition to recording or active state. The system pre-configures devices so that when the subject enters the capture range, the transition to active recording state occurs rapidly, minimizing response time while maintaining power efficiency during periods when no subject is present
