Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for detecting Ethernet camera displacement are computationally intensive and prone to errors, and IMU data processing burdens the host machine, necessitating a more efficient and accurate solution.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If image processing techniques are used to identify changes in field of view, then displacement detection is achieved, but computational complexity increases and error susceptibility rises
Solution Approach 1:
The patent extracts the displacement detection function from complex image processing algorithms and implements it through a dedicated sensor (accelerometer/gyroscope) that directly measures displacement. This extraction principle removes the computational burden from the host machine while maintaining detection accuracy through specialized hardware.
Solution Approach 2:
The patent replaces the mechanical/optical image processing system with an electronic sensor-based measurement system. Instead of analyzing image changes through complex computations, the system uses accelerometer and gyroscope sensors to directly detect displacement, substituting mechanical/optical methods with electronic sensing.
2Loss of information
If IMU data is provided to host machine for processing, then displacement information is available, but processing load on host machine increases
Solution Approach 1:
The sensor module performs self-service by calculating displacement information locally and embedding it directly into RTCP reports. Instead of raw IMU data requiring host machine processing, the sensor autonomously computes displacement and delivers ready-to-use information, reducing the host machine's processing burden while ensuring information availability.
Solution Approach 2:
The patent applies preliminary action by pre-calculating displacement data at the sensor level before transmission to the host machine. The displacement computation is performed in advance during data capture, so when data reaches the host machine, it is already processed and ready for immediate use without additional computational burden.
3Adaptability or versatility
If coordinate data is embedded in RTCP report at protocol level, then standard applications can utilize displacement data, but protocol implementation complexity increases
Solution Approach 1:
The patent applies universality by embedding displacement data into the existing RTCP protocol structure, which is already widely supported by standard applications. This approach allows the same protocol to serve both its original function (quality of service monitoring) and the new function (displacement data transmission), ensuring broad application compatibility without requiring custom protocols.
Solution Approach 2:
The patent merges displacement data transmission with the existing RTCP reporting mechanism. Instead of creating a separate communication channel or protocol extension, the displacement information is combined with regular RTCP reports, utilizing the existing infrastructure for data transmission and reducing implementation complexity.
