Auxiliary Photographing Device for Dyskinesia Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for diagnosing dyskinesia, such as Parkinson's disease, using wearable sensors can lead to inaccurate results due to data distortion caused by the wearable devices affecting the patient's movements.
Innovation Solution
An auxiliary photographing device with a mechanical arm and camera assembly that adjusts its position to capture clear images of the target body part without the need for wearable devices, using a control method that includes determining the target region's position and adjusting the camera's orientation to ensure accurate data collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If wearable sensors are used to detect dyskinesia, then motion data can be acquired in real time, but the wearable device affects the patient's action and causes data distortion
Solution Approach 1:
The patent extracts the sensing function from the patient's body by using an external camera system instead of wearable sensors. The camera assembly captures motion data from a distance, eliminating the need for the patient to wear any devices that could interfere with natural movement and cause data distortion.
Solution Approach 2:
The patent introduces a camera assembly as an intermediary device to capture motion data. Instead of directly measuring motion through wearable sensors on the patient, the system uses the camera to record visual information, which is then processed to extract motion parameters, thereby avoiding direct contact with the patient.
2Object-affected harmful factors
If the camera assembly is positioned far from the target body part, then the patient's movement is not constrained, but the image quality and detail are reduced
Solution Approach 1:
The patent implements a movable mechanical arm that can dynamically adjust the camera assembly's position. The mechanical arm allows the camera to move closer to the target body part when needed for detailed imaging, while still maintaining the ability to capture unrestricted patient movement from various positions and angles throughout the examination process.
Solution Approach 2:
The camera assembly is designed to serve multiple functions: it can capture both wide-area motion data when positioned farther away and detailed close-up images when positioned closer. The system universally handles different imaging requirements by adjusting the camera's position through the mechanical arm, eliminating the need for separate devices for different imaging distances.

AI summary
The present disclosure relates to the field of artificial intelligence (AI) technologies, and provides an auxiliary photographing device for dyskinesia analysis, and a control method and apparatus for an auxiliary photographing device for dyskinesia analysis. The method includes controlling a camera assembly of the auxiliary photographing device at a first position to perform photographing, to obtain a first image, the first image comprising a target body part of a patient having dyskinesia; determining, in the first image, a position of a target region corresponding to the target body part; controlling an orientational movement of a mechanical arm of the auxiliary photographing device according to the position of the target region, to adjust the camera assembly to a second position; and controlling the camera assembly at the second position to perform photographing, to obtain a second image, the second image comprising the target body part.
