Gimbal Camera Imaging for Remote OCR Input
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable computing apparatuses have limited input and output capabilities due to fixed camera and microphone orientations, requiring manual adjustment for image and sound capture, and restricted display interaction, limiting their ability to dynamically receive and process images and sounds.
Innovation Solution
A method involving a computing apparatus with a gimbal-interlocked imaging device that controls the camera's rotation for dynamic image capture and uses object analysis and OCR models to recognize and track objects, enabling remote input and output of characters and spatial information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a camera is mounted on a portable computing apparatus with fixed orientation, then the device structure is simple, but the field of view is limited and manual adjustment is required
Solution Approach 1:
The patent applies the dynamics principle by implementing a gimbal mechanism that enables the camera to rotate and adjust its orientation dynamically. The gimbal allows the imaging device to change its viewing direction in real-time, transforming the fixed camera system into a dynamic one that can adapt to different fields of view without requiring complete structural redesign of the portable device.
Solution Approach 2:
The patent segments the imaging system from the main portable device body by introducing an independent gimbal module. This segmentation allows the camera subsystem to be controlled separately, enabling remote operation and independent adjustment of the camera's orientation while keeping the main device structure simple.
2Ease of operation
If a touch display is attached to the portable terminal, then output information is provided, but user interaction is limited to local contact input
Solution Approach 1:
The patent replaces the mechanical contact-based input system with a vision-based remote input system. By using the camera to capture images and OCR technology to recognize text, the system substitutes physical keyboard or touch input with remote optical recognition, enabling users to input text from a distance without direct contact with the device.
Solution Approach 2:
The patent introduces an intermediary system consisting of the camera and OCR processing that mediates between the user and the device. Instead of direct contact input, the user's text is captured remotely by the camera, processed by the OCR module, and then input to the device, creating a new interaction pathway that enhances ease of operation.
3Measurement precision
If object analysis and OCR processing are performed on captured images, then character recognition accuracy is improved, but processing time increases
Solution Approach 1:
The patent applies preliminary action by performing object analysis first to identify and locate text regions in the captured image before executing OCR processing. This pre-processing step allows the system to focus OCR resources only on relevant areas containing text, rather than processing the entire image, thereby reducing overall processing time while maintaining high character recognition accuracy.
