Remote Control Device for Imaging Target Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In imaging systems, the image-capturing person operating a portable terminal to control a remote pan head cannot easily focus on changes in the scene, leading to the possibility of missing desirable moments, as they cannot concentrate on the scene while operating the device.
Innovation Solution
A remote control device equipped with a distance measurement unit, motion sensor unit, and communication unit that measures and transmits imaging target position information to a control target device, allowing for automatic adjustment of the imaging direction and focus to ensure the target is captured, with a display unit for real-time image feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the image-capturing person operates the portable terminal to control the remote pan head, then the imaging device can be controlled remotely, but the image-capturing person cannot grasp the change of scene and may miss desirable moments
Solution Approach 1:
The patent implements a feedback mechanism where the portable terminal displays the captured image from the imaging device in real-time. This allows the image-capturing person to see the scene changes on the display unit while operating the remote control, providing visual feedback that resolves the contradiction between remote operation capability and scene awareness.
2Ease of operation
If the image-capturing person operates the portable terminal, then remote control is enabled, but the person cannot concentrate on watching the event
Solution Approach 1:
The system implements self-service functionality where the imaging device automatically captures images based on its own detection capabilities (motion detection, distance measurement) and the pre-set control parameters. This reduces the need for continuous manual operation, allowing the image-capturing person to focus on the event while the system serves itself by automatically adjusting and capturing.
3Measurement precision
If manual operation of portable terminal is required, then control precision can be maintained, but the complexity of operation increases
Solution Approach 1:
The patent implements preliminary action by pre-setting control parameters and automatic control rules before the imaging event. The imaging device is configured with motion detection thresholds, distance measurement parameters, and automatic pan-tilt-zoom control algorithms in advance. During operation, the system executes these pre-programmed instructions, reducing the need for complex real-time manual adjustments while maintaining precision.

Function Achieved in This Case
Enables the image-capturing person to easily and effectively capture images of the intended target by automatically adjusting the imaging direction and focus, ensuring that desirable scenes are not missed, and allowing the person to concentrate on the event rather than device operation.
Implementation Method 1

AI summary
A remote control device 60 measures a distance to a noticed imaging target OB directly in front of the remote control device 60 by a distance measurement unit. Further, the remote control device 60 measures a movement from an initial state by a motion sensor unit and transmits imaging target position information indicative of the measured distance and movement from a communication unit to an imaging device 20. An imaging target position calculation unit provided on the imaging device 20 calculates, on the basis of the imaging target position information from the remote control device 60, a direction of the noticed imaging target OB with respect to the direction in the initial state of the imaging device 20. By generating a direction controlling signal on the basis of a calculation result of the imaging target position calculation unit and outputting the direction controlling signal to a pan head 40, the imaging direction of the imaging device 20 can be set to the direction of the noticed imaging target OB.
