Image Capturing Apparatus Frequency Control for Drone Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controlling the position and attitude of an image capturing apparatus mounted on a moving device, such as a drone, face accuracy issues due to insufficient update frequency of additional information, leading to difficulties in tracking subjects, especially when they move away from the center of the view.
Innovation Solution
The image capturing apparatus adjusts its image capturing frequency based on a transmission setting, generating and transmitting additional information at higher frequencies when necessary to improve control accuracy, allowing for precise positioning and attitude control by the control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If additional information is transmitted at a lower update frequency, then transmission load and processing requirements are reduced, but control accuracy decreases and the image capturing apparatus cannot quickly track subject movement
Solution Approach 1:
The patent applies dynamics by making the image capturing frequency adjustable based on transmission settings. The system transitions from a fixed low update frequency to a variable frequency that can increase to higher levels when needed, allowing the system to adapt its performance characteristics to different operational requirements and resolve the contradiction between control accuracy and update frequency.
Solution Approach 2:
The patent changes the parameter of image capturing frequency based on transmission settings. By allowing the frequency to vary between different levels (first, second, and third settings), the system can optimize control accuracy when needed while maintaining lower resource consumption during normal operation, thus resolving the contradiction between measurement precision and productivity.
2Measurement precision
If image capturing frequency is increased to improve tracking accuracy, then subject tracking capability improves, but data transmission volume and processing load increase
Solution Approach 1:
The system dynamically adjusts the image capturing frequency based on transmission settings rather than operating at a constant high frequency. This allows the system to maintain high tracking accuracy when needed (first setting) while reducing data volume during normal operation (second setting), resolving the contradiction between tracking accuracy and data quantity.
Solution Approach 2:
The patent implements periodic action by establishing different image capturing frequencies corresponding to different transmission settings. The system alternates between these periodic capture cycles based on operational needs, allowing high-accuracy tracking during critical moments while maintaining lower data throughput during stable conditions.
3Measurement precision
If additional information is transmitted frequently, then control accuracy improves, but transmission bandwidth and system complexity increase
Solution Approach 1:
The patent applies dynamics by making the transmission frequency of additional information variable rather than fixed. The system can increase transmission frequency to improve control accuracy when needed (first setting) while maintaining lower complexity during normal operation (second setting), thus resolving the contradiction between measurement precision and device complexity.
Solution Approach 2:
The system changes the transmission parameter of additional information frequency based on transmission settings. By implementing multiple frequency levels, the system can optimize control accuracy when required while avoiding excessive transmission complexity during routine operation, effectively resolving the contradiction between precision and complexity.

AI summary
There is provided an image capturing apparatus. An image capturing unit captures an image at an image capturing frequency that depends on a transmission setting. In a case where the transmission setting is a first setting, the image capturing frequency is higher than in a case where the transmission setting is a second setting or a third setting. A generation unit generates additional information associated with a captured image obtained by capturing an image at the image capturing frequency in the case where the transmission setting is the first setting or the third setting. The additional information is for use in control processing for a control device to control at least one of position and attitude of the image capturing apparatus.
