Adaptive Gimbal Response Speed for Smooth Target Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Gimbal systems face challenges in smoothly following targets with varying speeds, often resulting in stiff images when following fast-moving targets and loss of target when following slow-moving targets due to inadequate speed configuration.
Innovation Solution
A control method and controller that determine the acceleration of the gimbal base and adjust the movement response speed of the gimbal to match the attitude of the camera, using inertial measurement units to measure angular velocity and acceleration, allowing for intelligent control of the gimbal's movement response speed based on the base's acceleration and camera's angular velocity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the gimbal speed is configured to be fast, then the gimbal can quickly follow fast-moving targets, but the captured images become stiff and less smooth
Solution Approach 1:
The patent implements dynamic speed adjustment by making the gimbal's following speed variable rather than fixed. The controller dynamically changes the speed parameter based on real-time detection of target motion characteristics, allowing the system to adapt between fast following (for moving targets) and slow following (for static targets) to resolve the contradiction between speed and image smoothness
Solution Approach 2:
The patent changes the speed parameter of the gimbal based on detected target motion state. By detecting whether the target is moving or static and adjusting the following speed parameter accordingly, the system optimizes both the responsiveness to targets and the smoothness of captured images
2Stability of the object's composition
If the gimbal speed is configured to be slow, then the captured images are smoother, but the gimbal cannot handle sudden acceleration and loses the target
Solution Approach 1:
The patent employs feedback control by continuously detecting the target's motion state and using this information to adjust the gimbal's following speed. The controller receives feedback about target acceleration and motion characteristics, then dynamically adjusts the speed parameter to maintain both smooth imaging and target tracking capability
Solution Approach 2:
The system transitions from a static speed configuration to a dynamic one where the following speed adapts in real-time based on target motion. This dynamic adjustment allows the gimbal to provide slow following for smooth images when targets are static, and fast response when targets accelerate suddenly
3Device complexity
If a fixed speed configuration is used, then the control system is simple, but it cannot adapt to targets with varying speeds
Solution Approach 1:
The patent implements self-service control where the gimbal system automatically detects target motion characteristics and adjusts its own following speed without external intervention. The controller autonomously determines the appropriate speed parameter based on detected target state, eliminating the need for manual configuration and enabling adaptation to varying target speeds
Solution Approach 2:
The patent creates a universal control system that can handle multiple types of targets (static, slow-moving, fast-moving, accelerating) using a single adaptive control mechanism. By detecting target motion state and adjusting speed accordingly, the system becomes versatile enough to handle various shooting scenarios without requiring different fixed configurations
