Dual-Gimbal Image Shooting for Stable Mobile Composite Capture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image shooting devices require fixed, stable setups, often using tripods, which hinder mobility and complicate shooting scenarios like light painting and panorama photography.
Innovation Solution
Employing a dual-gimbal system with a first camera mounted on a free gimbal and a second camera on a fixed gimbal, where the free gimbal maintains the first camera's position and the fixed gimbal allows the second camera to move, enabling composite image creation from multiple frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a tripod is used to stabilize the shooting device, then image stability is improved, but shooting mobility and ease of operation deteriorate
Solution Approach 1:
The system divides the stabilization function into two independent gimbals: a first gimbal for stabilizing the shooting direction and a second gimbal for stabilizing the device body. This segmentation allows each gimbal to handle specific stabilization tasks independently, eliminating the need for a tripod while maintaining image stability during mobile shooting.
Solution Approach 2:
The system transitions from static tripod-based stabilization to dynamic gimbal-based stabilization. The gimbals actively adjust and compensate for device movement in real-time during shooting, enabling stability during mobile operations rather than requiring a fixed stationary setup.
2Reliability
If the shooting device is kept stationary for long exposure shooting, then image quality is improved, but shooting flexibility and adaptability deteriorate
Solution Approach 1:
The gimbals enable the device to maintain stability during movement, allowing long exposure shooting while the device is in motion rather than requiring it to be stationary. This dynamic stabilization capability provides flexibility for various shooting scenarios including moving subjects and panoramic shots.
Solution Approach 2:
The dual-gimbal system provides multiple functions: stabilizing the shooting direction, stabilizing the device body, and enabling both stationary and mobile shooting modes. This multi-functionality allows the device to adapt to various shooting scenarios while maintaining image quality.
3Stability of the object's composition
If additional stabilization equipment like a tripod is used, then image stability is improved, but device complexity and setup requirements worsen
Solution Approach 1:
The system merges the stabilization function into the camera device itself through integrated gimbals, rather than requiring separate external equipment like tripods. This integration eliminates additional setup requirements while maintaining image stability.
Solution Approach 2:
The gimbals serve multiple purposes within the device: stabilizing shooting direction, stabilizing the device body, and enabling mobile shooting. This multi-functionality reduces the need for additional specialized equipment, simplifying the overall system setup.

AI summary
An image shooting method and apparatus, an electronic device, and a readable storage medium and pertains to the field of image processing. The specific implementation includes receiving a first input for triggering image shooting; obtaining, in response to the first input, multiple frames of first images shot by the first camera and multiple frames of second images shot by the second camera, where in an image shooting process, the free gimbal controls an actual shooting position of the first camera to remain unchanged, and the fixed gimbal controls the second camera to move along with the electronic device; and compositing the multiple frames of first images and the multiple frames of second images to obtain a composite image.
