Multi-Camera Aerial Imaging with Wide and Telephoto Lenses
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aerial vehicles equipped with normal lenses for aerial photography face limitations in capturing small targets due to limited image sensor resolution and narrow perspective, making it difficult to simultaneously photograph both large and small-perspective scenes effectively.
Innovation Solution
A multi-camera photographing apparatus with a first lens module and a second lens module, where the second lens module captures images with a higher pixel count, allowing for image processing to combine the perspectives, including optical axis adjustment and registration analysis to generate an output image that overlays or replaces areas in the first image with the second image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a zoom lens is used to photograph small targets with high resolution, then the imaging precision is improved, but the device weight increases and flight performance deteriorates
Solution Approach 1:
The patent divides the imaging system into multiple independent lens modules (first lens module for wide-angle scene capture, second lens module for telephoto target capture) instead of using a single heavy zoom lens. Each module has a fixed focal length and is optimized for specific imaging scenarios, thereby achieving high imaging precision for small targets without requiring a heavy zoom mechanism.
Solution Approach 2:
The multi-camera photographing apparatus provides multiple imaging functions through different lens modules. The first lens module captures wide-angle scenes while the second lens module captures detailed views of small targets. This multi-functional system replaces the need for a single zoom lens that would require significant weight to achieve the same versatility.
2Device complexity
If a normal lens with fixed focus is used, then the device complexity is reduced, but the adaptability to different shooting scenarios deteriorates
Solution Approach 1:
The system segments the imaging task into two distinct functions handled by separate lens modules: wide-angle scene capture and telephoto target capture. Each module maintains simple fixed-focus optics, avoiding the complexity of zoom mechanisms while collectively providing adaptability to different shooting scenarios through image processing integration.
Solution Approach 2:
The patent combines multiple fixed-focus lens modules with different fields of view into a unified photographing system. By merging the capabilities of wide-angle and telephoto lenses and integrating their images through processing, the system achieves scenario adaptability equivalent to a zoom lens while maintaining the simplicity and reliability of fixed-focus optics.
3Device complexity
If a single lens module is used, then the device structure is simplified, but the ability to capture both large-perspective and small-perspective scenes simultaneously deteriorates
Solution Approach 1:
The patent segments the imaging function into multiple specialized lens modules: a first lens module for large-perspective scene capture and a second lens module for small-perspective target capture. This segmentation allows each module to be optimized for its specific function while the integrated system achieves multi-perspective capture capability that a single lens module cannot provide.
Solution Approach 2:
The system adds a dimensional aspect to image capture by incorporating multiple lens modules with different fields of view and focal characteristics. This multi-dimensional approach enables simultaneous capture of both wide scenes and detailed targets, transforming a single-perspective limitation into a multi-perspective capability through spatial and optical dimension diversification.

AI summary
The present application discloses a method for processing an image, an image processing apparatus, a multi-camera photographing apparatus and an aerial vehicle. A first image photographed by a first lens module is obtained, the first image including a target object; then a second image photographed by a second lens module is obtained; and image processing is performed on the first image and the second image, and an output image is generated, so that a range in a large-perspective scene and precision of the target object in a small-perspective scene can be both combined.
