Aerial Stereo Imaging With Dynamic Baseline for Far-Distance Objects
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for shooting stereoscopic videos fail to produce a stereoscopic effect for far-distance objects due to a fixed baseline distance between cameras, limiting the immersive experience for viewers.
Innovation Solution
The method involves using multiple aerial vehicles to capture stereoscopic multimedia information from different angles, adjusting the baseline distance dynamically based on the object distance and environment, and employing collaborative jitter-prevention and focal length adjustment techniques to ensure consistent and stereoscopic image capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a binocular camera with normal pupil distance is used to shoot stereoscopic videos, then close-shot videos can be captured with good stereoscopic effect, but far-distance objects do not show any stereoscopic effect
Solution Approach 1:
The patent makes the baseline distance dynamic by using multiple aerial vehicles that can adjust their relative positions. The system transitions from a fixed baseline (normal pupil distance) to a variable baseline that can be extended to hundreds of meters, allowing the stereoscopic system to adapt to different shooting distances and scenarios.
Solution Approach 2:
The patent extends the baseline distance from the traditional horizontal dimension (pupil distance of a few centimeters) to the spatial dimension by distributing cameras across multiple aerial vehicles. This dimensional expansion enables far-distance objects to exhibit stereoscopic effects by creating sufficient parallax through large baseline separation.
2Manufacturing precision
If multiple aerial vehicles are used to increase baseline distance for far-distance shooting, then stereoscopic effect is improved, but system complexity and coordination difficulty increase
Solution Approach 1:
The patent merges multiple aerial vehicles into a coordinated stereoscopic shooting system. By combining the capabilities of multiple vehicles and synchronizing their operations, the system achieves a functional equivalent to a single complex stereoscopic platform while distributing the operational complexity across multiple independent units.
Solution Approach 2:
The system implements feedback mechanisms through real-time communication between aerial vehicles and the ground control server. The server receives position information from GPS modules and adjusts shooting parameters dynamically, creating a closed-loop control system that manages the complexity of multiple moving platforms through continuous monitoring and adjustment.
3Adaptability or versatility
If aerial vehicles move during shooting to adjust baseline distance, then adaptability to different scenarios is improved, but image jitter and stability problems occur
Solution Approach 1:
The system performs preliminary actions by pre-planning shooting trajectories and baseline distances before actual capture. The ground control server calculates optimal paths and positions in advance, allowing aerial vehicles to execute predetermined stable trajectories that minimize jitter while achieving the desired baseline configuration for stereoscopic shooting.
Solution Approach 2:
The ground control server acts as an intermediary that coordinates between the moving aerial vehicles and the stereoscopic shooting requirements. It processes position data from GPS modules, determines optimal shooting parameters, and sends control instructions to maintain image stability while achieving the desired baseline distance for far-distance objects.

AI summary
Disclosed is a method, device and system for determining stereoscopic multimedia information. The method includes: acquiring multimedia information collected by respective multimedia collection apparatuses of two or more aerial vehicles; and, determining corresponding stereoscopic multimedia information according to the acquired multimedia information. In the present disclosure, a same object is shot by respective loaded multimedia collection apparatuses of two or more aerial vehicles at different angles. In comparison with conventionally shooting a same object by a single unmanned aerial vehicle at a same angle, more stereoscopic multimedia information may be obtained, and a user is more likely to feel the stereoscopic impression of the multimedia information when viewing the multimedia information. In this way, both the visual enjoyment of the user and the user experience are improved.
