Image-Based Wind Estimation for Flying Objects Without Separate Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wind estimation systems for flying objects require separate measurement units, which can be cumbersome and limit their effectiveness in recognizing wind conditions.
Innovation Solution
A wind estimation apparatus that utilizes a camera mounted on a moving body to acquire target images, estimating wind direction and strength by analyzing the trajectories of floating matters in the images, and using reference information to enhance accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a separate measurement unit is provided on a cable extending from the flight machine, then wind speed information can be acquired, but the device complexity increases and ease of operation deteriorates
Solution Approach 1:
The patent combines the wind measurement function with the flight machine itself by mounting a measurement unit on the flight machine. This integration eliminates the need for separate measurement units on cables, reducing device complexity while maintaining wind speed measurement capability. The measurement unit becomes part of the flight machine system rather than an external accessory.
Solution Approach 2:
The measurement unit mounted on the flight machine serves multiple functions: it measures wind speed for flight safety, provides data for flight control, and enables wind condition monitoring. This multi-functionality reduces the need for separate dedicated measurement systems, simplifying the overall device architecture.
2Measurement precision
If a separate measurement unit is provided on a cable extending from the flight machine, then wind speed information can be acquired, but ease of operation deteriorates
Solution Approach 1:
By integrating the measurement unit directly on the flight machine, the system becomes easier to operate. The unified design eliminates complex cable connections and separate unit management, allowing pilots to access and interpret wind data more conveniently through integrated displays and controls.
3Measurement precision
If wind measurement uses a separate measurement unit, then wind speed can be measured, but the system cannot easily recognize wind situations
Solution Approach 1:
The patent introduces a wind situation recognition system that acts as an intermediary between the measurement unit and the pilot. This system processes raw wind speed data and presents it in an easily interpretable format, such as visual displays showing wind direction, strength, and potential hazards, thereby improving wind situation recognition without requiring changes to the measurement capability itself.

AI summary
A wind estimation apparatus includes an acquisition unit and an estimation unit. The acquisition unit acquires a target image of a target region. The estimation unit estimates at least one of a direction and strength of wind in the target region by using the target image.
