Multi-source imaging load for unmanned aerial vehicle

Abstract

The invention discloses a multi-source imaging load for an unmanned aerial vehicle. The multi-source imaging load comprises a visible light imaging module, an infrared imaging module, a laser indication module, a central processing module, a target detection module and a video compression module, wherein the central processing module directly controls the laser indication module, acquires video data from the visible light imaging module and the infrared imaging module, sends the video data with the native resolution to the video compression module after converting the video data into data in the same data format, sends down-sampled video data to the target detection module, and outputs compressed video data returned by the video compression module and target coordinate data returned by the target detection module to an external interface. The load has the advantages of small size, low weight, strong function and the like and can fully meet requirements of day-and-night photoelectric detection at middle and close distances, and convenience can be brought to usage under different environment and application conditions through matched usage of multiple loads.

Description

technical field [0001] The invention relates to a multi-source imaging payload for an unmanned aerial vehicle. Background technique [0002] UAVs are more and more widely used in film and television, search and rescue, police, military and other fields. Small UAVs are popular with users for their low cost, simple use and powerful functions. As the key equipment of the UAV, the photoelectric imaging load undertakes the work of the UAV's ground reconnaissance, target search, tracking, positioning, etc., and is one of the core loads of the UAV. With the development of technology, the production and development of UAVs have gradually realized modularization, processization and batching, but there is no unified standard for the design of UAV payloads. As the key components of UAV payload, the optical imaging payload and image processing module is the module with the most difficult design, the highest cost and the most complex functions in UAV payload design. [0003] Due to the...

Problems solved by technology

[0003] Due to the complex hardware interface and data format standards of imaging equipment, UAV payloads often need to design different interfaces and switching circuits for different imaging equipment, resulting in increased payload volume and increased energy consumption; in order to ensure the video data path of multi-source imaging payloads Choice, the real-time video switching method needs to implement redundant data links internally to transmit multiple video data at the same time, resulting in a large circuit design size, while the non-real-time video switching method needs to be hot-started when the load is powered on, resulting in the load The air is out of control; in order to enrich the function design of the photoelectric load, it is usually chosen to add a new module to the load for each new function, resulting in high design costs; the external interface design of the traditional load is relatively single, and the data format is not uniform. It is difficult to change after being finalized, and it is even more difficult to adapt to changing external interface requirements, resulting in the need for repeated development of each new interface, resulting in a lot of repeated design and labor

Such problems lead to high overall cost of drones, which greatly limits the promotion and use of drones in many fields
