Problems solved by technology

With the single-camera shooting method, due to the constraints of the camera's field of view, it is difficult to take into account the details of the captured image and the requirements of the field of view; while the traditional ground-mounted camera shooting method is the so-called "land-based" platform shooting method , due to the low shooting angle, the distance and field of view that can be shot are also extremely limited. If you need to shoot and record typical events, it is difficult to determine and control the attitude of the shooting camera in this case

Embodiment Construction

[0039] "Large scene photography" refers to the shooting situation when the distance between the camera and the object to be photographed is between 1 kilometer and 3 kilometers, and the field of view is required to be in the range of tens of meters to hundreds of meters.

[0040] Such as figure 1As shown, the space-based large-scene camera system of the present invention includes a multi-rotor drone group subsystem, a multi-rotor drone flight ground control subsystem, and a ground image data processing and display terminal subsystem, wherein:

[0041] The multi-rotor UAV sub-system consists of multiple multi-rotor UAVs, micro-pressure difference wind speed and direction sensors, two-degree-of-freedom rotary motion long-focus camera, GPS timing module, and air wireless data transceiver terminal; each multi-rotor UAV A two-degree-of-freedom rotary motion long-focus camera, a GPS timing module, and an air wireless data transceiver terminal are installed on the aircraft; the multi...

Abstract

The invention discloses an air-based large-scene photographing system and method. The system is composed of a multi-rotor unmanned machine set subsystem, a multi-rotor unmanned machine flight ground control subsystem and a ground image data processing and display terminal subsystem. According to the air-based large-scene photographing system and method, multiple multi-rotor unmanned machines are controlled to conduct the formation flight by additionally hanging cameras below the multi-rotor unmanned machines, the reasonable position layout of multiple aircrafts is achieved in space near the ground, and images photographed by the unmanned machines are sent back to the ground in real time; the ground image data processing and display terminal subsystem receives the image data, projection converting and splicing processing are conducted on the images photographed by the multi-rotor unmanned machines through an image analyzing and machine vision technology, and finally two-dimensional splicing on remote large-scene scenes is formed. The system is suitable for rebuilding of large scenes and observing and measuring of points of impact when various military exercises and target practicing and shooting are conducted.

Description

technical field [0001] The invention relates to a space-based large scene camera system and method. Background technique [0002] When carrying out various military exercises and target shooting tests of weapon systems, it is necessary to use photography to record the situation and key events of the exercise in order to realize post-event analysis and processing. With the single-camera shooting method, due to the constraints of the camera's field of view, it is difficult to take into account the details of the captured image and the requirements of the field of view; while the traditional ground-mounted camera shooting method is the so-called "land-based" platform shooting method , due to the low shooting angle, the distance and field of view that can be shot are also extremely limited. If you need to shoot and record typical events, it is difficult to determine and control the attitude of the shooting camera in this case. Contents of the invention [0003] Aiming at the ...
