A light and small UAV multi-spectral remote sensing image acquisition device

Abstract

The invention discloses a light and small unmanned aerial vehicle multi-spectral remote sensing image acquisition device, which includes a main body of the unmanned aerial vehicle, and the main body of the unmanned aerial vehicle includes four driving components fixedly connected around the main body of the unmanned aerial vehicle. The inside of the main body is provided with a power supply battery and a control main board, and the power supply battery provides power for the control main board and the drive assembly; the surface of the control main board is provided with a wireless transmission chip. The light and small UAV multi-spectral remote sensing image acquisition device can replace the filters of different spectral bands by setting the replacement hole, and can drive the filters of different spectral bands to move between the multi-spectral sensor and the photographic lens by setting the servo motor , use electromagnet energization to fix the filter mounting frame, so that its position is fixed, so that the device can replace the filters of different spectral bands by controlling the servo motor and electromagnet as needed in high altitude, without landing operation , which improves the image acquisition efficiency.

Description

technical field [0001] The invention relates to the technical field of image acquisition, in particular to a multi-spectral remote sensing image acquisition device for a light and small unmanned aerial vehicle. Background technique [0002] Light and small drones refer to drones whose overall mass is greater than 7kg and less than 116kg. At present, most of the multi-spectral image acquisition devices used for UAVs are composed of two or more lenses, and are carried by larger UAVs or UAVs that can carry more weight. It is not suitable for light and small unmanned aerial vehicle flight platforms, so there is a shortage of civilian low-altitude multi-spectral remote sensing image acquisition devices composed of light and small electric drive unmanned aerial vehicles. [0003] At the same time, when multi-spectral imaging is performed, multiple sets of lenses lead to a larger body size and weight, and the overall energy consumption is more when the operation is empty. The filt...

It is not suitable for light and small UAV flight platforms, so there is a shortage of civilian low-altitude multi-spectral remote sensing image acquisition devices composed of light and small electric drive UAVs

[0003] At the same time, when multi-spectral imaging is performed, multiple sets of lenses lead to a larger body size and weight, and the overall energy consumption is more when the operation is empty. The filter of the image acquisition device with a single filter needs to be replaced manually, and the work at high altitude It cannot be replaced automatically, and the drone needs to be parked on the ground, which greatly affects the efficiency of aerial photography
