Canon 550D digital SLR camera

The Canon 550D Digital SLR has excellent image quality and a lightweight body. The focus of the lens is fixed to infinity, the ISO is set to 200, and the aperture is fixed to f 3.5 resulting in a minimum shutter speed of 1/2000th of a second. These settings reduce motion blur. The camera is triggered once per second (1 Hz).The Canon 550D Digital SLR has excellent image quality and a lightweight body. The focus of the lens is fixed to

Each flight results in well over one hundred images that are combined in a mosaic with ~1 cm pixel resolution from ~50m.Each flight results in well over one hundred images that are combined in a mosaic with ~1 cm pixel resolution from ~50m.

StumpThe detail in the images is impressive and these images are idea for generating 3D point clouds using Structure from Motion techniques.

Multispectral sensor

Tetracam Mini MCA

MiniMCAThe Mini MCA can be fitted with a range of filters; we have chosen 12 10nm filters for our initial investigations.

FCPoppiesThe high detail multispectral imagery can provide insights into plant health, water stress and irrigation efficiency. The image above portrays a poppy crop under irrigation; non-irrigated poppies are clearly apparent in the left of the image.

Thermal sensor

FLIR Photon 320 thermal sensor

FLIRThe FLIR camera and datalogger weigh under one kilogram.

FLIRImageThe imagery results in approximately 10cm pixels from ~50m.

LiDAR

Ibeo Lux LiDAR sensor

IBEOLUXThe Lidar system we use is found the front grill of high-end luxury cars, it was not designed for UAV use.

LuxImageThe point clouds produced are far denser than traditional airborne systems (approximately 10 times the number of points per metre, i.e. 60 vs 6 points per metre)
