Skippy the photo robot
Tree rings provide us with important information about the climate of the past, which is why the dendro-researchers at WSL measure hundreds of thousands of them every year. Until now, they have had to do this ‘by hand’ with a click of the mouse on a ‘live’ image of an increment core or a stem disc.
Recently, the photo robot known as ‘Skippy’ has made this work easier for them. The increment core or the stem disc is placed on the mobile plate, which is controlled by a computer and moved forward a few millimetres at a time. Each time it stops, a camera mounted on a bracket takes a photo. All the images are then stitched with the help of a computer programme. The resulting high-resolution panorama image is distortion-free and each annual ring can then be measured very precisely.
