Data From: A Trunk Diameter Estimation Mobile App for the Masses

Overview This dataset contains RGB and depth images (raw images and text files) of tree trunks collected using Google ARCore. It has 154 samples from four countries, with DBH ranging from 4.8-155.3cm. We annotated aspects like trunk shapes, leaning, lighting conditions when captured, etc. The data was originally intended for evaluating our designed tree diameter measurement app (https://github.com/MingyueX/GreenLens). Data introduction treedata.zip contains three folders - rgb, depthimg and depthtxt - representing raw RGB images, depth images and depth text files respectively. data_label.xlsx includes the labels and corresponding descriptions. Usage Notes The rgb and depthimg folders contain jpg images with 480*360 resolution, where the depthimg images are obtained by reading the raw text files in depthtxt folder and resizing to 480*360. The files with no extension in the depthtxt folder are stored in the format as x-coordinate of pixel, y-coordinate of pixel, depth measurement of pixel and confidence value.
