Comparison between point cloud and mesh models using images from an unmanned aerial vehicle

•Tree object measurements obtained with point cloud and mesh models are compared.•The effect of the number of images on the object-surveying accuracy was analyzed.•The point cloud is approximately 2% more accurate than mesh models for individual tree measurement.•The number of images does not have a...
