Targets measured during the experiment.

Target name	Latin name	Bounding box dimensions (m)			Point number average and standard deviation
		x	y	z
Norway maple (large)	Acer platanoides	7.05	6.92	9.10	3,191,100 ± 30,500
Norway maple (small)	Acer platanoides	2.19	2.32	6.19	231,200 ± 2,500
Lamppost	Columna lucerna	0.95	0.76	4.40	45,300 ± 300

The target bounding boxes are calculated from the points of the initial scans measured at 20:10 h. Point number averages and their standard deviations are calculated from all DAIs used in the analysis. Object point clouds were delineated manually from the combined point cloud of all three scanning locations. A buffer zone was left around each object volume to accommodate any systematic movements in the object point cloud during the experiment. Reported bounding box dimensions, point number averages and standard deviations were calculated after all pre-processing steps.
