A PBeL for training non-experts in mobile-based photogrammetry and accurate 3-D recording of small-size/non-complex objects

•Close-range photogrammetry is no longer a word restricted to specialists.•Amateur photogrammetry reliability poses challenges as accuracy is often unknown.•A PBeL is proposed to train non-experts in recording small and non-complex objects.•Amateur mobile-based 3-D recordings reach relative precisions greater than 1:2,000.
