Abstract

Highlights 3D handheld scanner provides great details of the bite marks on the skin. No significant difference in mean surface areas between 3D scanned images and 2D photograph. Excess body hair may significantly hamper the surface details. 3D scanned image of bite mark is useful for forensic evidence preservation.
