ABSTRACT
This chapter discusses the laser scanning creates a “point cloud” comprising millions of three-dimensional data points of a scanned scene, which can be converted to a 3D model to be used as an effective communications tool for juries. The handheld laser scanner is prevalent within the forensic sector—so far—but they can provide value to investigators with particular, challenging crime scene aspects such as bodies, small spaces, behind or under furniture or vehicle interiors. The reduced time spent recording a scene with laser scanning means it is possible to process more crime scenes, and with fewer people. The laser scanner is particularly valued for its ability to digitally preserve the stored crime scene point cloud once the scene has been scanned. One of the report’s key components is comparisons of the capabilities of commercially available 3D laser scanning instruments, their use, benefits, and limitations.
