| Summary: | Crime scene is one of the most secured place which cannot be access easily and all the
evidence and other things in the scene should not be touch or move which could
happened in room or open area. The main objective of this paper is the use of the
target marker as the control point will determine the exact x,y and z position of the
evidences and victims in addition produce 3-dimensional modelling. Approximately
two or more control points using target marker which the positions are justify by using
handheld application which is "Easy GPS" will be located at the comer of the room by
using close range photogrammetry. By using Photomodeler Scanner and Agisoft
Photoscan software, the positions of the evidences and victims can be transferred from
control points. At the same time, the 3-dimensional modelling can be developed and
the evidences and victims can be measured. The accuracy of the measurement
compared with conventional measurement by using ruler. In conclusion, this study
provides a vital step in forensic mapping applications for police investigators. It
provides the practical solution to mapping crime scene by using close-range
photogrammetry methodology. |
