Designed and sold by DeChant Consulting Services (DCS) Inc., Weighted and Cone Style Photogrammetric Markers (PM's) assist in measuring features points of interest during accident investigation. Noteworthy in their functionality, the PM's assist in fast and accurate camera orientation in iWitness to quickly image and measure a scene. PM's are used by law enforcement investigators and accident reconstruction practitioners across America. The combination of PM's affords very rapid and safe evidence mapping at the scene.
Below are sample illustrations of the DCS Weighted and Cone Style Markers. The white dots and alpha characters are double-sided and concentric.
On the left: The face and base of an alpha character PM with galvanized weight, which is affixed by special hook & loop Velcro. Center: The sand bag weighted single dot DM. On the Right: A crash scene were police investigators mapped the incident with a consumer grade digital camera, the PM's and iWitness. The PM's work well in conjunction with the iWitness target offset feature which enables the 3D point to be automatically projected in the Z-axis up/down direction (e.g., to the ground surface were they are placed.) The XYZ projected coordinate(s) can then be optionally exported to CAD in the industry standard DXF format. The Weighted Style PM's work excellent in combination with the Cone Style Markers.
