Field Marker Targets

Field Marker Targets (FMTs) can be used with both iWitness & iWitnessPRO photogrammetry software systems. FMTs are designed for law enforcement photogrammetric measurement in tall field grass -- adjacent highway shoulders and median areas involving vehicle crash evidence. FMTs work excellent with iWitness when combined with natural feature marking or with the Weighted Style PM's and/or Cone Style PM's. Other image-based surveying uses of FMTs include the investigation of outdoor burn (char) patterns, accomplished by fire investigators.

FMTs consist of a fiberglass rod 32" (81cm) long, with a detachable white dot-marker placard that is semi-automatically measured to sub-pixel accuracy within iWitness. The photogrammetric white dots are concentric to each side. The placard can optionally be removed for storage, based on the two retaining clips. FMTs are durable and easy to deploy in the field.

FMTs are temporarily staked by simply pushing them into the ground for 3D photogrammetric measurement use.

XYZ Target projection to the ground:
The "Point Offset" tool within iWitness is used to automatically (and accurately) calcuate the ground surface relative to the height of the FMTs white targets.
