Abstract

See full text

Using a hand-held range finding device to range an object in a field of view is difficult due to user-induced jitter. In particular, user-induced jitter introduces uncertainty as to which object in a field of view is actually ranged. Current approaches attempt to mitigate user-induced jitter by requiring a user to mount the hand-held range finding device onto a stabilizing device (e.g., a tripod). However, such approaches require the user to carry additional equipment. Embodiments of the present disclosure enable the user to visually confirm which object in a field of view is actually ranged during a range finding event by generating a composite image that includes a visual representation of a laser pulse emitted by the range finding device reflecting off an object in the field of view. Advantageously, disclosed embodiments provide true hand-held range finding capabilities without requiring the use of stabilization assistance techniques.
