Imaging systems including real-time target-acquisition and triangulation features and human-machine interfaces therefor

Imaging systems that automatically calculate, in real time, relative locations of acquired targets relative to datum targets. In some embodiments, an imaging system of this disclosure can be instantiated as a handheld imaging device having a live-view imaging system or a thermal imaging system, or both. Some embodiments include a ranging system that fires upon the release of a hard button to minimize movement of the imaging system during target acquisition. Some embodiments include speed estimating and/or time of arrival estimating features. Some embodiments can communicate with an external device, such as a central controller device. A central controller device of this disclosure may include triangulation, speed estimating, and/or time of arrival estimating features. Some embodiments of a central control device may allow users to set up and make mission assignments. Some embodiments allow sharing of data among devices, in some cases only on a mission-by-mission basis.
