Sweep Monitoring
Description



Stereo cameras record how the trainee operates a land mine detector

The SMS consists of a pair of stereo cameras that track a target on the head of a demining sensor. The target is a brightly-colored ball that’s mounted on top of the mine detector. As the trainee sweeps the detector across a simulated minefield, the SMS records the position of the target thirty times per second.

From this positional data, the SMS measures a trainee’s performance in areas critical to successful mine detection: sensor head traverse speed, sensor height above ground, coverage area, and gaps in the swept area. This information is shown on a computer display that’s monitored by the training supervisor, giving immediate feedback through color, coverage, and speed vs. height plots.

The SMS also gives real time audio feedback to the trainee, beeping when mines are detected and giving verbal messages (such as "too fast” or "too slow”) about overall performance. This feedback helps to improve the trainee’s skill at detecting mines.

At the end of each session, the SMS summarizes the trainee’s performance in terms of coverage rate, covered area and mine target location. Data recorded during training sessions can be saved and reviewed later.
