Demining Project

Danger, Live Mine Field


Landmine detection is a complex and highly dangerous task. Most demining operations are done using hand-held detectors, which means that the operator is always at risk of serious injury or death. One of the most important factors that determines the probabilty of detection is the operator performance. Therefore, it is very important that we train the operator well and are able to assess their performance accurately. The achieve these objectives, we have been developing two training tools, the 3-D tracker for real-time feedback during training, and the virtual mine lane for interactive training. We have been using the 3-D tracker successfully to assess the performance of an operator as a part of a successful training program.

3-D tracking system

The 3-D tracking system consists of two video cameras mounted with a vertical stereo baseline of about 7 feet. The system tracks the detector head at about 30 frames per second, and computes the 3-D world position. It uses this information to build up a coverage map and to compute to speed at which the detector is moving. The coverage map is used to determine if the operator missed any areas during scanning. It is also color coded based on either the speed or the height of the detector. This will show areas where the detector is outside of its optimal operating range.

Virtual mine lane

The virtual mine lane builds on the tracking system by adding elements to simulate a mine lane to allow training anywhere, anytime. A video projector is used to display a ground texture, and optionally the coverage map and mine footprints. A sound is generated to simulate the output that a real mine detector would generate as it passes over a mine.
