DETERMINING THRESHOLDS TO FILTER NOISE IN GMAPD LADAR DATA

摘要

In one aspect, a computerized method to automatically determine thresholds includes receiving data generated from a Geiger-mode avalanche photodiode (GmAPD) laser detecting and ranging (LADAR) sensor of a scene, determining an overall threshold value for the scene using a binomial distribution and determining post threshold values for each x-y position in the scene. The computerized method also includes, for each x-y position, using a maximum value of the post threshold values and the overall threshold value to filter the data from the scene.
