Detection Distances

The graph belows shows detection distances for human-sized objects and car-sized objects.  A human is approximated as an object which is 1.8 m x 0.5 m.  An "Object" below is defined as 2.3 m x 2.3 m.

According to the Johnson Criteria, the minimum resolution (pixels on target) required to achieve a 50% probability that an observer can discriminate an object at a certain range to the specified level are:

• Detection — an object is present: 2 +1/-0.5 pixels
• Recognition — the type object can be discerned, a person vs. a car: 8 +1.6/-0.4 pixels
• Identification — a specific object can be discerned, a woman vs. a man, the specific car: 12.8 +3.2/-2.8 pixels
