What is DRI:
Detection, Recognition, Identification Ranges?
The question the most frequently asked to thermal imager manufacturers is certainly: how far can the IR camera detect a target? It is indeed a good criterion to qualify one sensor from another considering the final application. And the answer given to this question will probably include the “DRI ranges” expression.
DRI stands for Detection, Recognition and Identification. DRI ranges, expressed in km (or miles), can be found in the specification table of infrared camera brochures. In order to select the right sensor meeting the application requirements, these DRI ranges have to be, first, perfectly defined, but also assessed with regards to globally adopted industrial standards.
What does "DRI" mean?
John Johnson, a scientist from the Army Night Vision Laboratory, was a pioneer in 1958, conducting experiments to test observers’ ability to identify targets through analog sensors. The terms “Detection”, “Recognition” and “Identification” were defined as follow:
· Detection: ability to distinguish an object from the background
Recognition: ability to classify the object class (animal, human, vehicle, boat …)
Identification: ability to describe the object in details (a man with a hat, a deer, a Jeep …)
The following pictures illustrate these definitions:
Detection: At several kms, two targets are Recognition: A human is walking along Identification: Two males with trousers
detected out of the background the fence and jackets are identified, one is smoking.
Our factory has many types thermal imager, such as thermal camera for cars, handheld thermal monoculars, thermal binoculars, multifunction thermal binoculars,thermal weapon sight, clip on thermal weapon sight. There are some videos about thermal imagers, pls kindly check it for your reference
