The Field of View (FOV) Calculator is used to help identify several field of view metrics associated with Leonardo DRS major products including: Tamarisk® 320, Tamarisk®640, UC 640 17-micron, and Zafiro® 640
Use this tool to determine the number of "pixels on target" given a particular product, lens selection, and range. The FOV Calculator presents the number of pixels on screen for a given subject, whether a dog, person, truck, or airplane, as well as maximum ranges for subject detection, recognition, and identification.
A zip file will be downloaded that contains the calculator spreadsheet and associated imagery. Extract the embedded files into a single directory. Open the "Field_of_View_Calculator_rev*.xlsm" file to begin using the FOV Calculator.
IMPORTANT: Enable macros within Microsoft Excel for the FOV Calculator to operate.
Once the object size has been entered, the "Range to Object" section to the right of the final inputs will display the "pixels on target" information and the maximum ranges for object detection, recognition, and identification for this particular set of inputs.
