TARGET SEARCHING DEVICE, TARGET SEARCHING METHOD AND TARGET SEARCHING PROGRAM

摘要

PROBLEM TO BE SOLVED: To easily identify a detection target when searching the detection target by use of photographing means.SOLUTION: An aircraft 1 searching a prescribed detection target by use of an optical camera 14 comprises: a display 15 which displays an image photographed by the optical camera 14; and a controller 18. The controller 18 extracts a region of interest WA including an identification object T estimated as of the detection target from a display image on the display 15, calculates representative values Pin, Pout of the image feature amount at both the inner and outer sides of the region of interest WA in the display image and representative values Pi of the image feature amount in a plurality of small regions SA made by dividing the region of interest WA, and extracts the small region as an object existence region TA where the identification object T exists when the representative value Pi of the image feature amount in the plurality of small regions is close to the representative value Pin of the image feature amount at the inner side of the region of interest WA in comparison with the representative value Pout of the image feature amount at the outer side of the region of interest WA.SELECTED DRAWING: Figure 2
