INFRARED GUIDE DEVICE AND INFRARED GUIDE METHOD

摘要

PROBLEM TO BE SOLVED: To control the specific position of a tracking point according to the distance from a target flying body.;SOLUTION: Infrared image data of mid-wavelength band received by a mid-wavelength infrared ray detection part 11a is fetched, a target image in mid-wavelength infrared ray is determined and segmented in a mid-wavelength image processing part 12a, and the position of target is calculated. Infrared image data of long-wavelength band received by a long-wavelength infrared ray detection part 11b is fetched, and a target image in long-wavelength infrared ray is determined and segmented in a long-wavelength image processing part 12b. The position of target corresponding to a position selected from the mid-wavelength image data is calculated, and the magnitude of target (the number of segments) is also determined. In a target determination processing part 13, whether the magnitude of target is larger than a threshold or not is determined, the target position in the mid-wavelength image is reported as the tracking point to a guide processing part of the latter stage until it reaches the threshold. When it reaches the threshold, the mid-wavelength image is switched to the long-wavelength image, and the target position in the long-wavelength image is reported as the tracking point to the guide processing part of the latter stage.;COPYRIGHT: (C)2007,JPO&INPIT
