置を備えたことを特徴とする画像処理追尾装置。 In an image processing tracking device that locates and tracks a target by detecting the target's radiated infrared rays, an optical sensor 1 receives radiated infrared rays from the target.
an optical sensor 2 that receives the radiated infrared rays of the portion to be observed by the optical sensor 1 in the next frame; a detector 1 that detects the signal received by the optical sensor 1 and outputs a received signal proportional to the intensity of the infrared rays; a detector 2 that detects the signal received by the optical sensor 2 and outputs a received signal proportional to the intensity of the infrared rays; a target image extractor that creates a target image signal from the received signal output from the detector 1; The detector 2
a background image extraction section that creates a background image signal from the received signal output from the target image signal; a delay circuit that delays and outputs the background image signal until the next target image signal is output; and a delay circuit that outputs the background image signal from the target image signal and the delay circuit. a background image suppression unit that removes the background image component included in the target image signal by comparing the output background image signals, selects only the image signal obtained from the target, and outputs a target image compensation signal; a signal processing unit that outputs an angular error signal from the compensation signal; and a part that causes the optical sensor 1 to move the optical sensor 1 in the target direction based on the angular error signal and observe the optical sensor 2 in the next frame based on the amount of change in the angular error signal. An image processing tracking device characterized by being equipped with an optical servo device that drives.
