Document Type and Number:
Japanese Patent JP2788039
Kind Code:
B2
Abstract:
PURPOSE:To obtain stable tracing by inputting a drive speed of a drive base and a scanning speed of an image pickup device with a controller and applying time correction to picture information of a video signal obtained from the image pickup device at a relevant drive speed into picture information at the start point of time of the image pickup frame. CONSTITUTION:A geometrical gravity center correction device 11 is provided to an output of a picture processing unit 4, geometrical gravity centers x', y' subjected to time correction at a relative speed calculation value between an image pickup device drive table 2 and a mobile object based on drive base speed signals VH, VL inputted from a drive base controller 6 are calculated and outputted to a position arithmetic unit 5 from the geometrical gravity centers x, y. The corrected geometrical gravity centers x', y' are inputted to the position arithmetic unit 5 and an azimuth signal representing the present image pickup azimuth of a far infrared ray camera 1 is inputted from the drive base controller 6. Thus, the position arithmetic unit 5 outputs a position signal to the drive base controller 6 so that the pickup direction center of the far infrared. ray camera 1 traces the mobile object 1 from both signals.
