PURPOSE:To automatically draw a locus whose moving object is varied with the time elapse by executing repeatedly extracting and identifying jobs of an image data at an interval of a minute time by a computer. CONSTITUTION:By photographing continuously a series of motions of a moving object which follows up a variation of time by photographing machines 1a, 1b, a series of images of objects including the moving object and a still object and a series of time data corresponding to its images are obtained. Subsequently, by selecting the images at an interval of a minute time and inputting them to a computer 6 and comparing them, only an image data of the moving body is extracted. By identifying the image data of this moving body, a locus of the moving object which follows up a time variation is derived. |
