PURPOSE:To display and record loci with high accuracy and in real time by operating the positions of a moving object continuously from the angle information obtainable with a plurality of angle tracers which are capable of automatically tracing the light source which is installed to the moving object and becomes a target thereby obtaining the travel loci. CONSTITUTION:A light source 2 mounted to a moving object 1 generates modulated light from a lamp 3 by its oscillator 4 and modulator 5. The modulated light from the light source 2 is automatically traced by the reflecting mirrors 7 of two units of angle tracers 6, 6' which are installed at the predetermined spacing. The abovementioned tracer 6 condenses the modulated light from the light source 2 in an optical system 8, converts this to an electric signal with a photoelectric transducer 9, sends this through a signal processor 10 and feeds the same back to the reflecting mirror 7 through servo amplifier 11 and servo mechanism 12, thereby letting the reflecting mirror 7 trace the light source 2. The output of the processor 10 is digitized by an A/D converter 13 and at the same time the both of this and the output of an angle detector 14 indicating the angle from the reference line of the reflecting mirror 7 are inputted to a code translator 15. A CPU 17 calculates the position of the moving body 1 from the spacing of two units of the tracers 6, 6' and the angle output of the detector 14 in real time and displayes and records the same. |
