摘要： PROBLEM TO BE SOLVED: To provide a system for determining the spatial position and/or direction of one or more object. SOLUTION: This system is formed by an optical sub-system 14 and a non- optical sub-system 12. The optical sub-system includes optical sources 16a, 16b, 16c fitted to an object and a sensor 20 for detecting energy from the light sources, and the sensor generates a signal of the position and/or direction on the basis of an optical sub-system coordinate system fixed to the sensor in response to the detected energy of the light source. The non-optical sub-system generates a signal of the position and/or direction of the object 22 on the basis of the non-optical sub-system coordinate system. A coupling device generates a signal expressing one position and/or direction of the optical or non-optical sub-system on the basis of the other coordinate system. A processor 26 determines the position and/or of one or more objects on the basis of the suitably defined coordinate system in response to a signal generated by the coupling device and the individual sub-system sensors.

摘要： PROBLEM TO BE SOLVED: To provide a method and device for moving body position detection, which eliminates the need for specifying the position of a reflecting body arranged in a movement area and can perform detection without using rotating bodies. SOLUTION: An optical unit 10 composed of a laser oscillator 11 and a CCD camera 12 irradiates a truck 30 as a moving body with laser light in all circumferential directions and photodetects the reflected light of the laser light to obtain photodetection data. Reflecting bodies Hi are arranged at plural positions in the movement area, and the photodetection luminance distribution is different at the respective positions in the movement area because of their reflection. An MPU 21 compares the comparison data obtained from the photodetection luminance distribution and the angle θ from a reference direction obtained by a gyrosensor 40 with reference data stored in a memory 22 to detect the position of the truck 30 according to the comparison result.

摘要： PROBLEM TO BE SOLVED: To accurately specify the origin position of a telescope and at the same time accurately measure delay time in a range-finding station by performing range finding to n targets on the ground whose three-dimensional coordinates are known using a telescope and using n simultaneous observation equations of a range-finding value up to each target on the ground being shown by the specific expression. SOLUTION: A laser beam that is emitted from a laser light source 2a is branched to telescope origin positions OX, OY, and OZ and a light reception means 2c via a half mirror 2b and is applied to either of ground targets T1-T5 (three-dimensional coordinates TX1, TY1, TZ1-TX5, TY5, and TZ5) according to the direction of a telescope of a telescope 1. A laser beam that is reflected by either of the ground targets T1-T5 returns to the origin position of the telescope 1 again and reaches a light reception means 2e in a ranging station 2. Then, a simultaneous observation equation based on an expression is established for each of range-finding values R1-R5 of the ground targets T1-T5 and the three-dimensional coordinates OX, OY, and OZ of the telescope and the maximum likelihood value of the station delay time are obtained by the least square method of each solution.

摘要： PROBLEM TO BE SOLVED: To provide a position measuring apparatus a mobile requiring reflectors being installed at only two positions. SOLUTION: Reflectors 12a, 12b are installed at two or more known positions around a moving passage. A position measuring apparatus a mobile comprises a laser range finder 11 mounted on an automatically guided vehicle 10 and measuring the distance and angle thereof relative to each reflector 12a, 12b by projecting laser light in the horizontal direction toward the reflectors 12a, 12b ands receiving the reflected light therefrom, and a section 20 for operating the position and orientation of the vehicle 10 from the installing position data of each reflector 12a, 12b and the relative distance and angle obtained by the laser range finder 11.
