摘要： An improved angle measuring device in which rotational irregularity in the form of two cycles or more per rotational cycle of the motor driving device is compensated for completely. A period of time T.sub.1 required for a cutout formed in the periphery of a rotor rotating at a constant speed to make one revolution starting from a stationary reference point, and a period of time T.sub.2 required for the cutout to move between the reference point and an angle measuring point are obtained to evaluate 360.degree..times.(T.sub.2 /T.sub.1) to obtain the angle under measurement. The cutout has an angular width of approximately 90.degree., although angular widths in a range of 5.degree. to 355.degree. can be used as the situation demands.

摘要： An angle measuring device operating without a graduated board and of a type including a disc rotating a constant speed having a reference point fixed on the housing of a disc, an angle measuring arm concentric with the disc and rotatable, and a measuring point provided on the arm. In accordance with the invention, the ratio of an angle measuring time required for the disc to turn from the reference point to the measuring point to a one-revolution time of the disc is multiplied by 360.degree. to obtain an angle which is determined by the reference point, the center of the disc and the measuring point. This is effected with an angle measuring time integrating device for integrating data points corresponding to one-revolution time for each revolution of the disc, and an arithmetic unit for calculating a measured angle according to the ratio of the integrated value of the angle measuring times to the integrated value of the one-revolution times after the disc has made a predetermined number of revolutions.

摘要： A photogrammetric measurement system produces a survey map based on a set of photographed pictures obtained at two different photographing positions. Each of the pictures includes at least one continuous line and at least three conspicuous points away from the continuous line, with at least one of the conspicuous points and remaining conspicuous points being placed at opposing sides of the continuous line. The set of pictures are produced as a first picture and a second picture. First lines are produced between the conspicuous points on the first picture such that the lines intersect the continuous line, thereby generating intersecting points. Second lines are produced between the conspicuous points on the second picture such that the lines intersect the continuous line, thereby generating further intersecting points. A set of corresponding intersecting points are designated on the first and second pictures, and intersecting points are produced on the survey map based on the designated corresponding intersecting points. A line, connecting the intersecting points, is thus produced on the survey map.

摘要： A target, which is photographed with an object at a spot for a photogrammtric analytical measurement, comprises first, second, third standard point members and assistant point members. The standard point members and the assistant point members are covered by a reflecting sheet. A distance between the first and second standard point members equals a distance between the second and third standard point members. Two assistant point members are positioned on a first straight line connecting the first and second standard point members. One assistant point member is positioned on a second straight line connecting the second and third standard point members. The distance between the first and second standard point members, the distance between the second and third standard point members, and an angle defined by the first and second straight lines, are predetermined.
