In order to measure the intersection of rotatable arc guideway system, namely, the distance from the center determined by the rotatable arc guideway to the axis line of rotation, a crosshair target was fixed on the slider sliding along the arc guideway, and a theodolite was installed in the front of the rotatable arc guideway system. Horizontal angles and vertical angles of the theodolite, which directed to the crosshair target sliding on different positions of the guideway while in 0° and 180° positions of the axis system, were acquired. The coordinates of the target on the theodilite coordinate frame were achieved by homogeneous transformation method, the relationships among the readouts of the theodolite, target’s coordinates, some position and attitude errors, the distance between the theodolite and center of the arc guideway were established, by way of linearization and iterated least square method, the arc centers in 0° and 180° angular positions were calculated and then the intersection was attained finally. By simulating the measurement process with two semi-circles, the intersection measurement value is consistent with the practical setting value, it is proved that the proposed method is correct.
