The invention discloses a hand-held spatial object surface coordinate measuring instrument and measuring method. The hand-held spatial object surface coordinate measuring instrument is composed of a cylinder, a cone and a sphere; a coordinate measuring unit is fixed to the axis of the cylinder, data fusion and coordinate computing are conducted according to data output by a sensor on the coordinate measuring unit, and coordinates of an object at the end of the coordinate measuring instrument are obtained. The method comprises the steps that firstly, coordinates of an initial point and the distance between the coordinate measuring unit and the tail end of the sphere are determined; the direction of the coordinate measuring instrument at the initial point and spatial position coordinates ofthe coordinate measuring unit are calculated; displacement change of the measuring unit when the coordinate measuring instrument moves from the initial point to a measuring point is calculated; the coordinates of the coordinate measuring unit at the measuring point are calculated; the direction of the coordinate measuring instrument at the measuring point is calculated; coordinates of the measuring point are calculated.
Description
technical field [0001] The invention relates to the field of coordinate measurement, in particular to a hand-held space object surface coordinate measuring instrument and a measuring method. Background technique [0002] Accurate measurement of coordinates of object surface points is the basis for further production and processing. At present, the commonly used equipment for measuring the coordinates of points in space mainly includes infrared camera array measuring devices, laser trackers, articulated arm measuring machines and orthogonal coordinate system three-coordinate measuring machines. [0003] Among them, the infrared camera array and the laser tracker need to fix mark points on the surface of the object to be measured before coordinate measurement. The infrared camera array needs to paste mark points on the surface of the measured object, and the laser tracker needs to fix the reflector on the surface of the measured object. And it is required that there should no...
