A pipe measuring apparatus includes a measurement probe that performs a non-contact measurement of a pipe as a measurable object; and a displacement mechanism that relatively displaces the measurement probe in three mutually orthogonal axis directions relative to the pipe.

Pipe measuring apparatus

In an optical measuring apparatus so structured as to hold a CCD camera and a laser displacement gauge so that they can be three-dimensionally driven at the same time on a stage, a jig including two straight, non-parallel line segments which can be measured by the CCD camera and the laser displacement gauge in the projection plane along the Z-axis direction is mounted on the stage; the straight line segments are measured in the projection plane by the CCD camera and the laser displacement gauge to obtain formulas of these segments; the obtained formulas are subjected to the arithmetic operation to calculate an offset value of the X and Y plane coordinate centers between the CCD camera and the laser displacement gauge; and the offset value is used as position calibration data of the CCD camera and the laser displacement gauge to perform position calibration of the measurement data.

Position calibrating method for optical measuring apparatus

A simple three-dimensional measuring machine 1 having a simple structure which enables the assembly thereof by the end users, and a packing case 100 for facilitating a transport of the machine 1. A pair of columns used when necessity arises and the X axis member 5 are assembled and disassembled and the X slider 6 and the Y slider 7 are also assembled and disassembled through a first means 20 for adjusting the angles therebetween. The Y axis member 8 and the Z slider 9 which has a Z axis member 11 are connected through a second means 30 for adjusting the angles therebetween. The packing case 100 for transfer has a first packing case to house the column 3 and the height adjustment pedestal 2, a second packing case to house the X axis member 5 and the X slider 6, a third packing case to house the Y axis member 8 with the Y slider 7 and the Z slider 9 with the Z axis member 11 connected through the second means 30 for adjusting the angle and a Y-Z axis cover 17, and an exterior packing case.
