Data processing apparatus, data processing method, and storage medium

A data processing method which processes measured data obtained from a first line sensor and a second line sensor which measure a shape of a measured target as measured data on two-dimensional coordinates, the method comprising:

• obtaining measured data from the first line sensor and the second line sensor, wherein a first coordinate plane measured by the first line sensor and a second coordinate plane measured by the second line sensor are the same or are parallel, and a reference plane plate positioned so that a surface is orthogonal to the first coordinate plane and the second coordinate plane is measured in two or more positions differed by rotation around an axis orthogonal to the first coordinate plane and the second coordinate plane, and
• calculating an angle between the same coordinate axes in the first coordinate plane and the second coordinate plane and a relative position of an origin of the first coordinate plane and an origin of the second coordinate plane based on measured data obtained from the first line sensor and the second line sensor in the two or more positions of the reference plane plate.

A non-transitory computer-readable storage medium storing a program causing a computer which processes measured data obtained from a first line sensor and a second line sensor which measure a shape of a measured target as measured data on two-dimensional coordinates, the program causing a computer to:

• obtain measured data from the first line sensor and the second line sensor, wherein a first coordinate plane measured by the first line sensor and a second coordinate plane measured by the second line sensor are the same or are parallel, and a reference plane plate positioned so that a surface is orthogonal to the first coordinate plane and the second coordinate plane is measured in two or more positions differed by rotation around an axis orthogonal to the first coordinate plane and the second coordinate plane, and
• calculate an angle between the same coordinate axes in the first coordinate plane and the second coordinate plane and a relative position of an origin of the first coordinate plane and an origin of the second coordinate plane based on measured data obtained from the first line sensor and the second line sensor in the two or more positions of the reference plane plate.
