Three-dimensional measuring apparatus and control method therefor

摘要

According to the invention, reliability is calculated in consideration of an uncertain error due to noise in three-dimensional measurement, thereby obtaining correct reliability as compared with a conventional technique. To achieve this, a three-dimensional measuring apparatus includes a projector which projects a striped light pattern onto an object, a camera which captures a reflected light pattern from the object onto which the striped light pattern is projected, and a calculation processing unit which executes various arithmetic operations. The calculation processing unit includes a noise calculating unit and a reliability calculating unit.

主权项

1. A three-dimensional measuring apparatus for measuring a three-dimensional shape of an object to be measured, comprising:
at least one processor; and a memory storing a program to be executed by the at least one processor, wherein the at least one processor functions as:
an image obtaining unit configured to obtain an image including an object to be measured onto which a pattern is projected by a projecting unit, wherein the image is captured by a capturing unit;a noise information obtaining unit configured to obtain noise information in measurement of the three-dimensional shape of the object to be measured, that is caused by at least one of the projecting unit, the capturing unit, and the object to be measured;a reliability obtaining unit configured to obtain, based on the noise information, reliability of measurement of the three-dimensional shape of the object to be measured; andan acquiring unit configured to acquire, based on an image captured by the capturing unit and the reliability, the three-dimensional shape of the object to be measured.
