Abstract:
1. A three-dimensional measurement system comprising: a projection apparatus configured to project a pattern image on a measurement target object; an image capturing apparatus configured to capture an image including the target object on which the pattern image is projected by the projection apparatus; a control apparatus configured to obtain distance information from a captured image captured by the image capturing apparatus; and a synchronization control apparatus connected to the control apparatus via a first output interface (I/F) and a first input I/F, connected to the projection apparatus via a second output I/F, and connected to the image capturing apparatus via a second input I/F, and configured to perform synchronization control of the projection apparatus and the image capturing apparatus based on an instruction from the control apparatus, wherein the synchronization control apparatus comprises: an error detection unit configured to detect an error; an embedding unit configured to embed error information detected by the error detection unit in a captured image input from the second I/F; and an output unit configured to output to the control apparatus via the first input I/F the captured image in which the error information has been embedded, and wherein the control apparatus comprises an extraction unit configured to extract the error information from the captured image in which the error information has been embedded.
