A double-
monocular white light three-dimensional measurement
system used for restoring face defect of patients belongs to fields of optical measurement,
mechanical engineering and medical
engineering. The measurement
system includes a left
monocular measurement head, a right
monocular measurement head, a measurement head support, a measurement head translation mechanism, a control cabinet and a computer. Based on structure optical projection three-dimensional vision measurement technique, the measurement
system employs double-monocular measurement structure,
white light sources which are safe for
human body are employed in a left magic
lantern projector and a right magic
lantern projector for rear projection of physical coding
grating, Gray codes and phase shift coding stripes are projected on left and right faces of patients, after a left camera and a right camera take a view of deformed gating images, measurement of complete three-dimensional face appearance of patients is realized by image decoding, triangle principle and double-eye measurement
data combination. The measurement system can realize accurate data collection of
natural state parenchyma of patient faces under non-
contact condition and provide credible three-dimensional appearance
original data of patient faces for clinic appearance defect restoring therapy.
