ManagingOcclusions
Anocclusionisanareaontheobject'ssurfacethatisrecordedbyonemeasurementdevice(eitherthelaser
scannerorthecamera),butmissedbytheother.Thisconditionisalsoknownas"parallax",wherethe
camerafailstocaptureanareathatisrecordedbythelaserscannerduetotheoffsetfromthelaserbeam
centertotheRicohThetaZ1lenscenter.Theareaisincludedinthepointcloudbutnotcapturedinthe
PanoCampicture,andasaresultnotcolorizedinthepointcloud.
Occlusionsoccurduetoparallaxissues,similartohowyourleftandrighteyesseeclose-upobjects
differently.Occlusionsoccurmoreoftenforclose-upobjects,andtheyoccurlessfrequentlywithobjects
thatarefurtheraway.
