Abstract: Apparatus and associated methods relate to a volumetric measurement system using three dimensional (3D) ToF cameras. In an illustrative example, a VMS may include at least one 3D distance sensor unit for monitoring a volume of objects in a region of interest (ROI). The VMS may, for example, include a set of user-defined parameters including the ROI, and temporal distribution of measurement attributes associated with the ROI. In some implementations, the VMS may be activated to automatically generate a set of error compensated volumetrics. For example, the VMS may apply a 3D profile, generated based on signals received from the 3D distance sensor, to an error compensation model. Based on measurement attributes generated from applying the error compensation model, the VMS may, for example, generate a set of error compensated volumetrics. Various embodiments may advantageously compensate for errors including occlusion of objects from the 3D distance sensor.
