Enhanced techniques for volumetric stage mapping based on a calibration object are described. An example method includes obtaining a plurality of images of a calibration object, the images being obtained from a plurality of image sensors positioned about the calibration object, and the calibration object having location information associated with a volumetric capture surface on which the calibration object is located; generating, based on the images, a reconstructed object associated with the calibration object, the reconstructed object representing a three-dimensional representation of the calibration object; determining reconstruction quality information associated with the reconstructed object, the determination being based on a ground-truth representation of the calibration object; and outputting the reconstruction quality information.
