Abstract
A three-dimensional (3D) object scanning method includes: controlling, when an invisible light source is off, a first camera device to capture a first image of the target object; and controlling, when the invisible light source is on, a second camera device to capture second images of the target object from a plurality of viewing angles. The target object is painted with invisible markers that are invisible to the first camera device when the invisible light source is off. The invisible markers are visible to the second camera device upon absorbing a light emitted by the invisible light source. The second images are used to determine 3D information of the target object.
