Traditionally, prism-based cameras are often selected over trilinear cameras when it comes to bulk material scanning, as the inherent line-shift of a trilinear camera can only be corrected when the object scan velocity is known. In this article it is demonstrated that the traditional approach is not always necessary if the right trilinear sensor is selected and operated in binning mode to average multiple pixels.
