Sampling lattice in HD-UPP. Sensor trajectories (dash-dotted line) lie on a cylindrical surface in \(\mathbb {R}^3\). For easier calculations and graphical representation this surface is mapped onto a plan in \(\mathbb {R}^2\). Points for signal reconstruction (green +) are placed on that surface in a regular grid (a) [14]. Butzer and Hinsen sampling lattice with a skewed coordinate system (b). Coordinate system and sampling lattice for signal reconstruction in HD-UPP (c) [11]. Lines parallel to u represent different sensor trajectories
