At the light of the fundamentals of Compressive Sensing (CS) presented in Chapter 3, it is clear that the phase-shift-based ToF imaging systems described in Chapter 2 offer an appropriate application area of CS. The signals to be sensed are typically not random, but follow a specific structure, which allows them to be sparsely represented in an appropriate dictionary and, therefore, eventually recovered from few measurements. In this chapter we study the most appealing ways of applying CS to PMD-based ToF imaging systems, with the main goal of overcoming the current limits of the technology, introduced in Section 2.4, mostly the poor lateral resolution, derived from the low number of pixels, and the low depth accuracy.
