Abstract
While numerous works analyze the theoretical background of compressive sensing (CS) and provide rich mathematical theory, few practical implementations exist and they mostly share the same disadvantage of being either too complex or too expensive to implement. As a result of the reported work, a simple measurement setup for CS using off-the-shelf components is proposed. A simple and portable CS architecture consists of a digital camera, a projector, and mechanical integration elements. Extensive analysis of the proposed measurement system and the detailed calibration method is provided. The presented CS method allows for the use of a low-resolution camera with significant lens distortion for data acquisition. The results of our CS method are nondistorted, high-resolution images, which are obtained from the acquired measurement data using sparse optimization.
