Real-time 3D image computation using LUT-based DSP systems

Abstract

In a typical embedded laser-based acquisition system, real-time 3D image computation may be affected by several main factors, like processor speed, complexity of re-mapping functions, the size of the 3D image and the correctness of optical data (artifact correction). To achieve the desired performance, the designer may choose a fully hardware-based solution. However, this will increase the system cost. In this paper, we propose a hardware-software system design framework based on a DSP processor, and look-up tables (LUT) to compute a 3D image in real-time and achieve the desired throughput
