A real-time FPGA architecture for 3D reconstruction from integral images

Quasi-Interpolation Operators for Bivariate Quintic Spline Spaces and Their Applications

“…The digital-image-processing technique is applied more and more extensively at present, which can be seen in real-time image transmission, digital image restoration, extracting facial features, image synthesis, image compression and encryption, and so on [35,36].…”

FPGA-based hardware CNC interpolator of Bezier, splines, B-splines and NURBS curves for industrial applications

“…In this sense, FPGA have several advantages over other implementations such as reconfigurability, allowing a system on-a-chip (SoC) solution with parallel processing capabilities for real time applications, while maintaining low cost (Osornio-Rios, RomeroTroncoso, Herrera-Ruiz, & Castañeda-Miranda, 2009). Moreover, recent developments on CNC machines show that FPGAs have advantages in hardware applications such as PID (ProportionalIntegral-Derivative) controllers (Astarloa, Lázaro, Bidarte, Jiménez, & Zuloaga, 2009;Osornio-Rios, Romero-Troncoso, Herrera-Ruiz, & Castañeda-Miranda, 2008), parameter identification (MoralesVelazquez, Romero-Troncoso, Osornio-Rios, Herrera-Ruiz, & De Santiago-Pérez, 2010), and image and video processing (Chaikalis, Sgouros, & Maroulis, 2010). On the other hand, it is worth noticing that the majority of the cited works only implement one interpolation technique.…”

Computational Technique of 3D Reconstruction in Integral Imaging using FPGA Hardware

“…In order to overcome these drawbacks of OIIR technique, a CIIR technique based on a pinhole array model has been introduced, in which 3D object can be computationally reconstructed through digital simulation of geometrical optics [8]. Several attempts for 3D object reconstruction and visualization using InIms have been reported in the literature ([10]- [13]). Relying on hardware implementation of digital architecture, several attempts are carried out for 3D scene reconstruction using InIms and accelerating the reconstruction process ( [5], [13]).…”

In this paper, a simple computer-based 3D image reconstruction using a powerful hardware based on FPGA device is proposed.…”
