In order to solve the problem that Camera Link standard interface used by the current industrial camera and image acquisition card could be realized only by making use of special integrated circuit, field programmable gate array (FPGA ) of Virtex5 series—the latest product of Xilinx was used, and at the same time very high speed integrated circuits hardware description language (VHDL) programming...
Dense stereo disparity map provides a robust method on distance measurements in a 3D scene. Due to its computational complexity in nature, it has been a challenge to achieve real-time processing. In the past years, various algorithms have been studied in order to reach the goal of real-time processing. In this paper, a Dynamic Time Warp (DTW) algorithm is proposed. The DTW algorithm provides excellent...
This paper describes the initial steps in the development of an object detection system for manipulation purposes, to be embedded in a mobile robot. The goal is to design a robotic system to aid workers in a manufacturing plant. The proposed implementation involves the integration of a Field Programmable Gate Array (FPGA) based electronic module with the manipulator arm of the robotic platform. The...
This article focuses on realizing an object tracking and image capture system on a FPGA. The system processes each picture with size of 640×480 pixels which is coming from input image data captured by an external CCD camera. Firstly, the RGB format of input image data is transformed to HSV format through color space transformation. Secondly, the value (also called intensity) of HSV format image is...
In this paper a hardware approach for evaluating motion detection of vehicles on transit roads was proposed. A motion detection method is used through computational vision with a fixed camera which is based on the difference between the current image and a reference image of the environment that is being monitored. Results are compared with a software approach in order to validate and show the effectiveness...
This paper presents a high-speed video transfer scheme and a real-time infrared spots detection algorithm designed for field programmable gate array (FPGA) implementation. Rather than IEEE 1394a, two IEEE 1394b interfaces are alternatively used to ensure high-resolution image transfer in real time. In order to execute fast infrared spots detection, a parallel algorithm that processes four pixels per...
This paper proposes a digital scene simulator system for point target detecting and tracking. The hardware platform mainly consists of FPGA and DSP, which are grouped together in an efficient way. And a target detecting and tracking algorithm is proposed and implemented in the platform. Experimental results show that proposed system can simulate deep out space scene and test an algorithm that is efficient...
The new generation of field programmable gate array (FPGA) technologies enables an embedded processor intellectual property (IP) and an application IP to be integrated into a system-on-a-programmable-chip (SOPC) developing environment. Therefore, in this paper, we present an efficient HW/SW codesign architecture for JPEG encoder and its FPGA implementation. It consists of a NIOS II processor that...
A new generation of optical devices that generate images covering 360 degree field of view, namely catadioptric cameras, is slowly emerging. Because of the concentric annular distortion, the omnidirectional images need to be transformed into panoramic images. In omnidirectional visual surveillance systems, it is a challenge to realize panoramic unrolling in real time, especially for high-resolution...
The multi-angle spectro-polarimetric imager (MSPI) is an advanced camera system currently under development at JPL for possible future consideration on a satellite based aerosol-cloud-environment (ACE) interaction study as outlined in the national academies 2007 decadal survey. In an attempt to achieve necessary accuracy of the degree of linear polarization of better than 0.5%, the light in the optical...
Trends of high power usage in portable consumer electronics and high speed designs is an important factor that biases the selection of an ASIC over a FPGA. ASICs are optimized to minimize the amount of logics used for a particular application; reductions in power are noticed when compared against FPGAs design for the same application. On the other hand, some FPGAs equipped with run-time reconfiguration,...
