Projectile-Deviation measurement is a key part of shooting calibration of anti-aircraft artillery systems. In recent years, as the imaging and computer processing speed improved significantly, it makes real-time analysis and getting the deviation from projectile-shooting scene possible. This paper makes a deep research on projectile-deviation measurement using image processing technology, combined...
Reprogramming is essential to wireless sensor networks. Current research in reprogramming is almost based on update function of all nodes in a network, the nodes in target area do special task is seldom discussed. In this paper we proposed a reprogramming scheme to transmit code image to target nodes, and implement an effective route algorithm in reprogramming scheme. Then we compared our approach...
A FPGA-based video capture, output and pre-treatment system has been developed. The system adopts the I2C bus protocol and link-port data transfer protocol. And also it combines PAL video format to complete the process of video-capture, decode, encording and output. With the help of IP core provided by Altera company, it achieves the DDR controller, providing storage space for video images. Median...
A miniature high-speed real-time video tracking platform which is based on the core of FPGA+DSP has been developed. The platform adopts I2C bus, link-port data transfer protocol and multi-DSP high-speed video processing. Through the combined use of DSP and FPGA, the platform has the following characteristics: high integration, strong computing power, flexible structure, good expansibility and so on,...
Combining expressway reconstruction project number 20 and number 21 engineering entity of An Xin in HeNan province. At the target mix design of asphalt mixture in Mid-Surface of AC-20, found in the process of testing specimen density of using a basket with netting on top of coarse aggregate and Marshall, the aggregate and Marshall can produce certain effect on its apparent density and bulk density...
Now, USB interface has became the most extensive interface in computer and computers' peripheral equipment. This paper introduces a design of data acquisition equipment based on USB. First it introduces the USB protocol, the structure and the function of the EZ-USB FX2 chip CY7C68013A and then this paper expatiates on the implementation of this data acquisition equipment in the aspects of both hardware...
This paper puts forward a fault diagnosis expert system based on rough set theory on foundation of traditional radar equipment fault diagnosis: in order to solve the bottle neck problem in the expert system, which is difficult in acquiring completing knowledge. The systems starts from the decision table of historical fault data and reduces by rough set theory, and then construct the model for expert...
