车辆牌照识别VL PR (V eh icle L icense P late Recognit ion) 是智能交通系统ITS ( Intelligent T ranspo rtat ion System ) 的重要部分, 有着巨大的社会和经济效益L 车辆牌照图像二值化方法的研究是 VL PR 中的关键技术, 通常都采用经典的Bernsen 算法和O tsu 算法L 但由于光照不均、摄像机畸变、曝 光不足、动态范围太窄和车辆牌照被污染等原因, 车辆牌照图像的质量往往不佳, 常存在严重伪影和字

GPS测量直接提供的坐标（B,L,H）是1984年世界大地坐标系(Word Geodetic System 1984即WGS-84)的坐标，其中B为纬度，L为经度，H为大地高。而在实际应用中，我国采用的是1954北京坐标系或者1980西安坐标系下的高斯投影坐标（x ,y）。如何实现WGS-84坐标系与北京54坐标系或者1980西安坐标系的转换，一直是GPS应用中关心的热点。
It is important to predict the intensity distribution in focusing plane for designing the X-ray compound refractive lenses. On the basis of analyzing the structure of X-ray compound lenses and comparing it with Fraunhofer diffraction system, it is co
We propose a two-cascaded, constant-resistance, symmetrical bridged-T amplitude equalizer for a high-speed visible light communication (VLC) system. With the pre-equalization circuit, the -3 dB bandwidth of the VLC system can be extended from 12 to 2
A compact fiber Bragg grating (FBG) diaphragm accelerometer based on L-shaped rigid cantilever beam is proposed and experimentally demonstrated. The sensing system is based on the integration of a flat diaphragm and an L-shaped rigid cantilever beam.
This paper describes a new design for the test light source of an L/U-band extended optical fiber line testing system and the side-band suppresser ratio of the test light should be more than 70 dB.
