基于存在概率图的圆检测方法.提出了一种基于存在概率图的圆检测方法, 将图像边缘点共圆结构信息变换为圆存在概率图中的峰, 再通过峰值检测确定圆的参数。该方法能有效地检出边缘不清晰、不完整的圆形轮廓, 具有占用内存少, 阈值物理意义明确的特 点, 较好地解决了标准 HT 圆检测方法中占用内存空间大, 计算效率低的问题。实验结果表明圆存在概率图具有较强的稳定性和分辨能力.-Probability map based on the existence of circle detection method. Presents a probability map based on the existence of circle detection method to image edge points, a total of circular structure of the existence of information is transformed into a round map of the peak probability, and then through the peak detector to determine the parameters of a round. This method is effective in detecting the edge of unclear, incomplete circular profile, with less memory, the physical meaning of the threshold specific characteristics, a better solution to the standard circle detection method HT memory space, the computational efficiency of low- problems. The experimental results show that the existence of the probability circle map has strong stability and resolving power.

Visual Basic 6中发送邮件的新方法 用VB6编写发送邮件的程序，有多种E-mail组件可供选择，如MAPIMessages、IIS4.0附带的CDONTS（NTS Collaboration Data Objects）以及许多第三方厂商开发的Email软件等。本文介绍用CDONTS开发VB下的邮件程序方法。 -Visual Basic 6 to send e-mail new method to prepare to send mail using VB6 procedures, E-mail has a wide range of components to choose from, such as MAPIMessages, IIS4.0 incidental CDONTS (NTS Collaboration Data Objects), as well as many third-party manufacturers to develop the Email software. This article describes the development of using CDONTS mail program under VB method.

倒车雷达只需要在汽车倒车时工作，为驾驶员提供汽车后方的信息。由于倒车时汽车的行驶速度较慢，和声速相比可以认为汽车是静止的，因此在系统中 可以忽略多普勒效应的影响。在许多测距方法中，脉冲测距法只需要测量超声波在测量点与目标间的往返时间，实现简单，因此本系统采用了这种方法。-Reversing radar only need to work in the car when reversing, the rear car for the driver to provide information. As the reversing of vehicles traveling at slower speeds, and speed of sound can be compared to consider car is stationary, and therefore in the system can ignore the impact of the Doppler effect. Ranging in many methods, ranging pulse ultrasonic method only measured in the measurement points and the round-trip time between the target and achieve a simple, this system uses this approach.
