At present , the competition of oil industry is very fury , so reducing the cost of exploitation of oil is imperative under the situation . but the oil drillers of our country are relatively old , and the control mode drops behind , which result in the long period of making hole and high ratio of aiguille attaint , which is the main restrict factor of reducing the cost of oil exploitation 随着石油行业竞争的日趋激烈，降低石油的开采成本就势在必行，于是研制新型的石油钻机就显得尤为重要，因为国内目前使用的钻机比较陈旧，控制方式非常落后，导致钻井周期长、钻头损坏率高，这是降低石油开采成本的重要制约因素；而且落后的控制方式使得钻井过程容易发生溜钻、卡钻等事故。

It is the first time that the theory of wavelet has been applied in the signal processing of the codog power plant experiment rig and wavelet transform denoising was used , it may keep the aiguille and saltation parts , wipe off the noise and pick up the useful signal , it is benefit to analysis the result in experiment 把小波分析理论应用于codog实验台信号处理中，用小波变换进行信号消噪，可以很好的保存有用信号中的尖峰和突变部分，将信号的噪声部分去除，从中提取出于有用信息，更有利于实验结果分析。

Secondly , programmed the image processing arithmetic code which include the bottom arithmetic for the general condition comprises threshold division , region combination and informate and the middle level arithmetic for the given task comprises detecting the line dation creirection according to the hough transform in order to fix on the hole ’ s azimuth angle , detecting the aiguille tip position according to the image movement according to the environment and the image format 然后,根据目标环境要求和摄像机采集图像格式,开发了图像处理算法程序。图像处理算法包括底层算法和中层算法两部分,底层算法针对通用情况,包括阈值分割、区域合并和信息生成。中层算法针对具体任务设计,包括利用hough变换检测棱线的方向,从而确定圆孔的方位角和利用基于图像运动检测钻头尖端位置。
