Firstly, radial horizontal component and transverse horizontal component are derived from tri-channel seismic data at the surface and the bedrock in borehole array by back-azimuth decomposition method, and the histories of radial and vertical components are divided into two parts by Sg wave arrived time. Moreover, it is supposed that transverse horizontal components are made up of SH wave, while vertical component and radial horizontal component are constituted by P-SV wave system.

针对钻井台阵的两处三分量加速度记录，根据反向方位角将两水平分量分解为径向水平分量和横向水平分量，假设横向水平分量由SH波系组成，竖向分量和径向分水平量由P-SV波系组成。

A fast extraction method of beer bottle rasied character is introduced in this paper. It is the technique combination of moving target tracking based on dynamic image sequence with edge detection algorithm for speeding up the processing of character extraction to meet the demand of on-line detection in industry. First dynamic image sequence is obtained with an area CCD camera, and the background frames are detected based on the coherence between the background and character image from the video and inevitability of background frames emergence.

运用基于动态图像序列的运动目标跟踪技术，结合图像边缘提取理论中的检测算子模板，提出了一种快速提取啤酒瓶凸性字符的方法：首先采用单个面阵CCD得到啤酒瓶字符的运动图像序列，然后利用背景在运动图像序列中的镜头突变性和出现的必然性，检测视频流中的背景帧，最后采用基于边缘检测的背景配准方法，得到运动图像和校正背景图像的差分图像，恢复出真正的运动物体。
