【摘要】 在地震测井施工中,为监测地下检波器的运动特征,需应用三维监测技术。首先从映射几何的角度深入分析OpenGL的三维监测技术,建立OpenGL虚拟场景,然后分析检波器模型内外方位元素的表达,利用三维绘图技术建立检波器的立体模型,最后对所获取的坐标数据进行快速的三维绘图技术处理,形成实时可靠的立体模拟界面。实验结果表明:检波器的方位角模拟精确度能保证在1°以内,满足后期简化数据处理的要求。该技术应用在地震测井中时,具有远程、可靠、无损检测等特点,为操作人员提供直观可靠的观测决策平台,并且结合实际需求能够扩展多种功能模块,可广泛应用于测井过程中方位数据的获取。更多还原

【Abstract】 In seismic uphole survey construction, 3D monitoring techniques need to be used in such fields to monitor the motion characteristics of the detector. This paper firstly focuses on bridging the 3D monitoring technology of OpenGL from geometric mapping and establish OpenGL virtual scene. Then it analyses the expression outside elements of the detector model and builds a3 D model of the detector by 3D graphics technology. Finally,it uses the rapid processing of 3D graphics technology to form a real-time and reliable 3D simulated interface. Outdoor experimental results show that the analog accuracy of detector azimuth can be guaranteed less than 1° and this accuracy can satisfy the requirements of the simplified data processing. Post the attitude data obtained can be used to form a real-time and reliable 3D simulated interface. It provides an intuitive and reliable decision-making platform for the operator. 3D visual technology includes the establishment of OpenGL virtual scene, 3D graphics technology, graphic geometric transformation and real-time processing. The features of the technology are remote, reliable, non-destructive testing and provide an intuitive and reliable decision-making platform for the operator. When it is combined with the actual needs, a variety of functional modules can be extended, and the technology can be widely used in the monitoring process azimuth data acquisition.更多还原
