一种针对便捷设备的观测系统快速显示方法

A fast geometry display method for portable devices

随着手机、平板电脑、手持物探装备等便携设备在物探施工中的应用,获取信息更加便捷、丰富,沟通也更及时,这极大地提高了施工效率和精度.观测系统是整个勘探施工的基础和依据.为了满足便携设备在物探施工中的显示需要,本文采用C++和QT开发了一套跨平台的观测系统显示模块.该模块可以运行在Windows、Linux和Android等多种系统平台上,可以在差异较大的便携设备上提供统一的显示服务.利用此模块可以方便地在不同设备和平台上为用户提供优质、流畅的观测系统显示服务,同时该模块具有良好的可扩展性,可以与导航、卫星背景图等结合使用,为用户提供全方位信息显示服务.

With the application of portable devices such as tablets, mobile phones and professional geophysical equipment in geophysical exploration, it is more convenient and comprehensive to obtain information in time, which greatly improves the efficiency and accuracy. Geometry is the basis of the whole exploration, in order to meet the display needs of portable equipment in geophysical exploration, this paper develops a cross-platform geometry display module with C++ and QT . which can run on Windows, Linux, Android, and provides unified geometry display services on different portable devices. A high-performance geometry display solution is formed by coordinate transformation, and mapping display data, multi-thread + dual display cache rendering, dynamic grading and other methods? The module can easily provide high quality and smooth display on different portable devices and platforms. Layers are used for display management, which can be easily extended by adding a tile layer, an obstacle layer, etc. Meanwhile, the module can be easily extended and applied in geophysical exploration such as vibroseis navigation, line test and so on, which provides users with a full range of information display services.
