Verification regulation of magnetism influencing error for the dsz05 and dsz1 compensator levels Dsz0 . 5 dsz1自动安平水准仪磁致误差检定技术规程
An auto leveling instrument system based on cmos image sensors is described in this thesis 本论文详细论述了一种基于cmos图像传感器的水准仪自动安平系统。
We believe and know that god wants to know each and every one of us on a very personal level 我们相信和知道上帝想在一个很私人的水准仪上知道每一个和我们的每一个。
In this paper , the measurement principle of various digital levels and error sources is discussed 随着数字水准仪的广泛应用，急需制订一套合理的方案以评定数字水准仪的质量。

Image processing for coded level ruler of digital levels is the critical technology to realize the automatic reading of digital levels 摘要数字水准仪编码水准尺的图像处理是实现数字水准仪自动读数的关键技术。
Because of the large difference between digital level and optical level , the suitable method to assess the precision of digital level is needed 同传统的光学水准仪相比，数字水准仪原理新颖，影响其精度的误差源也有所不同，目前还没有针对数字水准仪的检定规程。
In addition , the mcu judges whether the plate level has been a horizontal place according to these data , and then control the stepping motor to make the instrument level 单片机根据所得到的数据判断水准仪是否处于水平位置并控制步进电机将水准仪调节至水平位置。
The experiment result shows the algorithm is feasible and quick speed and high precision in operating , which provides base datum for the automatic reading of digital levels 将该并法应用于自设的数字水准仪测量实验系统，结果表明：算法切实可行，运算速度快，精度高，为实现数字水准仪自动读数提供了基础资料。
At present , four manufacturers , leica , zeiss , topcon , sokkia , introduced different models of digital levels to the surveying market with different measurement principle and code staff 目前徕卡、蔡司、拓普康、索佳四家公司相继推出了各自的数字水准仪产品，不同厂家的仪器采用了不同的电子读数原理和标尺编码结构。
