线状要素的英文
line feature
linear feature
例句与用法
- Under the premise of ensuring its accuracy of point positions , not only is vector data obtained but its compressing is also realized with a quicker speed , more accuracy and smaller storage device
该方法在确保点位精度前提下，可获得以弧段为单位的矢量数据，同时依据线状要素的形态取样，从而达到压缩数据目的，此算法处理速度快，精度高、存储量小。 - Based on the wavelet theory , the relation between multiresolution analysis and multi - scale data expression in gis is found , a new model of using multiresolution analysis is put forth , and the application example to use the proposed model is given in this paper
本文应用小波理论建立了多分辨率分析与gis图形数据多比例尺表达的关系,在此基础上提出了一种基于多分辨率分析的自动制图综合模型,并以线状要素自动综合为例,说明了新模型方法的应用。 - The paper , in the way of math morphology , manages to classify the linear elements , the same type but different width in the scanning , and result in the two - valued linear image in the same level . in the fine division of the target image , a way of math morphology based on the double structure of cell stencil is put forward , which prevents the terminals and the acnodes from losing and also reduces effectively time in doing so . as the result of the framework of the fine division , vector method is formed in which its track is monitored by using dynamic change of pace about freeman ' s chain code
本文用数学形态学相关理论方法实现了对扫描图像中具有同一线型但不同线宽的线状要素进行分类，在同一层上得到同一线宽的二值线状要素图；在对此目标图像进行细化时，提出了基于双结构单元模板的数学形态学细化算法，用该算法对实际的线状要素进行细化，避免了端点、孤立点等信息的丢失，且由于是并行处理，有效地提高细化速度；对于细化后的骨架线，提出了基于freeman链码的动态改变步长保持精度跟踪矢量化方法。 - ( 2 ) discuss how to use the information from rs to distill the environmental geologic factors discuss the method for distill the surface sink , landslip , etc . from dtm , water , residential area , vegetation , gold mine points , gangue warehouse , etc . from spectrum analysis , roads , ground split , falls , etc . from crisp and eye distinguish
