visual measurement meaning in Chinese
目测
Examples
- Firstly , this paper expounds some basic image processing concepts that is frequently used in the visual measurement of space robot . , studies and analyzes ordinary methods about image processing , which include image pretreatment , image segmentation and edge detection
首先,阐述了空间机器人视觉测量中常用到的一些图像处理的基本概念,研究和分析了目前较常用的图像预处理、边缘检测、图像分割等算法。 - Thus the areas of the overlapping regions are compensated efficiently and the accuracy of measurement is highly improved . the volume of the bubbles can be estimated on the bubbles " area information , and a genetic algorithm ( ga ) based method is used to match and track bubbles in the image sequences , which solve tracking problem under complex conditions efficiently , such as some bubbles may have kinetic occlusion and crossover , some newly generated bubbles may entered into flow field and run away . a smooth kinetic locus is obtained by fitting the discrete centroids with a cubic spline function and at the same time the visual measurement is realized
根据气泡在图像平面中的面积估计气泡的体积，并对流场中的所有气泡采用遗传算法进行最佳的匹配跟踪，有效地解决了气泡群在流场中出现如遮挡、交又、新它‘出现、逃逸等复杂情况下的准确跟踪，并采用三次样条插值方法对离散的质心点轨迹进行拟合，得到气泡在流场中平滑的运动轨迹，从而实现了掺气水流特性的可视化测童。
