拉伸测试可用于获取诸如极限抗拉强度、屈服强度、拉伸长度和弹性模量等数据。这些材料特性可用于对材料进行表征,从而确定材料是否适合给定的应用。 拉伸测试基础知识:观看此简单拉伸测试的简短演示视频。
你可以将地标视为知名建筑物或较小的物体,如树木、岩石或其他特征。 我们的robot类有一个make_landmarks函数,它会随机生成指定地标数量的位置。尝试更改num_landmarks或多次运行此单元格,查看这些地标出现的位置。我们必须将这些位置作为第三个参数传递给display_world函数,并访问地标位置列表,这个类似于我们寻找机器人...

After testing and comparing the accuracy of these 3 models, the mean error between the real location and the estimated position of landmarks on the x-axis came out to be 3.4 mm, 3.1 mm, 2.7 mm and for y-axis came out to be 3.5 mm, 2.6 mm, 2.0 mm for the 3 methods respectively...
