规划驾车路线和途径点及判断车辆路线偏移

2020-02-24 18:48:34

参考地址规划驾车路线和途径点及判断车辆路线偏移

仅供参考，我还是推荐用矩形判断，嘿嘿。

star: 项目需求需要利用百度地图构建路线并支持设置途径点，以及可以实时监控车辆是否偏移路线；两种方案。

写了比较完整的注释了，替换ak可直接看效果，规划驾车路线和途径点及判断车辆路线偏移源码：

Vue子组件调用父组件的方法
下面有三种方法，我自己重点推荐第一种，毕竟这种简单粗暴好用好理解，不过这个有一个弊端，再组件嵌套组件的时候，尤其是用第三方组件里面调用自己的子组件的时候，其实已经是孙子组件了，这个时候就要parent.parent。。。。,这样就不好了，我们就得考虑其他方法了，具体怎么判断是父组件，还是爷爷组件，我会单独出一篇文章讲述。

计算一个多边形的重心点坐标（准确版）
在之前的《如何判断一个多边形是否合法》一文中有提到，用无人机规划飞行路线前，往往需要框选一个多边形的区域。而在地图控件上显示这个多边形区域时，往往会遇到这样一个需求：需要把所要测绘的多边形区域移动到地图中心。实现这个需求的基本思路就是：获取到多边形区域的重心点坐标，然后利用地图控件的 setCenter方法，就可以把地图的显示中心移动到多边形区域重心了。那么问题来了，如何求出一个多边形的重心点坐标呢？

如何判断一个多边形是否合法
利用无人机对一片区域进行测绘前，我们会先在地图上框选一个区域，然后再规划飞行的路线，而需要测绘的这片区域往往是一个多边形。在 MeshKit 中，我们加入了多边形区域的编辑功能，其中就涉及判断用户所编辑出来的多边形是否合法的问题。

百度地图做电子围栏总结
在地图上画出围栏，设置围栏信息后保存，生成围栏列表。全选时，地图视野可看到全部的围栏区域，单独勾选会调整地图视野到当前勾选的围栏。围栏区域的中心点要显示围栏名称。

图片连接处出现白线
block导致，只要父元素设置font-size：0或者设置img display: block; 便可。但是我设置了没有用，这条线不是所有的机型都有，而且页面滚动之后又消失，我琢磨半天，各种尝试，发现把图片高度减少（增加）1px就解决了。因为我们的项目是用postcss-px-to-viewport，我每张图片都是设置高度的，应该是数值转换出现偏差。

粗略计算多边形中心点（并不是很准确，但简单好用）
也是再做栅栏系统，搜索如何获取多边形中心点的问题上，发现了这个，简单易于理解，但是并不是特变准确，但也不影响使用。后来发现了新的算法，并且百度地图也提供相应的api。具体内容我写在了前面的文章，大家可以找一下。

vue,vuthis.$parent算法
由于组件嵌套，其实vue parent的位置也改变了，我们可以通过下面的图片，来看一下，parent到底什么哪一层

百度地图多个标记点设置最佳视角
通过下面的语法，我们可以为不规则图形，以及过大的图形进行地图适配，更好的展示我们画的图形，当然，如果展示所有的图形，我们可以暴力的把所有的点组合起来进行展示，点过多不知道会不会影响性能，不过我们也可以从后台精简点数，不过地球是圆的，不知道好不好做。
