百度地图API调用转换WGS坐标以及上传点到鹰视

* 根据某个对象的经纬度和高度在百度地图上绘制出车辆的轨迹
* 首先根据离散的点，拟合出一个平滑的曲线
* 然后将采样后的曲线绘制在百度地图上
* 首先获取百度的AK : 121
* service:
* 开发者使用一个百度的service可以管理很多的电动车，每一个电动车称为一个entity，service的service_id是唯一的，开发者可以使用轨迹管理平台管理service，包括创建，编辑和查看
* entity:
* 一个设备有一个唯一的entity_name作为唯一标识，一个service最多同时管理一百万个entity，鹰眼web api提供entity的增删改查的接口
* entity column:
* entity自定义的字段，可以用于描述eneity
* track:
* entity移动产生的轨迹，由point组成，数量可以没有限制，web api提供了添加，批量添加，查询历史轨迹的接口。
* track column:
* 除了，坐标，速度，方向，定位时间等轨迹的系统字段之外，可以添加自定义的字段。例如心率，油量等等，可以自定义10个字段
* fence:
* 地理围栏，是一个区域，离开这个区域报警
* object：
* 代表图像和视频对象，支持上传图像数据，支持图像数据的存储，查询和下载
