鹰眼轨迹分析类接口提供停留点分析和驾驶行为分析功能：

1. 停留点分析接口：一段轨迹中有多少个停留点、停留在何处、停留了多久
2. 驾驶行为分析：一段轨迹中有多少个超速点、急加/减速点、急转弯点，其中超速点功能支持依据百度地图路网实际道路限速计算，也支持开发者设置固定的限速值

注意： 如使用轨迹分析相关接口，轨迹点上传时请务必同步上传speed(速度)和direction(方向)字段，否则该接口将不进行分析计算。鹰眼SDK在GPS定位下会自动采集这些数据。

目前中国主要有以下三种坐标系：

WGS84：为一种大地坐标系，也是目前广泛使用的GPS全球卫星定位系统使用的坐标系
GCJ02：是由中国国家测绘局制订的地理信息系统的坐标系统。由WGS84坐标系经加密后的坐标系
BD09：为百度坐标系，在GCJ02坐标系基础上再次加密。其中bd09ll表示百度经纬度坐标，bd09mc表示百度墨卡托米制坐标

非中国地区地图，统一使用WGS84坐标

查询entity在指定时间段内的停留点。停留点判断规则为：在stay_radius半径范围内，滞留stay_time以上，被认为是一次停留，将取一个代表性坐标作为停留点，其中 stay_radius 默认为20米，stay_time 默认为 600秒。

查询entity在指定时间段内的驾驶行为，返回以下分析结果：
1. 总体信息：起终点信息、里程、耗时、平均速度、最高速度
2. 异常信息：超速、急加速、急刹车、急转弯
