很久没有更新文章了, 最近完成一项类似KEEP的运动软件.简单总结一下思想和实现方式.(因为原项目是swift,所以就用swift简单演示一下)
1. 架构.
image.png
- MVC-State数据驱动
-- Manager 业务管理器(数据管理,语音管理,运动轨迹管理)
-- Model 业务模型(数据didSet发出通知)
-- Module 业务模块(展示图表,运动主页,地图模块,排行模块,分享模块,设置模块,上传模块等等)
-- Router 业务流转路由
-- Lib 库文件
1. 实现.
SportTrackingManager.swift运动管理器通过高德定位AMapLocationManager回调方法绘制轨迹,判断GPS信号,计算运动数据.通过CMPedometer计步器校准步数,通过CMAltimeter气压计校准海拔数据,通过CMMotionActivityManager活动对象判断用户行为.
/// 定位管理
public lazy var locationManager = AMapLocationManager()
/// 计步类
private var pedometer: CMPedometer?
/// 气压计
private var altimeter: CMAltimeter?
/// 活动器对象
public var motionActivityManager: CMMotionActivityManager?
public var motionActivitystatus: CMMotionActivity?
GPS 信号策略
1.定位管理返回的精度策略
i. 如果水平精度或垂直精度均小于0 或者 水平精度或垂直精度均大于等于100 --> 认为已经失去了GPS信号
ii. 如果水平精度和垂直精度均小于等于10 --> 认为GPS信号非常的好
iii. 如果水平精度小于60 --> 认为GPS信号一般
iiii.其他情况下 --> 认为GPS信号很差
2.定位返回位置的间隔时间判断
如果当前位置点相对等待了 超过了5s --> 认为GPS信号很差
如果当前位置点相对等待了 超过了10s --> 认为GPS信号失去
@objc private func gpsBad() {
if self.gpsStatus != .Bad {
self.gpsStatus = .Bad
}
}
@objc private func gpsDisconnected() {
if self.gpsStatus != .Disconnected {
self.gpsStatus = .Disconnected
}
}
@objc private func gpsDistanceFilter() {
self.locationManager.distanceFilter = kCLDistanceFilterNone
}
// MARK:- GPS信号强弱时间判断
private func gpsPerformRequests () {
NSObject.cancelPreviousPerformRequests(withTarget: self, selector: #selector(gpsBad), object: nil)
NSObject.cancelPreviousPerformRequests(withTarget: self, selector: #selector(gpsDisconnected), object: nil)
self.perform(#selector(gpsBad), with: nil, afterDelay: 5)
self.perform(#selector(gpsDisconnected), with: nil, afterDelay: 10)
}
// MARK:- GPS信号强弱精度判断
public func gpsStatusWithCLLocation(location: CLLocation) -> SportTrackingGPSStatus {
if location.horizontalAccuracy < 0 || location.verticalAccuracy < 0 || location.horizontalAccuracy >= SportConfig.disconnectLimitAccuracy || location.verticalAccuracy >= SportConfig.disconnectLimitAccuracy {
return .Disconnected
} else if location.horizontalAccuracy <= SportConfig.bestLimitAccuracy {
return .Good
} else if location.horizontalAccuracy < SportConfig.normalLimitAccuracy {
return .Normal
} else {
return .Bad
}
}
实时定位打点轨迹策略
- 定位点时间戳与当前时间戳差值 > 1s 认为不是当前的点位 去除
- GPS信号丢失 去除
- 上一次获取点位时间戳与当前点位时间戳差值 <= 0.1s 认为在原地不动 去除
- 上一次获取点位位置与当前点位位置差值 <= 0.1m 认为原地不动 去除
- GPS获取当前点位置的速度 = 0 去除
- 自动检测当前运动类型是驾车和静止 去除
- 根据运动类型判断速度策略
行走 --最小速度 minLimitSpeed = 0.3 m/s
--最大速度 max(当前计算速度, gps返回的当前速度) > 5.5 m/s -> // 估算人类竞走最快纪录 5.5 m/s
跑步 --最小速度 minLimitSpeed = 0.5 m/s
--最大速度 max(当前计算速度, gps返回的当前速度) > 100 / 9.58 m/s -> // 目前最新百米赛跑的世界纪录是9.58 秒
骑行 --最小速度 minLimitSpeed = 0.8 m/s
--最大速度 max(当前计算速度, gps返回的当前速度) > 56 m/s -> // 公路自行车世界纪录 202km/h = 56 m/s- 当gps信号很差的时候过滤:
max(当前计算速度, gps返回的当前速度) > 300米后计算出的平均速度 * 2 如果当前计算出来的的速度跳变为当前平均速度的2倍 去除- 手动和自动暂停 去除
- 经过卡尔曼滤波处理 优化轨迹平滑度
- 三角滤波去噪抽稀
- 道格拉斯算法压缩轨迹
