### 一.前提知识
|
|
||||||
|
|
||||||
##### 数据格式
|
|
||||||
|
|
||||||
- IMU:线性加速度、角速度、时间戳。
|
|
||||||
- uwb:位置、时间戳。
|
|
||||||
- LightHouse:位置、姿态四元数、时间戳。
|
|
||||||
- 融合数据:位置、姿态四元数、平面速度、角速度。
|
|
||||||
|
|
||||||
##### Lighthouse
|
|
||||||
|
|
||||||
在机器人定位系统中,"lighthouse" 通常指的是一种基于光学的定位技术,它广泛应用于虚拟现实 (VR) 系统中,例如HTC Vive的定位系统。这种技术被称为“Lighthouse Tracking System”。
|
|
||||||
|
|
||||||
**Lighthouse Tracking System 的工作原理**
|
|
||||||
|
|
||||||
1. **基站发射信号**:
|
|
||||||
- 系统包括多个基站(通常是两个),它们被放置在房间的不同位置。
|
|
||||||
- 基站会发射红外激光和同步闪光信号。
|
|
||||||
|
|
||||||
2. **激光扫描**:
|
|
||||||
- 基站中的激光会沿水平和垂直方向扫描整个房间。
|
|
||||||
- 基站发射的激光束以已知的频率和角度扫描。
|
|
||||||
|
|
||||||
3. **传感器接收信号**:
|
|
||||||
- 被追踪的物体(例如VR头显或控制器)上安装了多个红外传感器。
|
|
||||||
- 当激光束扫过传感器时,传感器会记录激光束到达的时间。
|
|
||||||
|
|
||||||
4. **计算位置和方向**:
|
|
||||||
|
|
||||||
- 激光扫描一个完整的周期需要已知的时间(例如,假设为 T)。
|

||||||
##### 卡尔曼滤波
|
|
||||||
|
|
||||||
卡尔曼滤波是一种线性二次估计算法,能够在存在噪声和不确定性的情况下,通过对状态变量的动态估计,得到系统的最优估计。
|
|
||||||
|
|
||||||
**卡尔曼滤波的基本步骤**
|
|
||||||
|
|
||||||
卡尔曼滤波器的操作过程可以分为两个阶段:预测阶段和更新阶段。
|
|
||||||

### 二.主要源文件
|
|
||||||
|
|
||||||
- type.h
|
|
||||||
|
|
||||||
**主要功能**:存储定位过程中的各种数据格式。
|
|
||||||
|
|
||||||
**示例**:
|
|
||||||

|
|
||||||
{
|
|
||||||
Imu_data imu_data_;
|
|
||||||
double pose_[3];//位置
|
|
||||||
double quat_[4];//姿态四元数
|
|
||||||
double vxy_;//平面速度
|
|
||||||
double angle_v_;//角速度
|
|
||||||
Imu_odom_pose_data(){};
|
|
||||||
Imu_odom_pose_data( Imu_data imu_data,double x,double y,double z, double qw, double qx, double qy, double qz,double vxy, double angle_v):imu_data_(imu_data),pose_{x,y,z},quat_{qw,qx,qy,qz},vxy_(vxy),angle_v_(angle_v){};
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
- IMU数据结构体:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
struct Imu_data
|
|
||||||
{
|
|
||||||
ros::Time imu_t_;
|
|
||||||
double a_[3];//线性加速度
|
|
||||||
double w_[3];//角速度
|
|
||||||
Imu_data(){};
|
|
||||||
Imu_data(double ax,double ay,double az, double wx, double wy, double wz)
|
|
||||||
:a_{ax,ay,az},w_{wz,wy,wz}{};

|
||||||
- uwb.cpp
|
|
||||||
|
|
||||||
**关联头文件**:uwb.h
|
|
||||||
|
|
||||||
**头文件重要参数**:UWB数据对象、互斥锁、基站信息。
|
|
||||||
|
|
||||||
**主要功能**:初始化一些用于定位的锚点(Anchor)的位置信息;初始化用于定位计算的矩阵,通过串口读取UWB设备的数据,对读取到的距离数据进行校正,去除高度差的影响,利用校正后的距离数据和预设的锚点位置,计算目标点的二维平面坐标。
|
|
||||||
|
|
||||||
**UWB定位算法原理:**
|
|
||||||
|
|
||||||
UWB(超宽带)定位算法主要通过测量目标点到多个已知位置的锚点的距离,利用几何方法来计算目标点的位置:
|
|
||||||
|
|
||||||

|
|
||||||
A=\begin{pmatrix}
|
|
||||||
2(x_2 - x_1)& 2(y_2 - y_1) \\
|
|
||||||

|
|
||||||

|
|
||||||
\\
|
|
||||||

|
|
||||||
d_2^2 - d_1^2 + x_1^2 - x_2^2 + y_1^2 - y_2^2\\
|
|
||||||
d_3^2 - d_1^2 + x_1^2 - x_3^2 + y_1^2 - y_3^2
|
|
||||||
\end{pmatrix}
|
|
||||||
\\

|
|
||||||
x\\
|

|
|
||||||
}
|
|
||||||
//通过多项式校正原始测量距离的非线性误差。
|
|
||||||
d[0] = ((((4.9083e-07 * d[0]) - 4.6166e-04) * d[0]) + 1.0789) * d[0] + 5.4539;
