未知环境下的Lidar概率占位栅格图(Occupancy Grid Map) Python代码实现

theta = X[2] meas_r = rmax * np.ones(meas_phi.shape) # Iterate for each measurement bearing 主要流程是: 1)将 Lidar bearing与Map Cell相对于传感器的方位进行最小误差匹配,得到影响当前Map Cell的激光束; 匹配的代码如下: r = math.sqrt((i - x math.pi) % (2 * math.pi) - math.pi # Find the range measurement associated with the relative bearing M, N)) for i in range(num_rows): for j in range(num_cols): # Find range and bearing math.pi) - math.pi # Find the range measurement associated with the relative bearing

    ,样本共有四个维度,测试集共有20480个样本,第一张图是测试集的quantization error随时间的分布,第二张图的原理如下,每个样本都可以计算出一个最异常维度,如样本 的最异常维度是Bearing 1,样本 的最异常维度是Bearing 2,...。 20480个样本都有其最异常维度,那么每个维度都有其样本数,这便是第二张图的绘制原理,通过这张图我们可以得知此次机器的寿命问题主要因为Bearing 3。

    2D Lidar模型 它在2D平面上进行扫描,包含两个参数:Scanner bearing和Scanner rangers。 Scanner bearing均匀的分布在 image.png 之间,一般的我们可以认为它们均匀分布在360度的各个方向上。 然后通过2D Lidar bearing与Map Cell相对于传感器的方位进行最小误差匹配,得到影响当前Map Cell的激光束。
