我有一个 python 脚本来运行激光雷达传感器。它测量距离。我在伺服电机的帮助下移动激光雷达。所以我必须以不同的角度测量距离。我正在尝试用角度和距离更新字典。但是字典总是显示错误的角度值。

下面给出部分代码。任何类型的建议都会非常有帮助

    angle_start =0
    angle_step = 2    #degree step     
    self.set_angle(angle_start)   #a method to set servo angle
    time.sleep(pos_time) 

    angle_dict = {}          #an empty dict
    angle=angle_start
    while angle <= angle_stop:

        self.set_angle(angle)
        time.sleep(0.05)

        distance = int(self.messure_distance())    #a method to measure the distance. it works fine.
        angle_dict[angle] = distance       #trying to update the dict. it stores right distance. but now the right angle.

        angle = angle + angle_step              #increasing angle
