calculate distance with rplidar a3m1
how can i measurement object distance between -180 and 180 degree. I cant adjust ranges value.
import rospy
from sensor_msgs.msg import LaserScan
class LazerVerisi():
def __init__(self):
rospy.init_node("laser")
rospy.Subscriber("scan",LaserScan,self.laserCB)
rospy.spin()
def laserCB(self,msg):
front = list(msg.ranges[0:360])
For example, to get the 170th degree distance; deg170 = np.array(lidar_data.ranges[179*4])
Currently your range values begin at 0° and end at 360° and you want your ranges array to start at -180° and end at +180°. Am I understanding the question correctly?
