获取intel D435i 深度图像的深度距离单位

# Retrieves mapping between the units of the depth image and meters.
pipeline = rs.pipeline()
config = rs.config()
profile = pipeline.start(config)
# 返回深度单位
depth_sensor = profile.get_device().first_depth_sensor()
depth_scale = depth_sensor.get_depth_scale()

print("Depth Scale is: " , depth_scale)
