Unable to connect my LiDAR L515 to my Mac

[littlefred117]

Hi,

I am trying to establish a pipeline between my Mac and my LiDAR L515, and when I originally plugged the camera in, the RGB and sensor mode were working. I had to "sudo real sense-viewer" into RealSense, otherwise it would crash, but generally everything else was working. I then ran this code:

import pyrealsense2 as rs
import numpy as np

Initialize the RealSense pipeline

pipeline = rs.pipeline()
config = rs.config()
config.enable_stream(rs.stream.depth, 640, 480, rs.format.z16, 30)
config.enable_stream(rs.stream.color, 640, 480, rs.format.rgb8, 30)

Add point cloud stream

config.enable_stream(rs.stream.points, 640, 480, rs.format.xyz32f, 30)

Start the pipeline with the given configuration

pipeline.start(config)

try:
while True:
# Wait for a frame
frames = pipeline.wait_for_frames()

    # Get depth, color, and point cloud frames
    depth_frame = frames.get_depth_frame()
    color_frame = frames.get_color_frame()
    points_frame = frames.get_points()

    if not depth_frame or not color_frame or not points_frame:
        continue

    # Get the raw depth and color data as numpy arrays
    depth_data = np.asanyarray(depth_frame.get_data())
    color_data = np.asanyarray(color_frame.get_data())

    # Get the raw point cloud data as a numpy array
    points_data = np.asanyarray(points_frame.get_vertices())

    # Print raw depth, color, and point cloud data
    print("Raw Depth Data:")
    print(depth_data)
    print("Raw Color Data (RGB):")
    print(color_data)
    print("Raw Point Cloud Data (XYZ):")
    print(points_data)

    # Save the point cloud data to a file
    np.savetxt('point_cloud.xyz', points_data, delimiter=' ')

finally:
# Stop the pipeline
pipeline.stop()

and from here it stopped working. The code would not compile because it said a device was not connected. Whenever I go to my RealSense, I get these errors: UNKNOWN in rs2_get_option(options:0x600003df9400, option:Brightness): failed to set power state. I was wondering if anyone could help.

Hi @littlefred117 Could you first try unplugging the micro-sized end of the USB cable from the base of the L515 camera, reversing the connector's orientation and plugging it back into the camera, please (USB-C cables are two-way insertion at the micro-sized end). Does doing so make any difference?

[littlefred117]

That didn't work

[MartyG-RealSense]

Is the camera problem only occurring in Python or does realsense-viewer also no longer work, please?

[littlefred117]

Both, in Python my I get a runtime error that my device is not connected, and on RealSense Viewer (when I plug the device in) I get these errors:

If you did not make any installation changes before the sudden failure then it sounds as though it may be a non-fixable camera hardware failure unfortunately.

If you purchased your L515 camera within the past year then in that case I would recommend contacting the retailer that you purchased the camera from to enquire about returning it.

Hi, I'm trying the LiDAR on a new device, and the issues seem to be gone. However, when I try to - import pyrealsense as rs -, I get an issue saying there is no module named pyrealsense (even after I pip installed it).

[MartyG-RealSense]

It's great to hear that the camera worked on another device.

Do you still receive the error if you instead use the longer import instruction below:

import pyrealsense2.pyrealsense2 as rs
