MapElement Module FAQ

Detect Lane Line

  1. [Warning] "This file does not have intensity information"
    • Warning Reason: The current point cloud does not have intensity information.
    • Solution: Automatically skip point clouds without intensity information, no action required. You can manually check if the intensity information of the point cloud file is correctly saved.
  2. [Warning] "Current action is not supported under ortho editing"
    • Warning Reason: Lane lines do not support orthographic view editing.
    • Solution: Turn off orthographic view editing.
  3. [Error] "Seed Point Z is NOT correct! Please Repick" or "The seed is Not Correct! Please repick"
    • Warning Reason: The seed point is incorrect.
    • Solution: Switch views to ensure the seed point is selected on the lane line.

Detect Road side Line

  1. [Warning] "Can not switch handler, please use the space bar to stop first"
    • Warning Reason: Manual operation mode cannot be switched during detection.
    • Solution: Press the Space bar to stop automatic detection first, then switch operation modes.
  2. [Error] "Seed Point Z is NOT correct! Please Repick"
    • Warning Reason: The seed point is incorrect.
    • Solution: Switch views to ensure the seed point is selected on the pavement near the curb.

Generate Virtual Lane Centerline

  1. [Warning] "Failed to generate Virtual Lane Centerline"
    • Warning Reason: The selected lane line geometry is incorrect, and centerline generation failed.
    • Solution: Check if the selected lane line geometry has errors: fewer than 2 points, backtracking, or incorrect internal point order.

Road Marking Training

  1. [Warning] "Please draw symbol with three or more points"
    • Warning Reason: The number of points in the created template is too few.
    • Solution: Ensure the number of template points is greater than or equal to three.
  2. [Warning] "Please draw symbol"
    • Warning Reason: The template has no valid points.
    • Solution: Ensure the number of template points is greater than or equal to three.
  3. [Warning] "Data Open Failed"
    • Warning Reason: The data file being imported is corrupted, causing the data to fail to open.
    • Solution: Check if the data file is correct and reselect the data file.
  4. [Warning] "Template.db file version is too high"
    • Warning Reason: A lower version of the software opened a .db database file used by a higher version of the software.
    • Solution: Lower version software cannot use .db files from higher version software; please use the higher version software.
  5. [Warning] "Template.db file error"
    • Warning Reason: The .db database file is corrupted.
    • Solution: Replace the database file.

Road Marking Auto Matching

  1. [Warning] "This file does not have intensity information"
    • Warning Reason: The current point cloud does not have intensity information.
    • Solution: Automatically skip point clouds without intensity information, no action required. You can manually check if the intensity information of the point cloud file is correctly saved.
  2. [Warning] "Failed to open DB file"
    • Warning Reason: The database file is corrupted.
    • Solution: Replace the .db database file.
  3. [Warning] "No corresponding model found"
    • Warning Reason: The model file is missing or corrupted.
    • Solution: Use the road sign training function to retrain and generate the corresponding model file.
  4. [Warning] "Template.db file version is too high"
    • Warning Reason: A lower version of the software opened a .db database file used by a higher version of the software.
    • Solution: Lower version software cannot use .db files from higher version software; please use the higher version software.
  5. [Warning] "Template.db file is incorrect!"
    • Warning Reason: The .db database file is corrupted.
    • Solution: Replace the database file.
  6. [Error] "Error: Init Model Failed!"
    • Warning Reason: Error initializing the deep learning model.
    • Solution: GPU mode requires certain hardware specifications; try using CPU mode. If errors persist in CPU mode: 1. In self-training mode, the model file may be corrupted and needs retraining to regenerate the model file. 2. For built-in models, reinstall the software or contact technical support.
  7. [Error] "Failed to Create SymbolDataBase"
    • Warning Reason: Failed to create a new .db database file.
    • Solution: Choose a different location and try again. If it still fails, reinstall the software or contact technical support.
  8. [Error] "ERROR: Failed to access class name" or "ERROR: Failed to access class name path:"
    • Warning Reason: Error with files required for deep learning.
    • Solution: 1. In self-training mode, the model file may be corrupted and needs retraining to regenerate the model file. 2. For built-in models, reinstall the software or contact technical support.
  9. [Error] "DB file is not correct"
    • Warning Reason: The .db database file is corrupted.
    • Solution: Replace the database file or reinstall the software.
  10. [Error] "Table name does Not Match!"
    • Warning Reason: The selected model table does not match the records in the .db database file.
    • Solution: 1. Select a different model table. 2. Replace the database file.
  11. [Warning] "Points is empty"
    • Warning Reason: The number of point cloud points within the range is too few.
    • Solution: Reselect to ensure the selected polygon is on the pavement and that the internal ground printing block points are clearly visible.

Road Vector

  1. [Error] "RoadMarkingLane Model init failed"
    • Warning Reason: The lane line model file is missing or corrupted, causing initialization failure.
    • Solution: Reinstall the software or contact technical support. Automatic recognition of lane lines is not possible, but it does not affect the automatic recognition of arrows, crosswalks, and other ground printing blocks.
  2. [Error] "Box Mode init failed" or "Key Points Model init failed" or "Error: Init Model Failed!"
    • Warning Reason: Model initialization failed.
    • Solution: GPU mode requires certain hardware specifications; try using CPU mode. If errors persist in CPU mode: 1. In self-training mode, the model file may be corrupted and needs retraining to regenerate the model file. 2. For built-in models, reinstall the software or contact technical support.
  3. [Error] "Error: lane model is none, please re-init lane model"
    • Warning Reason: The lane line model file is missing or corrupted, causing initialization failure.
    • Solution: Reinstall the software or contact technical support. Automatic recognition of lane lines is not possible, but it does not affect the automatic recognition of arrows, crosswalks, and other ground printing blocks.

    • Solution: Reselect the json folder.
  8. [Warning] "Intensity image coordinate file folder does not exist"
    • Warning Reason: In custom mode, using json and intensity images, the corresponding coordinate folder for the intensity image was not found.
    • Solution: Data materials are missing; regenerate the data materials.
  9. [Warning] "No valid intensity image coordinate file (.xml)"
    • Warning Reason: No .xml format coordinate file was found in the corresponding coordinate folder for the intensity image.
    • Solution: Data materials are missing; regenerate the data materials.
  10. [Warning] "Cannot access ... .json coordinate file"
    • Warning Reason: No corresponding .json file was found in the coordinate folder for the intensity image.
    • Solution: Data materials are missing; regenerate the data materials.

Generate Intensity Image

  1. [Warning] "Not enough memory"

    • Warning Reason: Too few points to generate an image.
    • Solution: No action required, this is just a notification.
