Menu: View / Spherical images

It is possible to incorporate spherical images into VisionLidar by specifying an images folder and loading a position file to accurately place the images in the project.

To begin with, specify the folder where the images are stored in the Images folder. Next, select Load Path 

Version française

VisionLidar allows users to integrate spherical images into their projects, accurately positioning them based on a position file. These images enhance visualization by aligning real-world images with the point cloud data.

Uploading Spherical Images

To add spherical images to the project:

  1. Navigate to the “Upload Images” tab.

  2. Click “Select Files” to load the TXT or CSV position file

which is

  1. associated

to

  1. with the images

- this file should include the file name, timestamp, position and orientation. If many path files are being used, be sure to check the Append to existing option.

Each image can be expanded by clicking on the "..." button. Here it is possible to view the image’s GPS time for the image and the angle values for roll(Rot X), pitch(Rot Y) and yaw(Rot Z). These can be modified as needed to adjust the image to the point cloud.

A toolbar displays a few options for managing the spherical images in the list.

    • The position file must include:

      • File Name

      • Timestamp

      • Position (XYZ coordinates)

      • Orientation (Rotation values)

  2. If the software cannot automatically find the image folder, it will prompt you to manually select the “Images Folder”.

Managing Spherical Images

A toolbar provides several options for organizing and modifying the spherical images:

  • Colorize the point cloud from the images
  • Photogrammetry
  • Convert Images

    • Note: When viewing spherical images, the user is locked in the position of the image and cannot move freely as when viewing the point cloud. To exit spherical image viewing mode, either click on the ESC key or perform a right click in the main screen.

    Once the images are loaded, each image is positioned on the main screen with an annotation pin. This pin displays the position of the image as well as the direction of the trajectory. Double click on

    alignment based on the image positions.

    Image Added

    Rotates selected images based on predefined parameters.

    Image Added

    Saves the image path data as a .TXT file.

    Projection and Conversion

    • Allows conversion of image positions during import.

    • Source Projection should match the original scan units.

    • Destination Projection should match the current project units.

    3. Working with Spherical Images

    Interacting with Spherical Images

    • Once loaded, each image is represented by an annotation pin in the main view.

    • The pin shows the image position and trajectory direction.

    • Double-click the pin to open the image, or

    click on

    • use the

    Show Image Removed

    • Show icon in the image list

    next to the desired image. Afterward, browsing from image to image can be either done by double clicking on

    • .

    Navigating Between Images

    • Move between images by:

      • Double-clicking the next pin in the main window

    or going to the next or previous image (or group of images of which some are skipped). The "<<" and ">>" buttons allow to go from image to image thus afterwards automatically changing the timestamp specified in the "Time" field.

    The "Show points" option will force points to appear over the image regardless of transparency.

      • Using the “<<” and “>>” buttons to cycle through images.

      • Adjusting the timestamp in the “Time” field.

    Displaying Points Over Images

    • Show Points – Ensures point cloud data appears over the image, regardless of transparency settings.

    4. Additional Tools for Spherical Images

    VisionLidar includes advanced tools for working with spherical images:

    See the respective sections for more details on these tools.

    5. Exiting Spherical Image Mode

    • Users are locked in the image’s position while viewing spherical images.

    • To exit spherical image mode:

      • Press ESC.

      • Right-click anywhere in the main screen.
