Access: On the Menu bar, click View > rayCloud to open the rayCloud. The right sidebar is displayed on the right of the main window.

The camera information is displayed on the right sidebar when selecting in the 3D View:

  • The initial camera position (for calibrated and uncalibrated cameras for which the initial position is known).
  • The calibrated camera position (for calibrated images).
  • The camera associated image thumbnail (for calibrated images).
The camera information is also displayed when selecting a given camera in the Layers section of the left sidebar.

 The displayed camera information is different for:


Calibrated images

The following information is displayed in the Selection section:

  • Camera: Name of the image associated to the selected camera.
  • Camera Model: Camera model associated to the selected camera, including Image size in pixels (widthxheight) and band configuration.
  • Number of Marked MTPs and GCPs: Number of Manual Te Points / GCPs marked on the image.
  • Number of Automatic Tie Points: Total number of matched keypoints found on the image.
  • Computed Position [units]: X, Y, Z computed position of the camera.

 

Buttons:

  • Disable: Disables the image. In order to remove the camera from the reconstruction, the project needs to be reoptimized. This button is shown for enabled cameras.
  • Enable: Enables the image. In order to include the camera in the reconstruction, the project needs to be reoptimized. This button is shown for disabled cameras.
  • Uncalibrate: This option should be chosen if the user is not confident about the calibration of the camera.
  • Help: Opens the Pix4Dmapper help. 
  • Apply: (available when the Image Annotation tool is used): Applies the image annotation. 

Image preview: Displays the image associated to the calibrated camera.

  • Orange cross: Represents the position of an automatic keypoint that has been matched with keypoints from other images.
  • Yellow cross: Represents a Manual Tie Point or a GCP marked on the image.
  • Right slider: Allows to select the minimum number of images with which a keypoint has been matched.
  • zoom_in.png Zoom in: Zoom in on the image. 
  • zoom_out.png Zoom out:  Zoom out of the image.
  • pencil.png Image Annotation:  Activates the Image Annotation mode.

 The Image Annotation tool includes the following: 

    • Mask: The pixels masked are not used for processing. Suitable for:
      • Removing an obstacle that appears in a few images, like a scaffold. For more information: 210748986.
      • Removing the background of the Orthoplane: For more information: 210226543.
      • (for Bebop projects) Removing the sky automatically. For more information: 205327965.
    • Carve: All the 3D points located on the rays connecting the camera center and the annotated pixels are not used for processing. Suitable for sky removal. For more information: 212262883; 212262943.
    • Global Mask: The pixels annotated are propagated to all the images. All these pixels are not used for processing. Suitable for a consistent obstacle on all the images, e.g. the foot of the drone. For more information: 210749586.
 
Tip: For the selected image:
  • In order to zoom in/out: Place the mouse over the location on which to zoom, and move the mouse scroll button forwards/backwards.
  • In order to pan: Place the mouse over the location on which to pan, and press the left mouse button while dragging the mouse.
  • By placing the mouse over an image and typing space, the image is displayed in full screen, where is possible to zoom, pan, click, etc.
  • When using the full screen mode, by typing:
    • Space: Minimizes the image and keeps the full screen zoom and panning level.
    • Esc: Minimizes the image and keeps the previous zoom and panning.

 

Images section

When double clicking on a cross in the Image preview (Automatic/Manual Tie Point or GCP), the Images section displays the images where the point can be found (including the currently selected image). For more information: 202558459.

 

Uncalibrated images

When selecting an uncalibrated camera, it can be manually calibrated.

The following information is displayed in the Selection section:

  • Camera: Name of the image associated to the selected camera.
  • Camera Model: Camera model associated to the selected camera, including Image size in pixels (widthxheight) and band configuration.
  • Number of Marked MTPs and GCPs: Number of Manual Te Points / GCPs marked on the image.
  • Number of Automatic Tie Points (Inliers/Total): Inlier points and total number of matching keypoints found on the image.
  • Computed Position [units]: X, Y, Z position of the computed camera. Since there is no computed position, it appears as n/a.

 

Buttons:

  • Disable: Disables the image. In order to remove the camera from the reconstruction, the project needs to be reoptimized. This button is shown for enabled cameras.
  • Calibrate: Allows to calibrate an uncalibrated camera. This button is enabled only if more than 20 Manual Tie Points and Automatic Tie Points are considered as being inliers.
  • Close: Exits the manual calibration mode.
  • Help: Opens the Pix4Dmapper help. 
  • Apply: (available when the Image Annotation tool is used): Applies the image annotation.
 
Note: For step by step instructions about how to calibrate a camera: 202560189.

 

Image preview: Displays the image associated to the uncalibrated camera.

  • Red cross: Represents the position of an automatic keypoint that was not matched with keypoints of other images.
  • Orange crosses: Represents the position of an automatic keypoint which has a high probability of being accurately matched with keypoints of other images.
  • Yellow crosses: Represents a Manual Tie Point or a GCP marked on the image.
  • Right slider: Allows the user to select the minimum number of images with which a keypoint could be matched. 
  • zoom_in.png Zoom in: Zoom in on the image.
  • zoom_out.png Zoom out: Zoom out of the image.
  • pencil.png Image Annotation:  Activates the Image Annotation mode.

    • Esc: Minimizes the image and keeps the previous zoom and panning.

 

Tie Points section: Displays in a table information about the Manual Tie Points and GCPs that are marked on the selected image. The table allows to edit the information about the Tie Points by double clicking on the corresponding cell. For detailed information: 202557919.

  • Apply: When clicking on this button, the new marks or changes for the displayed Manual Tie Points and GCPs are added to the project.

 

Images section

When double clicking on a cross in the Image preview (Automatic / Manual Tie Point or GCP), the Images section displays the images where the point can be found (including the currently selected image). For more information: 202558459.
