Symbols and Colors - PIX4Dmatic

PIX4Dmatic uses a standard color scheme for symbols, enabling quick interpretation of their status. Understanding these color indicators helps to quickly assess the quality of calibration and marks.

 

Tiepoints (GCPs, Checkpoints, Manual Tie Points)

  • Blue - Indicates the initial GCP position as read from the GCP file.
  • Green - Indicates the computed position of a GCP or MTP after the calibration or reoptimization step has been completed.
  • Gray - Checkpoint position as extracted from the GCP file.

3D Blue tie point. Initial position.

3D Green tie point. Computed position.

3D Gray tie point. Checkpoint extracted from file.

2D blue tie point. Initial position.

2D green tie point. Computed position.

2D gray tie point. Checkpoint extracted from file.

Intersection Tie Points

  • Green 3D icon - aITPs or mITPs in the 3D viewer.
  • Green intersection tie point - automatic intersection tie point (aITP).
  • Yellow intersection tie point - manual interesting tie point (mITP).

3D ITP icon.  Can be either an aITP and mITP.

Green ITP. Represents aITP.

Yellow ITP. Represents mITP.

Cameras

  • Blue - Indicates the initial position of a camera as extracted from the image Exif, or image geolocation file.
  • Green - Indicates a computed position of a camera after the calibration or reoptimization step has been completed.
  • Orange - Uncalibrated camera position (failed to calibrate).

3D blue camera position. Initial position.

3D green camera position. Calibrated position.

3D orange camera position. Uncalibrated camera.

2D blue camera position. Initial position.

2D green camera position.  Calibrated postion.

2D orange camera position.  Uncalibrated camera.

Image viewer marks (lower left corner of image)

  • No mark - Indicates a pre-calibrated image
  • Green checkmark - Indicates image was calibrated.
  • Orange exclamation mark - Uncalibrated image (failed to calibrate).

No mark. Pre-calibrated image.

Green checkmark in lower left. Calibrated image.

Orange exclamation mark in lower left. Uncalibrated image.

Rays

  • Blue - Initial position of GCP or Checkpoint before the calibration step.
  • Green - Calibrated position of a 3D object after calibration or reoptimization steps.
  • Yellow - Indicates which images had GCPs/MTPS/Checkpoints that were manually marked and indicates which images had ATPs automatically marked by the software.
  • Magenta - Indicates images containing marks deemed as outliers.

Blue rays. Initial position of tie point.

Green rays. Calibrated position of tie points.

Yellow rays.  Indicates which images had GCPs/MTPS/Checkpoints that were manually marked and indicates which images had ATPs automatically marked by the software.

Magenta rays - Indicates images containing marks deemed as outliers.

Image Marks (GCPs, Checkpoints, Manual Tie Points)

  • Blue - GCP initial position on the image according to the GCP file.
  • Yellow - GCP user-defined mark on the image.
  • Green - GCP projected mark on the image after calibration or reoptimization.

Blue image mark - GCP initial position on the image according to the GCP file.

Yellow image mark - GCP user-defined mark on the image.

Green image mark - GCP projected mark on the image after calibration or reoptimization.
