Scale Calibration
Step 3: Scale Calibration
Goal: Calibrate real-world physical dimensions against photo pixels.
Instructions:
- Click Set Reference Scale and draw a line over a known feature (e.g., door height, wall width).
- Enter the real dimension in inches when prompted.
- If moderate perspective distortion exists, click Set 2nd Axis Scale for dual-axis ground-truth locking.
Pro Tip: Precise scaling guarantees accurate square footage, sign width, and height calculations in detail callouts.
Standard: Works great for straight & slight perspective photo.
Perspective Definition
Step 4: Perspective Alignment
Goal: Align 3D camera angles and rotation with the plane of the wall or fascia.
Instructions:
- Click Define Elevation Area and click 4 corners on the photo defining a wall rectangle (Top-Left, Top-Right, Bottom-Right, Bottom-Left).
- For flat straight-on photos, click Straight On to lock 2D orientation automatically.
Pro Tip: Drag corner handles anytime to adjust wall angles; all placed signs will orient in real-time.
