Pisa: inclination analysis software and mechanical bending.

In Pisa you can analyse the danger of collapse or rupture of structures such as poles of power distribution networks.

The system can optionally be integrated with MobileReport so your employees, contractors and the general public can submit reports of potentially dangerous structures.

Example Usage: Analysis of the Leaning Tower of Pisa

Note: The red line follows the left side of the tower, the green line is on the edge of a vertical structure.

Tower of Pisa

Structure

Segment 1: (26.5, 345.5, 0.0) over 346.51 px

Vertical

Segment 1: (2.0, 272.5, 0.0) over 272.51 px

Vertical angle 3.97 °

Pisa Factor 99.39%

Note: there is a small error (-0.02 °) compared to the actual value, it may be because the picture is not taken from the point of view where the maximum slope occurs.

Benefits

In less than a minute the software can

  • Calculate the tilt angle accurately
  • Determine the bending

Diagnose that posts should be strengthened (using stays or reinforcements)

Integrates with MobileReport system

Operation

  1. Load a photo in the application.
  2. The user draws lines over the structure that is tilted by the center or an edge (in red).
  3. The user draws a line over the reference structure that is considered vertical (green).
  4. The software calculates the inclination angle and the bending arrow

Total time for operation: 45 seconds

Note: The time to take the picture is not included

Applications

  • The leaning tower of Pisa
  • Posts of the energy distribution networks
  • Compliance with the standard such as RETIE
  • Analyse the danger of tipping or rupture
