description: "Train a model on the utility own insulator photos so it can mark likely cracks, chips, broken discs, flashover burn marks, heavy contamination and missing hardware. Each mark is tied to the structure and photo it came from, so a qualified line inspector can review the image, confirm or reject the mark, and decide on any repair. The model only sorts and flags photos; it never sets repair priority or clears a structure on its own, and all field work follows the utility safety and access rules."

# How can a utility use computer vision to review insulator photos from drone and line patrols?

Train a model on the utility own insulator photos so it can mark likely cracks, chips, broken discs, flashover burn marks, heavy contamination and missing hardware. Each mark is tied to the structure and photo it came from, so a qualified line inspector can review the image, confirm or reject the mark, and decide on any repair. The model only sorts and flags photos; it never sets repair priority or clears a structure on its own, and all field work follows the utility safety and access rules.

## What this means in practice

- Gather a set of insulator photos from past patrols that inspectors have already reviewed
- Label the defect types the inspection program cares about, plus clear examples of healthy insulators
- Run new patrol photos through the model and group the marks by structure and line section
- Have a qualified inspector confirm or reject each mark and record the decision
- Feed confirmed and rejected marks back into training so the model improves on the utility own equipment

## How Lid Vizion approaches it

We start with the business decision and operating context, define ownership and measurable milestones, then use configuration, integrations, automation, or custom software only where each earns its place.
