Keeping a nation’s lights on means constantly inspecting electricity poles
for damage. Before EDP partnered with DefinedCrowd, teams of specialists
had to jump into helicopters, survey and photograph poles from way up in
the sky and use those photographs to manually fill out damage reports when
the day was done. That’s a slow, expensive process with a lot of moving
parts to answer a simple question: “which of our poles needs fixing?”
The Challenge
As a proof-of-concept, we first delivered
a model capable of identifying electricity poles
and their components (insulators and crossbars.
That meant gathering 12,500 images — 7,000
with poles — that were then annotated
by our highly-skilled Neevo community
(45,000+ strong). We used 3,000 of those
images to train a pole detection model
and 500 more to test it.
Our Solution
Next, we built damage detection models
by hand-selecting a subset of 900
high-resolution images and sending them
out to our Neevo workforce. They identified
the type of damage in each, and then
we used those annotated images to train
and test one model to keep track of
damaged or missing insulators and another
to detect corrosion on crossbars.
Step 1
Pole Detection
Step 2
Damage Detection
With these models, EDP is on the path to faster, cheaper, and more accurate
asset management processes (APM). In the short-term, that means drones
will feed high-quality images of poles into automated systems that will
deliver comprehensive damage reports as a result. In the long-term,
automated APM will allow EDP to ask and answer more sophisticated
maintenance questions. The corrective present, “which poles need fixing?”
will be replaced by the predictive future, “which of our poles will
need fixing?”
