Remote Visual Inspection

Context

The data science team at a large energy operator in APAC decided to use computer vision to improve the process of remote visual inspection of power grids.

Images are collected by drone operator teams and foot patrols in the fields. They are manually reviewed by trained engineers to identify defects. The footage from a single tower generates GBs of data, takes days to analyze, and is prone to error.

With minimal resources - an open-source data versioning tool, GPU, data storage, serving infrastructure, and notebooks - the DS team completed an initial POC. They then needed to evaluate the benefits of using CV for review teams in a 3-month pilot with new field data sets.

why choose us
model monitoring icon

From 1 month to 1 week to iterate on a model.

experiment tracking icon

+33% of time spent by data scientists on high-value tasks.

From 100% to 50% of images manually reviewed. Only 30% of false positives.

Challenge
1
Ensure consistency across different conditions of the footage (weather, time of the year, etc.).
2
Quickly update a model when field experts identify detection pitfalls, such as false positives or false negatives.
3
Silo models to avoid software updates for each new model version.
4
Enable models, field experts, and data scientists to form a virtuous cycle of collaboration.
Solution

Datalake: a centralized datalake to index, search and store all the data and track sources and metadata.

Monitoring System: a model & data monitoring system to assess quality & performance.

Model Registry: a single point of truth to version and centralize all models.

Hybrid deployment: Store data and deploy models on their own infrastructure. Leverage the Picsellia GDPR infrastructure for model training.
