PIE provides an intelligent inspection solution
using AI and deep learning.

It allows computers to classify, analyze, and learn mass data like the human brain.
Deep learning is one of the Machine Learning techniques for self-analysis and processing of data that allows computers to classify, analyze, and learn like the human brain.

It enables the infrastructure to detect the anomaly or defects in ultra-high-speed mass production facilities and products with high accuracy and rapid processing speed.
By combining deep learning technique, advanced machine vision technology, and know-how, PIE realizes the infrastructure to detect the anomaly or defects in ultra-high-speed mass production facilities and products with high accuracy and rapid processing speed.

PIE uses a self-developed AI engine instead of using foreign solutions.
The AI capability of PIE is applied to the EV battery manufacturing line for major auto providers both in Korea and overseas to support smart manufacturing.
PIE combines rule-based algorithms and deep learning for prompt line response.
