About This Product

Pix4D Auto-GCPs is an automated ground control point detection feature designed to simplify the georeferencing workflow in drone mapping projects. It identifies supported ground targets in aerial images and automatically marks their positions during processing, reducing the need for manual GCP marking. The feature is available in PIX4Dcloud Pro and can be used to detect both Ground Control Points (GCPs) and Check Points for improving and evaluating project georeferencing.

Key Features

• Automatic detection of Ground Control Points
• Automatic detection of Check Points
• Pixel-level target center detection
• Reduces manual GCP marking
• Integrated into the PIX4Dcloud processing workflow
• Supports square and diagonal targets
• Supports AeroPoint targets
• Works with RGB imagery
• GCP layer available for visual review
• Supports accuracy assessment through Check Points
• Suitable for drone mapping and surveying workflows
