Accelerate GCP workflow with Tag Detection in PIX4Dcatch
In the dynamic world of photogrammetry and 3D mapping, efficiency and accuracy are paramount. Recognizing this, Pix4D has made a groundbreaking advancement with the introduction of the Tag Detection feature in PIX4Dcatch. Our goal was clear: to streamline the workflow with Ground Control Points (GCPs) and elevate the entire scanning process to new heights of precision and ease.
Traditionally, the use of GCPs, while essential to improve accuracy, came with its own set of challenges. Users, whether working with GNSS rover or without, expressed a strong need for a more integrated GCP experience. Previously, the integration of GCPs into your workflow involved a manual, somewhat cumbersome process. After capturing your scene, the next step was to painstakingly mark each GCP in the captured images – a task that could be both time-consuming and, at times, frustrating, especially when working on an iPhone.
What is Tag Detection?
Welcome Tag Detection – a feature meticulously designed to transform this scenario. With Tag Detection, the moment you capture your scene using PIX4Dcatch, a seamless and automated process kicks into gear. The feature intelligently identifies the GCP tags present on the ground and links them to the correct, pre-georeferenced GCPs in your point collection. This integration happens in real-time, during the capture phase itself. As you navigate through the site, you'll witness the magic of Augmented Reality (AR) as each tag is automatically recognized and matched with the corresponding GCP you’ve measured.
This innovative feature not only saves precious time but also significantly reduces the margin of error, predominantly originating from manual input. By automatically marking every visible tag across multiple images, the algorithm ensures precise accuracy in GCP representation. This is a great contrast to manual methods, where user fatigue often leads to fewer marks and potential inaccuracies. With Tag Detection, Pix4D proudly offers a solution that meets user needs and redefines the limits of photogrammetric mapping.
