Algorithm overview

Description

AutoGCPs automatically locates Control Points (CPs) in images and detects their centers with pixel-level accuracy.

Pix4Dengine SDK and Automarking automatically exchange required inputs and outputs. Users can optionally configure the Automarking algorithm with the parameters available in automarking.Config. Automarking sends back to Pix4Dengine SDK information on the image marks, so that they can be automatically used to re-optimize or re-calibrate. Automarking also produces a report summarizing the Automarking run.

Supported use cases

Currently we support three kinds of targets: square, diagonal, and Aeropoint (see images below). Both nadir and oblique flights are supported. CP detection is currently supported only on RGB images.
