Course Project: AT319 Lab 08 Pix4DMapping with GCPs

I. Intro and Preparation

Date: 03/08/2023

We used Pix4D Mapping to create a large picture of Prof. Hupy’s home with GCPs. 

Refer to Lab 04 section one in AT309 to import the images, change the shutters, and the output coordinate systems. 

After the images were loaded, go to Project, and then GCP/MTP Manager to import the GCP data file. Change the default coordinate system to the projected coordinate system that the GCP used. Blue crosses will appear on the screen.

Figure 2: GCPs were added as the blue crosses

II. Initial Processing and Correcting

Uncheck 2 and 3 → Start. After Initial processing is finished, check if the image quality is good or not. 

Figure 3: initial processing done

Click each GCP on the left hand side, calibrate each GCPs on four of the images that contain the GCP manually.
