How to process WingtraOne images in Pix4Dmatic

Learn how to process WingtraOne images with Pix4Dmatic.

Before installing Pix4Dmatic read the minimum and recommended hardware requirements and ensure that your device fulfills the requirements.

Pix4Dmatic is faster and more reliable than Pix4Dmapper for corridors and large datasets of more than 5000 images. 

Use WingtraOne images that have been geotagged using WingtraHub version 1.0 with Pix4Dmatic. Images tagged with older WingtraHub versions do not include orientation and accuracy information in the EXIF and therefore will not be correctly processed in Pix4Dmatic.

Step 1. Create the project in Pix4Dmatic

Open Pix4Dmatic and drag and drop the images or select the folder from the disk in the highlighted area.


Specify the project name and the disk location where the project will be saved and click on Start.


Step 2. Image and output coordinate system

Pix4Dmatic reads the horizontal and vertical coordinate system from the EXIF of the images. The images should have embedded geolocation and orientation, as importing .csv files is not possible in Pix4Dmatic.

For example, for PPK geotagged WingtraOne images where the base location in WingtraHub was provided in WGS 84 system, the horizontal image coordinate system in Pix4Dmatic is automatically set to WGS84 - EPSG:4326 and the vertical coordinate system is automatically set to ellipsoidal height over the WGS84 ellipsoid.

The coordinate system of the outputs is defined based on the location of the project. If the image coordinate system is WGS 84, the corresponding UTM zone is used as the output coordinate system. 

The output coordinate system can be seen at the bottom of the window.

Step 3. (Optional) Import GCPs

When GCPs are used, the output coordinate system corresponds to the GCPs coordinate systems.

If the GCPs coordinate system is geodetic the corresponding UTM zone is used for the output coordinate system.

You can import the GCPs by clicking on the highlighted button.


Import a .txt or .csv with the GCPs coordinates following the format specifications of the Pix4D article and specify the coordinate system, horizontal and vertical, to which the GCPs refer. After the GCPs coordinates have been entered, you need to mark the GCPs.


Step 4. Image calibration

After creating the project and importing and marking the GCPs (optionally), the calibration of the images can start. RX1 images are of high resolution. To speed up processing select the 1/2 option for the image scale. Then click on Start to start with the calibration process.


Step 5. Assess the calibration results

Once the images' calibration is finished, take a look at the report in Pix4Dmatic and see the number of calibrated images and the average GSD of the project. In case GCPs are used, check the mean GCP RMS error to assess the accuracy of your project.


Step 6. Generate all the outputs for the project

Generate the point cloud, DSM and orthomosaic of the mapping area. Select the options Densify, DSM and Orthomosaic and click on Start


Once the processing is finished,  you can export the report in a .txt file format.
