2. Project data

Description

When the user uses the app to measure points in the real world, he/she will create a project containing information necessary to perform the calculations, such as camera parameters, the detected markers in the photos, and the calculated points.

Purpose

When a project is made, the user can close the app and continue or purchase the measurement another time. This data is also necessary for the server to calculate the points in the real world.

3. Photos taken with the app

Description

The photos taken with the app will be stored on the device on a location that only the app has access to. It will be stored with their original resolution and a resized thumbnail.

Purpose

The reason the photos are stored is mainly for user feedback. By looking at the photo, the user can see which markers were detected and which were not.

What data is collected using MarkerScan

When you use the MarkerScan app, the following data may be send to the server for the purposes of calculating points in the real world and sending the result to the user.

1. Project data

Description

When the user uses the app to measure points in the real world, he/she will create a project containing information necessary to perform the calculations, such as camera parameters, the detected markers in the photos, and the calculated points. It also contains some user information such as contact name and email address.

Purpose

The information is necessary for calculating the points in the real world and sending the result to the user. It is stored on the server in case the user lost his data and wants to recover it. This can be aqcuired by contacting Science [&] Technology Vision B.V.
