Getting Started

Prerequisites

IDS NXT Vision App Creator

To customize and build the vision app samples, we provide the IDS NXT Vision App Creator. The IDS NXT Vision App Creator is an IDE, based on Qt Creator for programming vision apps for IDS NXT cameras. The IDE includes the toolchain and the IDS NXT SDK. You can directly upload the vision apps from the development environment to your IDS NXT camera.

Documentation

IDS NXT API

The IDS NXT framework includes the IDS NXT API which offers a wide range of functionality to implement a variety of applications building your own vision app.

Examples

• Basic vision app example
• Using an ROI & result highlighting
• AI based classification
• AI based detection
• Face detection with OpenCV
• Handling multiple ROIs
• Processing multiple CNNs
• Using FTP & vision app website

How-To

Compiling a third party library

• OpenCV

Specifying metadata

You can specify the metadata of a vision app and metadata of the GUI element in the following files:

• Specifying vision app metadata (e.g. name, version, manufacturer, etc.) => manifest.json
• Specifying GUI element metadata (e.g. button names, descriptions, etc.) => translation.json

Licenses

See the license.txt file of the respective vision app for more information.
