Introduction

hese release notes describe the new features and changes in the IDS NXT 3.0 release. This release updates the following components:

IDS lighthouse 3.0

You find the release notes for IDS lighthouse directly in IDS lighthouse: https://ids-lighthouse.ai/login/

IDS NXT OS 3.0

You find the release notes for IDS NXT OS 3.0.0 under Release Notes for IDS NXT OS 3.0.0

IDS NXT cockpit 3.0

This version of the IDS NXT cockpit supports Windows 10 64-bit (version 22H2) and for the first time Windows 11 64-bit (version 22H2).

New and changed functions

The user interface of the IDS NXT cockpit has been redesigned and restructured.
The revised device dashboard now contains information about active vision apps and displays the live image from the camera.
The IDS NXT cockpit stores the last opened view within a camera session when you switch from the camera configuration to the dashboard and back.
You can now upload or update multiple vision apps at the same time.
You can upload a user-defined image in the IDS NXT cockpit e.g. to use it in a vision app for tests. This user-defined image could previously only be set via a REST command.
The display of the live image in the IDS NXT cockpit can be subsequently enhanced using a special function ("Sharpening"). The function is enabled by default.
It is also possible to set the DNS (domain name server) via the IDS NXT cockpit. The DNS could previously only be set via a REST command.

General improvements

In the dialog for the firmware update, you can display or save a log containing details of the update.
Fixed a bug that prevented the direct entry of numerical values for manual exposure. Prerequisite is the use of an IDS NXT OS version > 1.3.0.
The behaviour of ROI (region of interest) in Crawler has been enhanced and adapted to the behaviour of ROI in the camera.
The displayed values in the ROI generator were incorrect. This has been fixed so that the values now match the ROI values of the camera.
Fixed a bug with the sliders that caused decimal values between 0 and 1 to be rounded by mistake.
Fixed a bug that prevented a new IP address from being saved correctly when the IP address was changed in the Finder.

Classifier 3.0.0

In the user interface of the vision app, the general term "heat map" was replaced by the more specific term "attention map". This change has also been implemented in the REST interface of the vision app, so that corresponding REST calls may need to be updated.
The identifiers of the configurables in the REST interface have been adjusted: a_cnns has been renamed to cnn, enable_heatmap to enable_attentionmap and x_errorthreshold to errorthreshold.
The logging of the vision app has been improved.

CNN Evaluator 2.5.1

To display status information, now an information element is used instead of a configurable. In addition, the messages of the status information became more detailed.
The logging of the vision app has been improved.

Object Detector 2.1.1

The logging of the vision app has been improved.
General improvements

IDS NXT Vision App Creator 3.0

From version 3.0 on, the operating system Windows 11 64-bit is supported for the first time.
The IDS NXT API has been updated to version 3.0.0 so that you can program vision apps for IDS NXT OS 3.0.0.
TensorFlow lite has been integrated into the IDS NXT SDK libraries. You no longer need to build TensorFlow lite specifically for the camera, you can do the calculations directly in the IDS NXT framework.

Known issues

IDS NXT cockpit	Upload backups	The maximum possible backup size is limited to the free RAM space of the camera at the time of upload.
IDS NXT cockpit	Number of maximum accesses limited to 3 per camera	A maximum of 3 users can access the same camera via IDS NXT cockpit at the same time. This also applies in the context of self-programmed applications.
IDS NXT cockpit	Vision app "Crawler" is no longer usable.	The separate vision app "Crawler" is no longer compatible with IDS NXT cockpit 2.3.0 or higher, as the Crawler application has been integrated into IDS NXT cockpit from version 2.3 on. If you are working with IDS NXT cockpit version 2.3.0 or higher, uninstall the vision app "Crawler" if it is still installed on the camera.
IDS NXT cockpit	Icon for Crawler is displayed 2x in IDS NXT cockpit.	If the vision app "Crawler" is still installed on the camera after an update to IDS NXT cockpit 2.3, the crawler icon is displayed twice in the IDS NXT cockpit. Uninstall the previous vision app "Crawler" on the camera.
IDS NXT cockpit	Mixed operation of IDS NXT cockpit and IDS peak	In the case of mixed operation with IDS peak, uninstalling IDS peak or IDS NXT cockpit may lead to complications when updating the GUF files. After uninstalling, reinstall the remaining software to fix the problem.
IDS NXT cockpit	Vision apps and previous ROI feature (IDS NXT OS < 1.3.0)	If vision apps are still using the previous ROI feature, the ROI may show an incorrect position when switching binning.
IDS NXT cockpit	Multi camera viewer and vision app selection	If you have already selected a vision app for a camera in the multi camera viewer and you subsequently install a new vision app on this camera or delete a vision app, the vision app selection in the multi camera viewer is reset. Set up the vision apps on the camera. Configure the multi camera viewer. Select the vision app in the multi camera viewer.
IDS NXT cockpit	Maximum frame rate in freerun mode	To achieve the maximum frame rate in freerun mode, no images should be displayed with the IDS NXT cockpit due to performance reasons.
Vision apps	Vision app crashed	If a vision app has crashed, you have the following options to restart it: Open the IDS NXT cockpit and restart the vision app in the VApp Manager. When the camera is restarted, the vision app is automatically restarted. If the problem persists, contact the vision app developer.
Object Detector	Result output	Japanese characters cannot be displayed in the result image.
Classifier	Result output	Japanese characters cannot be displayed in the result image.
Classifier	Nets with attention maps	It was noticed that in certain cases classification results differ significantly, which is likely due to the different net architectures. If you use nets with attention maps, you may get different results compared to nets without attention maps. These differences occur because different net architectures are used for training. For serial application, we recommend to use nets without attention maps.
OPC UA Server	New installation of a vision app	After reinstalling a vision app, it may be necessary to call the "PrepareRecipe" method twice to enable the corresponding recipe. Alternatively, after reinstalling a vision app, it is recommended to start it once initially.
IDS NXT Vision App Creator	Update of the IDS NXT Vision App Creator	After an update, the setting of the alternative "Source Folder" for projects must be reset.
IDS NXT Vision App Creator	Update the virtual machine	During the update, the virtual machine is deleted and replaced by a new one. Before updating, you must manually back up files that you have stored in the previous virtual machine and want to use further.
IDS NXT Vision App Creator	Uninstallation	The installation of the IDS NXT Vision App Creator does not require administrator privileges. If you installed the previous version as an administrator, the uninstall entry in the Control Panel may not be removed automatically. Go to "Control Panel" → "Programs and Features" and uninstall the previous version of IDS NXT Vision App Creator here.
