Blickfeld-qb2

Highlights

* Added Point Cloud Recording Button in WebGUI Viewer, enabling one-click recordings which can be directly visualized and processed with open source tools such as [ParaView](https://www.paraview.org), [CloudCompare](https://www.danielgm.net/cc/), or [Open3D](http://www.open3d.org/).
* New features for Embedded Percept:
* Embedded Percept now supports cone-shaped volumes zones for simplified setup in non-rectangular material sites.
* New zone type, "exclusion," for excluding specific regions from data processing.
* Percept algorithms can now be tuned with a configuration panel in the WebGUI viewer.
* The [maximum frame rate](https://docs.blickfeld.com/qb2/Qb2/v1.10/protocol/blickfeld/system/config/scan_pattern.html#_blickfeld_system_config_ScanPattern_FrameRate) is now calculated for scan patterns and displayed in the WebGUI.
* Added [aggregation health service API](https://docs.blickfeld.com/qb2/Qb2/v1.10/protocol/blickfeld/diagnostics/services/health.html) to the blickfeld-diagnostics module, simplifying the monitoring of large sensor setups.

* Bugfix for Blickfeld Flow: Method & FQDN of blickfeld-qb2-method were overridden even though they had non-default values. Multiple nodes in a series always executed the gRPC method of the first node.
* Bugfix for core processing client health: IP address was not properly forwarded for non-WebGUI clients

Highlights

* An optimized point cloud stream with a voxel filter has been incorporated to enhance performance and data quality.
* Visualization for the volume map has been added in the WebGUI, along with a corresponding [API service](https://docs.blickfeld.com/qb2/Qb2/v1.9/protocol/blickfeld/percept_processing/services/volume_map.html).
* The [Time Synchronization API](https://docs.blickfeld.com/qb2/Qb2/v1.9/protocol/blickfeld/system/services/time_synchronization.html) service has been introduced, allowing custom NTP servers to be used and providing health information for improved time management.
* A significant performance boost has been achieved for the percept pipeline, resulting in a smoother and faster experience.
* Bugfix: A bug causing some devices to become unresponsive with the error message "Point Cloud stream not active" has been resolved.
* The point cloud in the viewer WebGUI color can now be colored by height, enhancing data analysis capabilities.
* Multiple improvements and bug fixes have been implemented in the WebGUI to enhance the user experience.

⚠ Breaking Changes

* The Percept StateList API has been refactored to the States API. Please ensure that the API clients are reviewed and updated accordingly.
* The MQTT output format has been updated due to the refactored Percept States API. It is required that the push configuration is revisited to align with the new format.

Highlights

* Blickfeld Flow (BETA): Low-code prototyping and integration tool for customizing and extending the functionality of a Qb2 sensor. [Read more](https://docs.blickfeld.com/qb2/Qb2/v1.8/foundations/flow.html)
* Improve start / stop logic: Qb2 will automatically stop when no point cloud clients are connected (after a 60s idle time)
* Bugfix: Sensor setup view broke when one of the configured sensors had a wrong IP or was offline
* WebGUI: Introduce a more linear point cloud coloring
* API: Add point-rate-too-low and misalignment-detection [flags](https://docs.blickfeld.com/qb2/Qb2/v1.8/protocol/blickfeld/core_processing/data/health.html#_blickfeld_core_processing_data_Health_ErrorFlags) to core processing health service
* Qb2 now also reports continuous timestamps in sensor setups without NTP server (previously timestamps were reset with every reboot)

* Bugfix: False positive security zone alarms

Highlights

* Blickfeld Services Connect: Simple integration with the Blickfeld Volume Monitoring solution and used for remote field support.
* Point Cloud Get / Snapshot: Instead of a stream, a simple get method is now available to fetch the latest point cloud frame.
* Normalize intensity / photon count: Compensates the intensity for range and thus produces more homogeneous data.
* Close Range Noise Improvements: In certain scenarios noise appeared in the close range. This should be reduced now.
* Bugfix: Scan Patterns are constrained correctly. A certain number of up & down scanlines is enforced for a certain vertical field of view.
* Improved stability of laser voltage controller: Has potentially been leading to a temporary device failure after several hours of operation
* Bugfix: Improve error handling in WebGUI
* CVE Security Patches
