[master]

Added

Changed

Removed

[2.15.0] - 2020.12.02

Added

• CPP: Add support for point cloud streams using extensions

• [Introduced in firmware v1.16] API: Add custom trigger API, which allows to control external trigger outputs for special product variants

• [Introduced in firmware v1.16] API: Add named scan pattern API. Multiple patterns can be persisted and are pre-loaded.

[2.14.2] - 2020.11.25

Changed

• Python: Raise minimum required Protobuf version due to incompability with currently specified version

[2.14.1] - 2020.11.09

Changed

• Python: Moved status stream to stream folder.

• Python: Unified stop and close in the different streams. Please now use stop in all the streams.

• [Introduced in firmware v1.15] Replaced linear filter with non-linear function. Please re-adjust filter configurations in scan patterns stored on the device.

[2.14.0] - 2020.10.19

Added

• [Introduced in firmware v1.14] API request to fetch constraints for allowed scan pattern configurations. This improves the Web GUI and results in improved validation error messages.

Changed

• Python: Fixed point cloud stream close to first call stop and unsubscribe

• Python: Fixed bug when stopping a raw stream and deleting it afterwards, it would call stop again

[2.13.0] - 2020.09.25

Added

• [Introduced in firmware v1.13] Separate API request for raw file streams. This allows file recordings with Python on low-performance clients.

• [Introduced in firmware v1.13] Server section to status message. Reports connected clients and network statistics.

• Add protocol files to install target

• [Introduced in firmware v1.13] Extend advanced configuration with default_point_cloud_subscription

• [Introduced in firmware v1.13] Request to attempt error recovery

Changed

• Python: Improved examples and refactored arguments

• CPP: Refactored point cloud recording class

• CMake: Improved the approach of linking dependent library to make the install package relocatable

Removed

• [Removed in firmware v1.13] Drop deprecated legacy scan patterns

[2.12.1] - 2020.09.08

Changed

• Windows: Only disable Protobuf-related warnings

• Python: Throw explicit error types in point cloud stream class

[2.12.0] - 2020.09.08

Added

• Protocol: Additional processing section in advanced configuration

• Example for builds with external projects which locates all dependencies in a local directory. Can be found in cmake/external. Install section in documentation is updated.

Changed

• Bugfix: M_PI was not defined and compiler flags were overridden in cpp windows builds

[2.11.1] - 2020.08.31

Added

• Python: Flag for detecting frame losses

Changed

• Change default scan pattern to 40 scanlines up, 40 scanlines down, INTERLEAVE pulse type, and COMBINE_UP_DOWN pulse frame mode

• Protocol: Formatted protobuf files for better readability

• Python: Follow PEP 8 version rules

[2.11.0] - 2020.08.17

Added

• Python: Example of frame export for matlab / octave

• [Introduced in firmware v1.10] Add filter parameters to scan pattern. It allows to increase the number of returns per point and provides min/max filters for point attributes. The filter can be overridden during a stream request.

• [Introduced in firmware v1.11] Add preliminary noise filter configuration to scan pattern

• Protobuf: Add internal message option to trigger export of custom targets

• CI: Provide test coverage

• [Introduced in firmware v1.11] Interleave frame mode, which allows to double the horizontal density with the COMBINE_UP_DOWN FrameMode and efficiently uses the down-ramp phase in the inner horizontal FoV

• [Introduced in firmware v1.11] Add API request for advanced configuration

Changed

• Bugfix: Removed incorrect end of line prints in cpp fetch_clouds example

[2.10.2] - 2020.07.22

  • Validates the hardware, operates the device, and generates a report.

  • The report is currently only accessible by developers.

  • A success flag indicates if the device is functional.

• [Introduced in firmware v1.9] Configurable point-cloud stream: Used to reduce the network bandwidth and to decrease the Protobuf encoding/decoding effort

  • The post-processing can be configured with a filter. It allows to increase the number of returns per point and provides min/max filters for point attributes.

  • The desired frame fields in the stream can be requested by passing a reference frame. Example reference frames are available.

• The field of view in ScanPattern.Horizontal now defines the optical FOV, not the mechanical FOV as previously. The padding configuration in ScanPattern.Pulse is, therefore, obsolete. Additional, all scan patterns for Cube Range devices now require the optical ScanPattern.Horizontal.fov and ScanPattern.Pulse.angle_spacing. It is recommended to use Request.FillScanPattern with an empty configuration to retrieve a valid example configuration of the used device.
