v4.0.0

Here is a comprehensive list of the changes to the HAL API introduced in this release ordered by class:

• DeviceDiscovery
  • Added DeviceDiscovery::list_device_config_options function to get a list of (key,option) representing configuration options that can be set on a DeviceConfig to customize the way a device can be opened
• I_AntiFlickerModule
  • Changed enable()/disable() into bool enable(bool)
  • Removed set_frequency function from HAL I_AntiFlickerModule (function set_frequency_band should be used now)
  • Removed set_frequency_band boolean parameter stop and added set_filtering_mode to select AFK filter
  • Added some functions to get/set advanced AFK configuration (threshold, duty cycle etc.)
• I_CameraSynchronization
  • Added class allowing to control the camera mode (standalone, master or slave)
• I_Decoder
  • Decoding is now handled in I_EventsStreamDecoder and I_EventFrameDecoder
• I_DeviceControl
  • This class was removed
  • Functions start and stop are now handled via cpp:class:I_EventsStream Metavision::I_EventsStream class. An example of new API usage can be found in metavision_hal_showcase sample
  • Functions set_mode_standalone, set_mode_master, and set_mode_slave were moved to I_CameraSynchronization class. An example of new API usage can be found in metavision_hal_sync
  • Function reset was removed
• I_DigitalCrop
  • Added class to leverage digital cropping offered by last generation of sensors
• I_DigitalEventMask
  • Added class to enable/disable pixels individually
• I_ErcModule
  • Renamed I_Erc class into I_ErcModule
  • Changed void enable(bool) into bool enable(bool)
  • Added functions to retrieve some ERC settings (e.g. get_min_supported_cd_event_rate, get_max_supported_cd_event_rate)
• I_EventTrailFilterModule
  • Renamed I_NoiseFilterModule class into I_EventTrailFilterModule
  • Changed void enable(Type type, uint32_t threshold)`/disable() into bool enable(bool state)
  • Added set_threshold and set_type functions to configure the filter
  • Added functions to retrieve some filter settings (get_min_supported_threshold, get_max_supported_threshold)
• I_EventsStream
  • Replaced Future::I_EventsStream class with I_EventsStream, making the seek feature part of the default Metavision:: namespace
  • Changed methods seek and get_seek_range to non-virtual methods
• I_HW_Identification
  • Removed get_system_version
  • Removed as_string from HAL in favor of name_ field
  • Renamed get_available_raw_formats to get_available_data_encoding_formats
  • Added get_current_data_encoding_format function
  • Added field name_ to SensorInfo
• I_Monitoring
  • Added get_pixel_dead_time to retrieve pixel dead time (aka. “refractory period”)
• I_ROI
  • Removed I_ROI::set_ROIs which was creating multiple ROI windows using row/columns mechanism hence creating “shadow symmetric” windows. The new function I_ROI::set_windows allows to create proper ROI Windows but multiple windows are only available in some sensors. The old set_ROIs behaviour with “shadow symmetric” windows can now be achieved using I_ROI::set_lines.
  • Removed I_ROI::set_ROIs_from_bitword, use the I_ROI::set_lines instead
  • Removed I_ROI::set_ROIs_from_file
  • Renamed I_ROI::set_ROI to I_ROI::set_window
  • Added I_ROI::get_max_supported_windows_count function that returns the maximum number of independent windows supported by the device
  • Added I_ROI::set_windows function to set multiple independent windows: an exception will be thrown if the number of windows passed is higher than what is returned by I_ROI::get_max_supported_windows_count
  • Added I_ROI::set_mode function to switch between the ROI and RONI mode when supported
• I_TriggerIn
  • Added I_TriggerIn::get_available_channels function to get the list of channels that are available and can be enabled/disabled
  • Numerical values for the channel argument of I_TriggerIn functions replaced by a strongly typed enumerations that abstracts the actual channel value. I_TriggerIn::Channel::Main, I_TriggerIn::Channel::Aux and I_TriggerIn::Channel::Loopback should now be used instead of the actual numeric value specific to the underlying system.
• I_TriggerOut
  • Added I_TriggerOut::get_period and I_TriggerOut::get_duty_cycle functions

Other changes in OpenEB API:

• Base module
  • Added LogOptions class to be used with setLogOptions as a replacement for setLogLevel and setLogStream
  • Added LogOptions::setLevelPrefixPadding function to enable fixed length level block logging
• HAL
  • Renamed metavision_hal_viewer sample into metavision_hal_showcase to convey the info that this sample is meant to be used as an example of various HAL facilities rather than as a viewer.
• Prophesee Devices
  • Prophesee EVK1 devices plugins have been discontinued
  • Changed set method I_ll_biases implementation to raise exception when attempting to set an invalid bias

• Driver module
  • In AntiFlickerModule class, removed set_frequency (function set_frequency_band should be used now)
  • In Roi class, renamed Roi::Rectangle to Roi::Window
  • In Roi class, the function Roi::set(const std::vector& windows) will now try to set multiple independent windows and may throw an exception if the operation fails, as opposed to setting the union of rows and lines covered by the multiple windows as was done in previous releases
  • Renamed NoiseFilteringModule class into EventTrailFilterModule
  • Added Camera::from_serial overload that enables passing device config options
  • Renamed Camera::CameraConfiguration::event_format to Camera::CameraConfiguration::data_encoding_format
