Version 10.1.1

Features

Changes

  • Configuration file
    • Added option sos_correction to optics section. It enables size of source correction for devices that support it.
  • Overhaul of the startup/connection process. It features
    • an improved arbitration between detected and configured device connection details.
    • an automated reconfiguration of the IP address Ethernet devices send their frame data to.
    • an automated adjustment of the video format, if an Ethernet capable device uses a different connection interface as configured.
    • a rejection of devices that already have an active connection.
  • Radiation parameters
    • Added a class RadiationParameters encapsulating a set of emissivity, transmissivity and ambient temperature values. It also features a flag indicating whether the SDK should estimate the ambient temperature based on internal thermal probe readings. It used throughout the API.
    • Ambient temperature estimates are now updated when the readings of the internal probes from which it is derived changes.
    • Radiation parameters are only updated every 500 ms regardless whether their values are set by the PIF, the SDK or a SDK client.
    • The FrameMetadata object returned by the IRImagerClient::onThermalFrame() callback now contains the radiation parameters and their respective sources that were used to process the frame.
    • The MeasurementField objects returned by the IRImagerClient::onMeasurementField() provide these details for their respective fields.
  • Video formats
    • Clipped video formats (PI 640I and PI 1M) are now centered within their larger formats.
  • API
    • DeviceInfo
      • Added a busy status indicating whether the device already has an active connection.
      • Added MAC-Address information for devices on a network.
      • Added a connection interface address that returns the endpoint for USB connections or the IP address of the SDK client with Ethernet connections.
    • Enumeration Manager
      • Added methods to add and remove detectors for USB and Ethernet devices.
      • The EnumerationClient now features an additional callback onDeviceDetectionChanged() that is triggered when the details/status of a detected device changes (for example an available device accepted a connection).
    • FrameMetadata
      • Added getters for the radiation parameters and their respective sources used to process the thermal frame.
    • IRImager
      • Added setters for the active operation mode.
      • Added a setter and getter to en-/disable
        • size of source correction.
        • high precision temperature measurements.
        • temperature range extension.
      • Added getters for the device connection details (connection interface, device IP address and reception port).
      • Added getters returning the current source of radiation parameters.
      • Updated the setter and getter for the radiation parameters of the overall thermal frame.
    • IRImagerClient
      • Added callback onVideoFormatChanged() that is triggered upon a new device connection or when the video format changed due to a new active operation mode.
    • MeasurementField
      • Added getters for the radiation parameters and their respective sources used to process the field.
    • Sdk
      • Added a method to reconfigure the logger settings.
  • Command line tools
    • otc_configure_ethernet. Added command line options to find and configure devices on the network.
    • otc_find_devices. Added command line options to support Ethernet device detection and updated output.
  • Examples
    • All examples add a detector for Ethernet devices on the network 192.168.0.0/24 by default.
    • All Simple View examples can now cycle through the available operation modes and display hot and cold spots.
  • Various internal improvements to the core library and bindings for better performance and thread safety.

Bugs

  • Fixed static linking with MSVC on Windows.
  • Fixed debug builds with MSVC on Windows.

Version 10.1.0

Features

Changes

  • Configuration file
    • Added the following new sections to accommodate the new features
      • Fail safe
      • Measurement fields
      • Process Interface
    • Incremented file version to 2 but remains compatible with version 1.
  • Measurement fields
    • All measurement field related headers are now located in otcsdk/fields folder.
    • Measurement fields are now created with the help of MeasurementFieldConfig objects.
    • Measurement fields can now be assigned a mode that defines what data point is returned by the MeasurementField::getDataPoint() method.
  • API
    • The active operation mode can now be accessed via the getActiveOperationMode() method of the IRImager.
    • The ThermalFrame and MeasurementField classes now offer a copyTemperaturesTo() method that copies all their thermal data in degree Celsius to a target array.
  • Language bindings
    • The Python 3 bindings now offers access to the string conversion functions for the C++ enums in the SDK. Since C++ enums are converted to integer constants the names of these functions must be made more specific by adding a prefix. For example, use deviceTypeToString() for any DeviceType_<Value> constant to get the corresponding string representation.
  • Examples
    • All simple view examples now feature the ability to display the FPS and shutter flag state as well as the possibility to trigger a manual flag cycle.
    • Reduced the overall console output of the examples.
  • Windows
    • The default installation path changed to C:\Program Files\Optris\otcsdk. The installer automatically removes the old version and adjust all relevant environment variables and registry entries. An empty folder in the old SDK location may persist.
  • Linux
    • The OTC SDK Debian packages not longer conflicts with the ones of the IR Direct SDK.

Bugs

  • Fixed issues that prevented the SDK from correctly parsing and probing all available download sites for calibration data.
  • Fixed an issue that prevented the SDK from performing required automatic skim calibrations.
  • Fixed an issue that created pointless dependencies on other language bindings when using CMake to compile C++ SDK applications.
  • Fixed a memory access issue that caused the compilation with an active Address Sanitizer to fail.
  • Fixed an issue that caused memory access violations in multi-threaded environments with USB cameras while disconnecting.
  • Other minor bug fixes and improvements.

Version 10.0.1

Features

  • Extended and enhanced the documentation.
  • Improved Python 3 bindings downwards compatibility on Windows to Python 3.9 and NumPy 2.0.0.

Bugs

  • Fixed an issue that caused the installation of the Debian packages to fail on headless systems.
  • The method EnumerationManger::getDetectedDevices() will no longer block indefinitely, if its argument is set to 0.
  • The Simple View terminal windows will no longer close immediately upon an error.
