Member Data Documentation

acquisitionIdleTimeMax_ms

readonly PropertyI acquisitionIdleTimeMax_ms = new PropertyI()

inherited

An integer property defining the maximum time in ms the driver waits for new requests being queued until streaming by the device will automatically be stopped.

This property defines the maximum time in milliseconds the driver waits for new mv.impact.acquire.Request objects being queued by calling mv.impact.acquire.FunctionInterface.imageRequestSingle once the driver will automatically send an acquisition stop command to a streaming device (such as a GigE Vision device) when the driver's request queue has run empty (thus the driver has no more buffers to capture data into).

This property will only be taken into account when mv.impact.acquire.Device.acquisitionStartStopBehaviour has been set to mv.impact.acquire.TAcquisitionStartStopBehaviour.assbDefault.

Note

This property will not be available for every device. Right now only devices operated through the GenTL driver package will support this feature.

Since

2.4.1

acquisitionMode

readonly EnumPropertyI<TAcquisitionMode> acquisitionMode = new EnumPropertyI<TAcquisitionMode>()

inherited

An enumerated integer property defining the acquisition mode of the device.

Valid values for this property are defined by the enumeration mv.impact.acquire.TAcquisitionMode.

featurePollingEnable

readonly EnumPropertyI<TBoolean> featurePollingEnable = new EnumPropertyI<TBoolean>()

inherited

An enumerated integer property defining whether features defining a polling time shall be updated automatically or not.

Valid values for this property are defined by the enumeration mv.impact.acquire.TBoolean.

mv.impact.acquire.SystemSettings.featurePollingInterval_ms

featurePollingInterval_ms

readonly PropertyI featurePollingInterval_ms = new PropertyI()

inherited

An integer property defining the polling interval in ms the driver waits for each iteration before running through update loop again.

Some features define a so called polling time. This is a recommendation by the device/driver stating that this property might change it's value without user interaction act a certain rate (e.g. the device temperature could be one example for a feature with such a behaviour). When mv.impact.acquire.SystemSettings.featurePollingEnable is set to mv.impact.acquire.TBoolean.bTrue a thread will check every featurePollingInterval_ms if features need to be updated. This will only cause communication with a device for each feature who's polling time has elapsed.

Note

This property will not be available for every device. Right now only devices operated through the GenTL driver package will support this feature.

Since

2.18.3

footerCheckEnable

readonly PropertyIBoolean footerCheckEnable = new PropertyIBoolean()

An enumerated integer property allowing to switch on/off the check of the image footer.

The image footer contains certain additional data as e.g. the exposure time as used by the image sensor. To debug transfer related problems it sometimes can be useful to disable all internal data consistency checks by the driver.

Valid values for this property are defined by the enumeration mv.impact.acquire.TBoolean.

footerMode

readonly EnumPropertyI<TBlueFOXFooterMode> footerMode = new EnumPropertyI<TBlueFOXFooterMode>()

An enumerated integer property defining the footer mode of the device.

Valid values for this property are defined by the enumeration mv.impact.acquire.TBlueFOXFooterMode.

genDCParserEnable

readonly PropertyIBoolean genDCParserEnable = new PropertyIBoolean()

inherited

An enumerated integer property which can be used to enable/disable automatic GenICam™ GenDC Container parsing.

When working with a GenICam™ compliant device, that transmits data using the GenDC format this property can be used to switch on/off the automatic parsing of the received containers. The default value of this property will be mv.impact.acquire.TBoolean.bTrue, so a GenDC container will be parsed upon reception and will be reported as the individual components like described here Multi-Part Format. This results in slightly more CPU time being consumed which sometimes might not be desirable since the GenDC Containers shall be processed later by another entity of the application or shall just be written to some storage location for off-line processing at a later moment in time. When this property is set to mv.impact.acquire.TBoolean.bFalse the data buffer will reported as a raw GenDC Container. mv.impact.acquire.Request.payloadType will return mv.impact.acquire.TPayloadType.ptGenDC then and mv.impact.acquire.Request.imagePixelFormat will be mv.impact.acquire.TImageBufferPixelFormat.ibpfRaw then. mv.impact.acquire.Request.imageData and mv.impact.acquire.Request.imageSize however can directly be fed into any GenDC capable algorithm.

Note

This property will not be available for every device. Only GenICam™ compliant devices will support this feature. More Information about the GenICam™ GenDC format can be found here: https://www.emva.org/standards-technology/genicam/genicam-downloads/.

Valid values for this property are defined by the enumeration mv.impact.acquire.TBoolean.

3.2.0

imageProcessingMaximumThreadCount

readonly PropertyI imageProcessingMaximumThreadCount = new PropertyI()

inherited

An integer property influencing the number of parallel threads used by the internal image processing pipeline.

This property can be used to control the size of the internal thread pool used for image processing tasks. Using a value higher than the number of physical CPU cores usually has a negative impact on the performance. Use with care!

Note

This property will only be available on some platforms. Always check if this property is available before using it!

imageProcessingMode

readonly EnumPropertyI<TImageProcessingMode> imageProcessingMode = new EnumPropertyI<TImageProcessingMode>()

inherited

An enumerated integer property influencing the behaviour of the internal image processing pipeline.

Valid values for this property are defined by the enumeration mv.impact.acquire.TImageProcessingMode.

Note

This property will only be available if mv.impact.acquire.Device.userControlledImageProcessingEnable has been set to mv.impact.acquire.TBoolean.bTrue before the device is opened.

imageProcessingOptimization

readonly EnumPropertyI<TImageProcessingOptimization> imageProcessingOptimization = new EnumPropertyI<TImageProcessingOptimization>()

inherited

An enumerated integer property influencing the behaviour of the internal image processing algorithms.

Valid values for this property are defined by the enumeration mv.impact.acquire.TImageProcessingOptimization.

Since

2.12.2

methodPollingInterval_ms

readonly PropertyI methodPollingInterval_ms = new PropertyI()

inherited

An integer property defining the polling interval in ms the driver waits during each iteration before checking a methods execution state again.

When working with a GenICam compliant device, GenICam method objects need to be checked for their completion status every now and then. This parameter defines how often this shall be done.

Note

This property will not be available for every device. Right now only devices operated through the GenTL driver package will support this feature.

Since

2.18.3

methodPollingMaxRetryCount

readonly PropertyI methodPollingMaxRetryCount = new PropertyI()

inherited

An integer property defining the polling interval in ms the driver waits during each iteration before checking a methods execution state again.

When working with a GenICam compliant device, GenICam method objects need to be checked for their completion status every now and then. This parameter defines how often this shall be done at all. A method is checked for completion methodPollingMaxRetryCount * methodPollingInterval_ms at max. Until then either the device starts to inform the driver that it needs more time OR the execution of the method has completed successfully or an error will be generated.

Note

This property will not be available for every device. Right now only devices operated through the GenTL driver package will support this feature.

Since

2.18.3

powerMode

readonly EnumPropertyI<TDevicePowerMode> powerMode = new EnumPropertyI<TDevicePowerMode>()

An enumerated integer property defining the power mode of the device.

Note

This property requires at least firmware version 39! See mv.impact.acquire.Device.firmwareVersion to find out which firmware is currently running on the device or use mv.impact.acquire.Device.updateFirmware() to update the firmware to the state compiled into the driver.

Do NOT modify this property when images are acquired in parallel. Switching off or on the power for a device that is capturing images at the same time will result in incorrect images! Therefore always make sure to stop image acquisition and clean up BEFORE modifying this property.

Valid values for this property are defined by the enumeration mv.impact.acquire.TDevicePowerMode.

requestCount

readonly PropertyI requestCount = new PropertyI()

inherited

An integer property defining the number of requests allocated by the driver.

Each request object can be used to capture data into. Multiple requests can be processed by a device driver as background tasks.

Setting this property to a value at least allowing a driver to capture data for up to 500ms without user interaction (thus 0.5 times the expected frame rate) is highly recommended. Increasing this value will NOT introduce additional latency to your application. The only drawback will be additional RAM consumption by the driver but applications that do not need to copy the request buffers can even benefit from that as the overall memory fragmentation is likely to get less than. Values smaller than 3 most likely result in undesired behaviour and should be avoided unless absolutely needed.

Note

For performance reasons this value can be increased at any time(only exception: Working with the interface layout mv.impact.acquire.TDeviceInterfaceLayout.dilGenICam while streaming is active) but can only be decreased when no request object is currently locked by the application and no requests has been queued for acquisition. So modifying this value might require the application to call mv.impact.acquire.FunctionInterface::imageRequestReset and several calls to mv.impact.acquire.Request.unlock before.

There are not too many reasons to modify the default request count suggested by the device driver. Good reasons include:

• a single image is huge compared to the overall system memory(e.g. a single image has 200MB while the system itself only has about 2GB of RAM. Here it might make sense to reduce the number of capture buffers to 1 or 2. Please note that in such a scenario double buffering or live display when one buffer is constantly blocked by the display engine can become a challenge!
• the frame rate is high(larger than 100 frames per second) and no frames shall be lost. Here it might make sense to set the number of capture buffers to something like frame rate divided by 2 to 5 as a rule of thumb.
