Scorpion Vision software supports SVS-VISTEK ECO family GigE cameras:

• SvsVistek.dll

Prerequisites

• Scorpion Vision Software version 8.0.0.441 or higher
• SVCam GigE SDK installed
• Cameras are configured and detected by SVCapture

Note: There are some issues with SVS when setting trigger signal to strobe. Our tests reveal that to start using Strobe signals, StrobePosition must be changed from positive to negative and back to the initial (or vice versa). It depends on TriggerPolarity - both parameters must be either positive or negative.
Python set/getProperty can be used to perform that inside Scorpion profile.

General

The following properties are available:

• AOI
• Width
  This value sets the width of the area of interest in pixels.
• Height
  This value sets the height of the area of interest in pixels.
• Binning
  The camera can be set to one of the following binning modes:
  • 0 - Off.
  • 1 - Horizontal.
  • 2 - Vertical.
  • 3 - 2x2.
• OffsetX
  This value sets the X offset (left offset) for the area of interest in pixels, i.e., the distance in pixels between the left side of the sensor and the left side of the image area.
• OffsetY
  This value sets the Y offset (top offset) for the area of interest, i.e., the distance in pixels between the top of the sensor and the top of the image area.
• Image
• PixelDepth
  The number of bits for a pixel (implemented 8bit).
• bayerMethod
  The image will be converted by a selectable Bayer conversion algorithm into a RGB image. Supports only color cameras.
  • -1 - None.
  • 1 - Simple.
  • 3 - HQLinear.
• UseLowPassFilter3x3
  A filter which smoothes an image inside a camera accordingly to a given algorithm 3x3. Supports only monochrome cameras.
• UseLUT
  This feature activates LUT (look-up table).
• LUT
  Apply lookup table. Lookup table must follow some rules, see an example.
• LUTtableRow
  Select a column name, provided by LUTtable text file.
• Gamma
  This feature is used to perform gamma correction of pixel intensity (active when UseLUT is disabled).
• Analog
• FrameRate
  Configure the frame rate manually. However, you cannot increase the frame rate beyond the fastest settings. In addition, if the exposure time is longer than the configured frame period, the frame rate will be reduced in proportion to the exposure time. When you want to minimize network traffic, use this setting to lower the frame rate while maintaining the same shutter setting.
• ExposureTime
  This feature used to set the Exposure time (in us).
• ExposureDelay
  The camera's exposure delay in micro seconds relative to the trigger pulse will be set to the provided value. The delay will become active each time an active edge of an internal or external trigger pulse arrives.
• Gain
  This feature used to set analog gain (in db).
• GainOffset
  The offset value for pixel will be set to the provided value (0..255).
• Auto
• UseAutoGain
  This feature activates automatic gain control.
• AutoGainBrightness
  The target brightness (0..255) will be set which the camera tries to reach automatically when auto gain/exposure is enabled. The range 0..255 always applies independently from pixel depth.
• AutoGainLimitMin
  The minimal gain will be determined that the camera must not exceed in auto gain mode.
• AutoGainLimitMax
  The maximal gain will be determined that the camera must not exceed in auto gain mode.
• AutoExposureLimitMin
  The minimal gain will be determined that the camera must not exceed in auto exposure mode.
• AutoExposureLimitMax
  The maximal gain will be determined that the camera must not exceed in auto exposure mode.
• Acquisition
• AcquisitionMode
  The camera's acquisition mode will be set to the selected value:
  • 1 - Fixed frequency.
  • 2 - Software trigger.
  • 3 - External trigger / Internal exposure.
  • 4 - External trigger / External exposure.
• TriggerInput
  The camera's trigger line input will be set to the selected value:
  • 1 - None
  • 2 - IN1.
  • 4 - IN2.
  • 8 - IN3(RS422).
  • 16 - RXD(RS232).
  • 64 - Strobe.
• Output1
  The camera's trigger line input will be set to the selected value:
  • 1 - None.
  • 2 - IN1.
  • 4 - IN2.
  • 8 - IN3(RS422).
  • 16 - RXD(RS232).
  • 64 - Strobe.
  • 128 - FixedLow.
  • 256 - FixedHigh.
• Output2
  The camera's trigger line input will be set to the selected value:
  • 1 - None.
  • 2 - IN1.
  • 4 - IN2.
  • 8 - IN3(RS422).
  • 16 - RXD(RS232).
  • 64 - Strobe.
  • 128 - FixedLow.
  • 256 - FixedHigh.
• Output3(RS422)
  The camera's trigger line input will be set to the selected value:
  • 1 - None.
  • 2 - IN1.
  • 4 - IN2.
  • 8 - IN3(RS422).
  • 16 - RXD(RS232).
  • 64 - Strobe.
  • 128 - FixedLow
  • 256 - FixedHigh
• TXD(RS232)
  The camera's trigger line input will be set to the selected value:
  • 1 - None.
  • 2 - IN1.
  • 4 - IN2.
  • 8 - IN3(RS422).
  • 16 - RXD(RS232).
  • 64 - Strobe.
  • 128 - FixedLow.
  • 256 - FixedHigh.
• TriggerPolarity
  A camera can be set to positive or negative trigger polarity:
  • 0 - Positive.
  • 1 - Negative.
• StrobePolarity
  A camera can be set to positive or negative strobe polarity:
  • 0 - Positive.
  • 1 - Negative.
• StrobePosition
  The camera's strobe position in micro seconds relative to the trigger pulse.
• StrobeDuration
  The camera's strobe duration in micro seconds.
• Logging
• LogLevel
  
  • Level 0 suppresses all messages.
  • Level 1 issues error and warning messages.
  • Levels 2,3,4 issue diagnostic messages.
  • Beware that level 4 produces a lot of messages therefore should be used only on small size images for diagnostic purposes only.
• LogIntoFile
  Write camera related messages into log file. Normally messages are written only on Scorpion console, provided console is enabled for camera messages.
  Note: Setting is not stored in configuration and will be turned off on restart.

• 'exposuretime'
• 'exposuredelay'
• 'gain'
• 'gainOffset'

All properties can be dynamically accessed with 'getProperty' command.

Example 1: Start Continuous grabbing

  GetCamera('0').setProperty('continuous', 1)

Example 2: Stop Continuous grabbing

  GetCamera('0').setProperty('continuous', 0)

Example 3: set/get camera property

  GetCamera('0').setProperty('framerate', 30)
  print GetCamera('0').getProperty('frameRate')
