  • Coprocessor Feature

    Hi Sir,


    I have gone through with the example applets provided in Visual applets installation directory and found an example in the path "C:\Program Files\SiliconSoftware\VisualApplets_3.2\Examples\Processing\CoProcessor\CoprocessorMedian" and the particular operator 'DMA From PC' has used in it. I Like to use the same feature in Marathon VCL framegrabber and noticed that the mentioned operator is only available for either VD1/VD4 framegrabbers. I wonder why it is not available for latest framegrabbers. Is there any alternative available? Can you please reply on this?

  • Delaying Images from Linescan camera

    Hi All,


    I am using Marathon VCL frame grabber with Silicon software run time v5.6.1 installed on PC and a 4K color Linescan camera with 13k line rate. I made a sample applet in which two signals are generated in SISO one for image trigger and the other acting like an encoder signal to grab the images. Here I need to delay or hold certain number of images in buffer then send to PC for synchronization purpose. For that a set of delay operators are used in sequence to delay images without loss. But whenever I set a delay value even with a single frame of delay , the buffer gets overflowed and this scenario is mostly encountered in Marathon frame grabbers because the same logic had been implemented on both VD4 & VQ4 cards but it worked there. Can anyone help with this problem? Please refer the attached applet below:

  • Image Acquisition on multiple cameras - LinescanHighspeed mode

    Dear Sir,


    I am using GV 5240 CP -M model camera for my project with firmware v 1.7.2837 flashed on it. So basically i'm using the 'LineScanHighSpeedmode' feature of this camera triggered @61 FPS from an OPTO trigger card IV. Three cameras of the same type are installed on microEnable IV series VQ4 framegrabber through GIGe interface with the runtime version v5.6.0. And the three cameras are triggered individually from Siso generated signals by the applet.

    Now I want to run all the three cameras together using the signals generated from applet but acquisition is not happening. So I modified the applet by putting each camera in to a seperate 'Process' namely Camera1 and its trigger generating module in a process1, Camera2 and its trigger generating module in a process2, and Camera3 and its trigger generating module in a process3 respectively. At this point all the three cameras are grabbing images of size 1280x1024 in triggered mode.

    But I need all the cameras to be in a same process so that I can append the images from the cameras for further processing .

    I have attached the sample applets and Genicam properties of the cameras for reference. Could anyone give a solution for this?

  • Micro display crash problem

    Dear BJorn Rudde,


    Thanks for the help , by the way I tried the new runtime version but the problem occurred sometimes only. So I thought the issue is with the PC itself then I reinstalled windows 7 os in my PC and now it is working well no more crashing problem so far.


    Thanks,

  • Micro display crash problem

    Dear All,


    I am using three no's of GV-5260 CP color camera in VQ4-GE framegrabber installed with SISO runtime v5.6.0 for my applet and the cameras are triggered seperately by framegrabber at 500 FPS. Now I am facing an issue where if any one of cameras are either powered off or trigger is not receiving then both the microdisplay and genicam explorer exits(crashing) without any warning. Here I have attached my sample image acquisition applet for your reference. Please suggest me a solution.


    ImageAcquisition_CameraFailCase_v1.0.va


    Note:- I ran the sample "QuadAreaBayer24" hap file provided in siso directory , there if I remove any particular camera (testing purpose) from the frame grabber the microdisplay is not crashing instead the corresponding DMA turns out to be in red color and acquisition stops.


    Thanks,

  • Shrinking an image vertically

    Hi All,


    I am using GV-5260 CP area scan camera connected with VQ4-GE framegrabber installed with SISO Runtime v5.6.0. I need to scale down an image ( shrink the image) vertically along y-axis. Can I get any example applet for doing so?!. I have attached a sample acquisition applet with source image for your reference.

  • How to get gray image from a RGB image

    Dear All,


    I am working with GV-5260 CP color camera using VQ4-GE framegrabber for my application. I need to get gray image out of RGB image captured from the camera. I am using the following formula for extracting gray image:


    Quote

    The three channels of the RGB image are passed as the first three channels of the input image. The image is transformed according to the following formula:


    gray = 0.299 * red + 0.587 * green + 0.114 * blue .

    Since there is no fractional input for any operators in Visual applets ( ver 3.1) , I have just multiplied the channels with 299,587 and 114 respectively and divided it by 1000. Is it the right way to do that or any other solution?

    Please refer my applet that I have attached here! ExtractIntensityChannel.va

  • GenIcam parameter settings issue

    Hai,

    I have already implemented the code in an c# application and I am aware of the syntax. But I was not able to set value using this function "Gbe_setEnumerationValue". So it would be better if you provide us with an working example c# application for setting and getting values in genicam through your SISO SDK.

    FYI, We have already sent a mail to your support but no response until now.


    Thanks,
