    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?

    Cam1.genicam.parameters.txt

    Cam2.genicam.parameters.txt

    Cam3.genicam.parameters.txt

    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,

    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,

    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.

    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


    Thanks,

    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,

    Hi All,


    I have generated an applet for VQ4-GE framegrabber with three cameras and I need to combine the binarized results of images from those cameras in order to output signal from PC.


    Image Dimension: 28 x 1


    Final appended result Dimension : 28 x 4


    where first ,second and third line represents the corresponding results from cameras. The Fourth line should be the combined result of all three cameras such as if a 1 is present in any of the first three lines , then the corresponding pixel in the last row should have 1.


    I have used Colmax operator for this purpose but it replaces the pixel values in between the lines also with the max value. Please refer the attached simulation applet and suggest me a working design!

    Dear All,


    I am using VQ4-GE framegrabber for my image processing application with GV-5260 CP color camera. Now I have a problem with setting genicam parameters through C# SDK(Runtime v5.6.0). First I changed the 'Exposure time' in genicam settings using the c# application, it has changed and updated in genicam explorer. Then I tried to set the Gain values in analog control but I can't able to set it even though it showed as set in application still it doesn't change the value in genicam.

    Code
    1. result = SiSoCsRt.Gbe_setEnumerationValue(managerUsed.GBECamHandle[index], name, value);

    This is the particular code I used to set it.

    Please help with example application code to set enumeration values like these in genicam explorer!


    Thanks,

    Jayasuriya.
