    Hi Bingan,

    You can find a description on what to adjust in the text-box in the design.

    Furthermore: If you downscale your subimage with the object you try to find, you may need to also downsample your input image so that the relationship between the object…

    Thank you for your advice
    I am trying to use my images, but the result shows failed (blank image)
    I loaded my .txt file into the FirOperator in the NCC hierarchical box. The text file is from the 12x12 Downscaled image I made by OpenCV.
    Could you please…

    Hi Bingan,

    Sorry for the confusion. The error message comes from the upcoming Opreator "SelectComponent". This in the example because an RGB Camera was used.

    Since you already have a gray camera you should be able to simply delete the "SelectComponent"…

    I think the problem is that I am using the gray camera operator, how should I modify the design? (change the RGB settings)

    Hi Bingnan,

    You can use the Operator "SplitComponents" to divide the input image in its three componets (R,G,B) and then compute the filter on each one. To combine the results together again to one RGB Image use the operator "MergeComponents"

    Greetings

    Hi I have downscaled the subimage into 12x12. A problem is that the link property. How should I change the parameter from RGB to gray?

    Dear Bingnan,

    Thank you for your question.

    When using FIR kernel one has to be careful not to use too large Kernels, since this will increase the used FPGA ressources by a lot. Therefore, it is important to know how large your sub-image will be?

    If it is…

    Hi ,

    I am tryin to do the template matching: I tested the provided example "normalized cross correlation". The example seems to detect the object with dimension of 12 pixels by using the operator FIR kernel 12x12, is this correct?

    Hello agorgolewski
    Thank you for your question and welcome to the forum. Your question is hardware and runtime related. I suggest to generate a Basler support request to get an answer to your question. In this forum mostly VisualApplets related…

    Hello,
    I have a problem with a camera connection via the Basler camera SDK. Time required to establish a connection seems to be completly random and sometimes takes a huge amount of time.

    Dear Bingnan,

    parallism gives information on how many pixels are transferred per clock cycle in parallel. With the parallelism you can control the bandwidth in your design. You may find further information in the VisualApplets documentation under

    Thank you, may I ask what are the rules to set the parallelism and width?
  • CarmenZ

    Post
    Dear Bingnan,

    thank you for the design. The error is due to the following: Parallelism is 8. The maximum image width of 1700 is not divisble by 8. An maximum image with for example of 1696 pixels or any width divisible by 8 is possible.

    I am trying to revise the example "PrintInspection" to convert to my platform mE5-VCX-QP. I replaced the dummy camera with the operator, but there appeared an error with the parameters:

    Dear Pier,

    Please use the newer MicroDisplayX tool of the most current runtime version.
    This version enables a more detailed synchronization:
    Within this new tool you can start cameras and DMAs independently.
    So you can start the camera streams first and…
