Lab5 - why Segmented Image is always black? RRS feed

  • Question

  • I'm working on lab5 Using Vision to Estimate the Distance to an Object.

    I followed the steps and I ran the lab5 solution that's in courseware,

    they both gave total black image for Segmented Image result when I open the service through browser

    with this URL :


    The source image is fine though, just like a normal webcam source.

    Here are some other data on colorsegment page:

    Refresh Interval :250

    Frame Rate: Stopped

    droppped frames 8003000 %


    Threshold: 1.25, Despeckle unchecked, Minimum Blob size 0 and unchecked.


    and bunch of color definitions that there when I opened it.



    and if I open http://localhost:50000/lab5 page,

    the distance is always -1.



    Need help on this please.

All replies

  • and I just found something interesting.

    When I'm hold the webcam and pointing it to different objects,  the segment image window

    always shows a black image. And I accidentally flipped my mouse and the laser under the mouse

    was facing the webcam, and suddenly there are bunch of red dots showing up in the segment image window.


    However, in the meantime, the value of distance is still -1 when I open http://localhost:50000/lab5 page.

    (I'm holding the mouse and facing the laser to the webcam and using tab key to switch between webcam page and lab5 page)


    NEED HELP.....
