    Protee : How to setup machine vision cameras

    This post will explain how to install and setup the machine vision cameras for LA and H-cam. This will be a work in progress and I will add to this post when I find time. They are also working on a new ball detection method so the procedure will change slightly.

    This link explains how to install the PTgrey camera drivers.
    csc.protee-united.com/entries/21114743-I...ision-camera-drivers

    Installing the drivers basically consist of installing the Flycapture 2.2. You can download it from Ptgrey.com or it can be found on the Protee install directory.

    USBview utility:
    Each camera will require an active USB 2.0 extension(16ft max) plus a USB to mini cable(12ft max). I would not go any longer than the two combined. Each camera should be connected to USB ports that are on separate controllers. You can use USBview
    www.ftdichip.com/Support/Utilities.htmto view the USB controllers and USB devices.

    H-CAM mounts:
    http://golfsimulatorforum.com/forum/...-housing-ideas


    LENSES:
    http://golfsimulatorforum.com/forum/...-camera-lenses

    Changing out the ProTee lens:
    First, see if you can just unscrew the old lens out. If you can't(don't force it), you'll have to remove the tiny set screw. Easiest way is to remove the camera shell first by removing the 4 screws at the corners. Then remove the set screw from the lens holder. Install the camera shell back on and screw in the new lens, hand tighten. Don't put the set screw back in. Just keep in a safe place in case you need it in the future. Adjust the two knobs for focus and you're done.


    Lights:
    You can use the ProTee lights or do it yourself. Here's a DIY lights thread:

    http://golfsimulatorforum.com/forum/...-lights-system

    The sensor mat light should use a 60-75w halogen spot bulb, while the 2nd light should be 60-75w flood(40-45* beam). The wattage depends on the mounted height of the lights.

    The sensor mat light should be mounted directly above the tee location, and not the center of the sensor mat. The 2nd light should be mounted directly above the putting sensor. The beam from the second light should overlap the sensor mat beam just a little, but not too much. Trust me on this one. See my H-cam picture.


    Mounting the Vcam:
    The V-cam can be mounted left or right, 6-7 ft from the sim room's center line and about 1 ft ahead of the sensor mat. It does not have to be exact(PT5). What's important is that it needs to be as low to the floor as possible and pointing slightly up, maybe 5-10*, and pointing perpendicular to the center line. Put a ball on a tee. Adjust the camera's position so that the ball is sitting on top of the red box in the camera. Use the horizontal line to align the camera. You want the horizontal line to be parallel with the floor or sensor mat.

    Note: If mounting the V-cam on the left, set the image to flip, save and exit out completely and restart the interface for the changes to take affect.

    Mounting the H-cam:

    H-cam is mounted on the target line between the putting sensor and the main sensor. Exact distance will depend on the mounting height. Set the H-cam method to PT1 and resolution to 640X480 if using my lens, then use the view in the camera to find the mounting location. Ball must be in the red square.

    PT camera methods:

    # Investigation methods Vertical Camera:
    # PT1= Find first point from the right bottom corner, investigating vertical lines (default)
    # PT2= Find first point from the left top corner, investigating horizontal lines
    # PT3= Investigate at an angle of ~45 degrees, perpendicular on this line
    # PT4= Analyse picture by finding the longest line, use tee-box and one point on this line
    # PT5= Analyse picture by finding the longest line, without using the tee-box (preferred)

    # Investigation methods Horizontal Camera:
    # PT1= Find first point from the right bottom corner, investigating vertical lines
    # PT4= Analyse picture by finding the longest line, use tee-box and one point on this line (default)
    # PT5= Analyse picture by finding the longest line, without using the tee-box (preferred)

    When setting up the cameras for the first time, it best to set all PT methods to PT1's. Then use my recommended settings below. Please see the recommended interfacesettings section on how to change settings. http://golfsimulatorforum.com/forum/...rface-settings

    Investigate_V_cam_method_wedges=PT5
    Investigate_V_cam_method_non_wedges=PT5
    Investigate_H_cam_method=PT1
    Investigate_V_cam_method_driver=PT5
    Investigate_H_cam_method_driver=PT1

    Vertical Cam Setup: csc.protee-united.com/entries/22330292-V...-Launch-Camera-Setup

    Changing camera resolutions:
    To change the resolution using the camera stream, set "Left" to 56. "Top" to 0.

    "Width" to 640. "Height" to 480. Apply, OK.

    Then click on "Preview" and make sure the resolution changed.

    If you can match mine, image wise and settings wise, it should work pretty good.

    H-cam setup is very similar to the Vcam setup above.

    1) In the H-cam setup window, select the ball path camera(via serial #) from the drop down list.

    2) Set the H-cam's resolution to 640X480. See instructions above.

    3) Set all settings to match mine in the above picture for both screens. In the "camera device" window(little box on the left in the picture above), shutter speed is 14 and frame rate is 40 fps. Set everything else to zero, including gain. Make sure to uncheck "auto" for everything. When making changes to the frame rate or resolution, you must click "preview" for the changes to take affect.

    4) Once all settings are set, mount the H-cam as high as you can and just forward of the sensor mat. It should be pointing straight down perpendicular to the floor. Put the tee location in the center of the red box. Use the vertical and horizontal lines to align the camera. Perfect alignment = accurate measurements.

    My settings will get you going. Depending on your floor's reflective property and lighting conditions, you might have to make a few adjustments. If you adjust the shutter and/or gain to match the look of what I have above, you should be good. Test some swings with Driver, wood, iron, and wedge. Must select the club for each type of test. If the software is detecting the club instead of the ball streak, adjust the minimum greyscale for that type of club until the software can detect the ball streak without failure.

    You must also click "save" as you exit the setup screens for the changes to be saved.

    Hi,

    I have a quick question, why in my vcam setup screen i see 640 X 480 at 60fps above the preview screen and when i use FlyCap2 and look at my cameras settigns, i see 40 fps ? When the vcam pickup my golf club instead of my ball, are they some parameters i must look at ?

      Go in to the camera device tab, auto should be unchecked for all parameters. Set FPS(frame rate) to 40, apply, OK. Then click on preview.

      If that works, close the vcam camera screen, save, close, then save again.

      Let me know if that works for you.

        No, it doesn't work, i will ask for a remote session with Protee because my setup is not working, when we place the ball on the tee, Protee think i hit a shot and i have to use a mulligan. (it happens 10-20 times in a round).

          That should not happen. Protee will fix it for you. Keep me posted.

            What is your audio sensitivity club and noise reduction set at?

            Comment


            • #7
              Audio sensibility clubs = 4db
              Audio noise reduction = 6db

              Use audio analyses = No (is it correct ?)

                There's your problem. Audio analysis needs to be on.

                  Yep. Try that and let us know.

                          When posting screen shots. Please don't post the whole capture with the desktop. Just select the part that we need to see and paste it into a new .jpg picture before uploading it.

                          In your Vcam, from what I can tell, the streak is not bright enough. You need to increase the gain and also reduce the minimum greyscale ball for the irons.

                            sorry about that.

                            If I read the instructions correctly, when you right click the window it says to subtract 20 from the shot color. Now when I put my cursor over my shot the number starts high and goes low. Does it matter where I select to determine the gray scale number?

                              Don't do that. Just increase the gain until your ball streak looks like mine. You'll have to rehit of course. Then reduce greyscall ball until you get the red line.
