How to take Webcam photos automatically?

Hello world

the idea is to program a camera that will be used as a bar code reader.

Using the read codes function bar Vision I managed to take a picture of the webcam, display the image and read the barcode, however I have to take the image manually.

I want my camera to take the picture of the bar code automatically when I put a code bar in front of her.

How could I do this programmatically?

Thank you for your support,

KevinCoder

Hey Kevin,

by manually, I assume you mean, push a button in LabVIEW, to take a picture.

To start with the bar code, you can snap and analyze in a loop, until the output is logic, and then continue the processing of your data. This could be treated beautifully in a state machine.

    Thank you

    Hi avroom,

    First of all, make sure that the camera software is installed and configured on the computer.

    1. open the Capture Cam life User Interface by clicking on the Microsoft LifeCam shortcut on your desktop or by clicking Start, all programs , then Microsoft LifeCam.

    2. take a picture with the Cam of life by clicking on the camera icon in the Capture User Interface (1).

    For more information on the web camera, you will need to download the documentation for the device and check the characteristics later.

    Easiest is to copy the files with a USB key, but the most elegant (IMHO) is across the network. Just join each machine to your homegroup, and you can copy back.

  • How to take a photo from facebook and download it to my photos?

    I want to take a photo from facebook and save it in my files. How can I do this?

    Honestly, I don't think that it is more difficult to tell you how to save pictures, it is to find a specific article and put it in.

    Click with the right button on the image, select Save image as, choose where you want to save and click Save.

    Is it really so hard to tell who?

  • How to take the photo and prepare it in photoshop to bring it to the animation of the character?

    Hello

    I want to take a picture of a Denis and do animation

    How to prepare the image that it will work well in the new CHARACTER ANIMATION software?

    Thank you!

    Pictures tend to look scary when driven by HP, because of the "uncanny valley" effect But if you're brave, here's the general idea:

    (1) open the photo in photoshop, put on another layer

    (2) select the right eye, cut it into a new layer, name it + right eye

    (3) turn the eyeball to this new layer that you can see the underlying face

    (3) command-clicking the icon of the right eye to make the selection of the shape of the eye

    (4) select the face layer and shift + delete to remove the eye, choosing Content-Aware Fill to get skin to fill in where the eye was

    Repeat for each part of the body you want individual control on (see the puppet of model by file > new puppet in Photoshop for all names special to use for the auto-rigging)

  • How to take 2 photos and 1 split screen pic do?

    I need to take 2 pictures and place them side by side in 1 pic. As a side-by-side comparison. Using Photoshop Elements 13

    1. Open the editor in the Expert tab
    2. Go to the file menu > New > empty file. Enter the values of H & W, resolution, background color. It will be the canvas for the 2 pictures and appear in the layers palette in the background layer.
    3. Open A drawing, go to "Select" menu >, go to the Edit menu > copy to the Clipboard
    4. Return to the empty layer, and then tap Edit > paste. Use the move to position A tool and resize with the corner of the frame handles encompassing, if necessary.
    5. Do the same for the B picture.
    6. You should have 3 layers: background and with A image and layer with photo B.

    TIPS:

    I guess you want to print it. Do the math, review your paper stock and calculate the optimal size for each photo. You will have to perhaps crop or resize the images for a good fit.

    In the field of the resolution to the step above #2, it is desirable to have the resolution of the empty file identical to the resolution of the photo files. You can check the resolution by Image > resize > Image size...

    For printing, the resolution in the range 240-300px in generally gives an acceptable result. For web work, 72px / is ok.

    Please note the last changes you make on your computer will be automatically saved on your computer and which will be unchanged, unless you change it again on your computer.

    When photos are automatically get stacked?  If you are referring to raws automatically get associaterd with their correspondents of JPEG files when you import, you can disable that by checking the option preferences > process files Next To Raw files as separate Photos JPEG.

    If this isn't what you're referring, please provide information on what you are watching - what types of photos are getting stacked, when stacking occurs it, what version of LR (help > System Info).

  • How can I get photos of photo shopped for transfer and print at Wal-Mart booth? They will appear once I take SD

    How can I get photos photo shopped to transfer and on the SD card appear in places like Wal-Mart to print?

    It may depend on the kiosk. Older models, I had to use the software provided with the camera and transfer to the camera. Then the kiosk would read the card.

    This last time I tried a month ago, I was able to use a flash drive and he could read the image in the root folder. He acknowledged the files both jpg and png.

    If all fails you can download via their website and pick them up at the store. Or I guess the download is always available, been awhile.

  • How long they durent photos on a locked phone

    Hello

    Today I came home to realize that I just left my iphone 6s at home of my Nana. I don't rely on my phone as much as other people might so I'm not really in a super big rush back, but I don't forget things. Today, I took some photos of embarrassing myself, as do most of the people (don't worry nothing innapropriate). I have a password on my phone and sometimes I'm too lazy to unlock my phone just to take a picture, then I'll click the camera on the home page. I understand that when you take a picture on the homepage icon, you can see the pictures, but what worries me is, how long are pictures stored on the home page of the camera mode until they are removed from this area? The thing is, I'm 15 years old and I have an aunt and sometimes his 21 year old daughter go his house too and I'm just worried, because they are the kind of people to go on my phone and get a discount of it. She is pretty tech savvy and I wouldn't put in front of her to take a look to see if there is pictures there. As much as I am much younger than my cousin, I think she can be jealous because I have the iphone 6, when she was 5 and think maybe I'm perhaps too immature? They might think that it is acceptable to use my phone? (I know that I would not do the same thing and I respect the privacy of someone). As we have a little family fracture.

    Long story short, how long is the last equipped locked camera? It's 24 hours from picture taken because I want to know if my family see it.

    Sorry to make this longer post than what he must do.

    Thank you

    I just tried on my 5s, take a photo using the camera, again, lock screen application, then wake up the phone once again, drag the icon of the camera upward to open the camera application. There is no last picture to be seen in the left corner, and if you tap on this gray square, the lock screen appears, asking for the password to the lock screen.

    So, on this side you should be sure

  • How can I stop Photos to start when I plug my iPod nano?

    How can I stop Photos to start when I plug my iPod nano?  I use mac os x El Capitan 10.11.3 & iTunes 12.3.2.35.

    It takes your iPod nano 5th generation.  If so, this happens because he has a camera.  After Photos opens when you connect iPod, near the top of the window, is there a checkbox to Open the Photos for this device (or words to that effect)?  If you see this checkbox, uncheck.  Photos should be open when the iPod is connected.
