VI TO DETECT MOTION

[SATISH_BMS]

 Hello Every one I am very very new to programming in labview. I reqd anybody,s help.

1. I have labview evaluation version.

2. My project involves motion detection.

3. On detection of motion a signal has to be transmitted to serial port.

Please help me in this regard.

Is this a school project?

What kind of sensor are you using for motion detection? How  will you get the data from the sensor to the computer?

What is the format or content of the signal to be sent on the serial port?

A good place to start is with the on-line LabVIEW tutorials.

Specifically, what kind of help do you want?  Are you an experienced programmer but new to LV or new to all kinds of programming?

Dear Sir, Thanks for your kind reply

1. This is job related project. the project involves automatically firing a dummy gun using mechanical assembly by using UV transceivers. I am using 89s51 microcontroller.

2. Since the reqmt of the range is more. I have to go for live video capturing using imaging device.

3. My requirement is that on any detection of motion a signal in the form of a Character say 'A' in ASCII to be sent to serial port, which i will be used by the microcontroller to trigger.

4. I am very new to labview. I have  done little bit coding experience in C lang.

5. I am using evaluation version of Labview 2011 and vision acqusition software.

6. I want to in the acquire images from webcam for timebeing and find any detection on motion.

I suggest that you post to the Machine Vision Board.  Motion detection from video images is a specialized field and posting on that board is more liekly to get the attention of those with the needed expertise.

Once you have detected the motion, sending a message is straightforward. Use the VISA Serial Write VI.

Thanks john ....... a lot

For sure check out the machine vision boards. 

NI's smart cameras are pretty easy to program and can do serial I/O on board.  They're worth looking into.
