I'm trying to implement an object tracking in LabVIEW. I've written a VI (attached) to detect and locate the centroid of elliptical shapes (because my circular subject can possibly be rotated and appear as an ellipse). However, the detection is not successful on every frame.
For this reason, I would like to use the object detection method I've written as a ROI reference for an object tracker, whereby the object detector runs every 10-20 frames or so to make sure the tracker has not accumulated too much error. Any advice on how I can do this? Thanks!
Additionally, any criticism or advice on my object detection method would be appreciated.
We have started with the development of our own embedded MIPI camera module for the Raspberry Pi with an industrial image sensor. Currently we are in the specification phase and we are interested in your preferences so we will develop a product that does fit your requirements. If you have some time, please consider filling in this 4-question questionnaire.
I am new to the camera labview programming.
For my research work, I am using camera to grab the live image. I am stuck with one problem.
how to treat the background?
I tried to subtract the constant value from the entire image, but with that i am loosing few of my data.
I know one solution, but I don't know how to implement this solution.
Problem: how to take the values from the 4 corner of the image and subtract those value from entire image?
If anybody previously develop similar stuff then please help me out for this.
Any help would be appreciate.
Here, I have attached the VI in which I want to do auto exposure and set that exposure value.
Basically this is program for laser beam analysis on live image.
Basically I want to set exposure time accordingly laser beam intensity.
If anyone previously worked on it then please help me with that. I am new to image processing.
Other image I attached, that's the part I want to implement with this program.
Help me out to solve this problem.
Research purpose, I am using Imagining Source (DMK 33Ux249) camera to capture the laser beam. I am trying to write a code for auto exposure according to power level of laser beam. I used Vision acquistion for capturing live video image and tried to open the front panel of the vision acquistion.
But, I couldn't figure out how to set the exposure level automatically. Basically whole task is,
1. Capturing live image
2. set the exposure time according to laser beam profile
3. Remember the exposure the time and set again according to next frame or beam profile.
Is anybody previously work or have an idea to solve this issue please let me know.
