to mark as completed 3D coordinate estimation. (ANN)
Hi everyone, this is the 1st time I joining LMR!
Here I want to share my previous project on computer vision. It used a laser pointer, a camera and servos to make it work.
What Happen??
Camera try to detect any object that we want using image processing(eg video: external object from monitored area), than MATLAB controlling the 2 axis servo in pointing the laser point on the detected object by the help of Fuzzy Logic controller. Then it come to the idea, I used the value of each servo rotation and the pixel object coordinate in the image captured,and the actual 3D coordinate of the object as a training input data to the ANN(Artificial Neural Network). After few time training, the system it self able to estimate the object coordinate.
The estimation is not really precise, but just to realized the idea into real world. =) Feel free to comment.
*This is my first time, anything I do wrong, let me know so I can improve.
