Technical issues: 1. Image Processing
2. Speed of processing
4. serial port communication
Cost: cost of two webcamera
1. One day if you happen to know how to do image processing in MATLAB
2. If you don’t know how to do image processing in MATLAB the it will take almost 3 weeks to learn image processing from scratch. However you don’t need to learn mathematical concepts of image processing.
Where to get things : Multiplan/rifels square/ Bashundhara city.
