Suggestion needed: chips can handle simple image processing

kentigens

Hi, I am a student whos trying to achieve some camera tracking and speed control of a trolley.
and I am kinda lost, dont know where to start with, hence urgently need experts advice.(supervisor couldn't help much)
Could someone please suggests me where to look at or any product thats available off the shelf ?
- a chip or ready off shelf processing unit which could do simple image processing, in real time. - and also associated software needed for the coding part?

Anyone know if this can be achieve within a couple of thousand dollars?

Thank you.
