sensors miniproject help

Hello, As part of my sensors class in college, I have to do a miniproject, my group is doing a landmine detection system, Here are the details: We plan to use a custom metal detector as the primary sensing element, that will be mounted above a model field (simulating a drone essectially) a camera module will capture an image of the field and create a coordinate system, then a directional metal detector will find potential landmine locations and map them to the picture taken, then the system should display a list of coordinates This is the plan anyway, we have 5 weeks till the submission, I got a rasberry pi 4b 1gb from a senior for cheap and we plan to use that as a microcontroller, the other teams aldready have a head start on us, so I would appreciate any help on this project, it's my first time working with a microcontroller so I don't know how to do the connections properly or whatever, im not sure whether all the computation can be done with the rasberrry pi or if I will need any other components, I would also Appreciate any feedback or recommendations for the project
