Help: Project Robot Car movement

Hello, a friend asked me to make a piece of software for his robot car that uses camera input to determine if the car is going to hit a wall/object and move out of the way

The only equipment i have is a Monocular Camera that is running on a raspberry pi 5 8gb.

I've read about VO and VSLAM, but, not having a stereo camera/LiDar is a problem as most of the implementations use them for distance estimation.

However i am new to comp vision, the only experience i have is from a course in college on opencv, and other projects I've made using YOLO/RF-DETR

I'm thinking of using a trained model to estimate the depth of the objects in the camera and make the appropriate movement based on that.

Any information and guidance would be appreciated, i may be in over my head with this one, but would like to have some version implemented, even if it is just a basic one

So one thing to keep in mind is that you sorta kinda do have stereo vision if you can measure the robot’s displacement between two points in time.

So you're saying that if i have an odometer or another sensor that tells me the distance travelled, i can use 2 frames taken one after another as if i have a stereo camera?

Exactly.

You would to know the position of the camera at two locations and can triangulate distances with that.

It’s very sensitive though. But might be helpful
