Monocular vision

[GoldenWings]

I am working on similar project as my graduation project, but i was thinking to use lidar for measuring distances but the idea you use which called monocular sounds interesting besides lidars are pretty expensive, do you have any resources to read more about it? Because the obstacles detection part i was thinking of using tf object detection api so i dont know if the calibration technique would work eith that.

@GoldenWings From what I understand, you will still need to calibrate your camera to be able to perform the distance measurement. Distance measurement will take place in succession to the tf object detection api (as you would have identified your target object).

I would read the following articles to get a better intuition and detailed guidance on implementing monocular distance measurement and performing the camera calibration:

Hope this helps :)
