## Description
Inside my school and program, I teach you my system to become an AI engineer or freelancer. Life-time access, personal help by me and I will show you exactly how I went from below average student to making $250/hr. Join the High Earner AI Career Program here 👉  (PRICES WILL INCREASE SOON)

You will also get access to all the technical courses inside the program, also the ones I plan to make in the future! Check out the technical courses below 👇

_____________________________________________________________

In this video 📝 we are going to see How To Estimate Depth with Stereo Vision in OpenCV Python with multiview geometry. we are going to combine pretty much all of the things that we have been through in the computer vision tutorial here on the channel. We will use mediapipe for face detection, calibrate our stereo cameras and then use multiview geometry to estimate the depth to the face we are detecting.
