Robots see the world as points.

I'm Abdullah Erzin, a computer vision engineer. I make those points accurate enough for a robot arm to pick fruit off a tree, outdoors, in sunlight. Now at Pek Automotive in Logatec, Slovenia.

Colour is distance: near is red, far is blue. Move the pointer to look around.Press and hold anywhere to see what the camera sees. Scroll to rebuild the next scene.

Perception to picking

I took over a multi-arm apple and orange harvester that was not operational and made it field-ready: calibration, detection, depth and the picking logic that decides which fruit comes next.

Camera to arm, within tolerance

A three-stage calibration replaced a manual procedure: polynomial regression per arm, a misalignment correction, and compensation for the camera tilting as the arm extends.

The front of the fruit, not the peak

Peak depth inside a fruit mask lands behind the fruit. A front-surface search fixed it, exposure now follows the sun, and YOLO was retrained on occluded clusters.

A face has depth. A photo does not.

Stereo liveness built from scratch: depth at facial keypoints tells a real face from a printed one. Turn the view and the photo goes flat.

Cracks you cannot see, by how heat leaves

A TUBITAK-funded project I led: flash-heat a PLA part, film it cooling, and use the Fourier phase of every pixel to find hidden cracks and estimate how deep they are.

Backprop and attention, by hand first

To understand the models I use every day, I worked through deep learning from the maths up. The project page has a gradient step and an attention matrix you can play with.
