Title: Oleksandr Dovzhenko: Innovator in Light Source Control and Depth Mapping

Introduction

Oleksandr Dovzhenko is a notable inventor based in Espoo, Finland. He holds three patents that showcase his expertise in light source control and depth mapping technologies. His innovative work has contributed significantly to advancements in user-interaction controllers and head-mounted devices.

Latest Patents

Dovzhenko's latest patents include a system for adjusting the brightness of light sources in a controller. This tracking system features light sources arranged spatially around user-interaction controllers of head-mounted devices. It incorporates a controller-pose-tracking mechanism and a head-mounted display (HMD) pose-tracking system. The processors are designed to estimate the relative pose of the controllers concerning the HMD, determine the current value or pulse width modulation (PWM) for controlling brightness, and generate control signals accordingly. Additionally, he has developed a method for creating depth maps and 3D reconstructions with segmentation masks. This method involves receiving visible-light images and corresponding depth data, identifying image segments that represent different material categories, and correcting errors in optical depths based on adjacent segments.
