Title: Calanit Dotan: Innovator in Camera Calibration and Distance Measurement

Introduction

Calanit Dotan is a prominent inventor based in Tel Aviv, Israel. He has made significant contributions to the field of camera calibration and distance measurement, holding 3 patents that showcase his innovative approaches.

Latest Patents

His latest patents include "Camera calibration and distance measurement based on homography" and "Camera calibration and distance measurement using parallel lines." The first patent involves a method, apparatus, and computer-readable medium for estimating a real-world height in an image. This is achieved by obtaining two images of an object with a known height, where each image depicts the object at different positions estimated using a homography matrix. The homography matrix transforms an image plane associated with the image to a real-world plane. The implementation includes generating vectors that intersect with the object and point to a real-world ground plane, ultimately calibrating the camera by determining the height of the camera lens center.

The second patent focuses on estimating a real-world distance in an image. It involves obtaining an image from a camera installed in an environment and identifying sets of parallel lines on a real-world ground plane. The implementation includes determining intersection points of these parallel lines, identifying a ground line connecting these points, and estimating an internal camera matrix based on the camera's focal length and image size. This process allows for accurate camera calibration for real-world distance measurement.
