His innovative work has advanced the technology used in various applications, enhancing the capabilities of tracking systems.

Latest Patents

One of Yasushi Sumi's latest patents is a method and system for detecting the pose of a marker. This pose detecting system includes a marker that utilizes a microlens array, a camera, and a computer that receives a marker image. The marker is designed with a lens area made up of the microlens array and a mark array that features multiple marks arranged in a specific pitch. This configuration produces a moiré pattern, which is essential for determining the pose of the marker based on four reference points. The computer analyzes the moiré pattern to calculate the angle formed by the marker and a straight line connecting the center of an integrated mark to a viewpoint at the marker, allowing for pose correction.

Another notable patent by Sumi is an object tracking apparatus and method. This system is capable of tracking an object with an unknown initial position that is continually moving. It includes an observing device, such as a video camera, which captures scenes at a video frame rate. The apparatus processes time-sequentially acquired image data, enabling it to recover tracking processes even when tracking has failed. The object recognition module selects a frame memory based on predetermined information, and the movement tracking module updates the position and posture of the object by comparing image data with the object model.
