Patent number: 12039898Abstract: In AR glasses, an incident angle calculation unit calculates first and second angles of incidence of first and second markers, respectively, to an imager relative to a reference line in the real world in accordance with image plane coordinates of the first and second markers in the image captured by the imager. A separation distance calculation unit calculates a camera-to-marker distance, which is a distance from the imager to the first marker, in accordance with the calculated first and second angles of incidence, and an inter-marker separation distance between the first and second markers along the reference line in the real world. A display adjustment unit adjusts a projection position and size of the AR image with respect to the first marker in the image plane coordinates in accordance with the camera-to-marker distance.Type: GrantFiled: November 21, 2022Date of Patent: July 16, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hideki Kobayashi, Takayuki Aoki, Ryusuke Ohta, Hitoshi Muraki, Tomohiro Inada
