Zusammenfassung:To provide a device and method for visualizing a dead angle region of a vehicle.SOLUTION: An electronic apparatus includes a processor which determines a first transformation matrix of a camera coordinate system including a rotation matrix and a translation matrix to movement of a vehicle between two time points on the basis of two video images photographed at the two different time points by a camera of the traveling vehicle and traveling information of the vehicle, converts the first transformation matrix to a second transformation matrix of a vehicle coordinate system, updates a parameter of the camera so as to reflect the movement of the vehicle in the parameter of the camera on the basis of at least one of roll information and pitch information of the vehicle acquired from the rotation matrix, and uses the updated parameter and the second transformation matrix to visualize a dead angle region of the camera on the basis of at least one of the roll information and the pitch information.SELECTED DRAWING: Figure 4 【課題】車両の死角地帯の視覚化装置及び方法を提供する。【解決手段】電子装置は、走行中である車両のカメラで異なる2つの視点(two time points)で撮影された2つの映像及び前記車両の走行情報に基づいて、前記2つの視点間前記車両の動きに対する回転行列(rotation matrix)及び移動行列(translation matrix)を含む前記カメラ座標系の第1変換行列を決定し、前記第1変換行列を車両座標系の第2変換行列に変換し、前記回転行列から取得した前記車両のロール情報及びピッチ情報のうち少なくとも1つに基づいて、前記車両の動きを前記カメラの前記パラメータに反映するように前記カメラのパラメータをアップデートし、前記アップデートされたパラメータ及び前記第2変換行列を用いて、前記カメラの死角地帯を前記ロール情報及び前記ピッチ情報のうち少なくとも1つに基づいて視覚化するプロセッサを含む。【選択図】図4
