Method and device for determining scale parameters of augmented reality map

The embodiment of the invention provides a scale parameter determination method and device for an augmented reality map, and the method comprises the steps: carrying out a VIO test in a same scene through a mobile device provided with a visual inertial odometer VIO, and obtaining an image sequence of a current scene and a pose sequence with a real world scale; performing image matching and PNP calculation on the image sequence and an augmented reality (AR) map to obtain a pose sequence of the image in the original map scale in the current scene; determining scale parameters of the AR map according to the pose sequence of the real world scale and the pose sequence of the original map scale; the method is not limited by outdoor scenes, the data required for obtaining the scale of the AR map can be obtained only through the mobile equipment with the VIO function, the accurate scale parameters of the AR map can be stably obtained, and the AR application can provide good experience for users. 本申请实施例提供一种增强现实地图的尺度参数
