Object detection and anchor location and directional resolution for augmented reality (AR) applications

A feature causing interest of an object within a physical environment is identified from a video of the physical environment. A model of the object is obtained, the model including a size of the object. A first array is maintained with pixel coordinates of identified features within the video. A second array is maintained with the dimensions of the features obtained from the model. A processing framework is provided for using the first array and the second array, and estimating, updating, and tracking anchor poses in the physical environment within the video as well as any AR-generated objects placed in the video. The framework is provided to an augmented reality (AR) app to initiate an AR session and maintain the session. 从物理环境的视频中标识所述物理环境内的对象的引起关注特征。获得所述对象的模型，所述模型包含所述对象的尺寸。用所述视频内的所标识特征的像素坐标来维护第一阵列。用从所述模型获得的所述特征的所述尺寸来维护第二阵列。提供一种处理框架，以用于使用所述第一阵列和所述第二阵列，并且估计、更新和追踪所述视频内的所述物理环境中的锚点姿态以及置于所述视频中的任何AR生成的对象。将所述框架提供到增强现实(AR)app以发起AR会话并且维护所述会话。
