Image positioning method and device based on rotating antenna and terminal equipment

Abstract

The invention is suitable for the technical field of indoor positioning, and provides an image positioning method and device based on a rotating antenna. The method comprises the steps: measuring a tag phase value through a radio frequency antenna rotating around a camera device, and recording a rotation angle corresponding to the radio frequency antenna when the tag phase value is measured; calculating the arrival angle of the tag according to the tag phase value and the rotation angle, and determining the actual position of the tag according to the arrival angle of the tag; and according to a preset mapping relationship, mapping the actual position of the tag to an image acquired by the camera device so as to determine the position of the tag in the image. According to the invention, pixel-level calibration of the image can be realized conveniently, quickly and accurately. 本申请适用于室内定位技术领域，提供了基于旋转天线的图像定位方法及装置，包括：通过围绕摄像设备旋转的射频天线测量标签相位值，并记录测量所述标签相位值时所述射频天线对应的旋转角度，根据所述标签相位值以及所述旋转角度，计算标签的到达角，根据所述标签到达角确定标签实际位置；按照预设映射关系，将所述标签实际位置映射到所述摄像设备获取的图像中，以确定所述标签在所述图像中的位置。本申请能够方便、快捷以及准确的实现图像的像素级标定。
