摘要： The present application is applicable to the field of video processing. Provided are a target tracking method for a panoramic video, a readable storage medium, and a computer device. The method comprises: using a tracker to track and detect a target to be tracked to obtain a predicted tracking position of said target in the next panoramic video frame, calculating the reliability of the predicted tracking position, and using an occlusion detector to calculate an occlusion score of the predicted tracking position; determining whether the reliability of the predicated tracking position is greater than a preset reliability threshold value, and determining whether the occlusion score of the predicted tracking position is greater than a preset occlusion score threshold value; and using a corresponding tracking strategy according to the reliability and the occlusion score. By means of the present application, whether a tracking failure is caused by the loss of a target or occlusion can be determined, such that a corresponding tracking recovery strategy can be used, and tracking can be automatically recovered when tracking fails, thereby achieving the effect of performing tracking continuously for a long time. In addition, the method of the present invention has a low operation complexity and a good real-time performance.

摘要： The present invention provides a horizontal calibration method and system for a panoramic image or video, and a portable terminal. The method comprises: receiving images or video frames of two circles after being imaged by two cameras having opposite photographing directions; obtaining a horizontal calibration matrix during photographing; and pasting, according to the horizontal calibration matrix, the images or video frames of the two circles to a left hemispherical curved surface and a right hemispherical curved surface of a spherical panoramic mathematical model in a UV mapping manner, respectively so that the panoramic images or video frames pasted in the spherical panoramic mathematical model are horizontal. According to the present invention, when an image or a video frame photographed by a panoramic camera is not horizontal, the panoramic image or the video frame pasted in a spherical panoramic mathematical model is still horizontal.
