Embodiment Construction
[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0022] In the embodiment of the present invention, by setting multiple positioning cameras in different orientations of the preset scene, the moving objects captured by each positioning camera in the multiple positioning cameras are acquired. When the moving objects captured by each positioning camera in the multiple positioning cameras When the moving object is the same target moving object, then calculate the tracking coordinates of the target moving object, and send the tracking coordinates to the tracking camera, so that the tracking camera can track and shoot the target moving object; thereby r...

The present invention is applicable to the field of image processing technologies, and provides a moving object tracking method and apparatus. The method comprises: acquiring a moving object captured by each positioning camera of multiple positioning cameras in a preset scenario, wherein the multiple positioning cameras are located in different directions of the preset scenario; when the moving object captured by each positioning camera is a same target moving object, calculating tracking coordinates of the target moving object; and sending the tracking coordinates to a tracking camera, so that the tracking camera tracks and shoots the target moving object. The present invention implements tracking and shooting a moving object and dynamic switching an object for tracking and shooting. Further, the moving object is captured from different visual angles and dimensions separately by using positioning cameras in different directions, which effectively improves accuracy and anti-interference performance of outdoor class teaching video tracking. In addition, it is unnecessary to perform complex calibration and arrangement for the positioning cameras.
Description
technical field [0001] The invention belongs to the technical field of image processing, and in particular relates to a moving object tracking method and device. Background technique [0002] The scope of existing teaching venues continues to expand, and many classrooms have shifted from traditional indoors to outdoors, museums, conference venues, etc. Outdoor teaching and live video broadcasting have increased the sense of presence and interactivity of teaching quality to a certain extent. However, in the existing live video broadcasting of outdoor teaching, video recording and live broadcasting are mainly performed in a fixed-viewpoint mode. The circuit layout of the camera is complicated, immovable, poor in flexibility, and cannot dynamically track and switch teachers, students, and participants. Contents of the invention [0003] In view of this, embodiments of the present invention provide a method and device for tracking a moving object, so as to realize tracking and...
