Problems solved by technology

[0003] When there are many objects in the video stream, the number of objects in each frame of the video stream may change compared to the previous frame, and the position of the same object may also change. In order to accurately Marking the object information, the object recognition system will perform the above d

Example Embodiment

[0053] The exemplary embodiments will be described in detail here, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following exemplary embodiments do not represent all implementation manners consistent with the present invention. Rather, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0054] In order to be able to track the recognition object in each frame of the image in the video stream, it is not necessary to perform object recognition operations in each frame, such as figure 1 As shown, in an embodiment of the present invention, an object recognition and tracking method is provided. The object recognition and tracking method can be applied in a computer, and...

Abstract

The embodiment of the invention provides an object identifying and tracking method and device. The method comprises the steps that a current frame image to be identified is acquired in a video stream; an identified object in the current frame image is detected, and a detection box list is obtained; a superposition range of each first detection box and a corresponding second detection box stored in a preset object identification information table is determined according to each first detection box in the current frame image; and if any superposition range is greater than a first preset threshold value, it is determined that an object identifier corresponding to information of each first detection box is the same as an object identifier corresponding to information of the corresponding second detection box. Through the method, object identifiers of identified objects in the first detection boxes can be determined without the need for identifying images of the identified objects in the first detection boxes and the second detection boxes, time spent by a user waiting for an image identification result is saved, and the efficiency of identifying identified objects in all frame images in the video stream is improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to an object recognition and tracking method and device. Background technique [0002] The object recognition system based on the video stream is used to identify the objects appearing in the video stream and mark the object information around the object. In order to realize object recognition and information labeling, the object recognition system first detects the positions of all objects to be detected in each frame, identifies all objects in each frame through a specific object recognition algorithm, and then records them in the object feature database. The information related to each object is retrieved, and finally the object-related information is marked around the corresponding object. [0003] When there are many objects in the video stream, the number of objects in each frame of the video stream may change compared to the previous frame, and the position of the ...
