Embodiment 1

[0044] figure 1 It is a flow chart of the target tracking method provided by Embodiment 1 of the present invention. The object tracking method is applied to a computer device.

[0045] The target tracking method of the present invention tracks a specific type of moving object (such as a pedestrian) in a video or image sequence, and obtains the position of the moving object in each frame of image. The object tracking method can solve the disadvantage that the existing solutions cannot track the high-speed moving object, and improves the robustness of the object tracking.

[0046] Such as figure 1 As shown, the target tracking method includes:

[0047] Step 101, using a target detector to detect a target of a predetermined type in a current image to obtain a first target frame in the current image.

[0048] The predetermined types of objects may include pedestrians, cars, airplanes, boats, and the like. The predetermined type of target may be one type of target (such as ped...

Embodiment 2

[0093] figure 2 It is a structural diagram of the target tracking device provided by Embodiment 2 of the present invention. The target tracking device 20 is applied to a computer device. The target tracking of this device tracks a specific type of moving object (such as pedestrians) in a video or image sequence, and obtains the position of the moving object in each frame of image. The target tracking device 20 can improve the robustness and scene adaptability of target tracking. Such as figure 2 As shown, the target tracking device 20 may include a detection module 201 , a prediction module 202 , a matching module 203 , and an update module 204 .

[0094] The detection module 201 is configured to use a target detector to detect a target of a predetermined type in the current image to obtain a first target frame in the current image.

[0095] The predetermined types of objects may include pedestrians, cars, airplanes, boats, and the like. The predetermined type of target...

Embodiment 3

[0140] This embodiment provides a computer storage medium, on which a computer program is stored. When the computer program is executed by a processor, the steps in the above embodiment of the target tracking method are implemented, for example figure 1 Steps 101-104 shown:

[0141] Step 101, using a target detector to detect a predetermined type of target in the current image to obtain a first target frame in the current image;

[0142] Step 102, acquire the second target frame in the previous frame image of the current image, use a predictor to predict the position of the second target frame in the current image, and obtain the position of the second target frame in the current image the prediction box in the image;

[0143] Step 103, matching the first target frame in the current image with the predicted frame to obtain a matching result between the first target frame and the predicted frame;

[0144] Step 104: Update the position of the target in the current image accord...

Abstract

The invention belongs to the technical field of image processing, and provides a target tracking method and device, a computer device and a storage medium. The target tracking method comprises the following steps: detecting a predetermined type of target in a current image by using a target detector to obtain a first target box in the current image; Obtaining a second target frame in the previousframe of image of the current image, and predicting the position of the second target frame in the current image by using a predictor to obtain a prediction frame of the second target frame in the current image; Matching a first target frame in the current image with the prediction frame to obtain a matching result of the first target frame and the prediction frame; And updating the position of atarget in the current image according to a matching result of the first target frame and the prediction frame. According to the invention, the robustness and scene adaptability of target tracking areimproved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a target tracking method, device, computer device and computer storage medium. Background technique [0002] Object tracking refers to tracking moving objects in video or image sequences (such as cars and pedestrians in traffic videos) to obtain the position of moving objects in each frame. Object tracking has a wide range of applications in video surveillance, autonomous driving, and video entertainment. [0003] The current target tracking mainly adopts the track by detection architecture. The position information of each target is detected by the detector on each frame of the video or image sequence, and then the target position information of the current frame is compared with the target position information of the previous frame. match. However, the robustness of object tracking in existing schemes is not high, and the tracking effect is not good if the il...
