Embodiment 1

[0021] Embodiment 1 of the present application provides a tracking state determination method, figure 1 It is a schematic flow chart of a method for determining a tracking state provided by an embodiment of the present application.

[0022] In this embodiment, the method for determining the tracking state described above can be applied to various shooting devices or any electronic device with a shooting function, for example, it can be applied to portable shooting devices such as pocket cameras, sports cameras, and hand-held cameras, and can also be applied to portable shooting devices with Electronic devices such as smartphones and tablets with shooting functions are not limited by the present invention.

[0023] As shown in the figure, the method for determining the tracking state in the embodiment of the present application mainly includes the following steps:

[0024] In step S11, the tracking information of the tracking target is obtained according to the state identific...

Embodiment 2

[0039] figure 2 A schematic flowchart of the method for determining the tracking status according to Embodiment 2 of the present application is shown.

[0040] In this embodiment, the sequence of captured images includes a plurality of consecutive captured image frames, correspondingly, figure 1 The shown step S11 includes the following steps:

[0041]Step S111, identifying the tracking target in each captured image frame in the captured image sequence, and obtaining the tracking identification result of the tracking target in each captured image frame.

[0042] In one embodiment, the process of determining the tracking target may include: firstly identifying at least one object in the captured image frame, and then determining, among the identified at least one object according to the user selection instruction, the One subject is used as the tracking target.

[0043] In another embodiment, the process of determining the tracking target may include: first identifying at l...

Embodiment 3

[0049] Figure 4 A schematic flowchart of the method for determining the tracking state according to Embodiment 3 of the present application is shown.

[0050] Please refer to figure 2 and Figure 4 , in this embodiment, the state identification information corresponding to the tracking target includes one of the first identification information (such as an untrusted state) and the second identification information (such as a trusted state). Correspondingly, figure 1 The shown step S12, that is, updating the state identification information corresponding to the tracking target according to the tracking information may include the following steps:

[0051] Step S41, identify the state identification information corresponding to the tracking target, that is, determine which tracking state the tracking target is currently in, and choose to execute one of step S42 or step S43 according to the identification result.

[0052] Step S42, when the state identification information c...

Abstract

The embodiment of the invention provides a tracking state determination method and device and a handheld camera. The method comprises the steps of tracking state identification information corresponding to a target, obtaining tracking information of the tracking target, and using the tracking information for identifying the follow-up identification result of the tracking target in the shot image sequence, a follow-up loss identification result of the tracking target in the shot image sequence which is not continuously followed up, or a searched identification result of the tracking target in the shot image sequence; and updating the state identification information corresponding to the tracking target according to the tracking information so as to reduce the probability of tracking failureof the tracking target.

Description

technical field [0001] The embodiments of the present application relate to the technical field of computer vision, and in particular to a tracking state determination method, device, and hand-held camera. Background technique [0002] Object detection and tracking system is a direction of rapid development in the field of computer vision in recent years. With the development of visual processing technology and artificial intelligence technology, hand-held cameras can be used to track the target to be photographed, and perform operations such as object recognition and scene recognition based on the target to be photographed, so that users can classify and compare the photos or videos taken. management, and other subsequent automated processing operations. [0003] However, compared with industrial cameras, existing household handheld cameras (smart cameras) often need to obtain panoramic images by constantly changing shooting positions due to the relatively limited field of...
