Problems solved by technology

However, the scheme based on motion detection is very sensitive to changes in the picture. In real scenes, there are likely to be a lot of changes in the picture, but most of the changes are not effective. The movements of characters in classrooms or conference rooms are very frequent and disorderly. It is difficult to obtain accurate behaviors from rough and simple optical flow or frame difference features

Embodiment 1

[0028] figure 1 This is a method flowchart of a shooting method based on standing behavior detection provided in Embodiment 1 of the present invention. This embodiment can be applied to recording and broadcasting systems such as teaching and conferences. The method can be executed by a smart camera with a PTZ, Specifically include the following steps:

[0029] Step 110 , according to the track image list, quickly filter out a person target that has a standing up behavior in the current frame image according to a preset rule. Wherein, the track image list consists of track image sequences of all human objects.

[0030] Step S110 performs preliminary screening on a large amount of data. For example, there may be dozens or hundreds of people in a classroom. Most of the useless data can be excluded through the preliminary screening. The character target with standing up behavior can be precisely locked on the character target through the trajectory, thereby realizing the precise...

Embodiment 2

[0038] figure 2 A method flowchart of a shooting method based on standing-up behavior detection provided in Embodiment 2 of the present invention. This embodiment can be applied to teaching, conference and other recording and broadcasting systems. The method can be executed by a smart camera with a PTZ, Specifically include the following steps:

[0039] Step 210 , according to the track image list and according to preset rules, quickly filter out the character targets that have standing up behavior in the current frame image.

[0040] Step S210 performs preliminary screening on a large amount of data. For example, there may be dozens or hundreds of people in a classroom. Most of the useless data can be excluded through preliminary screening. The character target with standing up behavior can be precisely locked on the character target through the trajectory, thereby realizing the precise closed-loop control of the zoom and the gimbal, and the trajectory-based analysis can mo...

Embodiment 3

[0076] Image 6 This is a flowchart of a method for a shooting method based on standing-up behavior detection provided in Embodiment 3 of the present invention. This embodiment can be applied to recording and broadcasting systems such as teaching and conferences. The method can be executed by a smart camera with a PTZ, Wherein, step S310, step S320, step S340, step S350, step S360 and step S370 in this embodiment are the same as steps S210 to S260 in the second embodiment, and the specific implementation can refer to the corresponding content of the second embodiment of the present invention , which will not be repeated here. The difference between this embodiment and the second embodiment is that step S320 is further included after step S330. If it is detected that the character target with standing up behavior has a sitting behavior or is lost, it will continue to be quickly screened out according to the preset rules according to the track image list. In the next frame of i...

Abstract

The invention discloses a shooting method and system based on standing behavior detection. The shooting method based on standing up behavior detection includes: according to a track image list according to preset rules, quickly screening out a character target with a standing up behavior in the current frame image; wherein, the track image list is composed of the track image sequence of all the character targets; using The visual classifier based on the deep learning neural network determines the character target with effective standing up behavior according to the trajectory image sequence corresponding to the screened character target; controls the camera to lock the character target with effective standing up behavior; Close-up shot. The present invention can accurately and efficiently detect a character target with an effective standing up behavior, and perform a focused close-up shooting on the corresponding character target, thereby greatly improving the user experience.

Description

technical field [0001] Embodiments of the present invention relate to the field of photographing technologies, and in particular, to a photographing method and system based on standing-up behavior detection. Background technique [0002] In the recording and broadcasting system, such as teaching, meetings, etc., it is necessary to take close-up shots of some prominent target people or target behaviors, especially when the target person stands up, the shooting equipment needs to take a close-up shot of the target person. When the target person sits down , the shooting device returns to the wide-angle position, monitors the standing behavior of the target person in real time, and focuses on the target person for close-up shooting after identification. [0003] In the prior art, the frame difference method or the optical flow method is mainly used to realize the principle of motion detection. After the approximate motion range is obtained through these two methods, the photogra...
