It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of an output method of an audio signal of a camera according to an embodiment of the present disclosure, where the present disclosure is applicable to a situation where a video is played after a video is recorded by a camera, and the method may be executed by an output apparatus of an audio signal of a camera according to an embodiment of the present disclosure, where the apparatus may be implemented by software and/or hardware, and may be integrated in a device such as an intelligent terminal for playing a video.
As shown in fig. 1, the method for outputting the camera audio signal includes:
s110, acquiring a video image shot by a camera, and determining whether monitoring personnel exist in the video image.
The camera may be a camera installed at a fixed position, for example, a camera for security protection, or may be a camera that can be moved, for example, held by a user or fixed on a vehicle, to capture a video. The shot images of the video can be a certain number of continuous images, or images of extracting one frame at intervals of a certain number of frames.
In this embodiment, whether the monitoring person exists in the video image may be determined through image recognition, feature comparison, and other techniques. For example, a camera installed at the doorway of a cell, there may be a certain time when no person passes, and there may be 1, 2 or more persons passing at the same time. In each case, the front end of the camera or the back end for playing the video may employ corresponding techniques to identify whether monitoring personnel are present in the video image, and the number of monitoring personnel present.
In this embodiment, the camera includes at least two audio capturing devices, the distance between the camera and the audio capturing devices may be determined according to the setting positions of the audio capturing devices, for example, a microphone may be respectively disposed at 0.5 meter on the left and right sides of the camera. Four microphones can also be arranged at the positions of 0.3 meter from top to bottom, left to right. The arrangement position of the audio acquisition device, that is, the microphone, may be preset according to the requirement of the user.
In this embodiment, optionally, before acquiring a video image captured by a camera and determining whether a monitoring person exists in the video image, the method further includes: and determining the mapping relation between each area in the monitoring range of the video image and the audio acquisition devices according to the number and the relative positions of the audio acquisition devices of the camera.
With reference to the above example, if the number of the audio capturing devices is 2, and the relative positions are 0.5 meters each disposed at the left and right of the camera lens, it may be determined that the monitoring range of the video image includes two regions, and the two regions are obtained by vertically splitting the middle position of an image, where the left region corresponds to the left audio capturing device, and the right region corresponds to the right audio capturing device. Through the arrangement, the binding relationship can be formed between each region in the monitoring range and the audio acquisition device for acquiring the audio in the region more clearly. For example, when monitoring personnel exist in the left half area in the monitoring range, and when the monitoring personnel make a sound, the audio acquisition device arranged on the left side can acquire audio information more clearly. According to the scheme, through the establishment of the mapping relation, a data basis can be provided for subsequent output audio signals, the output audio signals are ensured to be more targeted, and the audio quality of the shot video is improved.

The areas may be divided in advance according to the set number and the set position of the audio acquisition devices, or may be obtained directly by a worker according to a predetermined association relationship. Because the size of a person in a video image is influenced by a perspective principle, if the distance is short, the image of the person in the monitored range is larger, and therefore the position of the monitored person can be determined more specifically according to the position of the face.
And S130, determining the audio acquisition devices corresponding to the areas where the monitoring personnel are located according to the preset mapping relation between each area and the audio acquisition device.
After the area where the monitoring person is located is determined, the audio acquisition device corresponding to the area where the monitoring person is located can be determined according to the preset mapping relationship between each area and the audio acquisition device. For example, if the monitoring person is currently on the left side of the video image, it is determined that the audio acquiring device corresponding to the area is the audio acquiring device arranged on the left side.
In this embodiment, optionally, before determining the audio acquiring device corresponding to the area where the monitoring person is located according to the preset mapping relationship between each area and the audio acquiring device, the method further includes:
determining the number of monitoring personnel in the video image;
and if the number of the monitoring personnel is at least two, determining the basic characteristics of each monitoring personnel to number each monitoring personnel respectively.
In this case, the number of each monitoring person may be determined according to the basic features of each monitoring person, for example, the difference of the facial features of each monitoring person, and the area where the monitoring person is located and the corresponding audio acquisition device are determined for the monitoring persons with different numbers. According to the scheme, the audio acquisition devices can be directly and respectively determined according to the conditions of a plurality of monitoring personnel, so that the source of the actually adopted audio signal is determined, and the effect of clear audio which can be output by each monitoring personnel in the monitoring range is achieved.
S140, if the selection operation of the target monitoring personnel is detected, determining a target audio acquisition device associated with the area where the target monitoring personnel is located, and taking the audio signal of the target audio acquisition device as an output audio signal.
The face information of the monitoring person can be selected from a Web interface, an application program or an applet, and the selection operation of the target monitoring person can be determined to be detected. According to the face information selected by the user, the area of the monitoring person in the video image can be determined, and further, the target audio acquisition device associated with the area can be determined.
After determining the target audio capturing device, for example, the microphone on the left side of the camera, the audio signal of the target audio capturing device may be used as the output audio signal. That is, after the user clicks the monitoring target, the microphone of the audio output may be determined according to the position of the monitoring target. Through the arrangement, the audio acquisition device resource of the camera can be fully utilized, and the effect of improving the audio quality of the shot video is realized.
