Referring to fig. 1, a flowchart illustrating steps of an embodiment of an information collecting method according to the present invention is shown, where the information collecting method is applied to an information collecting system, and the method may specifically include the following steps:
The information acquisition system can firstly generate shooting parameter adjusting signals based on the environment state and the shooting requirements, and adjust the shooting parameters of the cameras in the camera matrix according to the shooting parameter adjusting signals. The camera matrix comprises at least two cameras, and the at least two cameras are arranged according to a preset mode. The preset mode can be determined according to shooting requirements, for example, if information of different areas needs to be acquired for a preset scene, at least two cameras can be arranged at different positions; or, if the main top view needs to be acquired for a certain three-dimensional object, the two cameras can be arranged at corresponding shooting angles; or, if a panoramic image needs to be generated for a preset scene, at least two cameras may be arranged in a horizontal arrangement mode, a vertical arrangement mode, a planar arrangement mode or a distributed matrix arrangement mode, and shooting areas corresponding to two adjacent cameras have overlapping portions. Of course, the at least two cameras may be arranged in other ways, which are not further described here.
The shooting parameter adjusting signal comprises a target shooting parameter, and when shooting parameters of at least two cameras are adjusted according to the shooting parameter adjusting signal, the shooting parameters of the at least two cameras can be uniformly adjusted to be the target shooting parameter, wherein the target shooting parameter can comprise at least one of target brightness, target chromaticity, target hue, target focal length, target RGB component, target shutter speed, target gain and target white balance.
By uniformly adjusting the shooting parameters of the at least two cameras, the defect of inconsistent parameters caused by one-by-one adjustment can be avoided, and the at least two cameras are ensured to correspond to the same shooting parameters so as to keep the consistency of the shooting parameters of the cameras.
The information acquisition system can generate a synchronous signal and control the at least two cameras to synchronously acquire the target information according to the generated synchronous signal, wherein the synchronous signal corresponds to at least one shooting moment, and the at least two cameras can synchronously acquire the target information at each shooting moment according to the synchronous signal. The target information acquired by the camera comprises image information shot by target shooting parameters and audio information acquired at the shooting moment, and the integrity of information acquisition can be ensured by acquiring the image information and the corresponding audio information. The camera is provided with an audio collecting device for acquiring audio information.
Because the at least two cameras receive the synchronization signal, and the synchronization signal can correspond to one, two or more shooting moments, the at least two cameras can be controlled to synchronously execute the shooting action at each shooting moment according to the synchronization signal, and the corresponding audio information can be acquired while the shooting action is executed. For example, the synchronization signal corresponds to 3 shooting times at each of which the camera a, the camera B, and the camera C synchronously perform a shooting action and acquire corresponding audio information when performing the shooting action.
By controlling the at least two cameras to acquire the target information based on the synchronization signals, the at least two cameras can be ensured to have the same time stamp, so that the at least two cameras can acquire the target information synchronously.
And 103, synchronously acquiring the target information respectively acquired by the at least two cameras aiming at each shooting moment.
The information acquisition system can synchronously acquire at least two pieces of target information at each shooting moment, and specifically can be as follows: after the at least two cameras synchronously acquire the target information at a certain shooting time according to the synchronization signal, the at least two target information can be synchronously acquired aiming at the current shooting time, and after the at least two cameras synchronously acquire the target information at the next shooting time according to the synchronization signal, the at least two target information can be continuously and synchronously acquired.
By synchronously acquiring the target information at each shooting moment, the target information corresponding to different cameras can be ensured to be synchronously acquired, so that real-time processing can be realized according to the synchronous target information. After synchronous acquisition of the target information, real-time processing can be performed according to the acquired target information so as to be applied to scenes such as television rebroadcasting, internet live broadcast and the like.
In the implementation process of the invention, the shooting parameters of each camera in the camera matrix are uniformly adjusted to the target shooting parameters, so that the shooting parameter adjusting time can be shortened, the consistency of the shooting parameters of the cameras is kept to the maximum extent, each camera in the camera matrix is controlled to synchronously shoot and acquire audio through the synchronous signals, the synchronism of target information acquisition can be ensured, images with the same shooting effect can be acquired under the condition of frame synchronization, and the synchronous shooting effect and the consistency of the images can be ensured.
In addition, the information acquisition method provided by the embodiment of the invention can shorten the shooting parameter adjustment time, can ensure the shooting continuity to the maximum extent when the environmental state changes, is suitable for live broadcast application scenes, and can provide services for a plurality of application scenes such as panoramic stitching, multi-view free viewing and the like by keeping the consistency of the shooting parameters under the condition of frame synchronization.
In an optional embodiment of the present invention, the adjusting, according to the shooting parameter adjustment signal, the shooting parameters of at least two cameras included in the camera matrix to be target shooting parameters includes:
determining the target shooting parameters based on the environment state and the shooting requirements;
generating the shooting parameter adjusting signal based on the target shooting parameter;
and transmitting the shooting parameter adjusting signals to at least two cameras, and controlling the shooting parameters of the at least two cameras to be adjusted to the target shooting parameters.
When the information acquisition system adjusts the shooting parameters of the at least two cameras according to the shooting parameter adjustment signal, the information acquisition system may first determine target shooting parameters based on the environmental status and the shooting requirements, and after determining the target shooting parameters, may generate a shooting parameter adjustment signal based on the target shooting parameters. And then transmitting the generated shooting parameter adjusting signals to at least two cameras so as to control the cameras to adjust the shooting parameters into the target shooting parameters according to the shooting parameter adjusting signals.
The method specifically comprises the following steps: the information acquisition system determines shooting parameters such as brightness, chroma, hue, focal length, RGB components, shutter speed, gain, white balance and the like according to actual conditions on site, generates shooting parameter adjusting signals and transmits the shooting parameter adjusting signals to each camera in the camera matrix, so that the cameras can adjust the shooting parameters.
Above-mentioned implementation process can confirm the target shooting parameter based on environmental condition and shooting demand, shoots the parameter with the target and sends the camera with the form of shooting parameter adjustment signal to control the camera and shoot parameter adjustment, can shorten shooting parameter adjustment time through automatic adjustment, and keep the uniformity of the shooting parameter of camera, and can adjust shooting parameter according to environmental condition, in order to guarantee the shooting effect.
In an optional embodiment of the present invention, the controlling, according to the synchronization signal, at least two of the cameras to synchronously acquire target information at a shooting time includes:
generating the synchronous signal according to a square wave signal with a preset frequency, wherein the level change time of the square wave signal corresponds to the shooting time of the synchronous signal;
and transmitting the synchronous signals to at least two cameras, controlling each camera to execute shooting action at the level change moment of the square wave signals and collecting the audio information.
Before controlling the camera to acquire the target information at the shooting time according to the synchronization signal, the synchronization signal may be generated first, and specifically, the synchronization signal may be: the method comprises the steps of generating a synchronous signal based on a square wave signal with a preset frequency, wherein the preset frequency is a certain fixed frequency, and the shooting frame rate of the camera is a fixed frame rate, so that the selected square wave signal is the fixed frequency, wherein the duty ratio of the square wave signal is preferably 50%, the duty ratio can also be adjusted according to requirements, and the time interval between any two adjacent shooting moments is equal under the condition that the duty ratio is 50%. The level change time of the square wave signal is the shooting time corresponding to the synchronization signal, i.e. each rising edge and each falling edge of the square wave signal correspond to the shooting time.
After the synchronization signal is generated, the synchronization signal can be transmitted to at least two cameras, so that the cameras in the camera matrix correspond to the same synchronization signal source, the cameras in the camera matrix are guaranteed to have the same time stamp at the same shooting moment, and synchronous locking of the shooting moment is achieved.
After the synchronization signal is sent to the at least two cameras, the at least two cameras may be controlled to perform a shooting action at a shooting time, and audio is collected based on the audio collection device, where the shooting time is a time of a level change of the square wave signal, specifically, at each rising edge and falling edge of the square wave signal, the at least two cameras are controlled to perform the shooting action and collect audio information.
The collected audio information is corresponding audio information before the shooting time, and a specific example is described below as to a relationship between the audio information and the shooting time. As shown in fig. 2, the camera is controlled to perform a shooting action and collect audio information at the rising edge and the falling edge of the square wave signal, which is exemplified by a duty ratio of 50%, and if the audio sampling frequency is 48KHz and the shooting frame rate is 25 frames, the number of audio samples in each group is: and 48000/25 is 1920 pieces. Then the first set of audio associated with the first frame image corresponds to sample points 1 through 1920, the second set of audio associated with the second frame image corresponds to sample points 1921 through 3840, and so on. If the shooting frame rate is 50 frames, the number of audio samples in each group is: and 48000/50 is 960. The first set of audio associated with the first frame image corresponds to the 1 st to 960 th sample points, the second set of audio associated with the second frame image corresponds to the 961 st to 1920 th sample points, and so on.
According to the implementation process, the synchronous signals can be generated based on the square waves with fixed frequency, so that at least two cameras are controlled to execute shooting actions and collect audio information at the level change moment of the square wave signals, target information is synchronously acquired, the synchronous shooting effect can be ensured, and complete image information can be acquired.
In an optional embodiment of the present invention, the synchronously acquiring, for each shooting time, the target information respectively acquired by at least two cameras includes:
synchronously receiving the target information respectively transmitted by at least two cameras aiming at each shooting moment;
performing synchronous clock verification on at least two received target messages;
and under the condition that the synchronous clock passes the verification, determining that the received at least two pieces of target information correspond to the same shooting moment, and encoding and storing the received at least two pieces of target information to a preset position.
When the target information respectively acquired by the at least two cameras is synchronously acquired, the target information respectively transmitted by the at least two cameras can be synchronously received aiming at each shooting moment, after the at least two pieces of target information are received, synchronous clock verification can be carried out on the at least two pieces of target information to determine whether the received at least two pieces of target information correspond to the same shooting moment, and under the condition of successful verification, the at least two pieces of target information correspond to the same shooting moment.
Since time deviation may occur in the image information in the target information during transmission (the time length corresponding to one frame of image changes), after the target information is received, the image information may be calibrated, and the time length corresponding to one frame of image is calibrated to the standard time length. For example, if the time length corresponding to a received frame of image is 39ms, and the standard time length corresponding to a single frame of image is 40ms, the received image may be calibrated, and the time length corresponding to the frame of image may be calibrated to 40 ms.
Under the condition that the synchronous clock passes the verification, at least two pieces of received target information can be respectively subjected to coding operation, then the coded target information is written into a hard disk to be stored to a preset position, and the target information can be compressed by storing after being coded, so that the storage space is saved. The process of performing synchronous clock verification on at least two pieces of target information and performing code storage after verification is passed can be seen in fig. 3.
The implementation process can detect whether the received at least two pieces of target information correspond to the same shooting time or not based on the synchronous clock verification, and code and store the target information under the condition that the at least two pieces of target information correspond to the same shooting time, so that the target information can be synchronously acquired, and meanwhile, the storage space is saved.
In an optional embodiment of the present invention, after performing synchronous clock verification on at least two pieces of received target information, the method further includes: under the condition that the synchronous clock check fails, determining that the received at least two pieces of target information correspond to different shooting moments; and outputting the prompt information of the information asynchronization, and stopping the synchronous receiving of the target information.
After the synchronous clock verification is performed on the at least two pieces of target information, if the synchronous clock verification fails, it is determined that the at least two pieces of target information correspond to different shooting moments, and at this time, a prompt message for prompting that the received at least two pieces of target information are not synchronous can be output, and the synchronous reception of the target information is stopped. Early warning can be realized by outputting the prompt information, so that technicians can conveniently process the prompt information, the target information is stopped from being received when the prompt information is output, and the condition that the verification is not passed can be avoided.
When one piece of asynchronous target information exists in at least two pieces of target information, the synchronous check is that the synchronous check is not passed. For example, after receiving the object information 1, the object information 2, and the object information 3, it may be detected whether the object information 1, the object information 2, and the object information 3 correspond to the same shooting time, and if the object information 1 corresponds to the shooting time 1 and the object information 2 and the object information 3 correspond to the shooting time 2, the verification fails, and at this time, the prompt information may be output and the synchronous reception of the object information may be stopped.
The implementation process can detect whether the received at least two target messages correspond to the same shooting time or not based on the synchronous clock verification, and under the condition that the at least two target messages correspond to different shooting times, the prompt messages are output and the target messages are stopped being received, so that the early warning when the received messages are asynchronous can be realized, and the asynchronous target messages are prevented from being received again.
The above-mentioned overall implementation process of the information acquisition method provided by the embodiment of the present invention is to adjust the shooting parameters of each camera in the camera matrix to the target shooting parameters uniformly, so as to shorten the shooting parameter adjustment time, ensure the shooting continuity to the maximum extent when the environmental status changes, maintain the shooting parameter consistency of the cameras to the maximum extent through uniform adjustment, control each camera in the camera matrix to shoot and acquire audio synchronously through the synchronization signal, ensure the synchronization of the acquisition of the target information, further acquire images with the same shooting effect under the condition of frame synchronization, ensure the synchronization of the shooting effect and the image consistency, and provide services for various application scenes such as panorama splicing, multi-view free viewing, and the like.
In addition, the invention can adjust shooting parameters according to the environment state to ensure the shooting effect, can synchronously acquire target information according to the synchronous signal and carry out coding storage, saves the storage space while realizing synchronous information acquisition, and can also carry out early warning when the information is not synchronously received to ensure the effectiveness of information acquisition.
