At present, most cameras need to be connected with a network when aging, then a computer is used for searching and adding equipment, and an aging command is issued, so that the process is very complicated. And some cameras are inconvenient to connect with a network when aging, such as wireless cameras, a router network environment needs to be built by workers, then the cameras are subjected to wireless connection and other operations, so that the cameras are very dependent on field personnel, and a large amount of time is consumed. In the prior art, the established special audio sound waves are played through the mobile phone, the camera receives the special audio sound waves and analyzes the special audio sound waves to obtain an aging command, and then the camera can perform corresponding aging operation. The operation personnel only need play audio sound wave with the cell-phone just can make the camera age in batches. However, when the scheme is adopted for aging, the camera must be connected with the microphone, and due to the existence of echo, if the volume of the mobile phone is too large or the mobile phone is too close to the microphone, the camera cannot normally recognize audio sound waves. Therefore, the volume of the speaker of the mobile phone and the distance between the mobile phone and the microphone need to be tested in advance to achieve the best effect. In addition, the aging environment is relatively quiet, otherwise, the camera may not normally receive and recognize the audio sound waves played by the mobile phone, and thus the aging cannot be completed.
Based on the method, the system, the equipment and the storage medium for aging the camera, the network connection is not needed during aging, the operation is simple, and the rapid aging of the camera can be realized.
Fig. 1 is a schematic structural diagram of a camera aging system according to an embodiment of the present invention. As shown in fig. 1, the system includes a computer 100, a playback device 200, and a video camera 300. The computer 100 is communicatively connected to the playback device 200, and the playback device 200 is communicatively connected to the video camera 300.
The computer 100 is configured to encode the aging command to obtain digital data, convert the digital data into an audio file by using a first preset algorithm, and send the audio file to the playing device 200;
the playing device 200 is used for playing audio sound waves according to the audio files;
the camera 300 is configured to receive the audio sound waves played by the playing device 200, identify the audio sound waves, and process the audio sound waves by using a second preset algorithm to obtain processed digital data; the aging module is also used for decoding the processed digital data to obtain a decoded aging command and aging according to the decoded aging command.
In some embodiments, the computer 100 may also adopt other devices with data encoding and data processing functions, such as a notebook computer, a palm computer, and the like.
In some embodiments, the playback device 200 may be a mobile phone, a stereo, or other devices with audio playback functions.
The embodiment encodes the aging command through the computer 100 to obtain digital data. There are various encoding methods, such as reed solomon encoding (RS encoding), to obtain non-binary digital data, so that the audio sound waves played by the playing device 200 are not too complicated, the recognition rate of the audio sound waves by the camera 300 is increased, and thus the fast and correct aging of the camera 300 is realized. The computer 100 converts the non-binary digital data into an audio file by using a first preset algorithm, and transmits the audio file to the playback device 200 through wired or wireless communication. The playback device 200 plays back audio sound waves according to the audio file. The camera 300 receives the audio sound waves played by the playing device 200, recognizes the audio sound waves, processes the audio sound waves by using a second preset algorithm to obtain processed non-binary digital data, decodes the non-binary digital data to obtain a decoded aging command, and ages the camera 300 according to the decoded aging command. The decoding scheme corresponds to the encoding scheme, such as reed-solomon decoding (RS decoding).
In some embodiments, the first preset algorithm is fourier transform, which can convert a time domain signal into a frequency domain signal, so that after the audio file is sent to the playback device 200, the playback device 200 can analyze the audio file, and then play the audio sound wave. The second preset algorithm is inverse Fourier transformation, and the inverse Fourier transformation can transform the frequency domain signal into the original time domain signal, so that the decoding is convenient. It can be understood that the first preset algorithm and the second preset algorithm need to adopt opposite algorithms to realize the relative conversion of data.
In some embodiments, since data may be lost during transmission, in order to ensure that the finally obtained aging command is correct, the camera 300 is further configured to check the processed digital data to determine whether the digital data is lost; if so, the camera 300 receives the audio sound wave played by the playing device 200 again, identifies the audio sound wave received again, processes the audio sound wave received again by using a second preset algorithm, obtains digital data again, and combines the obtained plurality of digital data until correct digital data is obtained, so that it cannot be ensured that the aging command obtained after decoding the digital data is correct.
Other specific work flows of the camera aging system are described in detail in conjunction with the camera aging method described below.
Fig. 2 is a schematic flow chart of a camera aging method according to an embodiment of the present invention. As shown in fig. 2, the method comprises the steps of:
s100, coding the aging command to obtain digital data;
s200, converting the digital data into an audio file by using a first preset algorithm;
s300, sending the audio file to a playing device;
s400, playing audio sound waves by the playing equipment according to the audio file;
s500, receiving audio sound waves played by playing equipment by a camera;
s600, identifying audio sound waves, and processing the audio sound waves by using a second preset algorithm to obtain processed digital data;
s700, decoding the processed digital data to obtain a decoded aging command;
and S800, aging the camera according to the decoded aging command.
The above steps S100 to S300 are executed by the computer 100, step S400 is executed by the playback device 200, and steps S500 to S800 are executed by the video camera 300. The following describes each step in detail:
and S100, coding the aging command to obtain digital data. The computer generates aging commands for aging the camera by programming or other methods, and encodes the aging commands to obtain digital data. The encoding mode is various, such as reed-solomon encoding (RS encoding), so as to obtain non-binary digital data, so that the audio sound waves played by the playing device are not too complex, the recognition rate of the camera to the audio sound waves is improved, and the rapid and correct aging of the camera is further realized.
S200, converting the digital data into an audio file by using a first preset algorithm. The computer converts the non-binary digital data into an audio file using a first predetermined algorithm. In some embodiments, the first predetermined algorithm is a fourier transform. Because the non-binary digital data can be regarded as discrete time domain signals, the discrete time domain signals can be converted into frequency domain signals through Fourier change, the audio file can be conveniently sent to the playing device, then the playing device analyzes the audio file, and then audio sound waves are played.
And S300, sending the audio file to the playing equipment. The computer sends the audio file to the playing device through wired or wireless (e.g., WIFI or bluetooth) communication. In some embodiments, the playing device may be a mobile phone, a stereo, or other device with an audio playing function.
S400, the playing device plays the audio sound waves according to the audio file. The playing device analyzes the audio file and then plays the audio sound wave.
S500, the camera receives the audio sound waves played by the playing equipment. The camera automatically collects the audio sound waves played by the playing device, and the collection mode can be a microphone, a sound pickup device and the like.
S600, identifying audio sound waves, and processing the audio sound waves by using a second preset algorithm to obtain processed digital data. The camera recognizes the audio sound wave, and processes the audio sound wave by using a second preset algorithm to obtain the non-binary digital data in step S100. In some embodiments, the second predetermined algorithm is an inverse fourier transform, which can transform the frequency domain signal into the original discrete time domain signal, thereby facilitating decoding.
S700, decoding the processed digital data to obtain a decoded aging command. The camera decodes the non-binary digital data in a manner corresponding to the encoding, e.g., reed solomon decoding (RS decoding), to obtain the aging command in step S100.
And S800, aging the camera according to the decoded aging command. The camera ages according to the decoded aging command.
In some embodiments, as shown in fig. 3, after step S600, the method further includes:
s610, checking the processed digital data;
s620, judging whether the digital data is lost or not; if yes, executing step S630, otherwise executing step S700;
s630, the camera receives the audio sound waves played by the playing equipment again;
s640, identifying the re-received audio sound waves, and processing the re-received audio sound waves by using a second preset algorithm to obtain digital data again;
and S650, combining the obtained plurality of digital data until correct digital data are obtained.
In some embodiments, since data may be lost during transmission, in order to ensure that the finally obtained aging command is correct, the camera needs to check the digital data after obtaining the digital data to determine whether the digital data is lost. And if so, the camera receives the audio sound wave played by the playing equipment again, identifies the audio sound wave received again, processes the audio sound wave received again by using a second preset algorithm, and obtains digital data again. And merging the obtained plurality of digital data until correct digital data are obtained, so that the aging command obtained after decoding the digital data can not be guaranteed to be correct.
The following describes the camera aging method flow of the present invention in a specific embodiment with reference to fig. 1 to 3. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting.
And the camera carries out RS coding on the aging command to obtain digital data. The digital data is converted to an audio file using a fourier transform. Assuming that the obtained digital data is 3123, the sine wave of 1500HZ corresponds to the number 1, the sine wave of 1600HZ corresponds to the number 2, and the sine wave of 1700HZ corresponds to the number 3, the audio file is a sine wave signal composed of four segments of the sine wave of 1700HZ, the sine wave of 1500HZ, the sine wave of 1600HZ, and the sine wave of 1700 HZ. And the computer sends the audio file to the playing equipment, and the playing equipment plays the corresponding audio sound wave according to the audio file. The camera receives audio sound waves played by the playing device, identifies four sections of sine wave frequencies of 1700HZ, 1500HZ, 1600HZ and 1700HZ, and processes the four sections of sine wave frequencies by utilizing inverse Fourier transform to obtain digital data 3123. And RS decoding the digital data 3123 to obtain a decoded aging command, and executing the decoded aging command to finish aging. In order to ensure that the aging command obtained after the camera decodes the digital data is correct, the camera also checks the digital data, if the digital data is lost, for example, the digital data is 32 or 313, the data is judged to be lost, the camera receives the audio sound wave played by the playing device again, identifies the audio sound wave received again, and processes the audio sound wave received again by using a second preset algorithm to obtain the digital data again. The resulting plurality of digital data are combined until the correct digital data 3123 is obtained. It can be understood that if a plurality of digital data acquired by the camera are lost, a problem may occur in the computer and/or the playback device, and at this time, steps S100 to 300 and/or S400 need to be executed again.
