Data stored in the data server can be selectively called and checked through the management APP on the background handheld terminal, so that the system is convenient to operate and use.
The invention discloses an information analysis method for exhibition data visualization, which comprises the following steps:
1) each camera of the image acquisition device acquires images in a view field; in the step 1), the image acquired by the camera of the image acquisition device is a video image and/or a picture image, the acquired video image can reflect the change of people stream data in the visual field of the camera more intuitively and vividly, for example, the observer can visually see the change of people flow in the visual field by playing back the video image acquired by the specific camera through the management APP on the handheld terminal. In contrast, the picture image is a static image, which is convenient for data processing.
Of course, it is conceivable that only a video image or a picture image may be acquired by the camera, the picture image may be obtained by acquiring frame data of the video image in a single video image mode, and the people stream change information in the camera view field may also be obtained by playing back the picture image in the single picture image mode.
2) The image acquisition device acquires an obtained image and sends the image to a data server of the background management device for storage; these data are used for retrieval and viewing. In the step 2), the image acquisition device transmits the acquired image to the background management device and stores the image in the field storage module of the image acquisition device, and a backup of the image is reserved in a local storage mode, so that the image is convenient to call and view.
3) A data processing computer of the background management device calls image data from the data server, extracts a portrait in the image data and facial feature data of the portrait, and stores the extracted facial feature data of the portrait in the data server;
in the step, a portrait extraction algorithm and a portrait facial feature data extraction algorithm are executed, which are the prior art and have been applied to various electronic products such as security electronic systems, so that the algorithm is not repeated in the patent. Specifically, the portrait extraction refers to extracting an effective portrait in an image, the portrait is clearly recognizable, fuzzy portraits and portraits with faces not facing a camera are not extracted, the portrait facial feature data extraction refers to performing facial feature recognition on the obtained portrait, similar to the existing face brushing payment principle, facial features of each person are relatively unique, the extracted facial feature data are used for marking specific persons, and the recognition of subsequent persons is based on data comparison of the facial features.
4) The data processing computer compares the face feature data of the face of the person obtained by current extraction with the face feature data of the person stored in the data server in a traversing mode, and calculates the matching degree score obtained by each comparison;
the degree of match score may be a percentage reflecting the similarity of facial feature data, with a greater degree of match score representing more similar facial feature data, whereas a lesser degree of match score representing less similar facial feature data.
5) The data processing computer compares the matching degree score obtained in the step 4) with a preset matching degree threshold value, if the portrait with the matching degree score larger than or equal to the set threshold value is judged to be the portrait which is analyzed and input before, the state parameters of the portrait are stored into a corresponding portrait file in the data server and the exhibition parameters are modified at the same time, if the portrait with the matching degree score smaller than the set threshold value is judged to be the new portrait, the new portrait file is established in the data server and the exhibition parameters are modified at the same time;
the threshold of the matching degree is preset in the system, as described above, when the similarity score is a percentage of the similarity, a suitable percentage is set to measure the similarity of the facial feature data, for example, the threshold of the matching degree is set to 95%, it is considered that when the matching degree score is greater than or equal to 95%, the current portrait is determined as a portrait already existing in the data server, and correspondingly, when the matching degree score is less than 95%, the current portrait is determined as a portrait not existing in the data server.
When the matching degree score is smaller than the set threshold, the portrait is judged as a new portrait, namely, the data server does not have the portrait file of the person, and the file needs to be established. Therefore, when the system is just put into use (for example, the exhibition has just finished the exhibition and the exhibitors have not entered the exhibition occasion), the portrait archive in the data server is empty, the portrait archive is gradually established in the data server from the acquired effective facial feature data of the first effective portrait, and the portrait archive in the data server is gradually increased along with the extension of the system operation time.
Specifically, when the matching degree score is found to be greater than or equal to the threshold value after the facial data features of the next portrait are compared, the number of the portrait files in the data server is unchanged, at the moment, only the parameter data of the portrait file is revised, when the matching degree score is found to be smaller than the threshold value after the facial data features of the next portrait are compared, the number of the portrait files in the data server is increased by one, at the moment, a new portrait file is established, and the parameter data are input.
The state parameters in the step 5) include, but are not limited to, the time when the portrait is acquired and the number of the camera acquiring the portrait, and the exhibition parameters include, but are not limited to, the number of the acquired portraits, the age group distribution of the portraits, the sex ratio, and the flow rate of people.
6) When the portrait is judged to be new in the step 5), the data processing computer executes a gender and age identification algorithm to identify the gender and age of the portrait and records the gender and age of the portrait as parameters into a portrait file in a data server;
the gender and age identification algorithm executed in the step is the prior art, and is already applied to various electronic products such as security electronic systems and mobile phones, so the algorithm is not described in detail in the patent. It should be noted that there is a certain error in the sex and age of the portrait acquired by executing the sex and age identification algorithm, but such an error does not affect the visualization of the exhibition data, and in fact, the current situation of the exhibition site is complex, and the information analysis system and the information analysis method focus on acquiring typical exhibition data to reflect the basic situation of the exhibition, and therefore, do not require extreme accuracy of the acquired information.
7) And at every set updating time interval, the data processing computer calls the analyzed data of the image stored in the data server, and updates the graphical display on the background display module after the data processing.
The update time support setting is set to update the display once every 1 minute, 5 minutes, 10 minutes, or the like, but it is needless to say that the update time interval may be set as needed, but it is not necessary to update the data display too frequently.
In step 7), the data processing computer simultaneously and independently processes the images acquired by the cameras of each image acquisition device and the images acquired by the cameras, and the processed data is pushed to the corresponding image acquisition devices and visually displayed on the field display module of the corresponding image acquisition devices.
Furthermore, the information analysis method also comprises the step of pushing data to the background handheld terminal and carrying out visual display and the step of pushing data to the field handheld terminal and carrying out visual display, and by executing the pushing step, field personnel can acquire the visual information of the exhibition data obtained by the system through the handheld terminal at any time.
Taking the case that two persons move in a certain exhibition area (i.e. in the visual field of one of the cameras of a certain image acquisition device) and then one person enters the exhibition area as an example, the operation method of the information analysis system will be described:
1) the camera shoots video images and picture images of the two persons to serve as image data;
2) the video image and the picture image are sent to a data server in a wireless communication mode to be stored, and are stored in a field storage unit;
3) the data processing computer calls the image data from the data server, executes an algorithm, extracts a portrait in the image data and facial feature data of the portrait, and stores the facial feature data of the portrait obtained by extraction into the data server, wherein two facial feature data of the portrait are obtained in the step;
4) the system just starts to operate, a portrait file does not exist in the data server, so that two portrait facial feature data are stored in the data server and then two portrait files are generated, after the portrait file is generated, parameter information is recorded in the file, the parameters comprise the time for establishing the file, namely the time for the information analysis system to detect the person for the first time, and the serial number of a camera, such as A001, wherein A refers to the serial number of an exhibition area, 001 refers to the 001 camera of the exhibition area, the position of the camera is calibrated in the system, and the exhibition scene data preset in the data server comprises the specific position in the exhibition scene where the calibrated camera serial number is located;
5) because the two portrait files in the step 4) are newly-built files, a gender and age identification algorithm is executed in the step, the gender and the age of the two persons are identified, for example, the male is 26 years old, the gender and the age are taken as parameters to be recorded into the portrait files, and the gender and the age in the portrait files are not changed in the subsequent whole information analysis and visualization process;
after a third person enters a visual field, the image acquired by the camera comprises the three persons, the steps of face recognition and face feature extraction of the three persons are executed again, then face feature data are compared with face feature data in two existing archives to obtain matching degree scores, the matching degree of the third person and the former two persons is known to be low, the system judges that the third person is a new person, a new face archive is established, parameter information of the third person is recorded at the same time, and the recorded parameter data are updated in the archives of the two persons (original data do not disappear) because the former two persons are also analyzed by information;
thus, the steps are continuously carried out;
6) the data processing computer processes data at regular intervals and displays the processed result on the background display module, and the displayed information can be: the total number of the total-obtained effective portrait (corresponding to the number of portrait files established in the system), portrait age group distribution in a chart mode (such as more people in teenagers, more people in old people and the like), sex proportion (such as male A% and female B%), and pedestrian flow (such as more people in each time period); the information is exhibition-level information, namely the visualization condition of data of the whole exhibition is reflected;
the data processing computer simultaneously calculates exhibition data of the position of each image acquisition device and exhibition data of each camera, the data can be consistent with the exhibition level data, the exhibition data of the specific position is visualized, and exhibitors and the like pay more attention to the pedestrian flow condition of the specific position, namely the exhibition area or the specific position (the position of a specific exhibit) of the exhibition area.
