Example 2
Based on the foregoing embodiment 1 of the present utility model, embodiment 2 of the present utility model provides a method for implementing a behavior supervision device in supervision of an offence of "people not wearing a helmet" in a video image of a power construction site, specifically including:
in the above application scenario of embodiment 2 of the present utility model, the connection manner between the camera outside the behavior supervision device and the device includes wired connection and wireless connection, and the camera does not need to have a network transmission function, so that the cost brought by the camera is reduced.
Firstly, an RK3399Pro processor sends a video data acquisition request instruction to a camera outside the device, and the camera acquires operation video data by shooting and recording an electric power construction site after receiving the request instruction.
Then, when the external camera is in wired connection with the device, the camera transmits the collected video data to the 4G router through the network port and the network cable; when the camera is in wireless connection with the device, the camera transmits collected video data to the 4G router through the SMA connector and the signal line successively on the basis of providing communication signals for a WIFI antenna outside the device.
And secondly, the 4G router forwards the received video data to the RK3399Pro processor for management, analysis and storage, wherein the number of network ports is equal to the number of the RK3399Pro processors.
Wherein the management actions of the RK3399Pro processor include:
the user manually sets technical parameters, namely video reading frequency, for the RK3399Pro processor, the default video reading frequency is 24 frames/second, and the RK3399Pro processor reads video data according to the video reading frequency set by the user, wherein the video reading frequency is equal in interval of frames, such as: in embodiment 2 of the present utility model, the video reading frequency set by the user is 12 frames/second, and then the RK3399Pro processor needs to fetch 12 frames of image data at regular intervals in 24 frames, that is, fetch one frame of image data every interval, and fetch enough 12 frames of image data within a time span of one second, and then the RK3399Pro processor stores the fetched image data in the internal memory of the RK3399Pro processor.
The analytical behavior of the RK3399Pro processor includes:
the RK3399Pro processor reads the image data stored by it in the management action in its internal memory, transforms the size corresponding to the original definition of all images into a size adapted to the requirements of the RK3399Pro processor, which is set by the RK3399Pro processor according to the computing power of the device, the higher the computing power of the device, the larger the size set by the RK3399Pro processor. Such as: in embodiment 2 of the present utility model, the RK3399Pro processor scales the size of the original image with 1080P resolution from 1920×1080 pixels to 416×416 pixels. In addition, to simplify the scaling process, the RK3399Pro processor further performs compression processing on the scaled image, so that the value range of each pixel in the image is changed from 0 to 255 to 0 to 1, for example: the value of a certain pixel is 50, and the value of the pixel after compression conversion is 51/255=0.2, so that the value of the pixel can be directly obtained without other conversion, and the value of the pixel accounts for 20%.
Further, the RK3399Pro processor performs an equal pixel blocking process on the image after the previous compression process, for example: in this embodiment, the pixels such as the image with 416×416 pixels are divided into the image matrix with 13×13 pixels, and the size of the image matrix after division in embodiment 2 of the present utility model is 13×13 pixels, which is the empirical data, and the apparatus takes the empirical data to have the best recognition effect on the target.
Further, the RK3399Pro processor classifies the image matrix after the previous step of blocking, and specifically includes:
calculating the probability value of each pixel belonging to a certain target class in the image matrix until all the target classes in the image are traversed, namely obtaining a probability value table for each target class;
screening the probability value table according to the threshold value of the target category corresponding to the probability value table to obtain a plurality of probability values aiming at each probability value table, wherein the boundaries of the pixels corresponding to the plurality of probability values form a plurality of screening frames;
the pixels in the screening frames in the image matrix belong to the target class, or else, do not belong to the target class, so that the purpose of classifying each pixel in the image matrix is achieved, after classification is finished, each screening frame is a target, and the target class and the position of each screening frame are output.
Still further, the RK3399Pro processor calculates the distance and direction between the targets according to the specific supervision behaviors, and obtains parameters describing the target relationship: (L, a), wherein the distance l=sqrt ((x 1-x 2)/(2+ (y 1-y 2)/(2)), azimuth a=arctan (|y1-y2|/|x1-x 2|); the RK3399Pro processor matches the calculated parameters of the target relation with the parameters in a preset target relation library, and when the distance and the direction accord with L (min) < L (max), A (min) < A (max), the matching is successful, otherwise, the matching is failed; and the RK3399Pro processor judges whether the video image has illegal behaviors according to the matching result, if so, the RK3399Pro processor forwards the alarm data to the alarm module through the 4G router to alarm, and acquires the geographical position information of the place where the illegal behaviors occur. L (min) and L (max) are respectively the minimum value and the maximum value of the distance between the targets in the target relation library, and A (min) and A (max) are respectively the minimum value and the maximum value of the azimuth between the targets in the target relation library. Specifically:
in the regulation of illegal behaviors that the person does not wear the safety helmet in the video image in embodiment 2 of the utility model, the identification targets are "person", "safety helmet" and "safety helmet-no", wherein "safety helmet-no" indicates that the person does not wear the safety helmet, and is recorded as "safety helmet-no" when the person does not wear the safety helmet in the video image, and is recorded as "safety helmet-no" when the person does wear the safety helmet in the video image.
After the identification is finished, if people, safety helmet-no and safety helmet-x are identified, the fact that no illegal action that the people do not wear the safety helmet exists in the current video image is indicated; if the person, the safety helmet-no and the safety helmet are identified, the fact that the person does not wear the safety helmet is indicated to exist in the current video image, at the moment, the RK3399Pro processor forwards alarm data to the alarm module through the 4G router, the alarm module controls the light-operated alarm unit and/or the sound-controlled alarm unit to alarm when receiving the alarm data, the light-operated alarm unit starts a network relay immediately, and the network relay controls the alarm lamp to flash and alarm through a network cable; the sound control alarm unit starts a digital power amplifier through an AUX interface, and the digital power amplifier starts an electromagnetic loudspeaker to play audio alarm contents through a network cable, such as' please wear a safety helmet-! ".
Therefore, under the environment with poor network conditions, the device can carry out audible and visual alarm reminding on illegal behaviors offline, prompt on-site construction operators to correct in time, and monitor personnel are not required to remotely supervise the correction through telephone or other modes.
Therefore, the device immediately identifies and analyzes the video data after collecting the video data at the operation site, and the original video does not need to be transmitted to a central server for identification and analysis, so that redundant information generated in the network transmission process of the original video is effectively avoided.
Then, the external Beidou antenna of the device provides wireless communication signals required by positioning for the GPS global positioning system or the Beidou satellite navigation system through the SMA connector and the signal line, and the RK3399Pro processor controls the GPS global positioning system or the Beidou satellite navigation system to position the illegal action occurrence place through the RS232 interface so as to acquire geographic position information of the illegal action occurrence place, and then the GPS global positioning system or the Beidou satellite navigation system transmits the acquired geographic position information to the RK3399Pro processor through the RS232 interface.
Finally, the RK3399Pro processor forwards the result data of the video data analysis and the geographical position information of the place where the illegal action occurs to a remote central server for storage through a 4G router, a signal wire and an SMA connector on the basis that a 4G antenna outside the device provides a 4G communication signal, so that a supervisor in a monitoring room where the central server is located can review the result data of the video data analysis and the geographical position information of the place where the illegal action occurs.
Therefore, after the device is identified and analyzed, only a small amount of judgment result data and geographical position information need to be transmitted to the central server, compared with the method of transmitting the original video to the central server for identification and analysis, the device does not need to occupy too large network bandwidth, so that the requirement on network stability is reduced, and the device is not influenced by factors such as field construction operation area fluctuation, unstable field network conditions and the like.
In addition to the functions described above, the RK3399Pro processor is also responsible for carrying out program operations and for signal input/output forwarding. The RK3399Pro processor also comprises a Central Processing Unit (CPU) unit, a nonvolatile memory unit (ROM), a volatile memory unit (RAM), a network interface unit, a Universal Serial Bus (USB) interface unit, a high definition audio-video (HDMI) interface unit, an audio interface unit and a main control board heat dissipation unit. The Central Processing Unit (CPU) is a processor based on an Arm instruction set, so that the device is designed for low power consumption.
In conclusion, the device can identify and analyze the behaviors of operators on the operation site, so that whether the operation behaviors are normal or not is judged, and video data are not required to be transmitted back to a central server for identification and analysis, so that the device is not influenced by factors such as the fluctuation of a field construction operation area and the instability of the field network condition, and therefore, the effective supervision of the behaviors of the operators can be realized under various complex working condition environments.
