In particular, the execution subject may also be other computer devices.
Example one
Referring to fig. 1, a flowchart of an identification method for violent sorting according to an embodiment of the present application is shown, where the method includes steps S101 to S104, where:
s101: acquiring video information corresponding to each article in a plurality of article sorting processes; the video information corresponding to each article comprises a plurality of video images;
s102: sequentially inputting a plurality of video images corresponding to each article into a pre-trained violent sorting identification model, and determining violent sorting identification results corresponding to each article;
s103: in the case that the violent sorting identification result of any article is violent sorting, determining the residence time of the article in the air based on the video information of the article;
s104: and determining a final violent sorting identification result of the article based on the residence time.
The following describes each of the above-mentioned steps S101 to S104 in detail.
Firstly, the method comprises the following steps: in S101, in the article sorting process, the following manner may be adopted to obtain the video information collected in the article sorting process:
acquiring original video information in a sorting process of a plurality of articles; and sequentially identifying the articles of each frame of image in the original video information, and intercepting the video information corresponding to each article in the sorting process from the original video information based on the article identification result.
For example, a monitoring camera is usually installed at some express company or some express delivery point, on one hand, the monitoring camera is used for ensuring that express is not stolen, and once a loss event occurs, some video clues can be provided; on the other hand, the monitoring camera is also used for monitoring whether the courier has the behavior of violent sorting in the sorting process. For example, the surveillance video may be directly used as the original video information.
The video information collected in the article sorting process is intercepted from the whole monitoring video information to obtain a plurality of frame images; for example: detecting whether the monitoring video information corresponds to the same object in real time in the process of acquiring the video information; and when detecting that the monitoring video information corresponds to different articles, intercepting a preset number of multi-frame images before and/or after the images as video information according to the detected images corresponding to the different articles.
In addition, in another embodiment, for example, the video information corresponding to each article in the sorting process may be intercepted from the original video information in the following manner:
intercepting original videos corresponding to the articles in the sorting process from the original video information; and carrying out interval sampling on video images in the original videos corresponding to the objects respectively, and obtaining video information corresponding to the objects respectively based on a plurality of video images obtained by the interval sampling.
In this, the frequency of interval sampling can be set according to actual need, and then reduces the image processing volume of model, promotes detection efficiency.
After the video information is obtained, sequentially inputting each frame of image into a pre-trained first recognition model according to the sequence of the time stamp of each frame of image in the video information, and determining the position information of the article in each frame of image;
the intercepting the video information respectively corresponding to each article in the sorting process from the video information based on the article identification result comprises the following steps:
determining images respectively corresponding to the articles in the sorting process based on the position information of the articles in the images of each frame;
for each article, video information corresponding to the article is generated based on the image corresponding to the article when the article is sorted.
The video information is intercepted from the video information; for example: in the process of acquiring the video information, synchronously and sequentially inputting each frame of image in the video information into a violence sorting identification model, and detecting whether the violence sorting video information exists in the video information in real time; and when the violent sorting video information exists in the video information, intercepting a preset number of video images before and/or after the image as the violent sorting video information according to the image when the result is detected.
For example, an article corresponds to a piece of video information, and the corresponding state of the article is determined based on the position information of the article in each frame of the image, for example: when the article is positioned in a human hand, the article is considered to be at the beginning of a section of video information; when the item is located on the ground, the item is considered to be at the end of a segment of video information. Based on the state corresponding to the article, the image corresponding to each article is determined when each article is sorted, and the video information corresponding to the article is generated.
II, secondly: in S102, the video information is input to a violent sorting recognition model trained in advance, and a violent sorting recognition result corresponding to the video information is determined.
Wherein the violence sorting recognition model is trained in the following way:
acquiring a plurality of sample videos and label information whether to violently sort the articles or not corresponding to each sample video; each sample video comprises a plurality of frames of sample images;
inputting the sample video into a behavior recognition model aiming at each sample video to obtain a violence sorting recognition result corresponding to the sample video;
training the behavior recognition model based on the violence sorting recognition result corresponding to the sample video and the label information to obtain a violence sorting recognition model.
Illustratively, based on a plurality of sample videos obtained in advance, label information whether to violently sort the articles or not, namely a violent sorting sample video and a non-violent sorting sample video, is determined for each sample video.
Wherein each sample video comprises a plurality of frames of sample images.
For example, a plurality of sample videos obtained in advance and label information whether to violently sort the articles or not corresponding to the sample videos are input into the behavior recognition model, and a violence sorting recognition result corresponding to the sample videos is obtained.
Wherein the behavior recognition model comprises one or more of the following:
any one of a Recurrent Neural Network (RNN), a long-short Term Memory (LSTM), and a Gated Recurrent Unit (GRU).
Illustratively, based on a plurality of sample videos obtained in advance, the relative spatiotemporal features of the three-dimensional posture of the human body of each frame of sample image in the violent sample video and the non-violent sample video are respectively extracted, for example: joint pair distance characteristic, joint-to-bone distance characteristic, joint-to-plane distance characteristic, bone pair included angle characteristic, bone-to-plane included angle characteristic, plane-to-plane included angle characteristic, joint rotation characteristic and the like.
And obtaining a violence sorting identification result corresponding to the sample video by using the relative time-space characteristics of the human body three-dimensional posture of each frame of sample image in the violent sample video and the non-violent sample video in the plurality of sample videos.
Training the behavior recognition model based on the obtained violence sorting recognition result corresponding to the sample video and the label information corresponding to the sample video to obtain a violence sorting recognition model for the subsequent recognition process of the video information.
Thirdly, the method comprises the following steps: in step S103, if the result of the violent sorting identification of any article is violent sorting, the retention time of the article in the air is determined based on the video information of the article.
For example, if it is determined in step S102 that the result of the violent sorting identification of the video information is violent sorting, the multi-frame images included in the violent sorting video information in the video information are sorted.
Sequentially inputting each frame of image in the video information into a pre-trained second recognition model, and acquiring article and human hand recognition results corresponding to each frame of image in the video information;
determining a first target image when the human hand is separated from the article and a second target image when the article falls to the ground from each frame image in the video information based on the article and the human hand recognition result corresponding to each frame image;
determining the retention time based on timestamps of the first target image and the second target image.
And obtaining the retention time of the article based on the first target image when the human hand is separated from the article, the second target image when the article falls to the ground and the timestamps corresponding to the first target image and the second target image respectively.
For example, the first recognition model and the second recognition model may be the same recognition model, that is, in a case that the result of the violent sorting recognition of the video information is violent sorting, the first target image when the person is separated from the article, the second target image when the article falls to the ground, and the timestamps corresponding to the first target image and the second target image, respectively, may be determined directly based on the result of the recognition of the first model, and the residence time of the article in the air in the video information may be determined based on the timestamps corresponding to the first target image and the second target image, respectively.
Fourthly, the method comprises the following steps: in the above S104, the final violent sorting recognition result of the video information is determined based on the retention time obtained in the step S103.
Wherein the residence time is compared to a preset residence time threshold.
For example, a sorting residence time threshold value may be determined according to actual conditions, and the residence time may be compared with the residence time threshold value.
When the retention time is larger than the retention time threshold, determining that the violent sorting identification result of the video information is violent sorting;
and when the retention time is less than or equal to the retention time threshold, determining that the violent sorting identification result of the video information is non-violent sorting.
For example, when the staying time of an article away from a human hand to the article landing is relatively long, the trajectory of the article during the sorting process may be considered to be not in accordance with preset requirements, such as: the article may be thrown relatively high or relatively far away, for example, in a hard sort.
For example, after the article is determined to have violent sorting, sorting video information of the article during sorting can be stored, and persons responsible for the article can be tracked, so that the aim of reducing violent sorting behaviors is fulfilled.
After video information corresponding to each article in the process of sorting the articles is acquired, a plurality of video images corresponding to each article are sequentially input into a pre-trained violent sorting identification model, and violent sorting identification results corresponding to each article are determined; and then determining the residence time of any article in the air based on the video information of the article in the case that the violent sorting identification result of the article is violent sorting, and determining the final violent sorting identification result of the article based on the residence time. In the process, the video information of the reserved sorting is firstly identified through the violent sorting identification model, and then the final violent sorting identification result is determined based on the retention time of the articles in the air, so that the accuracy of identifying violent sorting behaviors is greatly improved.
