Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
FIG. 1 is a block diagram of an automated target detection platform according to an embodiment of the present invention.
As shown in FIG. 1, an automated target detection platform 10 according to an embodiment of the present invention may include: data set management module 100, model training module 200, model verification module 300, and model publishing module 400.
Wherein, the data set management module 100 is used for creating and managing data sets; the model training module 200 is configured to train a model to be trained according to a data set to generate a first target detection model; the model checking module 300 is configured to perform online checking on the first target detection model to generate a second target detection model; the model publishing module 400 is configured to publish the second object detection model.
According to an embodiment of the present invention, as shown in fig. 2, the automated target detection platform 10 further comprises: the authentication module 500, wherein the authentication module 500 is configured to receive identity information input by a user, authenticate the identity of the user according to the identity information, and open the usage right of the user after the identity of the user is successfully authenticated.
Specifically, when the user uses the automated target detection platform 10, the user first needs to fill in information such as a user name, an account number, a password, and the like to complete account registration, and then enters identity information through the identity verification module 500, where the identity information includes the account number and the password. At this time, the identity authentication module 500 may authenticate the identity of the user according to the input identity information, and if the input account corresponds to the password, it indicates that the user identity authentication is successful, and at this time, the automatic target detection platform 10 may be entered and a home page may be skipped.
Further, after the user successfully logs in the automatic target detection platform 10, the user may perform model training through the automatic target detection platform.
It should be noted that, before the model is trained, the data set management module 100 may create a data set, and correspondingly, according to an embodiment of the present invention, the data set management module 100 is specifically configured to: labeling the target image to obtain a sample image, performing format conversion on the sample image, and compressing the sample image after format conversion to generate the data set.
Specifically, the creation of the data set by the data set management module 100 may include the steps of: (1) designing a label: the number of the targets to be detected can be determined according to actual requirements, the number of the tags corresponds to the types of the targets one by one, wherein the upper limit of the number of the tags is 1000, each type of target at least comprises 20 targets for ensuring the effectiveness of a data set, and in general, the number of the targets contained in each picture does not exceed 100 targets for ensuring the performance of a model; (2) ensure that the sample image meets the format requirements: converting the type of the sample image into jpg, png, bmp, jpeg, limiting the size of the sample image to be within 4M, and limiting the aspect ratio to be 3: 1, wherein the longest edge of the sample image needs to be less than 4096px, and the shortest edge of the sample image needs to be more than 20 px; (3) ensuring that the content of the sample image after format conversion meets the requirement, wherein in order to ensure the validity of the data set, before compressing the sample image after format conversion, the sample image after format conversion needs to be screened to ensure that the content of the sample image after format conversion meets the requirement, wherein the picture of the training set needs to be consistent with the picture environment to be identified in the actual scene, and the pictures of each label need to cover the possibility in the actual scene, such as the change of the photographing angle and the light brightness, the more scenes the training set covers, the stronger the generalization capability of the model; (4) the compression packet format requires: compressing the sample image after format conversion, ensuring that a compression packet is in a zip format, the size of the compression packet is within 5GB, and the compression packet comprises a picture source file and an xml file with label information, wherein the picture name is the same as the name of the xml file containing the label information and is in an inclusion relationship; (5) generating a data set: inputting a data set name, selecting a data set labeling state, adding a compressed package file, and analyzing the data set after the addition is completed, wherein the state after the data set is uploaded is divided into two states of decompression and analysis, and related information of the data set can be displayed in a data list.
According to an embodiment of the present invention, as shown in fig. 3, the automated target detection platform 10 further comprises: and a model creating and querying module 600, wherein the model creating and querying module 600 is configured to create a model to be trained and query model information of the second target detection model.
According to one embodiment of the invention, the model information includes a model version number, a model type, a release status, and a model effect. Wherein, in the model effect, the overall situation description of the model training can be seen, which comprises the following steps: basic conclusion, mAP, F1-score, accuracy, recall. The index of the model effect is based on the training data set to randomly extract partial data, and the partial data does not participate in training and only participates in the evaluation calculation of the model effect. Therefore, when the amount of data is small (for example, the number of pictures is less than 100), the data participating in the evaluation is also small, and the effect of the model evaluation report obtained in this way is only used for reference, and the effect of the model cannot be fully and accurately reflected. That is, the model effect is only used for reference, and if the model effect condition is to be known more fully, the more accurate model effect can be obtained by calling the interface batch test after the model is released as the API.
Specifically, after the data set is created, as shown in FIG. 4, the model to be trained may be created by the model creation and query module 600. The model to be trained can be created by filling in a model name, a contact way, function description information and the like through the model creating and querying module 600, and after the creation of the model to be trained is completed, the created model to be trained can be queried in the model list.
After the model to be trained is created, a data set (an existing data set or a created data set) may be added, and the model to be trained is trained by the model training module 200 according to the data set to generate a first target detection model. When the model is trained, the version which needs to be trained can be selected from the model list according to requirements. The application type selection can select cloud service (corresponding to a general model and a high-precision model) and offline service (corresponding to a general model and a high-performance model), different types correspond to different algorithms, and generally, the high-precision model is better in recognition accuracy but poorer in training speed and recognition speed; the high-performance model is better in training speed and recognition speed, but is poorer in recognition accuracy; the generic model is between the high-precision model and the high-performance model. After training is started, the user can jump to a version list (the model creating and querying module 600) under the corresponding model to check the training state, and the training can also be stopped at any time during the training process.
Further, after the trained model is trained to generate the first target detection model, the model verification module 300 may perform online verification on the first target detection model. Specifically, the model verification module mainly verifies the performance of the trained model, wherein the time for starting the model verification is related to the model, and the model verification can be started successfully after waiting for about 1-5 minutes. In the verification process, corresponding pictures may be added, and a preset number (for example, 10) of pictures may be selected for verification, so as to generate a verified object detection model, that is, a second object detection model. Wherein, the more pictures selected by the verification model, the longer the time is needed.
After verification is completed, the second target detection model may be published through the model publishing module 400, where the second target detection model may be published using cloud services and/or offline services.
In particular, the second target detection model may be deployed in a cloud service, an offline service. As a possible implementation manner, the second target detection model can be packaged into an SDK adapted to the intelligent hardware, and the device-side offline calculation can be performed; as another possible implementation manner, cloud service publishing may be adopted, wherein a service name, an interface address, or other requirements may be added to the cloud service publishing, after the cloud service submits an application, the cloud service jumps to a version list under a corresponding model to check a publishing state, and when the publishing state is "published", the model may be checked for "details of the service" or "offline"; of course, as another possible implementation manner, the cloud service and the offline service may be published simultaneously.
According to an embodiment of the present invention, the data set management module 100 is further specifically configured to: view the data set, and/or modify the name of the data set, and/or supplement the data.
That is, the data set management module 100 may perform operations such as viewing, modifying names, supplementing data, etc., on the uploaded data set in addition to creating a new data set.
It is noted that, based on the automated target detection platform, the underlying architecture diagram of the automated target detection platform according to an embodiment of the present invention can be shown in fig. 5. The underlying architecture of the automatic target detection platform may include an AI engine layer, an AI middleware and an AI framework layer, wherein a data center (data set management module 100) in the AI middleware corresponds to data input, data management and feature construction in the AI engine layer, a model center (model training module 200, model verification module 300, model publishing module 400 and model creating and querying module) in the AI middleware corresponds to automatic modeling, model iteration and model management in the AI engine layer, and an application center in the AI middleware corresponds to model application, application management and application monitoring in the AI engine layer, wherein data in application monitoring may also automatically flow back to data input in the AI engine layer. Correspondingly, the AI framework layer may include: the system comprises a high-dimensional computing framework, a container cloud, an application management tool, distributed computing, high-performance object storage, a data stream management module, distributed storage, an intelligent scheduling engine and automatic resource configuration. That is, the automatic target detection platform can implement the functions of the above embodiments based on the underlying architecture, and in particular, the above embodiments can be referred to, and details thereof are not described herein to avoid redundancy.
