Embodiment 1

[0051] Such as figure 1 As shown, the present invention provides a kind of real-time head classification detection method based on MobileNetV3, comprises the steps:

[0052] S1. Select a training data set and classify and mark the selected training data set; the training data set includes a mask face data set, a human face data set and a head data set;

[0053] S2. Perform enhanced processing on the image data of the labeled training data set;

[0054] S3. Generate a priori box for each category according to different categories of the training data set;

[0055] S4. Build a model based on MobileNetV3, and then train the model through the training data set;

[0056] S5. Apply the trained model on the large screen, reason the real-time head image captured by the large screen camera, and obtain the classification and detection results.

Embodiment 2

[0058] Such as figure 2 As shown, the present invention provides a kind of real-time head classification detection method based on MobileNetV3, comprises the steps:

[0059] S1. Select a training data set and classify and mark the selected training data set; the training data set includes a mask face data set, a face data set and a head data set; the specific steps are as follows:

[0060] S11. select the training data set; select the mask face data set of the MAFA type, the face data set of the Widerface type and the head data set of the SCUT-HEADv1.0 type;

[0061] S12. Mark the selected training data set, mark the mask face data set of MAFA type as maskface, mark the face data set of Widerface type as face, and mark the head data set of SCUT-HEADv1.0 type as head ; The original MAFA only marked part of the face of the mask, the original Widerface only marked the face, although the original SCUT-HEADv1.0 marked all the heads that appeared, but the labels are the same, with...

Abstract

The present invention provides a kind of real-time human head classification detection method based on MobileNetV3, comprises the following steps: S1. select training data set and classify and mark the selected training data set; Described training data set comprises mask human face data set, human face data S2. Enhance the image data of the labeled training data set; S3. Generate a priori frame for each category according to different categories of the training data set; S4. Build a model based on MobileNetV3, and then pass the training data set Train the model; S5. Apply the trained model on the large screen, reason the real-time head image captured by the large screen camera, and obtain the classification detection result. The invention realizes fast and accurate classification and detection of human heads, and at the same time provides key information points of human faces, and the classification and detection results provide data basis for subsequent processing.

Description

technical field [0001] The invention belongs to the technical field of face recognition, and in particular relates to a real-time head classification and detection method based on MobileNetV3. Background technique [0002] MobileNetV3, a small and efficient network structure proposed by Google for mobile or embedded device applications. [0003] FPN, short for Feature Pyramid Net, feature pyramid network. [0004] SSH, the abbreviation of Single Stage Headless Face Detector, single-step face recognition. [0005] At present, the accuracy and speed of face recognition technology can meet the requirements of the application, and the tracking and statistics products based on face recognition have been implemented. However, due to the impact of the epidemic, the following problems have emerged: [0006] (1) Wearing a mask makes the tracking statistics based on face recognition wrong; [0007] (2) The statistics based on head detection generally only count the flow of people, ...
