Embodiment Construction
[0033] The present invention will be further described below in conjunction with the specific embodiments in the accompanying drawings.
[0034] refer to Figure 1-3 , a safety helmet wearing detection method, the method comprises:
[0035] Obtain the original image of the construction site, amplify the original image by N times through image transformation to obtain the amplified image, the size of N can be set according to the actual situation, in this embodiment, N is equal to 3;
[0036] Annotate helmet information on the augmented image;
[0037] Input the original image, augmented image and helmet information into the target detection network to learn and perform image feature extraction to obtain face features;
[0038] Obtain the face frame diagram according to the face features;
[0039] Determine the head area according to the face frame, and perform helmet detection in the head area.
[0040] Image transformation includes image brightness transformation and mirr...
