s601, identifying whether the person image contains the first identification pattern.

In this embodiment, the first identification pattern is disposed on the outer surface of the helmet, for example, the first identification pattern may be a triangular pattern, a circular pattern, and the like, which is not limited herein. When the image is detected by the helmet, only the first identification pattern can be detected, and the outline, the color and the like of the helmet do not need to be detected, so that the image detection of the helmet is simpler and more accurate. The second identification pattern is disposed on an outer surface of a person garment, such as a work garment unified by a worker, for example, the second identification pattern may be a rectangular pattern, a pentagonal pattern, and the like, which is not limited herein. When the person is detected in the image, only the second identification pattern can be detected, and the contour, the color and the like of the person are not required to be detected, so that the image detection of the person is simpler and more accurate. In identifying whether a person in the personal image wears the helmet, it may be first identified whether the personal image contains the first identification pattern.

S602, if the character image contains the first identification pattern, determining the position information of the helmet in the character image according to the first identification pattern.

In this embodiment, if it is recognized that the person image does not include the first identification pattern, it indicates that the person image does not include the helmet, and thus it is determined that the person in the person image does not wear the helmet. And if the person image is identified to contain the first identification pattern, determining the position information of the helmet according to the first identification pattern. The position information of the helmet is the position information of the helmet in the character image.

In this embodiment, after the person image is recognized to include the first identification pattern, the second identification pattern in the person image is recognized, and the position information of the person in the person image can be determined according to the second identification pattern. The position information of the person is the position information of the person in the person image.

S604, determining whether the person in the person image wears the helmet or not according to the position information of the helmet in the person image and the position information of the person.

In this embodiment, the extracted person image may be an image including only one person. The positional relationship between the image of the person and the position information of the helmet can be determined based on the position information of the helmet and the position information of the person, and it can be determined whether the person wears the helmet or not based on the positional relationship. For example, if the distance between the position of the helmet in the person image and the position of the person in the person image is smaller than a preset distance threshold, it is determined that the helmet is worn by the person in the person image, otherwise, it is determined that the helmet is not worn by the person in the person image.

The first identification pattern on the identification helmet and the second identification pattern on the person garment can reduce the difficulty of image identification, and whether the person in the person image wears the helmet or not can be accurately and quickly identified, so that the identification speed and accuracy are improved.
