Embodiment 1
[0028] This embodiment provides a method for establishing a human face and hand detection model, which can be used to establish a related model for identifying whether the driver has a mobile phone behavior during driving, such as figure 1 shown, including the following steps:
[0029] S11: Label the first face information and first hand information when the user does not answer or call the mobile phone in the sample image, and the second face information and second hand information when the user answers or calls the mobile phone, and generate annotated training In the sample, the first and second face information include face features and face location information respectively, and the first and second hand information include hand features and hand location information. For example, if the user is the driver, the image can be obtained by collecting historical video streams in the cockpit. Generally, the car is equipped with a camera. Since the camera is installed on the fron...
Embodiment 2
[0035] This embodiment provides a method for detecting the behavior of calling and receiving mobile phones, which can be used to identify whether the driver has the behavior of calling and receiving mobile phones during driving, such as figure 2 shown, including the following steps:
[0036] S21: Acquire a target image. For example, for the behavior detection process of the driver in the traffic system, the target image can be obtained by collecting the real-time video stream in the cockpit. Generally, the car is equipped with a camera. Since the camera is installed on the front windshield of the car, through The camera installed in the car collects images of the driver's seat area, which can clearly capture the driver's behavior without the assistance of other electronic devices, and will not affect the driver's normal driving.
[0037] S22: Input the target image into the human face and hand detection model established by the method for establishing a human face and hand d...
Embodiment 3
[0041] This embodiment provides a device for establishing a face and hand detection model, which can be used to establish a related model for identifying whether the driver has a mobile phone behavior during driving, such as image 3 Shown, comprise: labeling module 31, extraction module 32 and training module 33, each module function is as follows:
[0042] Annotation module 31 is used for labeling the first face information and the first hand information when the user does not answer and call the mobile phone in the sample image, and the second face information and the second hand information when the user answers and calls the mobile phone, and generates For the training sample after marking, the first and two face information include face features and face position information respectively, and the first and second hand information include hand features and hand position information. For details, refer to step S11 in embodiment 1. A detailed description.
[0043] The extr...
