As shown in FIG. 4, it is a flow chart of parameter setting of the driving monitoring method of the present invention. In step S2, the setting module 200 sets a first angle of the camera 24 to photograph a driver's face, and sets a second angle of the camera 24 to photograph the steering wheel 3. In step S4, the setting module 200 sets a first threshold to determine whether the driver is in an awake state. In step S6, the setting module 200 sets a division basis to divide the steering wheel area into a plurality of parts. In the preferred embodiment, the division is based on dividing the steering wheel area into four parts of upper left, lower left, upper right, and lower right according to two mutually perpendicular axes passing through the center of the steering wheel 3 (refer to FIG. 3). Steering wheel 3 schematic). In step S8, the setting module 200 sets the standard position of the left and right hands of the driver in the direction of the steering wheel area to determine whether the driving is reasonable or the like. In the preferred embodiment, the standard position of the left and right hands of the driver in the steering wheel area is that the left hand is in the upper left position and the right hand is in the lower right position, or the left hand is in the lower left position and the right hand is in the upper right position. In step S10, the setting module 200 sets a time interval to check whether the driver adjusts to a reasonable driving. In other embodiments, the division of the steering wheel area and the standard position of the hands in the steering wheel area can be adjusted according to user needs or personal habits. 098141156 Form No. A0101 Page 11 / 28 pages 0982070615-0 201119897 , for example, the steering wheel area can be divided into nine Part and so on. [0049] As shown in FIG. 5, it is a flowchart of the first embodiment of the driving monitoring method of the present invention. First, in step S12, the start button 26 sends a first command to the control module 202 after being pressed. [0050] Step S14, the control module 202 receives the first command and controls the camera 24 to move to the first angle and starts shooting the face of the driver. [0051] Step S16, the recognition module 204 acquires the captured facial image and recognizes the facial region in the facial image. [0052] Step S18, the recognition module 204 calculates an eye region from the recognized face region, and calculates a ratio between the height and the length of the eye region. [0053] Step S20, the determining module 206 determines whether the ratio is greater than a first threshold. If the ratio is greater than the first threshold, indicating that the driver is in the awake state, the flow returns to step S14. [0054] If the ratio is less than or equal to the first threshold, in step S22, the determining module 206 determines that the driver is in a non-awake state. [0055] Step S24, the early warning module 208 issues an early warning to prompt the driver to pay attention. The early warning includes playing the pre-recorded voice by using the speaker 28, for example, “Please drive carefully, pay attention to safety” and other voice prompts. The pre-alarm module 208 can further cut off the throttle 4 to cause the car 1 to slow down and stop. The user can set the function of the early warning module 208 according to individual requirements, for example, only select the voice prompt, only cut off the throttle 4, or the above two types of 098141156 form number A0101 page 12 / 28 pages 0982070615-0 201119897 combination. [0056] As shown in Fig. 6, a flow chart of a second embodiment of the driving monitoring method of the present invention. The flowchart of this second embodiment is based on steps S12 to S22 in the flowchart of the first embodiment shown in Fig. 5. [0057] First, the determination module 2〇6 described in the 'step S30' sends a second command to the control module 2〇2 after determining that the driver is in the non-awake state. [058] In step S32, the control module 2〇2 controls the first image of the position where the camera head 24 is moved to the second angle shooting steering wheel 3 according to the second command. [〇〇59] Step S34, the recognition module 204 acquires the first image, and identifies a steering wheel area and a hand area in the first image. [〇〇6〇] In step S36, the recognition module 204 divides the identified steering wheel area according to the division basis, and determines the position of the steering wheel area where the hand area is located. In step S38, the determination module 206 determines whether the determined position of the steering wheel area occupied by the hand area conforms to the set standard position, thereby judging whether the driver is currently driving reasonably. [0062] If the determined position of the steering wheel area occupied by the hand area conforms to the set standard position, it can be determined that the driver is currently driving reasonably and the flow ends. (10) 63] If the determined position of the steering wheel area occupied by the hand region conforms to the set standard position, the determining module 2〇6 determines that the driver is not driving reasonably in step S4. [0064] 098141156 Step S42, the early warning module 208 issues an early warning to prompt the driver to note the form number A0101, page 3/28 pages 0992070615-0 201119897, the warning includes playing the pre-recorded with the speaker 28. The alert module 208' described in the voice can further cut off the throttle 4 to cause the car 1 to slow down and stop. The user can set the function of the early warning module 208 according to individual requirements.

The flowchart of this second embodiment is based on steps S30 to S40 in the flowchart of the second embodiment shown in Fig. 6. [0069] [0069] Step S50' When the driver is determined not to drive reasonably, the timer 209 initiates timing, and the alert module 208 also issues a voice alert. In step S52, the control module 202 captures the second image of the position of the steering wheel 3 at the second angle after the time interval is reached. In step S54, the recognition module 204 acquires the second image, and identifies a steering wheel area and a hand area in the second image. In step S56, the identification module 204 divides the identified steering wheel area according to the division basis, and determines the location of the steering wheel area where the hand area is located.
