Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same numerals.

Referring to FIG. 1 , it is the main flow of an embodiment of the method for controlling a driving recorder by gestures of the present invention, and as shown in FIG. 2 , this embodiment is implemented by a system 100 for controlling a driving recorder by gestures applied to automobiles. The system mainly includes a driving recorder 1, a central processing device 2 and a camera 3 arranged on the car; the driving recorder 1 has a lens module 10, which is mainly used to record images inside and outside the car, and the Driving recorder 1 combines functions such as video recording, audio recording, screen segmentation (such as displaying multiple groups of images taken by multiple camera lenses installed inside and outside the car), alarm, tire pressure, network transmission and supporting GPS, making the driving recorder 1 It can ensure driving safety and provide reliable post-analysis images. And the driving recording device 1 usually has a built-in GPS (Global Satellite Positioning) module 11, which can know the current time from the received global satellite signal, so the recorded image also includes the current time of recording. And because the memory space for recording images in the driving recording device 1 is limited, the images recorded previously will be overwritten by the images recorded later, that is, the driving recording device 1 will only retain the latest recorded images.

The central processing device 2 is an electronic device with image processing and computing capabilities (such as a vehicle-mounted computer or a computer host), which is electrically connected to the driving recorder 1, and the central processing device 2 can perform image recognition and control according to the recognition results. The driving recorder 1 is in operation; for example, at least one first gesture and a corresponding lock gear command are stored in the central processing device 2, and the gear locking command can control the driving recorder 1 to record an image file Save it.

The video camera 3 is electrically connected to the central processing unit 2 and is arranged at an appropriate position in the car, and as shown in step S1 of FIG. sent to the central processing unit 2. It is worth mentioning that the camera 3 can be, but not limited to, a camera installed in a driver monitoring system (DMS) installed on a car. The driver monitoring system has been used in cars for many years. , which can detect and monitor the driver's mental state by detecting the steering wheel's turning and driving trajectory and/or detecting the driver's gestures (such as eye closure, blinking, gaze direction, yawning and head movement, etc.) Issue warnings or early warnings in a timely manner. And in this embodiment, the driving recorder 1 and the central processing device 2 can also be integrated with the driver monitoring system, or the driving recorder 1 and the central processing device 2 can be integrated together and use the driving or the image captured by the camera of the monitoring system (ie, the camera 3).

Next, as shown in step S2 of Figure 1, the central processing unit 2 recognizes the image transmitted by the camera 3, and judges whether the first gesture appears in a nearby area of the steering wheel in the image, such as but not limited to fast (for example, within 1 second) Make a fist twice (it can also be to maintain a fixed gesture, such as comparing a specific gesture, etc.), if it is determined that the first gesture appears in the vicinity of the steering wheel, then find out the lock corresponding to the first gesture. Then, as shown in step S3 of Figure 2, when the driving recorder 1 receives the lock command, it will save the currently recorded image file in another image In a specific folder that cannot be overwritten, the locked image file will not be overwritten by the image recorded later. For example, assuming that the driving recording device 1 is set to save the image recorded every minute as an image file with a unit of 1 minute (not limited to this, the setting can be changed), if the driving recording device 1 is at 4:38 p.m. When the gear lock instruction is received in minutes and 25 seconds, the driving recording device 1 will store the images of the interior and exterior of the car recorded from 4:38:01 to 4:38:60 in another specific folder that cannot be overwritten by the images . In addition, if the driving recorder 1 can record images in seconds, when the driving recorder 1 receives the gear lock command at a certain point in time, it can also take a period of time before the time point and a period of time after the time point. Time (for example, 15 seconds before and 5 seconds after the time point, or 15 seconds before and after each time) is recorded as a locked file and stored in a specific folder that cannot be overwritten by the image.

In this way, when the driver needs to make an emergency video recording while driving, he only needs to make the first gesture in the vicinity of the steering wheel without manually looking for and operating the lock button on the driving recorder 1 . Lock the file being recorded and save it separately to ensure that the video file at the critical moment will not be overwritten (overwritten) by the image recorded later.

Or, in another implementation, when the drive recorder 1 receives the lock file command and activates the file lock function, and stores the currently recorded image file in a specific folder that cannot be covered by the image, the central processing device 2 also According to the image recorded by the driving recorder 1 or a GPS position information of the vehicle provided by the global satellite positioning (GPS) module 11, when it is judged that the vehicle is in a stopped state, the central processing unit 2 will force the driving recorder 1 to A radio unit 12 activates the recording function (to prevent the driver from turning off the recording function in the setting), and the central processing device 2 records the image content and sound content according to the driving recorder 1 and/or the built-in recording function of the driving recorder 1 A gravity sensing signal detected by a gravity sensing unit 13 of a gravity sensing unit 13 judges that when at least two of the following four situations occur, an auxiliary alarm function is activated: (1), the central processing unit 2 recognizes the driving The image content recorded by the recorder 1 determines that someone continues to approach the vehicle and the distance from the vehicle is less than a preset distance (for example, less than 1 meter) or approaches and leaves the shooting range of the driving recorder 1 along the body of the vehicle (for example, (2) the central processing device 2 judges that someone has an offensive object (such as a stick/stick/gun) by identifying the image content recorded by the driving recorder 1 etc.); (3), the central processing unit 2 recognizes the image content recorded by the driving recorder 1 or according to the built-in gravity sensing unit 13 of the driving recorder 1 (such as a gravity sensor, G-sensor ) from the gravity sensing signal to determine that the vehicle is vibrating abnormally (such as someone kicking/pushing the vehicle to cause the vehicle to shake); (4), the central processing device 2 recognizes the sound recorded by the driving recorder 1 Content, determine that the volume of the sound content recorded by the driving recorder 1 is related to one or some keywords and attack or violence.

Wherein, the auxiliary alarm function means that the central processing device 2 will control the driving recorder 1 to snap at least one photo in front of the car, and then the central processing device 2 will send a distress message to a rescue terminal through a wireless communication device 4 Electronic device 5, the distress message includes the at least one front-of-the-car photo, the current location information, the preset distress content including a mobile phone number, and/or the driving related to at least two conditions for activating the auxiliary alarm function Related audio and video content recorded by recorder 1. Wherein, the wireless communication device 4 can be, but not limited to, a mobile (network) communication module installed in a car and supports the Internet of Vehicles, or a mobile (network) communication module integrated in the central processing unit 2 Group. And the rescue terminal electronic device 5 can be a cloud server. After receiving the distress message, the cloud server judges that the driver of the vehicle is facing the risk of violence according to the content of the distress message, and then directly assists in notifying the nearest police station or police station. Otherwise (for example, when the cloud server cannot determine whether the driver of the vehicle is facing a risk of violence based on the content of the distress message), the cloud server will contact the driver of the vehicle through the mobile phone number included in the distress message. The driver who is connected to the vehicle will assist in reporting to the nearest police station or police station.

In addition, the rescue terminal electronic device 5 can also be a computer device located at the police terminal, and the police terminal judges whether to immediately carry out rescue or perform relevant confirmation actions (such as contacting the driver of the vehicle).

In addition, the central processing device 2 also stores a second gesture and its corresponding lock gear and help command, and in the above step S2, when the central processing device 2 recognizes the direction of the steering wheel in the image transmitted by the camera 3 When a gesture occurs in the nearby area, and the gesture is the second gesture, such as but not limited to making a fist three times quickly (for example, within 1 second) (or maintain a fixed gesture, such as making a specific gesture, etc.) , and when it is judged that the second gesture corresponds to the lock gear and the help command, the central processing device 2 sends the lock gear command and a request for providing location information to the driving recorder 1, then in step S3, the driving record Device 1 retains the currently recorded image file according to the lock file command, and also obtains a current GPS position information of the car through the global satellite positioning (GPS) module 11 according to the request for providing position information, and returns the GPS position information to the central processing device 2, and after the central processing device 2 receives the GPS position information, it generates a distress message including the GPS position information, and transmits the distress message to the wireless communication device 4 shown in FIG. 2 The rescue-end electronic device 5 at the remote end. The rescue terminal electronic device 5 may be, but not limited to, a pre-set cloud server, or a pre-set smart phone of a specific contact person. In this way, when the user of the rescue electronic device 5 receives the distress message, he can immediately assign rescue personnel to rush to the location of the car for relevant rescue treatment.

In addition, the central processing unit 2 also stores a third gesture and its corresponding command to record a point of interest; When a gesture appears in the area, and it is judged that the gesture is the third gesture, and it is judged that the third gesture corresponds to the command to record the point of interest, the central processing unit 2 sends the command to record the point of interest to the driving recorder 1, then the driving recorder 1 After the recorder 1 receives the command to record the point of interest, it obtains the current GPS position information of the car through the GPS module 11 and takes a snapshot of the scene, and takes the GPS position information and the scene photo as an interest point, and provide the GPS location information to the central processing device 2, and the central processing device 2 sends the GPS location information to the cloud server, and the cloud server finds the location information from the electronic map according to the GPS location information. A location name related to the GPS position information, and the location name is sent back to the driving recorder 1 through the central processing device 2, so that the driving recorder 1 names the point of interest with the location name, and the point of interest is completed Automatic editing of the point of interest without the need for the driver to re-edit the point of interest after returning home. In this way, when the car is about to pass by the point of interest again, the driving recorder 1 will prompt the point of interest in advance, for example, speaking the place name of the point of interest in the form of voice broadcast.

Moreover, there is also a fourth gesture and a corresponding command to cancel the point of interest in the central processing device 2; thereby, when the driving recorder 1 prompts the point of interest, the driver wants to cancel the point of interest, the The driver can generate a gesture of canceling the point of interest in another nearby area of the steering wheel, so that the camera 3 transmits the image of the gesture generated by the driver to the central processing unit 2, and the central processing unit 2 recognizes the signal from the camera 3. The gesture that appears in the other vicinity of the steering wheel in the image is the fourth gesture, and when it is judged that the fourth gesture corresponds to the command to cancel the point of interest, the central processing unit 2 sends the command to cancel the point of interest to the driving recorder 1, Then, after the driving recorder 1 receives the command to cancel the point of interest, it cancels the point of interest that is being prompted or has just been prompted.

Furthermore, as shown in Figure 2, the central processing unit 2 can also be electrically connected with an advanced driver assistance system (Advanced Driver Assistance Systems, referred to as ADAS) 6 installed on the car, and there is also a The fifth gesture and its corresponding cancel warning command, the cancel warning command is used to control the cancellation of the warning message issued by the advanced driving assistance system; the advanced driving assistance system 6 will detect whether the vehicle has deviated from the lane during driving, Speeding, whether there are pedestrians or vehicles approaching, whether the distance between vehicles is too short, whether a collision is about to occur, etc., and output an early warning message. However, if the warning is too frequent (for example, when there are pedestrians or vehicles approaching and slowly passing by the car, the advanced driving assistance system will continuously send out warning messages) and the driver has noticed the warning event (that is, there are pedestrians or vehicles next to the car. When the vehicle approaches and passes slowly) and does not want to receive the warning message any more, the driver can generate a gesture of canceling the warning in another nearby area of the steering wheel, so that the camera 3 sends the image of the driver's gesture to the central processing unit. device 2, then the central processing unit 2 recognizes that the gesture that appears in the other nearby area of the steering wheel in the image transmitted by the camera 3 is the fifth gesture, and when judging that the fifth gesture corresponds to an instruction to cancel the warning, the central processing unit The device 2 sends the cancel warning command to the advanced driving assistance system 6 to stop sending the warning message.

It is worth mentioning that, in the above-mentioned embodiment, the central processing unit 2 generates a virtual centerline on the steering wheel in the image when recognizing the image transmitted from the camera 3, and the virtual centerline defines the steering wheel symmetrically as a A right half area and a left half area, and the above-mentioned near area is defined as the right half area, and the other near area is defined as the left half area, wherein the driver's operation gesture does not cross the virtual center Therefore, when the central processing unit 2 first judges whether the gesture appearing in the image is located in the vicinity of the steering wheel or the other vicinity, and if so, further recognizes the gesture in the image.

In summary, the above-mentioned embodiment uses the central processing unit 2 to recognize the image around the steering wheel in the car captured by the camera 3 at any time, and recognizes a gesture in the vicinity of the steering wheel in the image, and the gesture corresponds to a control command According to the control instruction, the above-mentioned driving recorder is controlled to lock the gear (and send a distress message at the same time), record (or cancel) the point of interest, or control the above-mentioned advanced driving assistance system to stop outputting the warning message, without the driver Manually looking for the buttons on the driving recorder, the driver only needs to make a gesture on the side of the steering wheel to control the operation of the driving recorder without contact, and indeed achieve the effect and purpose of the present invention.
