Before the present invention is described in detail, it should be noted that in the following description, similar elements are designated with the same numbering.

Referring to FIG. 1 , it is the main process of an embodiment of the method for controlling a driving recorder by gesture according to the present invention. As shown in FIG. 2 , this embodiment is implemented by a system 100 for controlling a driving recorder by gesture applied to a car. The system mainly includes a driving recorder 1, a central processing device 2 and a camera 3 installed on the car; the driving recorder 1 has a lens module 10, which is mainly used to record images of the interior and exterior of the car, and the The driving recorder 1 combines the functions of video recording, audio recording, screen splitting (such as displaying multiple sets of images taken by multiple camera lenses installed inside and outside the car), alarm, tire pressure, network transmission and GPS support, 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 positioning satellite) module 11, which can obtain the current time from the received global satellite signals, so the recorded images will also include the current time of recording. And because the memory space used to record images in the driving recording device 1 is limited, previously recorded images will be gradually overwritten by images recorded later, that is, the driving recording device 1 will only retain the most recently recorded image.

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 based on the recognition results. The driving recorder 1 operates; for example, the central processing device 2 stores at least a first gesture and a corresponding lock command. The lock command can control the driving recorder 1 to record an image file. Save it.

The camera 3 is electrically connected to the central processing device 2 and is located at an appropriate position in the car. In step S1 of Figure 1 , the camera 3 will capture images around the steering wheel in the car at any time during driving, and record the captured images. sent to the central processing device 2. It is worth mentioning that the camera 3 can be, but is not limited to, a camera installed in a driver monitoring system (DMS) installed on the 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 steering and driving trajectory and/or detecting the driver's posture (such as eye closure, blinking, gaze direction, yawning, 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 access the driver's information. or the image captured by the camera of the surveillance system (i.e., the camera 3).

Next, as shown in step S2 of FIG. 1 , the central processing device 2 identifies the image transmitted by the camera 3 and determines whether the first gesture appears in an area near the steering wheel in the image, such as but not limited to quickly (for example, within 1 second). Make a fist twice (or maintain a fixed gesture, such as a specific gesture, etc.). If so, it is determined that the first gesture appears in the vicinity of the steering wheel, and then find the lock corresponding to the first gesture. and send the lock command to the driving recorder 1; then, as shown in step S3 in Figure 2, when the driving recorder 1 receives the lock command, the currently recorded image file will be saved in an image In a specific folder that cannot be overwritten, the locked image files will not be overwritten by later recorded images. For example, assuming that the driving recording device 1 is set to save the image recorded every minute as an image file in units of 1 minute (not limited to this, the setting can be changed), if the driving recording device 1 is at 4:38 p.m. After receiving the lock command at 25 seconds, the driving recording device 1 will save the images of the interior and exterior of the car recorded from 4:38:01 to 4:38:60 in a specific folder that cannot be overwritten by the image. . In addition, if the driving recorder 1 can record images in units of seconds, when the driving recorder 1 receives the lock command at a certain point in time, it can also take a period of time before and a period of time after the point in time. An image recorded at a certain time (for example, 15 seconds before and 5 seconds after the time point, or 15 seconds before and 15 seconds after) is treated 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 record an emergency video while driving, he only needs to make the first gesture in the area near the steering wheel without having to manually find and operate 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 is not overwritten (overwritten) by subsequent recorded images.

Or, in another implementation mode, when the driving recorder 1 receives the lock command and activates the lock function, and stores the currently recorded image file in a specific folder that cannot be overwritten by the image, the central processing device 2 also According to the image recorded by the driving recorder 1 or the GPS position information of the vehicle provided by the global satellite positioning (GPS) module 11, when it is determined that the vehicle is in a stopped state, the central processing device 2 forces 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 settings), and the central processing device 2 records the image content and sound content of the driving recorder 1 and/or the built-in function of the driving recorder 1 A gravity sensing unit 13 detects a gravity sensing signal, and when it determines that at least two of the following four situations occur, an assist alarm function is activated: (1) The central processing device 2 The image content recorded by the recorder 1 determines that someone continues to approach the vehicle and the distance to the vehicle is less than a preset distance (for example, less than 1 meter) or approaches along the body of the vehicle and leaves the photographic range of the driving recorder 1 (for example, Someone approaches the driver's door of the vehicle along the front of the vehicle); (2) The central processing device 2 determines that someone is holding 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 device 2 recognizes the image content recorded by the driving recorder 1 or based on the gravity sensing unit 13 (such as gravity sensor, G-sensor) built in the driving recorder 1 ), determines that the vehicle has abnormal vibrations (such as someone kicking/pushing the vehicle causing 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.

Among them, the assisting 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 photo in front of the car, the current location information, the default distress content including a mobile phone number, and/or the driving related to at least two conditions for activating the assist alarm function. Related audio and video content recorded by recorder 1. The wireless communication device 4 may be, but is not limited to, a mobile (network) communication module installed in a car and supporting the Internet of Vehicles, or may be a mobile (network) communication module integrated in the central processing device 2 group. And the rescue electronic device 5 can be a cloud server. After receiving the distress message, the cloud server determines that the driver of the vehicle is facing a risk of violence according to the content of the distress message, and directly assists in reporting the nearest police station or police. Otherwise (for example, when the cloud server cannot determine whether the driver of the vehicle is at 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. If it cannot The driver of the vehicle is contacted to assist in notifying the nearest police station or police station.

In addition, the rescue terminal electronic device 5 can also be a computer device located on the police terminal, and the police terminal determines whether to immediately carry out rescue or perform related confirmation actions (such as contacting the rescue terminal) based on the help message received by the rescue terminal electronic device 5 the driver of the vehicle).

In addition, the central processing device 2 also stores a second gesture and a corresponding lock and rescue command, and in the above step S2, when the central processing device 2 recognizes the steering wheel in the image transmitted from the camera 3 When a gesture appears 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) (it can also maintain a fixed gesture, such as making a specific gesture, etc.) , and when it is determined that the second gesture corresponds to the locking and rescue command, the central processing device 2 sends the locking command and a request to provide location information to the driving recorder 1, then in step S3, the driving recorder 1 While retaining the currently recorded image file according to the lock command, the device 1 also obtains the 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 is sent to the central processing device 2, and after receiving the GPS location information, the central processing device 2 generates a distress message including the GPS location information, and sends the distress message to the wireless communication device 4 through the wireless communication device 4 shown in Figure 2. The remote rescue end electronic device 5. The rescue terminal electronic device 5 may be, but is not limited to, a preset cloud server, or may be a preset smart phone of a specific contact person, etc. Thereby, when the user of the rescue terminal electronic device 5 receives the distress message, he can immediately assign rescue personnel to rush to the location of the car to perform relevant rescue operations.

In addition, the central processing device 2 also stores a third gesture and a corresponding recording point of interest instruction; and in the above step S2, when the central processing device 2 identifies the vicinity of the steering wheel in the image transmitted by the camera 3 When a gesture appears in the area, and it is determined that the gesture is the third gesture, and it is determined that the third gesture corresponds to the recording point of interest instruction, the central processing device 2 sends the recording point of interest instruction to the driving recorder 1, then the driving recorder 1 After receiving the command to record the point of interest, the recorder 1 obtains the current GPS position information of the car through the GPS module 11 and snaps a scene photo, and uses the GPS position information and the scene photo as a point of interest. click, and provide the GPS location information to the central processing device 2, and the central processing device 2 transmits the GPS location information to the cloud server. The cloud server finds the corresponding location from the electronic map based on the GPS location information. A place name related to the GPS location information, and the place name is sent back to the driving recorder 1 through the central processing device 2, so that the driving recorder 1 can name the point of interest with the place name, thereby completing the point of interest. Automatically edit the point of interest without requiring the driver to re-edit the point of interest after returning home. In this way, when the car is about to pass the point of interest again, the driving recorder 1 will prompt the point of interest in advance, for example, using a voice broadcast to tell the name of the point of interest.

Moreover, the central processing device 2 also stores a fourth gesture and its corresponding instruction to cancel a point of interest; thereby, when the driving recorder 1 prompts the point of interest and the driver wants to cancel the point of interest, the driver The driver can generate a gesture to cancel the point of interest in another area near the steering wheel, causing the camera 3 to transmit the image of the driver's gesture to the central processing device 2, and then the central processing device 2 will recognize the image from the camera 3. When the gesture appearing in the other nearby area of the steering wheel in the image is the fourth gesture, and it is determined that the fourth gesture corresponds to the point of interest cancellation instruction, the central processing device 2 sends the point of interest cancellation instruction to the driving recorder 1, After receiving the instruction to cancel the point of interest, the driving recorder 1 cancels the point of interest that is being prompted or has just been prompted.

Furthermore, as shown in FIG. 2 , the central processing device 2 can also be electrically connected to an Advanced Driver Assistance System (ADAS) 6 installed on the vehicle, and there is also a central processing device 2 in the central processing device 2 . The fifth gesture and its corresponding cancel warning command are used to control the advanced driving assistance system to cancel the warning message; the advanced driving assistance system 6 will detect whether the vehicle deviates from the lane and whether the vehicle deviates 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 warnings are too frequent (for example, when pedestrians or vehicles continue to approach and pass slowly by the car, the advanced driving assistance system will continuously send out warning messages) and the driver has noticed the warning event (that is, when pedestrians or vehicles continue to approach and pass by the car) When the vehicle is approaching and passing slowly) and no longer wants to receive the warning message, the driver can generate a gesture to cancel the warning in another nearby area of the steering wheel, so that the camera 3 transmits the image of the driver's gesture to the central processing unit Device 2, then the central processing device 2 recognizes that the gesture appearing in the other nearby area of the steering wheel in the image from the camera 3 is the fifth gesture, and determines that the fifth gesture corresponds to the warning instruction. The device 2 sends the warning cancellation command to the advanced driving assistance system 6 to stop issuing the warning message.

It is worth mentioning that in the above embodiment, the central processing device 2 generates a virtual center line on the steering wheel in the image when identifying the image from the camera 3. The virtual center line symmetrically defines the steering wheel into a A right half area and a left half area, and the above-mentioned nearby area is defined as the right half area, and the other nearby area is defined as the left half area, in which the driver's operation gesture does not cross the virtual center line, therefore, the central processing device 2 will first determine whether the gesture appearing in the image is located in the nearby area of the steering wheel or another nearby area, and if so, then further identify the gesture in the image.

To sum up, the above embodiment uses the central processing device 2 to recognize the image around the steering wheel in the car captured by the camera 3 at any time, and a gesture appears in the area near the steering wheel in the recognized image, and the gesture corresponds to a control command. At that time, the above-mentioned driving recorder is controlled according to the control command to lock the gear (and send a distress message at the same time), record (or cancel) points of interest, or control the above-mentioned advanced driving assistance system to stop outputting warning messages without the driver To manually search for the buttons on the driving recorder, the driver only needs to make gestures on the side of the steering wheel to control the operation of the driving recorder without contact, thus achieving the effect and purpose of the present invention.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention.
