With continued reference to fig. 1, in one embodiment, the memory 7 further stores a first similarity threshold, and the embedded collation CPU2 includes a similarity determination circuit 21 and a first judgment circuit 22.

The similarity determination circuit 21 takes the target face structured light information and the vehicle owner face structured light information as input, and is configured to determine a face similarity according to an output result, where the face similarity indicates a degree of similarity between the target face structured light information and the vehicle owner face structured light information.

The first determination circuit 22 takes the face similarity and the first similarity threshold as input, and is configured to issue an unlocking instruction when the first determination circuit 22 determines that the face similarity is greater than the first similarity threshold, and issue an unlocking prohibition instruction when the first determination circuit 22 determines that the face similarity is less than the first similarity threshold.

The vehicle door lock control device 3 is further configured to unlock the vehicle door lock according to the unlocking instruction, or further configured to maintain the locked state of the vehicle door lock according to the unlocking prohibition instruction.

In this embodiment, the embedded collation CPU2 may carry a similarity determination circuit 21 and a first judgment circuit 22, and the similarity determination circuit 21 is electrically connected to the memory 7 and the first comparison circuit, respectively.

The specific working process of the similarity determining circuit 21 is as follows: firstly, acquiring target face structured light information of a user from a 3D structured light acquisition device 1 and acquiring owner face structured light information from a memory 7; and then, calculating the target face structured light information and the car owner face structured light information, and determining the similarity between the target face structured light information and the car owner face structured light information, namely determining the face similarity. Specifically, the similarity between the target face structured light information and the owner face structured light information can be determined through a face comparison algorithm.

The specific working process of the first judging circuit 22 is as follows: firstly, the determined face similarity is obtained from the similarity determining circuit 21, and a preset first similarity threshold is obtained from the memory 7; then, comparing the face similarity with a first preset threshold, judging whether the face similarity is greater than or equal to the first similarity threshold, and if the face similarity is greater than or equal to the first preset threshold, indicating that the face image of the user is qualified in verification, namely that the user is a legal user, namely a vehicle owner; if the face similarity is smaller than a first preset threshold value, the verification of the face image of the user is unqualified, namely the user is not a legal user, namely not a vehicle owner. When the verification of the face image of the user is qualified, the first judgment circuit 22 sends an unlocking instruction, the door lock control device 3 can receive the unlocking instruction, so that the automobile door lock is unlocked according to the unlocking instruction, namely, the automobile door is opened for the user to enter, when the verification of the face image of the user is unqualified, the first judgment circuit 22 sends an unlocking forbidding instruction, the door lock control device 3 can receive the unlocking forbidding instruction, so that the automobile door lock is locked according to the unlocking forbidding instruction, namely, the automobile door is not opened.

For example, assuming that the face similarity of the user determined by the similarity determination circuit 21 is 96% and the first similarity threshold is 95%, at this time, the face similarity is greater than the first similarity threshold, the first determination circuit 22 may output an unlocking instruction, and the door lock control device 3 may receive the unlocking instruction, so as to unlock the door lock of the automobile according to the unlocking instruction, at this time, the user may open the door to enter the automobile.

In one embodiment, the first similarity threshold stored in the memory 7 may be modified according to the unlocking usage habit of the user, for example, 95% in the above example, and may also be set to any value between 90% and 100%, which is not specifically limited herein. When modifying, the automobile door is required to be kept open or the automobile door lock is in an unlocked state, namely, the authority of the automobile door lock control system is possessed. However, it should be understood that the larger the first similarity threshold is set, the higher the similarity between the target face structured light information of the user required for unlocking and the previously-entered owner face structured light information is indicated, and in general, due to different time states of people, makeup appearance and the like, the target face structured light information of the same user may have slight difference, so that the difference of a certain numerical range is allowed, that is, in general, the first similarity threshold does not need to be set to 100%.

With continued reference to fig. 1, in one embodiment, the vehicle door lock control system may further include a voice prompt 4 and a communication device 5, the memory 7 further stores a second similarity threshold, and the embedded checkup CPU2 further includes a second decision circuit 23.

When the first determining circuit 22 issues an unlocking prohibition instruction, the second determining circuit 23 takes the face similarity and the second similarity threshold as inputs, and is configured to issue a prompt instruction when the second determining circuit 23 determines that the face similarity is greater than the second similarity threshold, and issue a first warning instruction when the first determining circuit 22 determines that the face similarity is less than the second similarity threshold, where the second similarity threshold is less than the first similarity threshold.

The voice prompt device 4 is configured to send a prompt voice according to the prompt instruction, or send a first alarm sound according to the first alarm instruction, where the prompt voice instructs the user to re-collect, and the first alarm sound is different from the prompt voice.

And the vehicle door lock control device 3 is further configured to keep the vehicle door lock in a locked state according to the prompt instruction or the first alarm instruction.

In this embodiment, the embedded checkup CPU2 may further carry a second determination circuit 23, where the second determination circuit 23 is electrically connected to the memory 7 and the voice prompt apparatus 4, respectively.

The specific working process of the second judgment circuit 23 is as follows: first, it is determined whether the instruction received from the first determination circuit 22 is an unlock instruction or an unlock prohibition instruction, if it is an unlock instruction, the second determination circuit 23 does not perform any processing, and if it is an unlock prohibition instruction, the second determination circuit 23 acquires the determined human face similarity from the similarity determination circuit 21 and acquires a preset second similarity threshold from the memory 7; then, comparing the face similarity with a second preset threshold, judging whether the face similarity is greater than or equal to the second similarity threshold, if the face similarity is greater than or equal to the second preset threshold, indicating that the target face structured light information of the user has higher similarity with the face structured light information of the vehicle owner, and indicating that the user is possibly a legal user; if the face similarity is smaller than a first preset threshold, it is indicated that the target face structured light information of the user and the face structured light information of the vehicle owner have lower similarity, and the user is not a legal user, namely not a vehicle owner. When the user may be a legitimate user, the second judgment circuit 23 sends a prompt instruction, when the user is not a legitimate user, the second judgment circuit 23 sends a first alarm instruction, and the voice prompt apparatus 4 judges whether the instruction received from the second judgment circuit 23 is the prompt instruction or the first alarm instruction, if the prompt instruction is, the voice prompt apparatus 4 sends a prompt voice, and if the first alarm instruction is, the voice prompt apparatus 4 sends a first alarm sound. The prompt voice is different from the first alarm sound, and is used for prompting the user to re-collect, for example, "verify wrong, please re-input"; the first warning sound is used for warning indication, and may be a buzzer sound with a large volume, for example.

The door lock control device 3 also receives the prompt command or the first warning command, but the door lock control device 3 maintains the locked state of the automobile door lock, that is, does not open the door, regardless of the receipt of the prompt command or the first warning command.

In an embodiment, the second similarity threshold stored in the memory 7 may be modified according to the unlocking usage habit of the user, for example, the second similarity threshold may be 85% in the above example, and may also be set to any value between 80% and 90%, which is not specifically limited herein. Likewise, the vehicle door must be left open or unlocked during modification.

In one embodiment, either the prompt voice or the first warning sound may be freely selected and entered into storage by the user in advance.

With continued reference to fig. 1, in one embodiment, the automotive door lock control system may further include a counter 6; the counter 6 is electrically connected to the second determination circuit 23.

The counter 6 is configured to record a total number of times that the second determination circuit 23 issues a continuous prompt instruction within a preset time, and issue a second alarm instruction when the total number of times of the continuous prompt instruction recorded by the counter 6 is greater than the preset number of times, where the continuous prompt instruction means that no other instruction is inserted between two prompt instructions;

the voice prompt device 4 is further configured to send out a second warning sound according to the second warning instruction;

and the vehicle door lock control device 3 is also used for keeping the locking state of the vehicle door lock according to the second alarm instruction.

In this embodiment, the continuous cue instruction is not inserted between two cue instructions, for example, if the instruction issued for the first time by the second determination circuit 23 is a cue instruction, the instruction issued for the second time is a cue instruction, and the instruction issued for the third time is also a cue instruction, the three instructions belong to the continuous cue instruction.

Considering that the voice prompt device 4 prompts the user to re-collect the target face structure light information for unlimited times under the condition that the second judgment circuit 23 sends the prompt instruction, therefore, the counter 6 needs to be set to record the total times of sending the continuous prompt instruction by the second judgment circuit 23 within the preset time, and if the total times of sending the continuous prompt instruction recorded by the counter 6 is greater than the preset times, the counter 6 sends the second alarm instruction. The voice prompt apparatus 4 may generate a second warning sound according to the second warning instruction, where the second warning sound is used for warning prompt, and may be the same as or different from the first warning sound. When the second warning sound is different from the first warning sound, the cause of the warning can be discriminated by the first warning sound or the second warning sound.
