Example 1

The invention provides an intelligent security detection system for personnel in a vehicle, which is used for early warning and blocking the door opening intention of the personnel in the vehicle in the driving and parking processes of the vehicle and avoiding unnecessary traffic accidents caused by opening a vehicle door by the personnel in the vehicle under the unconscious and safe conditions.

Specifically, as shown in fig. 1, the detection system includes a vehicle motion detection module 100, an off-board scene acquisition module 200, an in-board scene acquisition module 300, a body language recognition module 400, and a central control module 500.

The vehicle motion detection module 100 includes a motion sensor disposed on the a pillar of the vehicle, the motion sensor is capable of acquiring a moving state of the vehicle in real time, and the vehicle motion detection module 100 sends corresponding vehicle state information to the central control module 500 according to the moving state of the vehicle identified by the motion sensor. Specifically, when the motion sensor recognizes that the moving speed of the vehicle is less than or equal to a preset value, the vehicle motion detection module 100 outputs parameter 1 to indicate that the vehicle is in a parked state; when the motion sensor recognizes that the moving speed of the vehicle is greater than the preset value, the vehicle motion detection module 100 outputs a parameter 0 to indicate that the vehicle is in a driving state.

The vehicle exterior scene acquisition module 200 includes a first camera and a radar arranged at a vehicle trunk, and the radar is embedded in the first camera. The first camera is used for acquiring a first dynamic image of moving objects such as vehicles, pedestrians and the like in the rear direction of the vehicle in real time, and detecting the distance between the moving objects and the vehicle by combining a radar.

In the embodiment of the invention, the first camera and the radar are matched to detect whether a moving object approaches in the detection ranges behind and on two sides of the vehicle. Specifically, moving objects around the vehicle are identified according to the first dynamic image and/or the radar detection result, and a distance value L between each moving object and the vehicle is calculated; and judging whether the distance values L have distance values smaller than or equal to a preset value, if so, indicating that a moving object approaches the periphery of the vehicle, and if not, indicating that no moving object approaches the periphery of the vehicle.

The body language identification module 400 is configured to identify the body movement of the person in the vehicle according to the second dynamic image, so as to determine whether the person in the vehicle has an intention to open the door. Specifically, the CNN convolutional neural network model is arranged in the body language recognition module 400, and after the body voice recognition module acquires the second dynamic image from the in-vehicle scene module, the model can recognize the facial expression, the head action, and the four-limb action of the person in the image, recognize the overall action frequency of the person according to the multi-frame image, and recognize the body languages of the person in the vehicle, such as the turning action, the arm stretching action, and the like based on the feature points (the facial expression, the head action, the four-limb action, and the overall action frequency of the person in the image), so as to recognize whether the person in the vehicle has the door opening intention. After the identification is completed, the body language identification module 400 sends the corresponding identification result to the central control module 500, so that the central control module 500 can judge the risk of opening the door.

The central control module 500 is responsible for receiving the vehicle state information, the approaching conditions of the moving objects at the rear and two sides of the vehicle and the recognition results output by the above modules, analyzing the risk of opening the door of the vehicle interior personnel, and outputting corresponding risk level information.

Specifically, the risk level information has three levels: first-level risk information, second-level risk information and third-level risk information;

when the central control module 500 receives the identification result that the vehicle has the door opening intention and is in the parking state and no moving object exists in the range of 20m around, the door opening risk is low at the moment, and primary risk information is output;

when the central control module 500 receives the identification result that the vehicle has the intention of opening the door and the vehicle is in a parking state and has moving objects within 20m of the surrounding, indicating that the door opening risk is higher at the moment, outputting secondary risk information;

when the central control module 500 receives the recognition result that the door opening intention is met and the vehicle is in a driving state, it shows that the door opening risk is extremely high at the moment, and three-level risk information is output.

The warning module 600 is a player, and the central control module 500 sends a control instruction corresponding to the risk level information to the player while outputting the corresponding risk level information, so as to control the player to play different sounds.

Specifically, when the risk level information output by the central control module 500 is first-level risk information, a first control instruction is sent to the warning module 600, the warning module 600 performs first-level warning according to the first control instruction, and voice broadcast informs personnel in the vehicle of the safety of the environment outside the vehicle and the distance between the vehicle and/or a pedestrian behind the vehicle, and prompts attention to the coming vehicle behind;

when the risk level information output by the central control module 500 is second-level risk information, a second control instruction is sent to the warning module 600, the warning module 600 performs second-level warning according to the second control instruction, and voice broadcast informs people in the vehicle that the environment outside the vehicle is unsafe and the vehicle cannot be opened to get off; the safety of the rear and two sides of the vehicle is determined by visual observation of a driver, and people in the vehicle can safely open the door to get off the vehicle;

when the risk level information output by the central control module 500 is the third-level risk information, a third control instruction is sent to the warning module 600, the warning module 600 performs third-level warning according to the third control instruction, and voice broadcasting informs people in the vehicle that the vehicle is unsafe and the vehicle is not allowed to open the door and get off the vehicle.

The warning module 600 can directly broadcast the risk of the current door opening intention of the person in the vehicle under the condition that the person in the vehicle has the door opening intention, and informs the person in the vehicle of the risk of opening the door and getting off the vehicle when the door opening intention of the person in the vehicle is blocked.
