The Memory 1005 may be a Random Access Memory (RAM) or a Non-Volatile Memory (NVM), such as a disk Memory. The memory 1005 may alternatively be a storage device separate from the processor 1001.
It will be appreciated by those skilled in the art that the configuration shown in fig. 1 does not constitute a limitation of the living-body detecting apparatus, and may include more or less components than those shown, or some components may be combined, or a different arrangement of components.
As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a life body detecting program.
In the living body detecting apparatus shown in fig. 1, the network interface 1004 is mainly used for data communication with a network server; the user interface 1003 is mainly used for data interaction with a user; the processor 1001 and the memory 1005 in the living body detecting device of the present invention may be provided in the living body detecting device, which calls the living body detecting program stored in the memory 1005 through the processor 1001 and executes the living body detecting method provided by the embodiment of the present invention.
Based on the above living body detection device, an embodiment of the present invention provides a living body detection method, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of the living body detection method according to the present invention.
In this embodiment, the living body detecting method includes the steps of:
step S10: and when the vehicle-interior passenger leaving behavior is detected, the prerecorded living body position information is acquired.
It should be noted that the execution main body of the embodiment may be a computing service device with data processing, network communication and program running functions, such as a mobile phone, a tablet computer, a personal computer, etc., or an electronic device or a living body detection device capable of implementing the above functions. The present embodiment and the following embodiments will be described below by taking the living body detecting apparatus as an example.
It should be noted that the vehicle occupant may be a driver or other vehicle personnel, and specifically, the detection may be performed by whether a vehicle door is opened, whether a seat belt is unfastened, and by a camera and a radar inside the vehicle. For example, when a door at the driver's position is opened and a camera in the front row of the vehicle detects that there is no life at the driver's position, it may be determined that the driver is away from the vehicle. The living body position information may be position information of a living body located inside the vehicle or position information of a plurality of living bodies respectively located.
Further, in order to detect whether there is a living body in the vehicle more accurately, before step S10, the method further includes: when the opening of the vehicle door is detected, acquiring the life body information of a target life body through a sensor at a preset position; calling a preset sensor to perform reinspection confirmation according to the life body information to obtain an reinspection result; and taking the rechecking result as the life body position information of the target life body.
The sensor at the preset position and the preset sensor may be a pressure sensor mounted on or near a seat of the vehicle, such as a pedal, or may be a sensor such as a camera mounted on a front row of the vehicle or a radar mounted on a rear row of the vehicle, or a carbon dioxide concentration detector. The living body information may be position information of the living body acquired by a sensor at the preset position. The calling of the preset sensor according to the vital body information for retest confirmation may be to retest the vital body information through a camera in the front row of the vehicle and/or a radar in the rear row of the vehicle to obtain a retest result, where the retest result may include the number of vital bodies in the vehicle and location information of each vital body.
In specific implementation, for example, after the door sensor detects that the door is opened, the pressure sensor first detects the door, preliminarily confirms the position of the living body, and if the door is in the front row, the camera performs rechecking confirmation; and if the data is in the rear row, recheck confirmation is carried out through the radar. If any sensor detects that the living body moves, rechecking confirmation is carried out according to the mode of the front row camera/the rear row radar, and the memory accuracy of the position of the living body is ensured. Under some special conditions, after the door sensor detects that the door is opened, the pressure sensor detects that no life body exists in the front row and the back row of the vehicle, and the front row still needs to be rechecked and confirmed in a radar mode through the camera and the back row. And if the front row of cameras and the rear row of radars do not detect the living body, confirming the inanimate body. Or the door sensor detects that the door is opened the back, to the front row, if pressure sensor detects the front row inanimate object, when the front row camera detected the front row animate object, then use camera detection result as the standard to when the front row animate object position moved, still can gather the information of animate object, and record the animate object position.
In specific implementation, after the door sensor detects that the door is opened, the door sensor is used for detecting the following steps of: if pressure sensor detects the back row inanimate body, and the front camera detects the back row inanimate body, and the back radar detects the back row animate body, then use radar detection result as the standard, the priority that the testing result adopted is that the back radar is greater than the front camera for the back radar and is greater than pressure sensor to when the back row animate body position removed, still can remember the animate body position. For the back row, if the pressure sensor detects that a back row living body exists, the front row camera detects that the back row living body exists, and the radar detects that the back row living body does not exist, the back row radar needs to perform rechecking confirmation. If the radar detects that a life body exists in the back row, confirming the position of the member, and still memorizing the position of the life body when the position of the life body moves; and if the radar detects the rear-row inanimate object, the radar detection result is taken as the standard. Specifically, if the position of the living body determined by the pressure sensor is different from the camera and the radar, the front row is based on the camera recheck confirmation result, and the rear row is based on the radar recheck confirmation result.
Step S20: and calling a preset sensor to detect the life body according to the life body position information to obtain a detection result.
The preset sensor may be a camera mounted on the front row of the vehicle, a radar mounted on the rear row of the vehicle, a carbon dioxide concentration detector, or the like. The calling of the preset sensor according to the position information of the living body can be calling different sensors according to the position of the living body to detect, for example, when the living body is determined to be in the front row of the vehicle according to the position information of the living body, the camera mounted in the front row of the vehicle is used for detecting, when the living body is determined to be in the rear row of the vehicle according to the position information of the living body, the radar mounted in the rear row of the vehicle is used for detecting, and when the living body is determined to exist in the front row and the rear row of the vehicle according to the position information of the living body, the front row camera and the rear row radar are used for respectively detecting. And obtaining a detection result.
Step S30: and when the detection result indicates that the living body exists, ensuring the safety of the living body according to a preset guarantee strategy.
It should be noted that the preset safeguard strategy can guarantee the life safety of the life body in the vehicle by adjusting the air conditioner inside the vehicle, and timely remind the driver that the life body is left over in the vehicle when the life body exists in the vehicle.
The method comprises the steps that pre-recorded position information of a living body is obtained when the fact that a passenger in the vehicle leaves the vehicle is detected; calling a preset sensor to perform life detection according to the life position information to obtain a detection result; and when the detection result indicates that the living body exists, the safety of the living body is guaranteed according to a preset guarantee strategy. In the embodiment, when the in-vehicle passenger leaving behavior is detected, the preset sensor is called according to the position information of the living body to detect the living body, so that a detection result is obtained; and when the detection result indicates that the living body exists, the safety of the living body is guaranteed according to a preset guarantee strategy. Compared with the existing mode of detecting the life body only through the camera, the mode of the embodiment detects the life body according to the position information of the life body, and guarantees the safety of the life body according to the preset guarantee strategy when the life body exists. Whether a life body exists on the vehicle can be judged more accurately, and the safety of the life body is guaranteed.
Referring to fig. 3, fig. 3 is a flowchart illustrating a second embodiment of the method for detecting a living body according to the present invention.
Based on the first embodiment described above, in the present embodiment, the step S20 includes:
step S201: and acquiring the detection position of the living body according to the living body position information.
It should be noted that the detection position may be a position where a living body exists in the vehicle, which is determined according to the living body position information, for example, a front-row position of the vehicle and/or a rear-row position of the vehicle.
Step S202: and judging whether the detection position comprises a front row seat position.
It should be noted that the detection position may include one or more of a front seat position and/or a rear seat position, and when the detection position includes the front seat position, the front seat position needs to be detected, and when the detection position includes both the front seat position and the rear seat position, both the front seat position and the rear seat position need to be detected.
Further, in order to accurately detect whether there is a living body on the vehicle, after step S202, the method further includes: when the detection position does not comprise the front seat position, detecting whether the life body exists at the rear position of the vehicle through a preset vehicle radar; and when the life body exists at the back row position, the safety of the life body is guaranteed according to a preset guarantee strategy.
The preset vehicle radar may be a radar installed at a preset position of the vehicle, and may be a radar capable of detecting a living body, such as a microwave radar, a millimeter wave radar, and a laser radar. The mounting positions may be positions of a rear seat, a rear door, and a roof of the vehicle.
It will be appreciated that depending on the FOV view, the front row of cameras can detect the front and back row partial positions, while the back row of radars can only detect the back row position. For the back row, the accuracy of radar detection is higher than that of camera identification. Therefore, the radar is used in the present embodiment to detect whether there is a living body in the rear row of the vehicle.
In a specific implementation, when the detected position does not include the front seat position and the rear seat position, the rear radar is called first to detect. For the back row, if the back row radar detects that a life body exists in the back row, a preset safeguard strategy is adopted to guarantee the safety of the life body. And if the back-row radar detects the inanimate object, calling the front-row camera to perform re-detection. If the front row of cameras detect that life bodies exist in the rear row, the back row of radar needs to be subjected to re-detection. And when the retesting indicates that the back row exists in the life body, the safety of the life body is guaranteed according to a preset guarantee strategy by taking the result of the retesting as the standard. And if the back row radar detects the inanimate object during the repeated detection, confirming the back row inanimate object. For the front row, if the front row camera detects that a living body exists in the front row, the safety of the living body is guaranteed according to a preset guarantee strategy. And if the front row camera detects the front row inanimate object, confirming the front row inanimate object. That is, when the detected position does not include the front seat position and the rear seat position, the radar is first used to detect whether a living body is present in the rear seat, and then the camera is used to detect whether a living body is present in the front seat. The camera can detect the living body at the front seat position and can also detect the living body at the rear seat position.
Step S203: when the detection position comprises the position of the front seat, the detection of the living body is carried out through a preset camera arranged on the front row of the vehicle, and a detection result is obtained.
The detection result may be a detection result of whether or not a living body is present in the front seat, and when the detection result indicates that no living body is present in the front position, it may be determined that no living body is present in the front row of the vehicle.
In specific implementation, when the living body position information shows that a front row of living bodies and a rear row of non-living bodies exist, the detection position comprises the position of a front row seat and does not comprise the position of a rear row seat, and a front row camera is called first for detection. For the front row, if the front row camera detects that a living body exists in the front row, the safety of the living body is guaranteed according to a preset guarantee strategy. And if the front row camera detects the front row inanimate object, determining the front row inanimate object by taking the detection result of the camera as the standard. For the back row, if the front row camera detects that there is a living body in the back row after the front row inanimate body, the radar needs to be called to perform the re-detection. And if the radar detects that a life body exists in the back row, the safety of the life body is guaranteed according to a preset guarantee strategy. And if the radar detects the rear row inanimate object, confirming that all the front row and the rear row are inanimate objects based on the radar monitoring result.
If the front row camera detects that the front row and the back row are not provided with the living bodies, the radar still needs to be called to perform the re-monitoring of the living bodies in the back row, and if the radar detects that the living bodies in the back row exist, the monitoring result of the radar is used as the standard, and the safety of the living bodies is guaranteed according to a preset guarantee strategy. And if the radar detects the rear row of inanimate objects, confirming that the front row and the rear row are inanimate objects.
In a specific implementation, when the living body position information shows that living bodies exist in both the front row and the rear row, the detection position includes the front-row seat position and the rear-row seat position. The front row of cameras is called first to perform detection. And if the front row camera detects that a life body exists in the front row, the safety of the life body is guaranteed according to a preset guarantee strategy. If the front row of cameras detect that no living body exists in the front row and a living body exists in the rear row, a rear row of radar is required to be called for re-detection. And if the back-row radar detects a living body, ensuring the safety of the living body according to a preset guarantee strategy. And if the rear-row radar detects the inanimate object, confirming that both the front row and the rear row are inanimate objects on the basis of the detection result of the rear-row radar. If the front row of cameras detect that no life body exists in the front row and the back row, the back row of radars are required to be called for re-detection, and if the back row of radars detect that a life body exists in the back row, the safety of the life body is guaranteed according to a preset guarantee strategy. And if the rear-row radar detects the rear-row inanimate object, confirming that the front row and the rear row are inanimate objects.
Further, in order to accurately detect whether a living body exists in a vehicle, after the step of detecting whether the living body exists in a rear position of the vehicle by a preset vehicle radar when the detection position does not include the front seat position, the method further includes: when the living body does not exist at the rear row position, acquiring the concentration of carbon dioxide in the vehicle through a preset carbon dioxide detector; judging whether the concentration of the carbon dioxide in the vehicle is increased or not according to the concentration of the carbon dioxide; and when the concentration of the carbon dioxide in the vehicle is increased, calling a preset sensor to detect the living body, and obtaining a detection result.
It should be noted that the preset carbon dioxide detector may be a carbon dioxide detector installed inside a vehicle. Carbon dioxide concentration can include a plurality of carbon dioxide concentrations in certain time period, compares a plurality of carbon dioxide concentrations, can judge in a certain time, and carbon dioxide concentration risees, when carbon dioxide concentration risees, can tentatively judge to have the life body in the car, and at this moment, whether there is the life body in to the car through camera and radar and detect. Specifically, whether a living body exists in the front row of the vehicle or not is detected through a camera, and whether a living body exists in the rear row of the vehicle or not is detected through a radar.
In specific implementation, when the in-vehicle inanimate object is determined through the position information of the inanimate object or confirmed through a camera and a radar, the in-vehicle inanimate object is detected again through a carbon dioxide detector.
