Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
The embodiment of the utility model provides a leave over article detection device in car, as shown in figure 1, the device includes: the system comprises a central processing unit 1, a camera 2, an infrared sensor 3, a voice module 4 and a display module 5 which are connected with the central processing unit 1; the camera 2 is used for shooting a video image in the vehicle and inputting the image into the central processing unit 1, and the central processing unit 1 identifies whether the vehicle is provided with left articles or not by processing the image; the infrared sensor 3 is used for detecting whether a person or a pet is in the car or not and outputting a level state signal to the central processing unit 1; the display module 5 and the voice module 4 are used for displaying and playing the detection result respectively.
In the embodiment, the device mainly comprises a central processing unit 1, and a camera 2, an infrared sensor 3, a voice module 4 and a display module 5 connected with the central processing unit. The following describes each module separately:
the infrared sensor 3 is generally mounted on a seat in a vehicle, and is configured to detect whether a person or a pet is present in the seat, and output a level signal indicating a status (presence or absence) to the central processing unit 1, for example, output a high level indicating a person or a pet, and output a low level indicating no person or a pet. Infrared (or infrared) light has properties of reflection, refraction, scattering, interference, absorption, and the like. Any substance, as long as it has a certain temperature itself (above absolute zero), can radiate infrared rays. The infrared sensor 3 is a sensor for performing measurement using such physical properties of infrared rays. The infrared sensor does not directly contact with a measured object during measurement, so that friction does not exist, and the infrared sensor has the advantages of high sensitivity, quick response and the like.
And the camera 2 is arranged at a place with a wider view line in the vehicle and is used for shooting a video image of an object in the vehicle and sending the video image to the central processing unit 1 for processing and identifying. In principle, the camera 2 should be able to photograph all the positions in the vehicle, and therefore, a plurality of cameras 2 may be provided, and the number and installation positions of the cameras 2 are determined according to the environment in the vehicle. The camera 2 may be an IP network camera, and outputs a digital video image to the central processing unit 1 through network transmission.
The central processing unit 1 is a data processing and control center of the device and is used for finishing various data processing and necessary algorithms and outputting control signals to coordinate the work of each module. For example, the digital image signal input from the camera 2 is subjected to image processing to extract image features, and the image features are matched with the image features of the commonly used important articles stored in the database, thereby identifying the names of the articles in the vehicle. The present embodiment not only identifies the name of the item left behind, but also determines the location of the item within the vehicle. For this purpose, the environment in the vehicle is partitioned, and the position of each carry-over article is represented by the position of the area to which the carry-over article belongs. The environment inside the vehicle is generally divided into the following regions: instrument desk, main driving foot department carpet, vice driving foot department carpet, well row foot department carpet, back row foot department carpet, trunk, storage tank, left front door matter storage lattice, right front door matter storage lattice, left back door matter storage lattice to and right back door matter storage lattice etc..
And the display module 5 is used for displaying the identification result, for example, displaying the name and the position of the left-over article by using characters, and displaying a video image of the left-over article by using a display. The display module 5 can be an LCD/LED display, and can also be realized by a multimedia host and a combination instrument on the vehicle, so that the hardware expense and the space in the vehicle can be saved.
And the voice module 4 is used for playing the recognition result of the central processing unit 1 by voice. For example, under the control of the output signal of the central processing unit 1, all important items in all the zones in the vehicle, all important items in different zones in the vehicle, and the corresponding environment zone of a certain important item are broadcasted.
As an optional embodiment, the device further comprises a vehicle body controller 6 connected with the central processing unit 1, a door touch switch 7 connected with the vehicle body controller 6, and an alarm module 8, wherein the central processing unit 1 acquires the state of the door touch switch 7 through the vehicle body controller 6 to judge whether the vehicle door is closed, outputs a control signal to the vehicle body controller 6, and outputs the control signal to the alarm module 8 through the vehicle body controller 6 to enable the vehicle body controller 6 to send out an alarm signal.
In the present embodiment, by connecting the central processing unit 1 with the vehicle body controller 6 on the automobile, the states of some vehicle body electrical appliances can be acquired or the vehicle body electrical appliances can be controlled. For example, whether the door stopper switch 7 is on or off can be acquired by the vehicle body controller 6. The door catch switch 7 is closed when the door of the vehicle is closed, and is opened or not closed, so that whether the door of the vehicle is opened or closed can be judged; and the times of opening and closing the vehicle door are combined to judge the situations related to getting on and off of the vehicle by the passengers, so that the triggering time of voice playing or alarm prompting is determined. The alarm module 8 is used for warning when the passenger just leaves the vehicle and has articles left on the vehicle. In order to save hardware expenditure, a double flashing light and a buzzer on the vehicle can be used as the alarm module 8.
As an alternative embodiment, the apparatus further comprises a tbox (telematics box)9 on the automobile connected to the central processing unit 1 for implementing data communication between the central processing unit 1 and the mobile phone APP 10.
In this embodiment, remote data communication of the device with the user handset APP10 is achieved by connecting the central processing unit 1 with TBOX9 on the car. After the TBOX9 is connected with the mobile phone APP10 through the cloud platform, all important articles existing in the car and corresponding car interior environment partitions can be pushed to the mobile phone APP10, and a user can check the articles through the mobile phone APP 10; the user can also send the image or name of the item to be identified to the central processing unit 1 through the mobile phone APP 10.
The above description is only for the description of several embodiments of the present invention, but the scope of the present invention should not be considered as the protection scope of the present invention, in which all the equivalent changes or modifications or the equal-scale enlargement or reduction etc. made according to the design spirit of the present invention should be considered as falling into the protection scope of the present invention.
