Description

Technical Field

[0001] The present invention relates to the technical field of in-vehicle mobile phone detection, and more specifically, to a detection method, system and vehicle for preventing a mobile phone from being left behind in a vehicle. Background Art

[0002] As people's living standards improve, vehicles are becoming more and more common in people's lives, adding a lot of convenience to people's lives. During the ride, drivers often need to use mobile phones for navigation, and passengers usually choose to play with their mobile phones to pass the time on the ride. Therefore, it is common for mobile phones to be left in the car after the trip. In order to solve the problem of mobile phones being left in the car, a variety of technical means have been adopted, such as an existing method, system and storage device for alarming the forgotten mobile phone in the car. The method for alarming the forgotten mobile phone in the car includes the following steps: responding to the vehicle locking command, the on-board communication terminal sends information to the owner's mobile phone; through the vibration sensor at the bottom of the mobile phone placement slot and the intelligent cockpit sound collection module, it is determined whether there is a prompt sound and / or vibration in the car, and if there is a prompt sound and / or vibration, an alarm prompt is issued.

[0003] However, the existing technology can only identify whether the owner's mobile phone is left in the car, and cannot effectively identify the mobile phone left in the car by the passenger. However, passengers who play with their mobile phones in the car are more likely to leave their mobile phones in the car. It is difficult for passengers to find their mobile phones in time after leaving them in the car. Generally, passengers will find them after the car drives away. Then, it is difficult for passengers who leave the car after the car drives away to contact the driver in time and take out the mobile phone left in the car. Summary of the invention

[0004] The present invention aims to overcome the problem that the above-mentioned prior art method for warning a forgotten mobile phone in a car cannot quickly warn after a passenger leaves the mobile phone in the car, and provides a detection method, system and car for preventing the mobile phone from being left behind in the car. The detection method in this scheme can promptly detect the mobile phone left behind by the passenger in the car, and remind the passenger before getting off the car, so as to avoid the passenger discovering the left mobile phone after leaving the car, so that the passenger can quickly retrieve the mobile phone left in the car.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a detection method for preventing a mobile phone from being left behind in a car, comprising the following steps:

[0006] Step 1: Start the vehicle;

[0007] Step 2: Detect the distribution of people in the car and the location of the mobile phone, and track the mobile phone after identifying it;

[0008] Step 3: Determine whether the mobile phone is separated from the person, if yes, proceed to step 5, if not, proceed to step 4;

[0009] Step 4: The vehicle stops without any prompt;

[0010] Step 5: The vehicle stops the first prompt and continues to determine whether the person has taken the phone. If yes, proceed to step 4; otherwise, proceed to step 6;

[0011] Step 6: Determine whether the person has gotten off the bus. If yes, proceed to step 7; if not, proceed to step 2.

[0012] Step 7: After the person gets off the car, determine whether the mobile phone is left in the car. If so, give a second reminder, otherwise no reminder will be given.

[0013] The method for determining the mobile phone left in the car in this solution can timely detect the mobile phone left in the car by the passengers, and will give a reminder before the passengers leave the car to remind the passengers that there is a mobile phone left in the car. When the passengers do not find the mobile phone left in the car after getting off the car, they will be reminded again to further reduce the probability of the mobile phone being left in the car. For passengers on the bus, the detection method in this solution can timely detect the mobile phone left in the car by the passengers and give a reminder before the passengers get off the bus, so as to avoid the passengers finding the left mobile phone after leaving the car, and reduce the difficulty for passengers to retrieve the left mobile phone.

[0014] Preferably, in step 2 and step 5, the criterion for determining whether the mobile phone is separated from the person and whether the person has taken the mobile phone is whether the mobile phone screen overlaps with the person screen in the identification image. When the mobile phone and the person are identified separately, the image content is identified after the image is captured by the camera. Therefore, in the image, if the mobile phone screen overlaps with the person screen, it indicates that the mobile phone is on the person, and it can be determined that the mobile phone is not separated from the person.

[0015] Preferably, in step 5, when the first reminder is made, a sound reminder is made in the vehicle and a picture of the location of the mobile phone is displayed on the vehicle display; in step 6, when the second reminder is made, the vehicle horns and the lights flash. When the first reminder is made, the vehicle body makes a sound reminder and an image reminder, which makes it easy for people in the vehicle to find the location of the mobile phone separated from the person in time, avoids the person leaving the mobile phone in the car when leaving the car, and also makes it easy for people to find the mobile phone in time according to the location displayed by the image. When the second reminder is made, the person has left the car, so the vehicle horns and lights flash to remind the people outside the car.

[0016] A detection system for a mobile phone left behind in a vehicle that uses the above-mentioned detection method for a mobile phone left behind in a vehicle comprises a central control system, a tracking and identification system and an alarm system. The tracking and identification system, the central control system and the alarm system are connected in sequence. The tracking and identification system is used to identify the mobile phone in the vehicle and track and locate it. The central control system is used to determine whether a mobile phone is left behind in the vehicle and control the operation of the alarm system. The alarm system is used to remind people that a mobile phone is left behind in the vehicle.

[0017] Preferably, the tracking and identification system includes a first camera located on the A-pillar of the vehicle, a second camera located on the front ceiling of the vehicle, a third camera located on the B-pillar of the vehicle, and a fourth camera located on the rear ceiling of the vehicle. The first camera, the second camera, the third camera, and the fourth camera can all be rotated to adjust their field of view. Rotatable cameras are set on the A-pillar and B-pillar on both sides of the vehicle and the front and rear ends of the ceiling. Through the setting of six cameras, the image inside the vehicle can be effectively captured and identified, and the camera can be rotated so that when the camera recognizes a mobile phone, it can also rotate the direction of the camera according to the change of the position of the mobile phone to track and locate the mobile phone.

[0018] Preferably, before identifying the mobile phone in the car, the tracking and identification system first identifies the person in the car and tracks his / her movements until it identifies that the person in the car takes out the mobile phone, and then transfers the identification and tracking target from the person in the car to the mobile phone. The tracking and identification system first identifies the person in the car, because the user of the mobile phone generally needs to play with the mobile phone in the car before leaving it in the car. By identifying the person in the car and tracking the mobile phone used by the person, the mobile phone that may be left in the car can be quickly located.

[0019] Preferably, when the mobile phone screen that can be obtained by the tracking and identification system is less than 10%-20% of the entire mobile phone screen, the tracking and identification system determines that the mobile phone has disappeared, stops tracking the mobile phone, and re-enters the mobile phone identification preparation. When the available mobile phone screen is less than 10%-20% of the entire mobile phone screen, it means that the mobile phone has been stored by the person in the car at this time, and the part of the mobile phone exposed to the outside will not cause the mobile phone to fall. After determining that the mobile phone has disappeared, re-identification preparation is carried out, that is, the person in the car is re-identified. After recognizing that the mobile phone has disappeared, the person in the car is re-identified to avoid stopping work after losing the tracking target, which can make the identification result more accurate.

[0020] Preferably, the central control system can also determine the location of the mobile phone based on the tracking and identification system, and then calculate the probability that the mobile phone is left behind when the person in the car leaves the car. After the central control system determines that the mobile phone is separated from the person, it can further determine the probability of the mobile phone being left behind based on the location of the mobile phone in the car. For example, the probability of the mobile phone being left behind on the seat is greater than the probability of the mobile phone being left behind on the mobile phone holder. The central control system can also further increase the weight of mobile phone identification and tracking based on the probability of the mobile phone being left behind, and distinguish the degree of alarm according to different weights. When the weight is greater, the alarm sound is louder.

[0021] Preferably, the alarm system includes a car horn, a car light and a vehicle display, and the central control system can control the car horn to honk, the car light to flash and the vehicle display to display the location of the mobile phone left in the car. The alarm system uses the car horn and the car light to remind the person who leaves the car that the mobile phone has been left behind, and uses the vehicle display to remind the person in the car of the location of the mobile phone.

[0022] A car comprises a car body, in which the above-mentioned in-car mobile phone left-behind detection system is arranged.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: the method for determining whether a mobile phone is left behind in the car in the present solution can timely discover the mobile phone left behind by the passengers in the car, and before the passengers leave the car, a reminder will be given to remind the passengers that a mobile phone is left behind in the car. When the passengers do not find the mobile phone left behind in the car after getting off the car, a second reminder will be given, further reducing the probability of the mobile phone being left behind in the car. For passengers on the bus, the present solution can timely discover the mobile phone left behind by the passengers in the car and give a reminder before the passengers get off the bus, avoiding the passengers finding the left mobile phone after leaving the car, and reducing the difficulty for passengers to retrieve the left mobile phone.

[0029] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0030] Example 1

[0031] like Figure 1-Figure 2 An embodiment of a detection method for preventing a mobile phone from being left behind in a vehicle is shown, comprising the following steps:

[0032] Step 1: Start the vehicle;

[0033] Step 2: Detect the distribution of people in the car and the location of the mobile phone, and track the mobile phone after identifying it;

[0034] Step 3: Determine whether the mobile phone is separated from the person, if yes, proceed to step 5, if not, proceed to step 4;

[0035] Step 4: The vehicle stops without any prompt;

[0036] Step 5: The vehicle stops the first prompt and continues to determine whether the person has taken the phone. If yes, proceed to step 4; otherwise, proceed to step 6;

[0037] Step 6: Determine whether the person has gotten off the bus. If yes, proceed to step 7; if not, proceed to step 2.

[0038] Step 7: After the person gets off the car, determine whether the mobile phone is left in the car. If so, give a second reminder, otherwise no reminder will be given.

[0039] Specifically, in step 2 and step 5, the criteria for determining whether the mobile phone is separated from the person and whether the person has taken the mobile phone is whether the mobile phone screen overlaps with the person screen in the recognition image. If the mobile phone screen overlaps with the person screen, it indicates that the mobile phone is on the person, and it can be determined that the mobile phone is not separated from the person.

[0040] Specifically, in step five, when the first reminder is made, a sound reminder is made in the vehicle and a picture of the location of the mobile phone is displayed on the vehicle display; in step six, when the second reminder is made, the vehicle horn is sounded and the lights are flashing.

[0041] Beneficial effects of this embodiment: The method of determining the mobile phone left in the car in this solution can timely find the mobile phone left in the car by the occupants, and will give a reminder before the occupants leave the car to remind the occupants that there is a mobile phone left in the car. When the occupants do not find the mobile phone left in the car after getting off the car, a second reminder will be given to further reduce the probability of the mobile phone being left in the car. For passengers on the bus, the detection method in this solution can timely find the mobile phone left in the car by the passengers and give a reminder before the passengers get off the bus, so as to avoid the passengers finding the left mobile phone after leaving the car, and reduce the difficulty for passengers to retrieve the left mobile phone.

[0042] When the first reminder is made, the car body will give a sound reminder and an image reminder, so that the people in the car can find out in time that the phone is separated from the person and know the location of the phone, so as to avoid the person leaving the phone in the car when leaving the car. When the second reminder is made, the person has already left the car, so the vehicle horn and lights are used to remind the people outside the car.

[0043] Example 2

[0044] Embodiment 2 of a system for detecting a mobile phone left behind in a vehicle for implementing the method for detecting a mobile phone left behind in a vehicle of embodiment 1, as shown in FIG. Figure 3 As shown, a detection system for preventing mobile phones from being left behind in a car comprises a central control system 1, a tracking and identification system 2 and an alarm system 3. The tracking and identification system 2, the central control system 1 and the alarm system 3 are connected in sequence. The tracking and identification system 2 is used to identify the mobile phone in the car and track and locate it. The central control system 1 is used to determine whether a mobile phone is left behind in the car and control the alarm system 3 to work. The alarm system 3 is used to remind people that a mobile phone is left behind in the car.

[0045] Specifically, the tracking and identification system 2 includes a first camera located on the A-pillars on both sides of the vehicle, a second camera located on the front ceiling of the vehicle, a third camera located on the B-pillars on both sides of the vehicle, and a fourth camera located on the rear ceiling of the vehicle. The first camera, the second camera, the third camera and the fourth camera can all be rotated to adjust their field of view.

[0046] Specifically, before identifying the mobile phone in the car, the tracking and identification system 2 first identifies the person in the car and tracks his or her movements until it identifies that the person in the car takes out the mobile phone, and then transfers the identification and tracking target from the person in the car to the mobile phone.

[0047] Specifically, when the mobile phone screen that can be obtained by the tracking and identification system 2 is less than 10%-20% of the entire mobile phone screen, the tracking and identification system 2 determines that the mobile phone has disappeared, stops tracking the mobile phone, and re-enters the mobile phone identification preparation. When the mobile phone screen that can be obtained is less than 10%-20% of the entire mobile phone screen, it means that the mobile phone has been stored by the person in the car at this time, and the part of the mobile phone exposed to the outside will not cause the mobile phone to fall. After determining that the mobile phone has disappeared, the identification preparation is re-performed, that is, the person in the car is re-identified.

[0048] Specifically, the central control system 1 can also determine the location of the mobile phone based on the tracking and identification system 2, and then calculate the probability that the mobile phone is left behind when the occupant leaves the car. The greater the probability of the mobile phone being left behind, the louder the alarm sound.

[0049] Specifically, the alarm system 3 includes a vehicle horn, a vehicle light and a vehicle display, and the central control system 1 can control the vehicle horn to honk, the vehicle light to flash and the vehicle display to display the location of the mobile phone left in the vehicle.

[0050] Beneficial effects of this embodiment: Rotatable cameras are set on the A-pillar and B-pillar of the vehicle and the front and rear ends of the roof. The six cameras can effectively capture and identify the images inside the vehicle, and the cameras can be rotated so that when the camera recognizes a mobile phone, it can also rotate the direction of the camera according to the change of the position of the mobile phone to track and locate the mobile phone. After recognizing that the mobile phone has disappeared, the person in the car is re-identified to avoid stopping work after losing the tracking target, which can make the recognition result more accurate. The alarm system 3 reminds the person who leaves the car of the left mobile phone through the car horn and lights, and reminds the person in the car of the location of the mobile phone through the vehicle display.

[0051] Example 3
