Detailed Description
In order to make the implementation objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the drawings in the embodiments of the present application.
The first embodiment of the present disclosure is described in detail below with reference to fig. 1-2, and the present embodiment discloses a vehicle-mounted payment system, which is mainly used for realizing payment of fees generated by parking fees, tolls, and the like in a vehicle through a control device and a projection device equipped in the vehicle without directly interacting with a toll collector and lowering windows or operating a mobile phone by a person in the vehicle in a parking lot or other occasions where the fees generated by the vehicle are to be paid.
The vehicle-mounted payment system disclosed by the embodiment mainly comprises: an in-vehicle control device and a vehicle lamp projection device.
The vehicle-mounted control device is configured to acquire a payment image containing user payment information according to the received payment instruction, and send the image projection instruction and the payment image to the vehicle lamp projection device.
The Vehicle-mounted control device can adopt an IVI system and an IVI (In-Vehicle information) system, namely a Vehicle-mounted information entertainment system, which are equipped In a Vehicle, and a Vehicle-mounted integrated information processing system is formed by adopting a Vehicle-mounted special central processing unit based on a Vehicle body bus system and internet services, and can realize a series of applications including three-dimensional navigation, real-time road conditions, IPTV, auxiliary driving, fault detection, Vehicle information, Vehicle body control, mobile office, wireless communication, online-based entertainment functions, TSP (short message service) services and the like. In this embodiment, commonly used APPs having a payment function, such as a payment treasure and a WeChat, may be installed in the vehicle-mounted control device in advance, for example, the payment treasure and the WeChat APP are preinstalled in the IVI host of the IVI system.
The vehicle lamp projection device is configured to control the DLP vehicle lamp to project the payment image to a position area outside a vehicle body according to the image projection instruction.
The vehicle Light projection Device may adopt a DLP (Digital Light processing) vehicle Light projection system, which is a Digital Light processing technology, and employs a Digital Micromirror Device (DMD) as a main key element to implement a Digital optical processing process. The projection principle of the DLP technology is to homogenize the light from the light source by an Integrator, divide the light into R, G, B three colors by a color wheel (ColorWheel) with three primary colors, image the colors on the DMD by a lens, convert the electrical signal of the digital rotating lens into gray scale by a synchronous signal method, express the colors by matching R, G, B three colors, and finally project and image the color through a lens. The image projected by applying the DLP technology has higher contrast, and has great advantages when a pattern which comprises color blocks and has strong color contrast among different blocks, such as a two-dimensional code, is projected.
In the DMD, a matrix of micromirrors (precision, micro mirrors) is disposed on a semiconductor chip, each micromirror controls a pixel in a projection screen, the number of the micromirrors matches the resolution of the projection screen, the micromirrors can change angles rapidly under the control of a digital driving signal, and the micromirrors tilt by 10 degrees when receiving a corresponding signal. Essentially, the angle of the micromirror has only two states: on and off. If the micro-mirror in the projection state is shown as "on", the micro-mirror is tilted by +10 degrees along with the digital signal, and the reflected incident light will affect the projection on the screen through the projection lens; if in the non-projecting state, it is shown as "off", tilted-10 degrees, and the incident light reflected on the micromirror is absorbed by the light absorber.
The DLP vehicle lamp projection system specifically comprises a DLP vehicle lamp controller and a DLP vehicle lamp, wherein the DLP vehicle lamp controller is electrically connected with an IVI host of the IVI system and used for receiving a to-be-projected image sent by the IVI host. The DLP vehicle lamp can adopt a front vehicle lamp (headlamp) as a projection lamp, and a projected picture is positioned on the front side of a vehicle body at the moment; a rear vehicle lamp (tail lamp) can also be adopted, and the projected picture is positioned at the rear side of the vehicle body; a new vehicle lamp mounted on the side of the vehicle body can also be adopted, and the projected picture is positioned on one side of the vehicle body. In the embodiment, as shown in fig. 2, left and right front lamps are used as DLP lamps for projection.
DLP car light is connected with DLP car light controller electricity for receive DLP car light controller control will treat the projection image to project to the external world.
The working process of the vehicle-mounted payment system is as follows: taking a parking lot as an example, when a vehicle is driven away from the parking lot, an exit of the parking lot is blocked by a parking rod, an attended person or an unattended self-service toll collector can prompt a user to pay parking fee, the user selects a one-key payment option on an on-board control device, the on-board control device receives a one-key payment instruction sent by the user and dynamically acquires a default dynamic payment code of a payment APP of the user according to the instruction, the dynamic payment code comprises user payment information, then the on-board control device transmits an image projection instruction and image information of the dynamic payment code to a DLP (digital light processing) vehicle lamp controller of a DLP (digital light processing) vehicle lamp projection system in real time, the DLP vehicle lamp controller executes the received image projection instruction, analyzes the image information, and controls a left headlamp and a right headlamp of the vehicle to project a payment code pattern to a DLP (digital light processing) lamp (digital light processing) on the ground, wherein the DLP lamp is located in front of the vehicle head and is separated from the vehicle head by a certain distance In a certain area range, a projection pattern as shown in fig. 2 is formed, for example, a two-dimensional code pattern with an area of 1 square meter is projected to a position 1 meter in front of a vehicle head, and since the height of a parking rod of a barrier gate is usually not lower than the ground clearance of a vehicle lamp, and a certain distance is left between the vehicle lamp and the parking rod, the projection direction is obliquely downward, the parking rod cannot block the light projection, then a charging booth at an exit of a parking lot can locate and identify a projected payment code, and payment information of a user is acquired by scanning the code, so that parking fee deduction is performed, and a self-service parking fee payment process of getting-free and getting-down-free vehicle windows is completed.
If the DLP lamp is a tail lamp, the projection screen is located in a rear area outside the vehicle body, and if the DLP lamp is a side lamp added to the vehicle body, the projection screen is located in a side area outside the vehicle body.
It can be understood that, the toll collector may set a range identifier on the ground or other location for specifying the projection area in advance, for example, in fig. 2, the square block identifier a is used on the ground to specify the projection area as the target projection area in the area, the square block identifier a may be used as the projection area identifier, that is, a range identifier set by the toll collector on the ground or other location for specifying the projection area in advance, the user needs to project the payment code into the square block identifier a, the toll collector may directly scan the payment code by using the barcode scanner aligned with the square block identifier a through the pre-directional calibration, the projected payment code does not need to be located every time of charging, and the barcode scanning success rate of the toll collector is improved.
In addition, in order to further increase the diversity of vehicle payment modes, the user can be equipped with the ETC in the vehicle and pay at a highway toll station through the ETC, the license plate can be bound with the bank card by the user, the license plate is identified by the toll station and the payment is automatically carried out, and the traditional payment modes such as ETC and license plate identification can be combined with the payment system provided by the application on the vehicle.
The disclosed on-vehicle payment system of this embodiment, need not the user and descend the door window to show the two-dimensional code on the cell-phone and sweep the sign indicating number for on duty personnel or self-service toll collector, but IVI system and DLP car light that in the car direct control vehicle self was equipped with, the show mode of the two-dimensional code that will give the toll booth has become the projection to subaerially, the illumination with the help of the car light makes the projected two-dimensional code very clear and the area is big, it sweeps the sign indicating number charge to do benefit to the toll collector, whole payment flow convenient and fast, it is efficient to collect fees, need not interior personnel's operation cell-phone, also can not delay because of too far away from on duty personnel or self-service toll collector and sweep the sign indicating number time, and also need not the user to install additional equipment such as ETC in advance, the cost of collecting is reduced, can satisfy the humanized, automation, the demand of convenience of people to collecting fees.
When the charge is completed by the attendant or the self-service toll collector of the parking lot toll booth, the user is prompted to complete the payment, and at this time, the user needs to turn off the projection and drive away from the parking lot, so in one possible embodiment, the vehicle-mounted control device is further configured to: and sending a projection stopping instruction to the vehicle lamp projection device according to the received payment finishing instruction. The vehicle light projection device is further configured to: and controlling the DLP vehicle lamp to stop projection according to the projection stopping instruction.
The payment completion indication can be completed by operating the vehicle-mounted control device (IVI system) by a user, for example, the user hears a voice prompt that payment is completed and sent by an attendant or a self-service toll collector, or the user sees a word that payment is completed and displayed on a display screen of the self-service toll collector, namely, an option of closing projection can be selected on the vehicle-mounted control device, the option is equivalent to the payment completion indication, and then, the DLP vehicle lamp stops projection.
At present, a large number of parking lot toll booths adopt an unattended self-service toll collector to collect the parking fee at an exit of the parking lot, so that in order to improve user experience and increase automation degree and convenience of a payment process, in one possible implementation mode, the payment indication and/or the payment completion indication are voice prompts sent by a toll collector. And the vehicle-mounted control device comprises a vehicle-mounted voice recognition module, the vehicle-mounted voice recognition module comprises a voice collection device which is externally arranged on the outer side of the vehicle body and is close to a left driving seat, for example, a miniature microphone can be used as the voice collection device, the collected voice information is transmitted to the vehicle-mounted voice recognition module in real time through the voice collection device, the vehicle-mounted voice recognition module extracts a voice prompt from the voice collection device, carries out semantic recognition on the voice prompt, converts a recognition result into corresponding indication information and sends the indication information to the vehicle-mounted control device, wherein the indication information is the payment indication or the payment completion indication.
That is to say, the acquisition mode of the indication is not that the user selects the option on the screen in the IVI system, but when the self-service toll collector sends a voice prompt of "please pay XX-unit parking fee", for example, the vehicle-mounted voice recognition module recognizes the external voice signal in real time, and thus recognizes the voice prompt of "please pay XX-unit parking fee", and at this time, the vehicle-mounted voice recognition module determines the meaning of the voice prompt through semantic recognition, selects the indication information corresponding to the meaning, namely, "payment indication" from the indication information base, and sends the indication information to the vehicle-mounted control device, and finally triggers the payment code projection.
The specific semantic recognition process may be: after the voice signals are collected, the voice signals are firstly segmented by judging the volume of the voice signals, because the voice signals are not sounded before and after the voice prompts are sent out, the voice signals containing the voice prompts can be segmented from all the received voice signals through the volume, then the segmented voice signals are converted into text forms through a voice recognition technology, the meaning of the voice prompts is obtained, the voice prompts are sent out by a machine, the recognition rate is high, then the converted texts (namely the meaning of the voice) are compared with a plurality of kinds of text information prestored in an indication information base one by one, the text information with the highest similarity is determined by utilizing the number of overlapped characters and the character length of a public character string, and the text information is used as the indication information corresponding to the voice prompts. The speech recognition method is not limited to this, and is not listed here.
Similarly, for the 'payment completion indication', when the self-service toll collector finishes scanning the projected codes, automatically sends out a voice prompt such as 'successful payment', the vehicle-mounted voice recognition module also recognizes the voice prompt, determines that the 'payment completion indication' is the indication information matched with the meaning of the voice prompt from the indication information base, and finally triggers the projection to be closed after sending the indication information to the vehicle-mounted control device.
The full-automatic projection control is carried out through voice recognition, and the whole payment process does not need user participation, so that the payment is more humanized.
For the scene with the projection area identifier, in order to avoid that the user vehicle cannot correctly scan the user payment code due to the fact that the projection picture is located outside the target projection area (the projection identification area specified by the toll collector) due to different vehicle positions, vehicle types and the like, the toll collector may set the area of the target projection area to be obviously larger than the area of the actual projection picture of a general vehicle, so that the actual projection picture is easier to fall into the target projection area completely, and the toll collector also sets the code scanning range of the code scanning device to cover the whole target projection area, so that the function of being adaptive to the target projection area and successfully scanning the projection picture payment code is realized. However, no matter the toll collector adopts manual code scanning or automatic code scanning of equipment, sometimes it may happen that all ranges of a target projection area cannot be covered when code scanning is caused due to reasons such as barrier shielding, and the like, so that the payment code pattern projected by a user cannot be identified, therefore, in a possible implementation manner, in the DLP car lamp projection process, the vehicle-mounted voice identification module collects the picture position adjustment prompt sent by the toll collector in real time and carries out semantic identification, converts the identification result into corresponding positioning indication information and sends the positioning indication information to the vehicle-mounted control device, the vehicle-mounted control device sends a corresponding car lamp swing instruction to the car lamp projection device according to the positioning indication information, and the car lamp projection device controls the DLP car lamp to swing in the corresponding direction according to the car lamp swing instruction.
Assuming that the target projection area is a 4 × 4 square area, the actual projection picture of the vehicle to be paid is a 2 × 2 square area, and the current projection position is located at the upper right corner inside the target projection area, at this time, due to obstruction, the code scanning device of the self-service toll collector or an attendant in the toll booth cannot collect the content at the upper right corner of the target projection area, and thus, the payment code cannot be identified. At the moment, the self-service toll collector identifies the fault reason through failure of scanning the current code, determines that the payment code cannot be scanned completely due to shielding, and therefore the self-service toll collector can send out a corresponding picture position adjustment prompt through a voice device, such as 'left projection', and for a toll booth on duty manually, a worker can also say 'turn left to adjust one by one' when finding that the code cannot be scanned normally due to an obstacle. The vehicle-mounted voice recognition module of the vehicle-mounted control device can collect external voice signals in real time after DLP vehicle lamp starting projection, collect picture position adjustment prompts of 'left projection' or 'adjustment one to the left' in modes of voice signal extraction and the like, determine the meanings of the picture position adjustment prompts after semantic recognition, and select positioning indication information corresponding to the meanings from an indication information base, wherein the semantic recognition mode can be the same as the mode for recognizing the voice prompts in the foregoing, and the positioning indication information at the moment contains an indication for enabling the vehicle lamp to swing a certain angle to the left. Later by on-vehicle controlling means generation car light swing instruction, car light swing instruction this moment can be "left pendulum 10 degrees", after car light projection arrangement received this car light swing instruction, the DLP car light can be according to left pendulum 10 accordingly for the actual projection picture moves the position that is close to the upper left corner of target projection area, has avoided sheltering from of barrier, makes self-service toll collector sweep yard equipment or the interior keeper of toll booth sweep the sign indicating number correctly.
There are many scenarios for instant payment in a vehicle, such as paying parking fees in a parking lot, paying tolls in a highway toll station, etc., and different environmental conditions in different scenarios may have a certain effect on the scanned code recognition after projection, so in one possible embodiment, the system further includes a light sensor installed on the vehicle body in order to eliminate the effect of some environmental conditions. The light sensor is also called a brightness sensor and can sense the brightness of the surrounding environment. The vehicular lamp projecting device is further configured to: after the image projection instruction is received, the ambient brightness detected by a light sensor installed on a vehicle body is obtained, and the brightness and/or contrast of the DLP vehicle lamp is adjusted according to the ambient brightness in the process of controlling the projection of the DLP vehicle lamp.
When the ambient brightness is higher, the vehicle lamp projection device can control the DLP vehicle lamp to carry out brightness improvement of corresponding degree, or contrast improvement of corresponding degree, or simultaneously improve brightness and contrast, so that code scanning failure caused by too dark or fuzzy projected images can be avoided during code scanning of a toll collector. Specifically, since the DLP technology belongs to a reflective projection mode, it mainly changes the brightness and contrast of a projection picture by improving a color wheel technology, changing a micromirror inclination angle, reducing a light path loss, and the like. When the ambient brightness is lower, the car light projection device can also control the DLP car light to properly reduce the brightness and contrast of a projection picture, so that exposure during code scanning is avoided and energy conservation is realized.
