DESCRIPTION OF THE DRAWINGS

[0043] The further characteristics and details of the invention result from the claims and from the following description of a preferred non-limiting embodiment, represented in the attached drawings:

[0044] FIG. 1: shows a first flow diagram of a method according to the invention,

[0045] FIG. 2: shows a second flow chart of a method according to the invention,

[0046] FIG. 3: shows a third flow chart of a method according to the invention.

DETAILED DESCRIPTION OF THE INVENTION

[0047] In FIG. 1, the reference number 100 indicates a flow chart of a first method according to the invention in which in the first step 101 an image is acquired, for example by means of a camera, from the carrier vehicle. The image is preferably acquired in the opposite direction to the direction of travel of the carrier vehicle.

[0048] In step 102 the acquired image is modified if necessary. This means that the image is processed by deleting the data that can lead to the unique identification of an observing person and/or vehicle. In this phase, for example, the license plate of an observing vehicle is cancelled. In step 103 the original photo is deleted. This happens without the original photo being saved.

[0049] In a subsequent step 104 the image, which in step 102 had already been deprived of personal identification data, is analyzed and is processed. In this phase, for example, the type of vehicle being observed is identified, such as for example a convertible, SUV, truck, etc. or other elements such as, for example, the make of the vehicle: Mercedes, Audi, VW, etc. After identification of the predetermined relevant data in the image, the processed image is also deleted. Simultaneously with the steps 102 to 105, the data for example of the position of the carrier vehicle are determined in the step 106 by means of a GNSS device and other data are acquired by sensors in the step 107. This further data can be, for example, the amount of light, the characteristics of the surrounding environment, temperature, weather, road conditions, etc.

[0050] This data is paired with the data retrieved from the image cleansed of personally identifying data.

[0051] In the next step, 108, the system makes a random choice, adds “statistical noise” according to pre-set parameters to the data detected in step 107. In step 109, the data, original or altered in step 108, are analyzed together with the data retrieved from the sensors in the step 106 and 107 to choose an advertisement in step 110.

[0052] If by probabilistic choice in step 108 the data retrieved previously are deleted, an advertisement/information is chosen at random from the database of land vehicles in step 111.

[0053] In step 112, advertising or information selected according to the method in a first embodiment is displayed on a device, for example a screen installed on a carrier vehicle. This first embodiment does not require a connection to external databases and the whole process or method is performed locally on the carrier vehicle itself. This is particularly advantageous since the system can hardly be subjected to external attack and possibly manipulated to use the sensors, in particular the devices to acquire the image or to retrieve information or to carry out unwanted surveillance. For this reason, the operator and/or owner of the system according to the invention easily fulfills the strict rules for the management of personal data regarding privacy.

[0054] However, access from the outside can always take place to the parameter structure and/or database of the system. In this way, the information to be published or the parameters that regulate the system can be modified. Furthermore, statistical data can be derived in this way.

[0055] In a second embodiment illustrated in the second diagram 200 of the method according to the invention, an image is acquired in step 201. Subsequently, one passes to step 202 in which, based on the result of a random number generator and pre-set parameters, it is chosen whether the captured image is routed according to path A or path B.

[0056] During path A the personal identification data are eliminated in step 203 and then in step 204 the original image, i.e. with the data which refer to the person or which allow an identification as previously described in step 102 is eliminated.

[0057] If path B is chosen in step 202, the original image is immediately canceled in step 205 and replaced with a plausible random image in step 206 present in the database of land vehicles, for the purpose of decreasing the probability of re-identification thus safeguarding privacy of the people of the observing vehicle, replace the same with a random image present in the archive or with random information.

[0058] At the end of step 204 or 206, step 207 is performed. In this case, the GNSS data suitable for identifying the position of the carrier vehicle are associated with the image created in step 203 or with the image retrieved from the database in step 206. Then in step 208 the data from the other sensors are added to the image as previously described in the first embodiment of the method at 106 and 107.

[0059] In step 209 the image with the respective data is sent by means of a wireless system, for example by means of a data connection in the mobile telephony network and/or the like to an external server. Simultaneously in step 210 the image and data are deleted locally, i.e. on the device.

[0060] In step 211 the image with the data is processed on the external server by extracting the characteristics of the vehicle and, in step 212, the analyzed photo is deleted from the external server

[0061] In step 213 the characteristics of the observing vehicle are associated with the data coming from the GNSS system and the sensors. In step 214, the previously associated data are analyzed. Subsequently, in step 215, information, for example, an advertisement is selected from a database containing the information and advertisements likely to be shown on the screens.

[0062] This information is then sent to the system present on the carrier vehicle and then in step 216 displayed on, for example, a screen attached to one of the sides preferentially on the rear side of the carrier vehicle.

[0063] In a third form of implementation of the method according to the invention in FIG. 3 a scheme 300 is illustrated in which in step 301 an image is acquired by means of a special device arranged on a carrier vehicle. In step 302 either a path A or a path B is selected through a random generator and by preset parameters. Along path A the captured image is, during step 303, stripped of personal identification elements as described in step 102 and then in step 304 the original photo, i.e., with data referring to the person or allowing an identification, is deleted.

[0064] If path B is chosen in step 302, the original image is immediately deleted in step 305 and replaced, in step 306, with a random image present in the land vehicle database.

[0065] At the end of step 304 or 306, step 307 is carried out, in which the GNSS data to identify the position of the carrier vehicle are associated with the image created in step 303 or with the image retrieved from the database in step 306. Then in step 308 the data from the other sensors are retrieved and associated with the previous ones, as previously described in the first embodiment of the method 106 and 107.

[0066] In step 309 the image is sent by means of a wireless system, for example by means of a data connection in the mobile telephony radio network and/or similar to an external server. Simultaneously in step 310 the image and data are locally erased.

[0067] In step 311 the image with data is processed on the external server, analyzed in step 312 and deleted in step 313.

[0068] In step 314, pre-selected information are sent, i.e. a series of information, that has been selected according to the analysis in step 312 according to the pre-set parameters.

[0069] In step 315, the data that has been retrieved from the sensors and from the GNSS is analyzed, these are associated, and in step 316, analyzed together with the pre-selected information that has been sent from the external server that has been selected and sent in step 309.

[0070] The information to be published in step 317 is selected locally on the device, in particular the advertising to be shown on at least one screen. In step 318 this selected information is displayed on at least one screen located on the carrier vehicle.

[0071] By means of this third method according to the invention no location-related data and/or other locally retrieved data are made accessible externally.

[0072] To implement one of the methods described above according to the invention, the system must comprise at least one device for acquiring images arranged on the carrier vehicle, a calculation unit for processing the image, a GNSS device for detecting the position of the observing vehicle installed on the carrier vehicle, a database for selecting an advertising image or information, a display device in particular a screen fixed to one side of the carrier vehicle preferably located at the rear of the carrier vehicle, and a power supply system. Advantageously, a series of sensors are arranged on the carrying vehicle for detecting the environmental and road conditions.

[0073] Finally, it is clear that additions, modifications or variations which are obvious to a person skilled in the art can be applied or added to the method and system described up to now without thereby departing from the scope of protection provided by the appended claims. In particular, the single steps of the method can be performed in different order.
