For example, the processor 10 is a CPU (Central Processing Unit), and executes each information processing by executing a program or the like stored in the storage 12 and expanded in the memory 11.

The memory 11 includes a main memory composed of a volatile storage device such as a DRAM (Dynamic Random Access Memory) and an auxiliary memory composed of a non-volatile storage device such as a flash memory or an HDD (Hard Disk Drive). .. The memory 11 is used as a work area or the like of the processor 10, and also stores a BIOS (Basic Input / Output System) executed when the management server 1 is started, various setting information, and the like.

The storage 12 stores various programs such as application programs. A database storing data used for each process may be built in the storage 22.

The transmission / reception unit 13 connects the management server 1 to the network. The transmission / reception unit 13 may be provided with a short-range communication interface of Bluetooth (registered trademark) and BLE (Bluetooth Low Energy). The transmission / reception unit receives a request from the corporate terminal and transmits the generated mission information to the user terminal.

The input / output unit 14 is an information input device such as a keyboard and a mouse, and an output device such as a display.

The bus 15 is commonly connected to each of the above elements and transmits, for example, an address signal, a data signal, and various control signals.

<User terminal 2>

The user terminal 2 constitutes a part of the information providing system by executing information processing via communication with the management server 1.

FIG. 3 is a diagram showing an example of a functional block diagram of the user terminal 2. The configuration shown is an example, and functions other than these may be added.

The user terminal 2 includes, for example, a mobile communication device such as a smartphone or a tablet terminal, but may be a general-purpose computer such as a personal computer.

As shown, the user terminal 2 includes at least a processor 20, a memory 21, a storage 22, a transmission / reception unit 23, an input / output unit 24, and the like, which are electrically connected to each other through a bus 25. Since these functions are the same as those of the management server 1 described above, detailed description thereof will be omitted here.

The user terminal 2 according to the present embodiment is a so-called wearable terminal (AR goggles), and is worn on the user's head.

The above-mentioned input / output unit 24 includes at least a camera unit 242 as an input unit and an HMD (Head Mount Display) 241 as an output unit.

The camera unit has a recording function that covers an area substantially similar to the user's field of view. The HMD242 is, for example, a glass type, and can display various information through the lens.

As shown in FIG. 4, the functional block includes a determination unit, a processing unit, and an acquisition unit. These functions will be described later.
<Data>
As shown in FIG. 4, the mission information includes at least determination condition information, processing processing information, and reward information. These are generated by the management server 1 based on a request from the corporate terminal, but mission information may be generated by the corporate terminal as needed.

The judgment condition information is information acquired by the acquisition unit of the user terminal 2 (position information, camera unit, time, temperature, atmospheric pressure, operation status, and other information directly or indirectly acquired by the sensor group provided in the user terminal). Contains information (functional package) necessary for determining (recognizing) whether or not a predetermined determination condition is satisfied. There may be a plurality of pieces of information to be acquired.

The processing processing information is information (functional package) for processing the information obtained from the acquisition unit when the above-mentioned determination conditions are satisfied.

The determination condition information and processing processing information described above include, for example, a logic for extracting an object from an image (video) acquired by a camera unit or the like. The logic can employ various techniques necessary for extracting an object, such as an image recognition model and a voice recognition model (when the target is voice).

For example, in the case of mission information with the purpose of "information on the location of empty cans that have fallen in the city", the judgment condition information is such that the camera unit (acquisition unit) constantly acquires an image and whether or not there is an empty can in the image. It is the information for making a determination (recognition), and the processing processing information is the instruction information for acquiring the position information of the user terminal when it is determined that the empty can has fallen.

Also, in the case of mission information with the purpose of "information on the license plate of a vehicle abandoned in the city", the judgment condition information is determined by having the camera unit (acquisition unit) constantly acquire an image and whether or not there is an abandoned vehicle in the image. The processing information is information for cutting out the license plate from the abandoned vehicle and information for recognizing the characters of the license plate and extracting it as text information.

<Processing flow>
Subsequently, the processing flow of the information providing system according to the present embodiment will be described with reference to FIGS. 1, 4 and 5. As shown in FIG. 1, the management server 1 according to the present embodiment roughly provides a platform service for connecting a company (corporate terminal) and a user (user terminal). Note that FIG. 1 is a schematic diagram, and the management server 1 does not have to be one, and each function may be distributed to a plurality of terminals.

The company (company A to company C) makes a request to the management server 1. Requests include, for example, "I want to know information about empty cans left in the city", "I want to collect information on illegal parking", "I want to know the products purchased by users who have entered convenience stores", etc. It relates to the user's visual information obtained by using the camera unit.

At this time, the company sets a reward for the information that it wants to know or collect. For example, "If you find one empty can, it costs 0.1 yen", "If you find one abandoned vehicle, it costs 0.7 yen", "If you provide merchandise information purchased at a convenience store, it costs 8 yen". The method of setting the reward may be set for each number / number of units, set according to a group number, or set according to the time searched for.

The management server 1 transmits the request as the above-mentioned mission information to the user terminal, and causes the user terminal to perform a predetermined process. The mission information includes, for example, items such as "empty can / 0.1 yen", "abandoned vehicle / 0.7 yen", and "visual field information in convenience store / 8 yen".

Each of the user P1 to the user Pn has a terminal capable of operating the above-mentioned HMD, and the camera unit mounted on each HMD can acquire the information of the field of view V1 to the field of view Vn.

The user who receives the mission information can select whether or not to participate in the mission specified by the mission information. When the user participates in the mission, the participation information is transmitted to the management server 1, and the identification information of the mission and the identification information of the user (user terminal) are managed in association with each other.

<Processing on the user terminal 2 side>
More specifically, as shown in FIG. 4, the receiving unit of the user terminal 2 receives the mission information transmitted from the management server 1. At this time, of the mission information, only the determination condition information and the processing processing information may be received as the mission information.

The mission information is input to the control unit. Hereinafter, each process performed when the mission information regarding the above-mentioned "information on the location of empty cans left in the city" and "information on the license plate of the vehicle left in the city" is received will be described.

When receiving "information on the location of empty cans that have fallen in the city", the judgment unit enables the function of the camera unit based on the judgment condition information to constantly acquire the image, and whether or not there is an empty can in the image. Is determined by image recognition technology. The processing unit acquires position information from GPS based on the determination result. The position information is output to the transmission unit as processing information and transmitted to the management server 1.

In addition to the above-mentioned functions, the processing unit further trims only the empty can part of the image, applies a mosaic to the part other than the empty can, and extracts only the number of empty cans from the image to obtain numerical data (others). It may be converted into a format) or a process of extracting a brand of an empty can may be performed. Further, it may be transmitted together with other information obtained by the user terminal such as time information.

If necessary, it may be output to the transmission unit without any processing. In this case, from the user side, since the amount of information provided to the company increases, the reward may be increased.

Subsequently, when "information on the license plate of a vehicle left in the city" is received, the judgment unit enables the function of the camera unit based on the judgment condition information to constantly acquire the image, and also in the image. Whether or not there is a stopped vehicle is determined by image recognition technology. The processing section extracts only the license plate part from the image. The extracted information is output to the transmission unit and transmitted to the management server 1 as processing information.

In addition to the above-mentioned functions, the processing unit further trims only the license plate part of the image, applies a mosaic to the part other than the license plate, and extracts only the license plate text from the image and texts. It may be converted into data or information on the vehicle type of the vehicle may be extracted. Further, in addition to these information, position information may be acquired from GPS.

The image recognition model in the present embodiment is input to the image to be processed. Next, the area to be recognized is extracted from the input image. For example, when the object to be recognized is an object (person) related to the object information, the areas judged to be those are extracted from the supplied image. A plurality of regions may be extracted from one image.

Then, the feature amount is extracted from the extracted area (image of the area). The content of the extracted features is specified by the recognition process.

As the recognition process (image recognition model), for example, a method suitable for the recognition target such as HMM (Hidden Markov Model) or SVM (Support Vector Machine) is used. Then, the feature amount suitable for the method used is extracted, and the parameters are retained.

<Processing on the management server side 1>
As shown in FIG. 5, the data transmitted from the user terminal 2 is received by the receiving unit of the management server 1. The received data is input to the control unit and the reward is calculated in the reward calculation unit.

The reward is calculated according to the evaluation conditions. Evaluation conditions are performed from various viewpoints. For example, if the information transmitted from the user terminal is not the information to be provided by the mission information, it will be 0 (that is, if a processing error or the like has occurred on the user terminal side, or an unauthorized operation has been performed. Case etc.). Further, even if the information satisfies the target information, if there is another user who has already transmitted the same information, the reward is low because the information is not new as data.

In this way, the evaluation conditions are defined from the viewpoint of eligibility as target information and usefulness of data. The viewpoint of evaluation may be other than this.

The reward calculation unit corrects and determines the reward to be given to the user based on the above evaluation conditions. The compensation can be adjusted by multiplying by a coefficient according to the standard amount or by increasing or decreasing the constant, but the method is not limited to this.

The fixed reward is notified to the user terminal 2.

<Example>
FIG. 6 is a field of view (outside world information) that the user sees through the HMD. For example, as shown in the figure, the cursor may be placed on a detection target related to the mission information in which the user is participating to notify the user.

In the figure, a vehicle stopped on the road is recognized as an abandoned vehicle, and a cursor is displayed on the license plate of the vehicle. In this case, the information of the license plate is transmitted to the management server 1.

Similarly, in the figure, an empty can that has been thrown away on the road is recognized, and a cursor is displayed on the empty can. In this case, the information that the empty can was on the road is transmitted to the management server 1.

The above-mentioned processing information may be transmitted sequentially, or may be performed after a certain amount of data has been collected.

As described above, the management server 1 grants the set reward to the user (user terminal) according to the analysis result transmitted from the user terminal.

FIG. 7 is an image diagram illustrating the types of information transmitted from the user terminal 2 to the management server 1. As described above, not all the information acquired by the camera unit is transmitted to the management server 1. In other words, only the information related to the detection target included in the mission information is extracted and transmitted to the management server 1 from the outside world information.

For example, the following three patterns can be considered as the information transmitted from the user terminal to the management server 1. In the case of an empty can, only the "presence / absence" information of the detection target is transmitted to the management server 1 (1). Further, in the case of an abandoned vehicle, when the image data of only the license plate part is transmitted to the management server 1 (2), the character information is further analyzed from the license plate (that is, the information of (2) is processed). ) It may be sent to the management server 1 (3). In addition, information obtained from other sensor groups may be added and transmitted (4).

As described above, in the present embodiment, of the information acquired by the camera unit of the user terminal, only the portion necessary for the mission information is transmitted to the extracted management server 1, so that the data is lightweight. The following effects can be obtained in addition to the conversion.

That is, according to the present embodiment, since it is not necessary to transmit so-called raw data to the management server, it is possible to prevent security, leakage of personal information, and unnecessary disclosure.

Further, by using the present invention, the user can provide only necessary information to the management server while constantly activating the camera unit. That is, it is possible to save the trouble of activating the camera unit only when the detection target is photographed by the camera unit (when an abandoned vehicle is found, an empty can is found, etc.).

In addition, it is possible to obtain multiple rewards by receiving multiple mission information, and it is possible to encourage active participation in this system. As a result, it is possible to improve the efficiency of providing information to the company that requested the mission information.

The reward information may be changed according to the amount and content of the information received from the user terminal. Further, the user side may control the amount and content of the information transmitted to the management server 1.

The above-described embodiments are merely examples for facilitating the understanding of the present invention, and are not intended to limit the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.

As shown in FIG. 7, the present invention can be applied not only to an HMD, but also to, for example, an unmanned aerial vehicle equipped with a camera unit (drone, etc.), an automobile having an automatic driving function, and the like. In this case, an analysis unit for analyzing the detection target of the mission information may be provided on the unmanned aircraft or the automobile side.

Further, the above-mentioned mission information is not limited to the example, and may be, for example, the provision of information on a specific person, object, phenomenon, or the like, or information on the user's home.
