Next, an example of processing by the data processing system 10 according to the first embodiment will be described.

[0028] (Example 1) A system according to an embodiment of the present invention analyzes images of road signs captured by an onboard camera and provides audio warnings to the driver. In this system, the onboard camera captures road signs, AI analyzes the images, recognizes the content of the signs, and provides audio warnings to the driver. For example, the onboard camera captures a speed limit sign, the AI ​​recognizes the speed limit, and provides an audio warning to the driver, saying, "The speed limit is 50 km / h." Furthermore, when a stop sign is recognized, the AI ​​provides an audio warning, saying, "Please stop." This complements areas that cannot be fully supported by car navigation systems and supports safe driving. This complements areas that cannot be fully supported by car navigation systems and supports safe driving. For example, the system can recognize road signs outside the range of navigation systems based on map data and provide audio warnings to the driver. This supports safe driving and contributes to preventing traffic accidents.

[0029] A road sign recognition system according to an embodiment includes a photographing unit, a transmission unit, an analysis unit, a receiving unit, and a notification unit. The photographing unit photographs road signs using an onboard camera. For example, the photographing unit is installed in front of a vehicle and automatically photographs signs while the vehicle is traveling. The transmission unit transmits the image photographed by the photographing unit. For example, the transmission unit can transmit the image using a communication method such as Wi-Fi or Bluetooth (registered trademark). The analysis unit analyzes the image transmitted by the transmission unit. The analysis unit recognizes the content of the sign using image recognition technology with AI. For example, the analysis unit can recognize speed limit signs and identify the speed limit using deep learning. The analysis unit can also recognize stop signs and identify the stopping position indicated by the sign. The receiving unit receives the results of the analysis performed by the analysis unit. For example, the receiving unit can receive the analysis results using a communication method such as Wi-Fi or Bluetooth. The notification unit issues a voice alert based on the results received by the receiving unit. The notification unit issues a voice alert using AI and voice synthesis technology. For example, when the notification unit recognizes a speed limit sign, it notifies the driver by voice, saying, "The speed limit is 50 km / h." When the notification unit recognizes a stop sign, it notifies the driver by voice, saying, "Please stop." In this way, the road sign recognition system according to the embodiment can analyze the image of the road sign read by the on-board camera and alert the driver by voice.

[0030] The analysis unit can recognize the content of the sign using image recognition technology. Image recognition technology includes, for example, deep learning and pattern recognition. The analysis unit can recognize the content of the sign using, for example, deep learning. For example, the analysis unit can recognize a speed limit sign and identify the speed limit. The analysis unit can also recognize a stop sign and identify the stopping position indicated by the sign. Furthermore, the analysis unit can recognize the content of the sign using pattern recognition. For example, the analysis unit recognizes the content based on the shape and color of the sign. As a result, the content of the sign can be accurately recognized using image recognition technology.

[0031] The notification unit can issue a warning using a voice synthesis technology. Examples of voice synthesis technology include text-to-speech synthesis and voice sample-based synthesis. The notification unit issues a warning using, for example, text-to-speech synthesis. For example, when the notification unit recognizes a speed limit sign, it issues a voice warning saying, "The speed limit is 50 km / h."

Furthermore, the notification unit can also issue a warning using voice sample-based synthesis. For example, the notification unit issues a warning using a pre-recorded voice sample. In this way, by using voice synthesis technology, it is possible to effectively warn the driver.

[0032] The camera unit is installed in front of the vehicle and can automatically photograph signs while the vehicle is traveling. The front of the vehicle includes, for example, the top of the windshield and near the bumper. The camera unit is installed, for example, in the top of the windshield and can automatically photograph signs while the vehicle is traveling. For example, the camera unit photographs signs that contain important driving information, such as speed limit signs and stop signs. The camera unit can also be installed near the bumper and can automatically photograph signs while the vehicle is traveling. This reduces the burden on the driver by allowing the camera unit installed in front of the vehicle to automatically photograph signs.

[0033] The analysis unit can recognize speed limit signs and identify the speed limit. Speed ​​limit signs include, for example, speed limits on general roads and speed limits on expressways. The analysis unit can recognize, for example, speed limit signs on general roads and identify the speed limit. For example, the analysis unit can identify that the speed limit is 50 km / h. The analysis unit can also recognize speed limit signs on expressways and identify the speed limit. For example, the analysis unit can identify that the speed limit is 100 km / h. In this way, by recognizing speed limit signs and identifying the speed limit, it is possible to provide the driver with appropriate speed information.

[0034] The analysis unit can recognize a stop sign and identify the stop position indicated by the sign. Stop signs include, for example, stop signs at intersections and stop signs at railroad crossings.

[0035] The image capturing unit can automatically adjust a filter to accommodate different weather conditions. Different weather conditions include, for example, rain, snow, and fog. For example, the image capturing unit automatically applies a waterproof filter when it is raining to maintain the clarity of the captured image. For example, the image capturing unit applies a filter that removes raindrops to improve the visibility of signs. The image capturing unit can also automatically apply a filter that suppresses snow reflections on snowy days to improve the visibility of signs.

The image capturing unit can also automatically apply a filter that penetrates fog when it is foggy to clearly capture signs. For example, the image capturing unit applies a filter that penetrates fog to ensure the visibility of signs. In this way, the clarity of the captured image can be maintained by automatically adjusting a filter that corresponds to different weather conditions.

[0036] The image capturing unit can also use an infrared camera to accurately capture signs even in low-light environments such as at night or inside a tunnel. Low-light environments include, for example, at night or inside a tunnel. The image capturing unit, for example, automatically activates the infrared camera when driving at night to clearly capture signs. For example, the image capturing unit uses the infrared camera to capture signs at night to improve visibility. The image capturing unit can also use the infrared camera when driving inside a tunnel to ensure sign visibility. For example, the image capturing unit uses the infrared camera in the low-light environment of a tunnel to clearly capture signs. The image capturing unit can also use the infrared camera when driving in a low-light environment to accurately capture signs. For example, the image capturing unit uses the infrared camera to capture signs in a low-light environment to improve visibility. This allows accurate capture of signs even in low-light environments to provide appropriate information to the driver.

[0037] The camera unit adjusts the capture frequency according to the vehicle speed, capturing images more frequently when the vehicle is traveling at high speeds. Examples of vehicle speeds include 30 km / h and 100 km / h. The camera unit increases the capture frequency when the vehicle is traveling on a highway to ensure that important signs are not overlooked. For example, the camera unit detects the vehicle's speed using a sensor and increases the capture frequency as the speed increases. The camera unit can also return the capture frequency to normal when traveling in urban areas and capture only necessary information. For example, the camera unit reduces the capture frequency when the vehicle is traveling at a low speed. The camera unit can also reduce the capture frequency during traffic jams to reduce the burden on the driver. For example, the camera unit minimizes the capture frequency when the vehicle is traveling at a very low speed. This allows the camera unit to adjust the capture frequency according to the vehicle's speed to ensure that important signs are not overlooked.

[0038] The image capturing unit can capture signs in all directions using multiple cameras that cover 360 degrees around the vehicle. Omnidirectional includes, for example, the front, sides, and rear. The image capturing unit can be installed with multiple cameras to capture signs not only in front but also on the sides and rear. For example, the image capturing unit can be installed with a front camera in front of the vehicle, side cameras on the sides, and a rear camera on the rear. The image capturing unit can also capture signs at intersections in all directions and provide necessary information to the driver. For example, the image capturing unit can be installed with cameras that cover intersections in all directions and capture signs. The image capturing unit can also capture signs in parking lots in all directions to provide parking support.

For example, if the driver is nervous, the notification unit can notify the driver in a calm voice, "Please drive relaxed." Also, if the driver is relaxed, the notification unit can notify the driver in a normal voice, "Pay attention to the next sign." Furthermore, if the driver is tired, the notification unit can notify the driver in a gentle voice, "We recommend that you take a break." In this way, the content and timing of notifications can be adjusted according to the driver's emotions, thereby supporting the driver's safe driving.

[0131] The camera unit can automatically adjust the image resolution according to the vehicle's speed and driving environment. For example, when driving on a highway, the camera unit captures signs at high resolution to obtain detailed information. When driving in an urban area, the camera unit can capture signs at normal resolution to obtain the necessary information. Furthermore, in bad weather, the camera unit can switch to high-sensitivity mode to improve the visibility of signs. This allows the camera unit to adjust the image resolution according to the vehicle's speed and driving environment, making it possible to accurately obtain sign information.

[0132] The analysis unit not only recognizes the content of the sign, but also analyzes the surrounding environment of the sign's location and can provide appropriate driving advice to the driver. For example, the analysis unit can analyze the condition of buildings and roads around the sign and provide advice to the driver such as, "Be careful, the road continues to be narrow ahead." The analysis unit can also analyze the movement of pedestrians around the sign and notify the driver, "Be careful, there are many pedestrians ahead." Furthermore, the analysis unit can analyze the movement of other vehicles around the sign and provide advice to the driver such as, "Be careful, traffic congestion is expected ahead." This can support safe driving by providing driving advice that takes into account not only the content of the sign but also the surrounding environment.

[0133] The processing flow of the second embodiment will be briefly explained below.

[0134] Step 1: The camera unit captures road signs with an in-vehicle camera. For example, the camera unit is installed in front of the vehicle and automatically captures road signs while driving. Step 2: The transmitting unit transmits the image captured by the capturing unit. For example, the transmitting unit can transmit the image using a communication means such as Wi-Fi or Bluetooth. Step 3: The analysis unit analyzes the image sent by the transmission unit. The analysis unit uses AI and image recognition technology to recognize the content of the sign. For example, the analysis unit can use deep learning to recognize speed limit signs and identify the speed limit. The analysis unit can also recognize stop signs and identify the stopping position indicated by the sign. Step 4: The receiving unit receives the analysis result obtained by the analyzing unit. For example, the receiving unit can receive the analysis result using a communication means such as Wi-Fi or Bluetooth. Step 5: The notification unit issues a voice alert based on the results received by the receiving unit. The notification unit uses AI and voice synthesis technology to issue the alert. For example, if the notification unit recognizes a speed limit sign, it will issue a voice alert saying, "The speed limit is 50 km / h." If it recognizes a stop sign, it will issue a voice alert saying, "Please stop."

[0135] The specific processing unit 290 transmits the result of the specific processing to the smart device 14. In the smart device 14, the control unit 46A causes the output device 40 to output the result of the specific processing. The microphone 38B acquires audio indicating a user input regarding the result of the specific processing. The control unit 46A transmits audio data indicating the user input acquired by the microphone 38B to the data processing device 12. In the data processing device 12, the specific processing unit 290 acquires the audio data.

The AI ​​may also be an AI agent. When the processes of each of the above-mentioned parts are performed by AI, the processes may be performed in part or entirely by AI, but are not limited to these examples. The processes performed by AI, including the generative AI, may be replaced with rule-based processes.

[0188] The emotion identification model 59 as an emotion engine may determine the user's emotion according to a specific mapping. Specifically, the emotion identification model 59 may determine the user's emotion according to an emotion map (see FIG. 9), which is a specific mapping. Similarly, the emotion identification model 59 may determine the robot's emotion, and the identification processing unit 290 may perform identification processing using the robot's emotion.

[0189] FIG. 9 illustrates an emotion map 400 on which multiple emotions are mapped. In the emotion map 400, emotions are arranged in concentric circles radiating from the center. Emotions closer to the center of the concentric circles are more primitive. Emotions representing states and behaviors arising from a state of mind are arranged on the outer edges of the concentric circles. The concept of emotion encompasses both emotions and mental states. Emotions generally generated from reactions occurring in the brain are arranged on the left side of the concentric circles. Emotions generally induced by situational judgment are arranged on the right side of the concentric circles. Emotions generally generated from reactions occurring in the brain and induced by situational judgment are arranged on the upper and lower sides of the concentric circles. Furthermore, the emotion of "pleasure" is arranged on the upper side of the concentric circles, and the emotion of "discomfort" is arranged on the lower side. In this way, in the emotion map 400, multiple emotions are mapped based on the structure by which emotions are generated, and emotions that tend to occur simultaneously are mapped close to each other.

[0190] These emotions are distributed in the 3 o'clock direction on emotion map 400, and typically fluctuate between relief and anxiety. In the right half of emotion map 400, situational awareness dominates over internal sensations, resulting in a sense of calm.

[0191] The inside of emotion map 400 represents what is going on in the mind, and the outside of emotion map 400 represents behavior, so the further you go outside emotion map 400, the more visible the emotions become (the more they are expressed in behavior).

[0192] Human emotions are based on various balances, such as posture and blood sugar levels. When these balances deviate from the ideal, a state of discomfort is expressed, and when they approach the ideal, a state of pleasure is expressed. Emotions can also be created for robots, cars, and motorcycles, based on various balances, such as posture and remaining battery life. When these balances deviate from the ideal, a state of discomfort is expressed, and when they approach the ideal, a state of pleasure is expressed. An emotion map can be generated, for example, based on Dr. Mitsuyoshi's emotion map (Research on speech emotion recognition and brain physiological signal analysis systems for emotions, Tokushima University, doctoral dissertation: https: / / ci.nii.ac.jp / naid / 500000375379). The left half of the emotion map lists emotions belonging to the area called "reaction," where sensation is dominant. The right half of the emotion map lists emotions belonging to the area called "situation," where situational awareness is dominant.

[0193] The emotion map defines two emotions that promote learning. One is a negative emotion on the situation side, around the middle of "repentance" or "reflection." In other words, this occurs when the robot experiences negative emotions such as "I never want to feel this way again" or "I don't want to be scolded again." The other is a positive emotion on the response side, around "desire." In other words, this occurs when the robot experiences positive feelings such as "I want more" or "I want to know more."

[0194] The emotion identification model 59 inputs user input into a pre-trained neural network, obtains emotion values ​​indicating each emotion shown in the emotion map 400, and determines the user's emotion. This neural network is pre-trained based on multiple pieces of training data that are combinations of user input and emotion values ​​indicating each emotion shown in the emotion map 400. Furthermore, this neural network is trained so that emotions that are located close to each other have similar values, as in the emotion map 900 shown in FIG. 10. FIG. 10 shows an example in which multiple emotions, "relieved," "calm," and "reassuring," have similar emotion values.

[0195] In the above embodiment, an example was given in which a specific process is performed by one computer 22, but the technology disclosed herein is not limited to this, and distributed processing of the specific process may be performed by multiple computers including computer 22.

[0196] In the above embodiment, an example in which the specific processing program 56 is stored in the storage 32 has been described, but the technology of the present disclosure is not limited to this. For example, the specific processing program 56 may be stored in a portable, computer-readable, non-transitory storage medium such as a USB (Universal Serial Bus) memory. The specific processing program 56 stored in the non-transitory storage medium is installed in the computer 22 of the data processing device 12. The processor 28 executes the specific processing in accordance with the specific processing program 56.

[0197] Alternatively, the specific processing program 56 may be stored in a storage device such as a server connected to the data processing device 12 via the network 54, and the specific processing program 56 may be downloaded and installed on the computer 22 in response to a request from the data processing device 12.

[0198] It is not necessary to store all of the specific processing program 56 in a storage device such as a server connected to the data processing device 12 via the network 54, or to store all of the specific processing program 56 in the storage 32; only a portion of the specific processing program 56 may be stored.

[0199] The hardware resource for executing a specific process can be any of the following types of processors: A processor, for example, is a CPU, which is a general-purpose processor that functions as a hardware resource for executing a specific process by executing software, i.e., a program. A processor also includes a dedicated electrical circuit, such as an FPGA (Field-Programmable Gate Array), a PLD (Programmable Logic Device), or an ASIC (Application Specific Integrated Circuit), which is a processor with a circuit configuration designed specifically for executing a specific process. Each processor has built-in or connected memory, and each processor uses the memory to execute the specific process.

[0200] The hardware resource that executes the specific process may be configured with one of these various processors, or may be configured with a combination of two or more processors of the same or different types (for example, a combination of multiple FPGAs, or a combination of a CPU and an FPGA). Also, the hardware resource that executes the specific process may be a single processor.

[0201] As an example of a system configured with a single processor, first, one processor is configured by combining one or more CPUs and software, and this processor functions as a hardware resource that executes a specific process. Second, there is a system that uses a processor that realizes the functions of an entire system including multiple hardware resources that execute a specific process on a single IC chip, as typified by SoC (System-on-a-chip). In this way, a specific process is realized using one or more of the above-mentioned various processors as hardware resources.

[0202] Furthermore, the hardware structure of these various processors can be, more specifically, an electric circuit that combines circuit elements such as semiconductor devices. The specific processing described above is merely an example. Therefore, it goes without saying that unnecessary steps may be deleted, new steps may be added, or the processing order may be rearranged, without departing from the spirit of the invention.

[0203] In the above example, the first to fourth embodiments have been described separately, but some or all of these embodiments may be combined. The smart device 14, smart glasses 214, headset terminal 314, and robot 414 are merely examples, and they may be combined, or other devices may be used. In the above example, the first and second embodiments have been described separately, but they may be combined.

[0204] The above-described description and illustrations are a detailed explanation of the parts related to the technology of the present disclosure and are merely an example of the technology of the present disclosure. For example, the above description of the configuration, functions, actions, and effects is an explanation of an example of the configuration, functions, actions, and effects of the parts related to the technology of the present disclosure. Therefore, it goes without saying that unnecessary parts may be deleted, new elements may be added, or replacements may be made to the above-described description and illustrations within the scope of the gist of the technology of the present disclosure. Furthermore, in order to avoid confusion and to facilitate understanding of the parts related to the technology of the present disclosure, the above-described description and illustrations omit explanations of common technical knowledge that do not require particular explanation to enable the implementation of the technology of the present disclosure.
