Abstract: An information processing method obtains location information indicating a location of a moving body at a time of detection of occurrence of a predetermined event that triggers recording of a photographic image acquired by photography using a photographic apparatus installed on the moving body. Then, the method determines whether or not the location indicated by the location information is a location where the driver is estimated to have visited a plurality of times, based on at least one of action history information indicating action history of a driver of the moving body and related-person information regarding a related person of the driver. Finally, the method controls to record the photographic image, according to the determination of whether or not the location indicated by the location information is a location where the driver is estimated to have visited a plurality of times.

Abstract: In an information collection method of the present disclosure, a processor of an information collection system acquires event sensor data and identification information from an on-vehicle terminal or a passenger terminal, the event sensor data being output, in response to an event trigger, from an on-vehicle sensor mounted on the on-vehicle terminal or a passenger sensor mounted on the passenger terminal, the identification information identifying an output source of the event sensor data, identifies the passenger terminal associated with the identification information when the identification information indicates the on-vehicle terminal, identifies the on-vehicle terminal associated with the identification information when the identification information indicates the passenger terminal, requests sensor data from the identified passenger terminal or on-vehicle terminal, acquires the sensor data from a request destination, and stores the event sensor data and the sensor data in association with each other in a

Abstract: A computer implemented information processing method includes acquiring a first photographed image that represents an inside portion of a vehicle, identifying a driver who drives the vehicle from the first photographed image, acquiring driver information that indicates at least one of an attribute of the identified driver and a driving history of the identified driver. Then the method determines whether or not the identified driver satisfies a condition of experienced driver using the driver information. Finally the method decides a threshold value that is used for detection of occurrence of an event to be a trigger of photographing or recording of a second photographed image which represents an outside portion of the vehicle based on a result of the determination.

Abstract: A contribution level determination method includes: obtaining, from a first storage device, records of annotation works for each of one or more units of target data for which the annotation works carried out by each of workers that use crowdsourcing have been completed; and calculating work contribution levels for each of worker IDs representing a different one of the workers, in accordance with a predetermined weighting rule stored in a second storage device, by referring to the records. In the calculating of the contribution levels, for each of the one or more units of target data, the work contribution level is calculated using a heavier weight for the worker ID representing a particular worker who carried out the annotation work initially than for the work contribution levels for the worker IDs representing the workers who carried out annotation works after the particular worker, in the order of the annotation works.

Abstract: Techniques of simplifying a process of performing an annotation process and constructing learning data by using CG data are provided. A learning data generation device generates scene data for generating learning data from scene data of CG data that include various models. In the generation, the models other than a specific object model are deleted from the scene data, the specific object model is made a specific color, and a specific object region of the specific object model is set. Then, the image for scene data and information of the specific object region are associated with each other and stored as the learning data in a second storage unit.

Abstract: An adherent detecting method for, by means of at least one computer, detecting a target adherent adhering to a translucent body that separates an imaging element and a photographing target from each other includes acquiring a photographed image that is generated by photographing via the translucent body with the imaging element. Next, the photographed image is inputted as input data into a recognition model for recognizing the presence or absence of an adherent to the translucent body in an image taken via the translucent body. Then, the presence or absence of the target adherent in the photographed image is detected by acquiring information outputted from the recognition model and indicating the presence or absence of an adherent in the photographed image.

Abstract: A moving body detecting method for, by means of at least one computer, detecting a target moving body that is a moving body which possibly constitutes an obstacle to running of a target vehicle includes acquiring a photographed image that is generated by photographing with a camera situated on board the target vehicle. Next, the photographed image is inputted as input data into a recognition model for recognizing a moving body in an image taken of the moving body, type information indicating a type of the moving body, and position information indicating that one of a plurality of positions including a sidewalk and a roadway in which the moving body is present. Then, the target moving body in the photographed image is detected by acquiring the type information and position information of the moving body in the photographed image as outputted from the recognition model.
