Generally, an information processing device according to one embodiment includes storage, a receiver, a detector, an extractor, and a position specifier. The storage stores therein, imaging positional information indicating, identification information on a landmark set, and registration landmark information, in association with one another. The receiver receives a captured image for position specification from an onboard device. The extractor extracts imaging landmark information serving as information on a detected landmark from the captured image for position specification. The position specifier specifies the position indicated by the imaging positional information associated with the identification information on the landmark set including the registration landmark information similar to the imaging landmark information as the position of a vehicle at time when the captured image for position specification is taken.

Information processing device and information processing system

According to an embodiment, a client includes a street information collection unit for collecting street information near an arrangement place, a provision determination unit for determining whether the street information collected by the street information collection unit is information required to be provided to the server, and a first transmission unit for transmitting the street information, which is determined to be required to be provided by determination of the provision determination unit, to the server, with client identification information for identifying the client.

According to one embodiment, in general, an information processing apparatus includes one or more processors. The one or more processors receive from an onboard device of a probe vehicle an image showing a vehicle group of one or more vehicles stopping on the same lane, imaging time of the image, and a position of the probe vehicle at the imaging time. The one or more processors select vehicle groups according to the imaging time and an imaging position. The one or more processors identify the selected vehicle groups as a vehicle queue. The one or more processors calculate a stopping vehicle-queue evaluation value. The one or more processors calculate a parking vehicle-queue evaluation value. The one or more processors determine whether the identified vehicle queue is the stopping vehicle queue or the parking vehicle queue.

According to one embodiment, generally, an information processing apparatus includes a vehicle detector, a stopped-vehicle evaluator, a parked-vehicle evaluator, and a determiner. The vehicle detector detects a vehicle from a captured image by an imaging device mounted in a probe vehicle. The stopped-vehicle evaluator calculates a stopped-vehicle evaluation value based on one or more stopped-vehicle conditions. The parked-vehicle evaluator calculates a parked-vehicle evaluation value based on one or more parked-vehicle conditions. The determiner determines whether the vehicle is stopped or parked based on both the evaluation values.

In general, according to one embodiment, an image distribution device of the embodiment includes a receiver, a compressor, a request acceptor, a determiner, and a distributor. The receiver receives data captured by an imaging device of an in-vehicle device mounted in a vehicle. The compressor compresses the captured data of after elapse of a certain time to generate compressed captured data. The request acceptor accepts a distribution request to specify a desired time from an information processing device. The determiner determines whether the desired time is a past time within a certain time from a present time. The distributor distributes, when the desired time is the past time within the certain time from a present time, the captured data to the information processing device, and distributes, when the desired time is a past time prior to the certain time, the compressed captured data to the information processing device.

According to one embodiment, a visible-light communication apparatus includes an image input unit, a calculation unit, a preamble detection unit, a bit train detection unit, and a reception unit. The image input unit is configured to input image data generated by photographing a source of visible light carrying data. The calculation unit is configured to generate, from the image data, luminance data about an image at a designated position. The preamble detection unit is configured to detect a preamble at the head of the data, on the basis of the luminance data. The bit train detection unit is configured to detect the data bit train from the image data, in accordance with the preamble. The reception unit is configured to reproduce the data from the data bit train.

Method and apparatus for visible light communication with image processing

According to one embodiment, a system is disclosed, which uses road parameters defining the road network and model parameters used as initial-value parameters, thereby performing traffic simulation by the microsimulation method. The system includes a traffic simulator and a display controller. The traffic simulator performs traffic simulation to predict a traffic condition on an object road of a road network. The display controller controls a display unit, displaying the result of the simulation. More precisely, the display controller displays a dynamic image showing the traffic condition of vehicles running on the road network, on the screen of the display unit, and changes the image in terms of pattern, in accordance with a display instruction.
