摘要:
A map creation apparatus includes an image receiver configured to receive images in time series while moving; a first calculator configured to extract an image area indicating an object from the images and calculate a coordinate of the object in a world coordinate system; a second calculator configured to track the object in the extracted image area with the images and calculate an optical flow of the object; an eliminator configured to calculate a difference in coordinate between vanishing points generated by the movement of the image receiver and the object based on the optical flow, and eliminate the image area of the object from the images when determining the object as a moving object based on the calculated difference; and a storage controller configured to store map information including the coordinate of the object, not eliminated by the moving object eliminator, in the world coordinate system.
摘要:
A reception apparatus for receiving data from a transmission apparatus includes a data receiver configured to receive a synchronization packet including clock information generated by the transmission apparatus and data from the transmission apparatus, a storage memory, storing the received data, a clock adjuster configured to correct a clock of the reception apparatus based on a deviation between a clock of the transmission apparatus and the clock of the reception apparatus by using the clock information generated by the transmission apparatus, a controller configured to control a clock correction amount of the clock adjuster based on a storage amount of data in the storage memory, and a data output circuit configured to retrieve the data from the storage memory to output the retrieved data in synchronization with the corrected clock.
摘要:
An information processing apparatus recognizes input data as character information formed by character strings each being in a predetermined unit based on information relating to a character string as a recognition target, and performs processing based on the recognized character information. The apparatus includes an input information receiver that receives input information capable of being processed as characters; an input information dividing unit that divides the received input information into character strings each being in a predetermined processing unit; a popularity level calculating unit that calculates a popularity level based on history of an appearance timing of each of the divided character strings, the popularity level indicating information relating to a usage frequency for a predetermined period of time up to a current time for each of the divided character strings; and an updating processor that updates the information relating to the character string based on the calculated popularity level.
