Abstract: There is provided a detection device that includes: a position estimator that estimates a candidate position of a crosswalk in a movement direction of a vehicle and estimates a length of the crosswalk and an intersecting angle between the crosswalk and a roadway using the candidate position; a corrector that corrects the numbers of periods and widths of two basis functions based on the estimated length of the crosswalk and the estimated intersecting angle, the two basis functions corresponding to intervals of white lines of the crosswalk and are orthogonal to each other; and a crosswalk detector that detects whether or not the crosswalk is present using both image data which include the candidate position and the two corrected basis functions.

Abstract: A determination device includes: route detection circuitry which detects, a first continuous body as a first part of a one or more first direction distance information with respect to a first object, and a second continuous body as a second part of the one or more first direction distance information with respect to a second object, in a first direction along a first route on which the moving body moves, and a third continuous body as the second part, in a second direction; route determination circuitry which determines presence or absence of a second route along the third continuous body.

Abstract: A transmission system is provided with a pulse sequence generator that generates a pulse sequence including Golay code or Spano code, a π/2-BPSK modulator that applies π/2-BPSK modulation to the pulse sequence generated by the pulse sequence generator, and a phase rotator that provides phase rotation for every pulse for output of the π/2-BPSK modulator and a reception system is provided with a phase rotator that provides a phase opposite to a phase provided by the phase rotator of the transmission system and a correlator that performs correlation calculation for output of the phase rotator, based on the output of the π/2-BPSK modulator.
