VEHICLE COLLISION RISK PREDICTION APPARATUS
First Claim
1. A vehicle risk prediction apparatus comprising:
- a first imaging unit that detects an electromagnetic wave of a wavelength ranging from a millimeter wave to a submillimeter wave to output a first image;
a first detection unit that processes the first image output from the first imaging unit to detect a given object; and
a risk prediction unit that outputs detection result of the given object detected by the first detection unit,wherein the first imaging unit includes;
a transmit antenna unit that radiates the electromagnetic wave of the wavelength ranging from the millimeter wave to the submillimeter wave;
a receive antenna array unit that has a plurality of receive antenna units arranged two-dimensionally, and receives a reflected wave of the electromagnetic wave radiated by the transmit antenna unit from the given object; and
a signal processing unit that measures a time from radiation of the electromagnetic wave by the transmit antenna unit to reception of the reflected wave by the receive antenna array unit according to the number of read frames by the receive antenna array, and calculates both or any one of a distance from the subject vehicle to the given object, and a relative speed between the subject speed and the given object.
