In-vehicle surrounding environment recognition device
First Claim
1. An in-vehicle surrounding environment recognition device, comprising:
- a photographic unit that photographs a road surface around a vehicle and acquires a photographic image;
an application execution unit that recognizes another vehicle that is traveling near the vehicle on the basis of the photographic image acquired by the photographic unit, and detects a relative speed of the other vehicle with respect to the vehicle;
a reflection determination unit that, on the basis of the photographic image, determines upon presence or absence of a reflection of a background object from the road surface;
a warning control unit that controls output of a warning signal on the basis of the result of recognition of the other vehicle by the application execution unit; and
a warning prevention adjustment unit that suppresses output of the warning signal on the basis of the relative speed of the other vehicle, if it has been determined by the reflection determination unit that there is the reflection of the background object from the road surface, and whereinthe warning prevention adjustment unit adjusts a level of suppression of output of the warning signal by changing a condition for the reflection determination unit to determine upon the presence or absence of the reflection of the background object from the road surface, according to the relative speed of the other vehicle.

10. An in-vehicle surrounding environment recognition device, comprising:
-
a photographic unit that photographs a road surface around a vehicle and acquires a photographic image; an application execution unit that recognizes another vehicle that is traveling near the vehicle on the basis of the photographic image acquired by the photographic unit; and a reflection determination unit that distinguishes a background region and a reflection region of the photographic image, and determines upon presence or absence of a reflection of a background object from the road surface on the basis of correlation between image characteristics of those regions, and wherein, if it has been determined by the reflection determination unit that the reflection of the background object from the road surface is present, recognition of the other vehicle by the application execution unit is suppressed.
