Abstract: An external environment recognition device includes: a road surface height estimation unit that estimates a height of a road surface on which an object is positioned in an image captured by a monocular camera installed in a vehicle; a road surface height reliability estimation unit that calculates reliability of a height of the road surface estimated by the road surface height estimation unit; and an object distance information estimation unit that estimates a distance to the object in accordance with the reliability calculated by the road surface height reliability estimation unit, in which the road surface height reliability estimation unit calculates the reliability based on a determination result as to whether the road surface is same as a grounding contact surface of the vehicle.

Abstract: An object distance detecting device includes: three imaging sections 101-1, 101-2, and 101-3 which image a same target object; a target object region specifying section 102 which specifies a region, in which the target object exists, on the basis of an image acquired from at least one of the imaging sections; an image selection section 103 which selects one base line direction among a plurality of base line directions defined by any two imaging sections among the imaging sections on the basis of an image of the region specified by the target object region specifying section 102, and selects an image of the region acquired from each of the two imaging sections defining the selected base line direction; and a distance detection section 104 which detects a distance to the target object existing in the region on the basis of the image selected by the image selection section.

Abstract: Provided is a signal processing device with which, even when detection objects differ among a plurality of sensors, it is possible to correctly obtain the relationship between a non-shared detection object and a detection object that is shared after fusion.
The present invention: stores a first positional relationship (for example, inside and outside a host vehicle lane) between a first object (for example, a vehicle ahead) recognized on the basis of an image captured by an imaging device 301, and a second object (for example, a white line); obtains the position of the first object on the basis of information about the first object recognized on the basis of information obtained from a sensor differing from the imaging device 301, and of information about the first object recognized on the basis of the image captured by the imaging device 301; obtains a second positional relationship (for example, inside and outside the host vehicle lane) between the obtained first object, and the second object recognized on the basis of the image captured by the imaging device 301; and compares the first positional relationship and the second positional relationship to determine a final positional relationship of the first object and the second object.

Abstract: Provided are an image processing apparatus and an image processing system capable of performing control in a state where redundancy is secured even when an imaging device itself has failed or is malfunctioning. The image processing apparatus 3 recognizes a recognition target based on image data obtained by imaging an outside world using a first imaging device 2a and a second imaging device 2b installed to be spaced apart from the first imaging device 2a in a vertical direction from an interior of a vehicle via a window glass 6, and includes: a first image processing unit 3a that recognizes a first recognition target based on image data of the first imaging device 2a; and a second image processing unit 3b that recognizes a second recognition target different from the first recognition target based on image data of the first imaging device 2a and the second imaging device 2b. When a predetermined condition is satisfied, the second image processing unit 3b recognizes the first recognition target.
