Abstract
Abstract An obstacle detecting device for a vehicle comprises a pair of image sensors for taking an image of an object surrounding a vehicle, a display image plane for displaying an image data taken by said pair of image sensors as an image, and a plurality of windows designating regions of said image on said display image plane. The device further comprises an optical obstacle detecting device for detecting distances from said vehicle to said object in said regions of the image designated by said plurality of windows for the respective windows to thereby detect an obstacle, a laser radar device mounted on the vehicle for radiating a radar beam to the object surrounding the vehicle to thereby detect said obstacle, and an obstacle selecting device for selecting either the obstacle detected by said optical obstacle detecting device or the obstacle detected by said laser radar device mounted on the vehicle.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
156 words
An obstacle detecting device for a vehicle comprising: first and second image sensors for sensing an environment, including an object, external to said vehicle and outputting first and second image data, respectively, representative thereof; a display image plane for displaying said first image data as a display image including an image of said object; means for designating a plurality of regions of said display image on said display image plane; optical detecting means for detecting distances from said vehicle to said object when said image of said object is in at least one of said regions of said display image; a device mounted on said vehicle for radiating a beam to said object and receiving a reflected beam therefrom to detect distances from said vehicle to said object; and microprocessor means for causing, based on a predetermined condition, either said optical detecting means or said device to detect the distances from said vehicle to said object.
Claim 2
Dependent Claim
156 words
An obstacle detecting device for a vehicle comprising: first and second image sensors for sensing an environment, including an object, external to said vehicle and outputting first and second image data, respectively, representative thereof; a display image plane for displaying said first image data as a display image including an image of said object; means for designating a plurality of regions of said display image on said display image plane; optical detecting means for detecting distances from said vehicle to said object when said image of said object is in at least one of said regions of said display image; a device mounted on said vehicle for radiating a beam to said object and receiving a reflected beam therefrom to detect distances from said vehicle to said object; and microprocessor means for causing, based on a predetermined condition, either said optical detecting means or said device to detect the distances from said vehicle to said object.
Claim 3
Dependent Claim
64 words
An obstacle detecting device as claimed in claim 1, further comprising: means for determining a position of a steering wheel of said vehicle and outputting steering signals representative thereof; and means for determining, in accordance with the steering signals and the detected distances of said vehicle to said object, a position of said object with respect to a direction of movement of said vehicle.
Claim 4
Dependent Claim
34 words
An obstacle detecting device as claimed in claim 2, further comprising means for signalling, based on the determined position of said object, when said object is less than a predetermined distance from said vehicle.
Claim 5
Dependent Claim
64 words
An obstacle detecting device as claimed in claim 1, wherein: said display image includes an image of a second object present in said environment; and said optical detecting means further detects distances from said vehicle to said second object, while detecting distances from said vehicle to said first object, when said image of said second object is in at least one of said regions.
Claim 6
Dependent Claim
34 words
An obstacle detecting device as claimed in claim 1, wherein said optical detecting means detects the distances from said vehicle to said object when said image of said object is in multiple said regions.
Claim 7
Dependent Claim
15 words
An obstacle detecting device as claimed in claim 1, wherein said regions are substantially rectangular.
Claim 8
Dependent Claim
29 words
An obstacle detecting device as claimed in claim 1, wherein said region designating means positions said regions substantially linearly with respect to each other across said display image plane.
Claim 9
Dependent Claim
29 words
An obstacle detecting device as claimed in claim 1, wherein said region designating means positions said regions substantially non-linearly with respect to each other across said display image plane.
