Abstract

An object of the present invention is to provide is an on-vehicle image processing device that achieves low cost and provides high mounting accuracy and high electrical adjustment accuracy during a manufacturing process. The on-vehicle image processing device includes a first imaging section, a second imaging section, and an enclosure having the first imaging section at one end and the second imaging section at the other end. The on-vehicle image processing device generates a range image from images captured by the first and second imaging sections. The on-vehicle image processing device further includes an enclosure reference surface that comes in contact with an equipment jig during manufacture, the enclosure reference surface being provided at two locations between the first and second imaging sections.

First claim

The invention claimed is:

1. A stereo vision system for vehicle comprising:
a first imaging section, and a second imaging section;
an enclosure having the first imaging section arranged at one end and the second imaging section arranged at another end thereof;
a plurality of first projections that project from the enclosure in a first direction and a plurality of second projections that project from the enclosure in a second direction opposite to the first direction, each of the first and second projections including a vehicle-mounting surface;
a pair of upper reference surfaces disposed on an upper surface of the enclosure, one of which is disposed adjacent to the first imaging section and another of which is disposed adjacent to the second imaging section; and
a pair of enclosure reference surfaces disposed on a same side of the enclosure as the first and second imaging sections and disposed closer to the vehicle-mounting surfaces than the upper reference surfaces;
wherein the upper reference surfaces and the enclosure reference surfaces are references for a jig for electrical adjustment;
each of the plurality of first and second projections includes a cut or ground surface;
wherein the cut or ground surface of each of the first and second projections is exposed in a state in which the stereo vision system is assembled.

2. The stereo vision system according to claim 1 ,
wherein the first projections and the second projections are exposed in the state in which the stereo vision system is assembled.

3. The stereo vision system according to claim 1 ,
wherein the cut or ground surface of each of the first projections is located on a first side thereof; and
wherein the cut or ground surface of each of the second projections is located on a second side thereof.

4. The stereo vision system according to claim 3 ,
wherein the first side of each of the first projections is a surface other than a surface positioned on a projecting direction of the first projections; and
wherein the second side of each of the second projections is a surface other than a surface positioned on projecting direction of the second projections.

5. The stereo vision system according to claim 4 ,
wherein the cut or ground surface of each of the first and second projections is cut.

6. The stereo vision system according to claim 1 ,
wherein the cut or ground surface of each of the first and second projections is cut.
