'[EE]: Alignment Sensor'

Resend....My tag was not exactly correct....

Have you ever tried to align a goose neck trailer, to a ball in
the bed of a truck, with your wife giving you finger directions?
Not pretty.......
Note: Extended cab with a tool box.  The ball is completely out of site.

I would like to build a sensor using a PIC and possibly LED's for
a display to help me hook up a horse trailer.  Any Ideas?

I thought about that..I could mount the camera on a magnetic base and use it
during alignment. The problem is the angle would be hard to see without two
cameras, and two monitors.

How about a mirror clamped on to your tailgate, angled so that you can see
the hitch?

I was thinking you would shoot down from above, (keeps crud off the camera
too) and include enough of the bumper in the shot to show the angle between
the truck and the hitch.
You could do two cameras, one wide for getting lined up, and one narrow,
for "docking".

The pic would come in, with some image processing, to automatically dock to
the trailer :)

And how would you use a PIC (or anything cool or 'tronic) in that
arrangement?

Dear Gordon Varney,

"Gordon Varney (personal)" <varneyspamKILLspamCLAS.NET> on 2001-05-03 cast his net for
ideas:

Brainstorming ...

How about one of those "line draw" lasers (I've seen the heavy ones with a
rotating mirror, but I've heard there's some sort of solid-state lens that does
the same thing) mounted on a hight point on the trialer. It makes a (unmoving)
bright line on the top of the hitch, along the ground directly in front of the
trailer, and (when properly aligned), across the length of the truck bed,
through the back window of the truck, up the dashboard, and down the hood.

When the truck is directly in front of the trailer and perfectly lined up (The
line helps you line up left/right and yaw), the line hits the exact center of
the dashboard and exactly the length of the crease in the middle of the hood.

Then you just have to have your wife wave you backwards and forwards until your
ball is directly under the hitch.

sorry, just had to laugh, remembering all the times my wife gave me "finger
directions" when getting ready to go camping...

Maybe an inductive pickup arrangement?  A couple of metal detectors set at
angles and a bar graph on the dash board?  Although the camera option might
be a simpler brute force method.

Actually, using two laser pointers at right angles, mounted in the truck
bed, and directed so as to point onto the goose neck arm when aligned.  A
camera mounted at a 45 deg angle to both might allow alignment of both front
to rear and side to side. Hmmm....

Huh...  Yeah, mine gives me finger directions, but it's always the same
direction.

Why ?  You are manouvering in two dimensions, right ?  The camera needs to
look down from slightly above the hitch. It will cover a fov of 45 degrees
at least so you'll be able to see the hitch and several feet out in all
directions.

For hooking up to my boat trailer I look along *UNDERHEATH* my 4 wheel drive
with the aid of 2 mirrors.
A plane (flat) mirror permanently mounted on the top (back) of the bull bar
shows me the ground under my front bumper (from the centre of the vehicle to
the passenger side - great for getting in/out of close parking spaces too).
A convex, curved (in the horizontal plane only) mirror on a short bar is
hooked over the bull bar to hang down under the front bumper when I need to
mate the trailer couplings (which are painted reflective white underneath).
This mirror is always clipped to the top of my tool box when not in use -
it's great for looking behind wheels, on top of gear boxes, etc.

This works great with my 4 wheel drive (which is less than 4m long), though
it may not be so good for an extended cab truck.  But maybe you could find
an alternative path to set up a periscope for your particular truck?

Not a PIC solution, but sometimes you just don't need high tech to solve a
simple problem.

Bye.
