Funny looking object - (with different viewers)
« on: June 14, 2010, 12:37:10 PM »
On a rainy day I was going through old SI recordings from last summer and found a funny looking object I had earlier dismissed.
The object was about 35 feet from my track and object dimensions are about 5 x 2.5 feet and the height seems to be in the vicinity of 10 inch.
There is a interesting object in the upper left corner too.  It seems to be some kind of large reel or roller with loop of cable or heavy rope hanging downward in the image.

Zoomed up version

The Image looks like this on 798ci

and 6x zoomed version

I made also quick comparison how can I find smaller objects from SI Images of different viewers. Below there is some Images and screenshots from common SI viewers of the same weird looking thing.

I am not yet sure what those objects are, but I am gonna find some day out.

Great picture.   Looks like 2.0 is on the ball.   Chuck

Hello Timo

Why is the red marking on the wrong place   ::)

Hi Gert

The red ellipse shows an estimated target area in HumFinder SI images especially useful if there is number of recordings (and images to be shown) of the same target. The estimation is for taking into account possible GPS error, boat speed, errors in coordinate conversion and calculations.

I guess that the nice structure to the right should have been inside the target ellipse but why it is not? Hmm...

Could it be that the target coordinates are the boat position coordinates and thus estimated target area is shown in the "wrong" place? (Slant correction is taken into account)

Of course there can also be some kind of bug in HumFinder but I haven't noticed this kind of erratic behavior before. In that case could you please sent me the recording (or subrecording) files so I could do some debugging.

By the way, how did you enter the target coordinates to HumFinder? (manually, directly from HumViewer through clipboard, other way...)

Regards,

Timo

ps. Have you tried the object measurement utility yet?

Hello Timo

Yes, your right, the red marks are the boat position, not the target position.

I enter positions manually in Humfinder.  Why -  Humfinder don't accepts  .  (dots)   only  ,   don't know the name.

When do we see next version of Humfinder ?

Great program.

Thanks

Gert

Hi Gert

HumFinder accepts . (dot) as a decimal separator in Lat, Lon values if you use the clipboard to bring the position to HumFinder. Just use for example HumViewer's "Copy position to clipboard" utility and the position will be automatically updated to HumFinder.
You can also copy comma separated Lat, Lon values (regardless of decimal separator) from whatever source to windows clipboard (Ctrl c) and the position will be updated to HumFinder as well.

Supported position formats are:

[+,-]ddd[].dddddd[N,S]      Degrees
[+,-]ddd[] mm.mmmm['][N,S,W,E]   Degrees and Minutes
[+,-]ddd mm['] ss.ssss["][N,S,W,E]   Degrees, Minutes and Seconds

For example copying position "61 19.560N, 24 41.173E" to windows clipboard with (Ctrl c) or using HumViewer's utility tool updates that value automatically in HumFinder.
Entering position coordinates manually you got to use correct decimal separator (. dot or , comma) according to your PC settings.


As to when will be the time for the next HumFinder version - I have some ideas on my to-do list. There hasn't been many ideas in "HumFinder Development Ideas" topic though.  :(  http://forums.sideimagingsoft.com/index.php?topic=767.0
Summertime is quite short here so it's better to leave coding to wintertime and just enjoy the summer and do some scanning..  :)

Timo

Looks like a old outboard motor power head to me with the shaft in the mud. Check pix # 2,3,4,5.  Roddy :)
