Hi all,



I've put up my first public release of my new tool: SkySolve



SkySolve is a stand alone application and associated Maxim plugin which performs All Sky plate solves of images.

It requires no initial location hint for the image to solve, but rather uses an all sky reference database to determine where in the sky the image was taken.

It works in tandem with PinPoint, using it to confirm candidate matches and to refine the all sky solution to get sub-pixel accuracy.



SkySolve is now availabe for free download my my website.



winfij.homeip.net/development/SkySolve/index.html



NB. SkySolve requires the full version of PinPoint to operate.



If anyone wants to give it a go, please feel free to send me feedback directly.



One final note - if anyone who wants to give it a go is attending AIC2009 in San Jose this weekend, search me out and I can give you a set of pregenerated reference databases to save you generating your own.



Cheers,



John

Very interesting John. You can bet I'll give it a try...if I ever see

the sky again.

Use it on some of your existing images. Remove the OBJCTRA/OBJCTDEC and any

World Coordinates System (WCS) data which may be there from previous plate

solves, then feed it to All Sky Plate Solve!

How does it stack up against Elbrus in terms of reliability and speed?

How does it stack up against Elbrus in terms of reliability and speed?



Hi Adam,



Elbrus isn't really an All Sky plate solve tool - it's a local solving tool, more like PinPoint.

It does have an "All Sky Search" option, but that simply starts at RA=0 Dec=0 and looks for a solution at each incrementing RA, then moves on to the next Dec band and tries all RA values, repeat until done - it's effectively performing a huge spiral search.



SkySolve builds a reference database of star patterns and matches against that directly, without reference to the RA/Dec of those patterns.



So, it's basically comparing apples and oranges - each has it's place in a balanced diet :)



John



----------------------------

#38610 Oct 31, 2009

In fact, you don't even need to bother removing the keywords - SkySolve ignores them, since if you're running it they are assumed to be incorrect, otherwise you'd just use PinPoint directly.



It doesn't cheat and peek at them - honest ;)



John

Hi Adam,



You piqued my curiosity, so I downloaded a copy of Elbrus and tried solving a random raw image of M51 from my archives:



SkySolve found the solution in 122 seconds.

Elbrus found the solution in 297 seconds.





I then tried a raw image of M20:



SkySolve found the solution in 33 seconds.

Elbrus found the solution in 182 seconds.





Obviously, this is only a sample of two images selected at random - results would likely vary from image to image.





I did also notice that Elbrus requires one to enter the image rotation accurate to within 5 degrees, plus whether the image is mirrored or not. It can operate without entering the rotation setting, but only in a local area which it achieves by trying each rotation angle one after the other in 5 degree steps - it can't do the all sky search in that mode, presumably because it would take too long with the brute force approach.



The pattern matching algorithm implemented in SkySolve operates regardless of image rotation or mirrored state.



Still, Elbrus looks to be a capable program at its target task.



Regards,



John

Hi John.



Thanks for a nice program. Works fine and solves the images i have

tested on my main computer and quite fast to around 30 seconds.



However it didn't work at all on my HTPC computer and after some tests i

found the reason.



On my HTPC i have , as decimal delimiter (, is default in most European

countries. )

For example it gets completely wrong image scale 166,286 instead of

1.66281

Database generation is wring to with , as delimiter. I the database is

created with , delimiter i get a DB that cant be used together with

skysolve even if it's changed to . as delimiter.

Hi John



I am wanting to run the database compilation in stages but it appears to start from the beginning each time I terminate it. Any chance of a mod?



Lawrence Harris







----------------------------

#38623 Nov 2, 2009

Incremental construction of the database isn't trivial, so I have no

immediate plans to implement that I'm afraid.



You'll have it finished by the time I do. ;)

Hi John, Thanks for putting up SkySolve, it seems to work fine except

that , in my case, it solves as J2000 and stores that in the Fits header. I'm using GSC/1.1 which PinPoint also uses and those solves are recorded as JNow.

The WCS that PinPoint produces is in J2000. PinPoint never works in "JNow" (aka

local topocentric).

OK John. I realised that I can let it run continuously on a different laptop -

where it is now nearly finished. Then I'll do a re-compilation with USNO-A2. I

am assuming that the database can be moved to another computer after

compilation?



Thanks for the program.

Hi John,



Once database construction is completed where can I find the database

file/s? On my system (WinXPproSP3) the installation directory is fairly

horrible. I could write down the path but it would be longer than this

missive :) Any chance that can be changed?

It's in your My Documents directory in a directory called SkySolve. It's

not that hard to type is it ? g>

Well you did ask (sort ofg>). The My Documents/SkySolve directory does

not appear to contain the database file I'm looking for. I want to

transfer the database file to a different machine so I don't have to

'recompile' for that machine.

On my system..............



C:\Documents and Settings\wrm\My Documents\SkySolve



contains the following files:



config

exepath

logfile

ShapeIndex16_8 ----- this is the data I believe

skysolve_plugin.dll



your mileage may vary.

"The reference databases, along with other config files and the log file are

stored in the user's Documents folder, in a sub folder entitled .SkySolve.."

Thanks John,



I read that as well. It's just that none of the files I found in that

directory don't look like the the SkySolve database file. I was able to

rename the largest file I could find there and SkySolve still ran. Will

go back and experiment some more in a day or two. Busy with other stuff

right now.



Having fun

Robin
