PoorMan's Camera

[Psion]

Složka RasACam musí obsahovat všechny stažené soubory.

[Heavy]

Tyto soubory jsem měl v Downloads/RasACam-main, překopíroval jsem je tedy do /home/astroberry/RasACam.
Přejmenoval jsem als na als_jobs, upravil v als cesty, ale stejně to neběhá.. Omlovám se, asi jsem na tohle tupoun

Nemůže to být tím, že to zkouším "bez objektivu"?

[Psion]

Objektiv není potřeba.

Základní předpoklad pro funkčnost je, aby celý software ALS (jeho složka) byl ve složce /home/Astroberry/Downloads.

Snímek obrazovky 2021-03-28 v 12.52.19.png (43.87 KiB) Zobrazeno 1481 x

Druhá podmínka je, že se vytvoří v adresáři RasACam složka als_jobs a ta obsahuje dva adresáře scan a work, se kterými program ALS pracuje.

Nemusí se po tom přesunu soborů z Downloads\RasACam-main do \RasACam opravit "nějaké oprávnění", co se dělalo na začátku?

Ještě je potřeba mrknout do složky als, pokud tam je program (soubor als-0.7-dev-e9dc7de), ten je potřeba přejmenovat na als, ale to už máš, protože to evidentně funguje. Oprávnění by mělo být u spouštěných skriptů nastaveno po instalaci, ale to by hned hlásilo, pokud by chyběly práva ke spuštění (nastavuje se pomoci chmod +x skript.sh). Samozřejmě ALS bez hvězd není možné použít v Stacking modu (funkce Align), tedy je nutné přes stiknutím START odškrnout volbu Align pod tlačítkem.

Zdravím, ještě tam mám nějaké chyby.

I když nemám zaškrtnuto Align, tak se mi po skončení sekvence nic nezobrazí. Ani v ALS a nespustí se vlc.
Kamerka taky vykazuje chyby v obraze, pomocí příkazu raspistill -o ...
Někdy je obrázek OK, někdy vodorovná čára a někdy takhle...
Bohužel se tomu teď mohu věnovat jen pár minut denně.
Kdyby to bylo v každém obrázku, tak bych řekl, že je po ní..., ale takhle nevím.
Děkuji za rady

[Psion]

Těch úvodních chyb si nemusíš všímat, je to nastavením rozlišení, odstranit to rozumně nejde.

Podívejt se do složky /RasACam/als_jobs/scan zda tam je obrázek picture.fits. Pokud je spuštěno ALS tl. START, tak by na konci expozice mělo v okně logs ukazovat průběh načtení souboru FITS. Vyzkoušet se to dá i bez expozice, tedy do složky /RasACam/als_jobs/scan ručně zkopírovat obrázek picture.fits. Chyby v obraze jsem nezaznamenal, v čem je obrázek otevřený?

[zdenek]

Jak na ten obrazek koukam silne mi to pripomina problem, ketry jsem mel pred casem s jinou kamerou. Obcas dala obrazek dobry, obcas byl velmi podobne "postizen" chybou prenosu. Nakonec byl problem v konektoru. Doporucil bych zkontrolovat propojeni/pasek od kamery k Pi.

[Heavy]

Ne v /..RasACam/als_jobs/scan
mám dva soubory
image.fits a image2.fits
picture.fits nikde nevidím.. Nevím kde bych sehnal obrázek ve formatu fits. Šlo by to pomocí příkazu raspistill?
Obrázek je otevřen v prohlížeči obrázků w10, ale stejně jsem to i viděl napřímo na Rpi na monitoru.
--
Pokud kliknu Make picture (JPEG).. zobrazí jen chybu viz výše (asi to rozlišení..)
Make picture (RAW)...

Ano, image.fits je správně. Ten stačí přemístit do jiné složky a pak je znovu vložit do složky scan.

Zkus ještě instalovat toto, zadej v terminálu příkaz: pip install thinker (raspberry musí být připojeno k internetu)

[Heavy]

A mám ho přejmenovat na picture.fits?

[Psion]

ne, tenhle název používá program, spletl jsem název, nejsem u raspberry.

[Heavy]

Doporucil bych zkontrolovat propojeni/pasek od kamery k Pi.

To zkontroluji asi zítra. Dnes už to nedám ..
Děkuji

Mozna to bude opravdu tim paskem, zitra vecer rozeberu a uvidim.
Dekuji za rady
