AUTOOPTIMISER("1")

✨ AUTOOPTIMISER("1") ✨

okay so this is a hugin manual page, bestie — welcome to the group chat 💖

---

🎀 NAME 🎀

autooptimiser — it optimizes image positions. that's the whole vibe. literally its whole job. 💅

---

🌸 SYNOPSIS 🌸

autooptimiser [options] project.pto

and bestie, listen — you can pass - in place of the project file and it'll read the project from stdio instead. iconic behavior, honestly 🫶

---

💜 DESCRIPTION 💜

so autooptimiser works similarly to PToptimizer but — and this is the slay part — it's got extra command-line options. more options, more power, you know how it is ✨

but here's the real difference, and it's kind of a big deal: PToptimizer appends its output onto the input file in the form of 'o' lines, which then need further processing. 💀 extra work? not the move.

autooptimiser keeps it simple: it just updates the project and writes it to a new file. no leftover mess, no extra steps, no cap. 🦋

---

🌈 OPTIONS 🌈

🍓 output stuff

• -o file.pto — the output file. and if you just… don't specify it? stdout is used. lowkey the default L. 🙈

🔥 optimisation options

heads up bestie: if you don't specify any of these, no optimisation takes place. like, at all. it'll just sit there being unoptimised. so pick one, okay? 💀

• -a — auto align mode! it includes various optimisation stages, depending on the amount and distribution of the control points. it reads the room and adapts, main character energy 👑
• -p — pairwise optimisation of yaw, pitch and roll, starting from the first image. systematic. methodical. we love her 🌸
• -m — optimise the photometric parameters ✨
• -n — optimize the parameters specified in the script file (like PToptimizer does). ok retro icon 💅

🦋 post-processing options

• -l — level the horizon. and ngl, it works best for horizontal panoramas — that's just the tea 🍵
• -s — automatically select a suitable output projection and size. it picks for you. self-care, honestly 🫶

⭐ other options

• -q — quiet operation, meaning no progress is reported. for when you simply cannot with the chatter 🙈
• -v HFOV — specify the horizontal field of view of the input images. it's used when the .pto file contains invalid HFOV values — and yes, autopano-SIFT writes .pto files with invalid HFOV. that's a whole thing. that's canon. 😭

💖 the combo move 💖

when -a, -l, -m and -s are used together, you get an operation similar to the one of the "Align" button in hugin. yes. THE button. you're basically pressing it from the terminal. slay 🔥✨
