常見問題

找不到牆面怎麼辦？
純白無花紋的牆缺少特徵點，偵測會比較慢。把鏡頭對準畫框邊緣、插座、踢腳線或有紋理的位置，通常幾秒就會找到。這是 AR 的固有限制，不是故障。

框的尺寸看起來不對？
框的大小建立在 AR 對牆面深度的判斷上。距離牆面太近或太遠時誤差會變大，站在約 1 到 2 公尺處最準。可以先用一張已知大小的紙（例如 A4）對照校驗。

多張框會自動對齊，但我想刻意錯開。
吸附只在 2 公分以內作用，超過就完全不會動你的框。刻意錯落的排法（例如高低差 10 公分）會完整保留。

B 系列是哪一套標準？
用的是 ISO 216 B（B2 500×707、B3 353×500、B4 250×353 公釐）。日規 JIS B 比 ISO 大約 2 到 3%。每個尺寸下方都標了實際公釐數，可以直接跟你手上的紙比對。

It can't find the wall. A plain white wall has few features to track. Aim at a frame edge, a power outlet, a skirting board or any textured spot and it usually locks on within seconds. This is an inherent limit of AR, not a fault.

The frame size looks off. Frame size depends on how AR judges the distance to the wall. Standing roughly 1–2 metres away is most accurate. Check it once against a sheet of known size, such as A4.

I want frames deliberately misaligned. Snapping only acts within 2 cm. Anything further is left exactly where you put it.

Which B series? ISO 216 B (B2 500×707, B3 353×500, B4 250×353 mm). JIS B is about 2–3% larger. Each size shows its millimetres so you can compare with the paper in your hand.
