#43 測試發現伸展的手臂、筆、雨傘桿都會破洞甚至擷取不出來,看可以怎樣改善。

根據 alicevision 的討論
alicevision/Meshroom#565
alicevision/Meshroom#505
alicevision/Meshroom#536

可以瞭解解法通常是放大物件、增加特寫,讓被攝物佔畫面比例多一點,但這不符合 4D 的狀況。

要再想辦法解決這件事情。

像這種揮手手指完全吃掉的,要想辦法調整參數解決才行。

昨天林老闆拍了兩組測試。

今天已經解完 depth 2 的,再試著解一組 depth 1 的試試看。

下面是目前 depth downscale 差別的解算時間。

解算步驟 depth 2 depth 1
depth 6:02 27:07
mesh 4:48 13:04

depth 1 depth 2
scale_1 scale_2

效果沒有比較好,運算時間四倍長,而且還讓邊緣更毛躁抖動,也查了一些討論說 維持原解析度解scale很沒必要,放棄增加 depth 解析度。
