Problem about hypernerf2colmap.py #108

Hellow

Thank you very much for your code, I would like to ask the following questions.

May I ask why the following problem occurs as long as I change 2x to 1x in hypernerf2colmap.py?

guanjunwu commented 8 months ago

hi, because the dataset only has "2x" folder.

cdfan0627 commented 8 months ago

Hi, I am using hypernerf's misc_espresso, which contains dataset has "1x" folder

guanjunwu commented 8 months ago

Hi, if you want to use "1x", I think you can change theimagesize,camera parameters of line 71. Maybe that will work?

cdfan0627 commented 8 months ago

不好意思，但是他的image size是讀camera json檔案的image size，那個camera json檔案的image size，就是1x的image size

guanjunwu commented 8 months ago

我这里是2x的，我觉得你只要把71行的那个 print(idx,"SIMPLE_PINHOLE",image_size[0]/2,image_size[1]/2,cam['focal_length']/2,cam['principal_point'][0]/2,cam['principal_point'][1]/2,file=object_cameras_file) 改成 print(idx,"SIMPLE_PINHOLE",image_size[0],image_size[1],cam['focal_length'],cam['principal_point'][0],cam['principal_point'][1],file=object_cameras_file)，是不是就行了
