Description
As described in title we get the error Error:'camera_ptr_' Must be non NULL when I do sparse reconstruct from known camera poses following https://colmap.github.io/faq.html#reconstruct-sparse-dense-model-from-known-camera-poses.
I get the error when i do 'colmap point_triangulator' with command:
colmap point_triangulator --database_path $DATASET_PATH/database.db
--image_path $DATASET_PATH/images
--input_path $DATASET_PATH/sparse_created
--output_path $DATASET_PATH/sparse
And The errors are:
