Which data to use ?

[trilokpadhi]

Hey @themasterlink
Thanks for the nice repo also sorry for not being detailed .
I downloaded the models by running the code with python download_models.py , and all the models are in the required folder and then when I run the predict data_points.py file with python predict_datapoint.py --output OUTPUT --use_pretrained_weights /home/trilok/SVR-final/SingleViewReconstruction/SingleViewReconstruction/model , I am getting an issue and here is the complete traceback , Can you please help me out ?
Thanks
Trilok

P.S :- Also the color_normal_mean.hdf5 file is there in the data folder

Hey,

could you be a bit more specific?

Hey,

as the exception says, you have the generate the data yourself beforehand. We used SUNCG to generate the training data. However, SUNCG is no longer publicly available, for this reason, we can not share the generated data ourselves. If you already have the dataset SUNCG, you can generate it yourself.

Sorry for the inconvenience. If you don't have access to SUNCG, I would recommend looking into:

https://tianchi.aliyun.com/specials/promotion/alibaba-3d-scene-dataset

They also offer 3D indoor scenes, you might have to adjust the loaders for the SDFGen, but BlenderProc already fully supports 3D Front.

Best,
Max

Hey @themasterlink
Thank you so much your detailed reply , however we just wanted to test the results on a single data sample of yours that is color_normal_mean.hdf5 ? do we need train.tfrecord for it ?
Thanks

Hey,

for just one test image not necessarily, but you need to change the DataSetLoader.py:

SingleViewReconstruction/SingleViewReconstruction/src/DataSetLoader.py

Line 121 in f1475ca

def _deserialize_tfrecord(self, example_proto):

This function returns the current image, normal image and voxel information. You can change that to always use the same test image here to get a certain result. But please make sure to use a camera with the same camera intrinsic as used during the training. As I do not expect that the approach works well with a camera intrinsic shift.

You can generate a normal image with the UNetNormalGen.

The color_normal_mean.hdf5 is used here:

SingleViewReconstruction/SingleViewReconstruction/generate_tf_records.py

Line 123 in f1475ca

normal_o -= normal_mean_img

and here:

SingleViewReconstruction/SingleViewReconstruction/src/DataSetLoader.py

Line 95 in f1475ca

color_img -= self.mean_img

The network was trained with images which were mean-shifted before usage, this has to be done on the test images as well.

Best,
Max
