Environment setup

Preliminary Requirements:

• Ubuntu 16.04/18.04
• Intel cpu

Compile

source prepare.sh
mkdir build
cd build
cmake ..
make -j

Data preparation

The format of offline dataset follows TUM RGBD Dataset. Example sequences can be downloaded at http://221.228.239.253:81/opensource_data/FlashFusion/dataset.zip Put the dataset at dataset/, organized as

dataset
|---- iclnuim
|---- tum
|---- xtion

Usage

sudo ./FlashFusion sensor_type calib_file voxel_size dataset_path

sensor_type: 0:dataset 1:realtime openni_camera(such as xtion) 2: realtime realsense_camera

Example:
  sudo ./FlashFusion 0 ../param/calib_tum.txt 0.005 ../dataset/tum/fr1_desk/
  sudo ./FlashFusion 0 ../param/calib_icl.txt 0.005 ../dataset/iclnuim/icl0n/
  sudo ./FlashFusion 0 ../param/calib_xtion.txt 0.005 ../dataset/xtion/

  sudo ./FlashFusion 1 ../param/calib_xtion.txt 0.005
