# Sequence SfM

This program is a demo to show structure from motion for sequence images input. The program is based on https://github.com/royshil/SfM-Toy-Library, but we fix some bugs and use Qt as the interface. You can add more advanced tricks such used in PTAM or ORB-SLAM, to make it faster and robust. 

## 1. Plateform
Use Ubuntu 18.04 or later.


## 2. Requirements

* SuiteSparse 
* Qt4
* g++ 4.8

```
sudo apt-get install libsuitesparse-dev
sudo apt-get install libqt4-core libqt4-dev
sudo apt-get install gcc-4.8 g++-4.8
```

## 3. Build:

由于本项目使用老版本的Feature，因此必须使用OpenCV 2.4。需要确保系统里没有安装其他版本的OpenCV。具体安装的方法请参考[《OpenCV安装说明》](https://gitee.com/pi-lab/pi-slam/blob/master/thirdparty/opencv_install.md)


### 3.1 Build command

```
mkdir build; cd build
cmake -DCMAKE_CXX_COMPILER=/usr/bin/g++-4.8 \
    -DCMAKE_C_COMPILER=/usr/bin/gcc-4.8 \
    -DOpenCV_DIR=/opt/opencv-2.4.9/share/OpenCV \ ..
make
```


## 4. Usage
```
./SequenceSFM fn_in=../data/img_sfm_1s
```
