# SFM
Structs for interacting with reconstruction data from different SFM programs
* COLMAP
* Cameras
* Points
* OpenSFM
* reconstruction.json
* Meshroom
* cameras.sfm
## COLMAP
### Point Data
Interact with COLMAPS's `points3D.bin` file output under the sparse reconstruction data.
```golang
package example
import (
"fmt"
"github.com/EliCDavis/sfm/colmap"
)
func main() {
points, err := colmap.LoadPoints3DBinary("ColmapProject/sparse/0/points3D.bin")
if err != nil {
panic(err)
}
fmt.Printf("File contains %d points", len(points))
}
```
### Cameras
Interact with COLMAPS's `cameras.bin` file output under the sparse reconstruction data.
```golang
package example
import (
"fmt"
"github.com/EliCDavis/sfm/colmap"
)
func main() {
cameras, err := colmap.LoadCamerasBinary("ColmapProject/sparse/0/cameras.bin")
if err != nil {
panic(err)
}
fmt.Printf("File contains %d cameras", len(cameras))
}
```
## Meshroom
Interact with Meshroom's `cameras.sfm` file output from the `StructureFromMotion` step.
```golang
package example
import (
"fmt"
"github.com/EliCDavis/sfm/meshroom"
)
func main() {
cameras, err := meshroom.LoadCameras("MeshroomProject/MeshroomCache/StructureFromMotion/abc123/cameras.sfm")
if err != nil {
panic(err)
}
fmt.Printf("File contains %d Poses", len(cameras.Poses))
}
```
## OpenSFM
Interact with OpenSFM's `reconstruction.json` file output from the `reconstruct` step.
```golang
package example
import (
"fmt"
"github.com/EliCDavis/sfm/opensfm"
)
func main() {
reconstructions, err := opensfm.LoadReconstruction("MyOpenSFMProject/reconstruction.json")
if err != nil {
panic(err)
}
fmt.Printf("File contains %d reconstructions", len(reconstructions))
}
```
