Go Library for Laser Light Detection and Range-Finding Using a Single Camera
go get github.com/NYU-Efficient-Room-Traversal/Rangefinder
To build the library for iOS, download gomobile
go get golang.org/x/mobile/cmd/gomobile
gomobile init
And build the .framework file in the project directory
gomobile bind -target=ios (xcode is needed)
You may now drag-and-drop the framework into your xcode project
GetLaserOffset(image ImageMatrix) int
Returns the offset of the laser dot from the center plane of the image in pixels. Value will be negative if the laser dot is to the left of the center plane, and positive if the dot is to the right of the center plane.
GetLaserDistance(angle float64, triangleBase float64) float64
Returns the distance from the laser diode to the target based upon the provided angle, at which the pixel offset was corrected by rotating the camera such that the laser dot was in the center plane of the camera.
Calibrate(image ImageMatrix, laserHue float64, initialDistance int, unitSuffix string)
Binds the pixel offset of the laser dot from the center plane of the image to a specified inital distance of units. Example: (image, 0.64, 1, "meters")
