How it works
Capturing, measuring and calculation: "3 in 1 step" to get the dimensions
Sizensor* utilizes the handheld device camera to detect the cuboid box, gets distance from the laser measure through Bluetooth, and then calculates the dimensions according the handheld device's pitch angle. All processes are integrated by the Sizensor App.
* The App is currently only for Android OS handheld devices.
Distance measured by the laser
When the Capturing process is initiated, the distance between the handheld device and the box’s top surface is also obtained simultaneously by the laser measure. The distance is accurate to millimeters; therefore, it is an essential reference for next step - dimension calculation.
Notice: The box needs to be placed on a level surface.
Cuboid Dimensioning by 3D photogrammetry
"laser-assist 3D photogrammetry" algorithm transforms the photo's pixels into a 3D space coordinates from the distance measured in last step and the pitch angle of the handheld device. The cuboid box dimensions are then calculated from the 3D space coordinates.
