• 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.


  • 1. Capturing

    Automatic box recognition


    Sizensor proprietary image analysis algorithm recognizes cuboid boxes, and defines its three edges (for size measurement) within seconds. It uses the handheld device's 2D camera only. Simply align the blue spot on the front corner, shoot the laser, then the box will be quickly recognized.

  • 2. Measuring

    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. It is the essential reference for next step - dimension calculation.


    Notice: The box needs to be placed on a level surface.

  • 3. Calculation

    Cuboid Dimensioning by 3D photogrammetry

    Sizensor proprietary

    "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.

  • Our 3 Key Technologies

    Smart Recognition


    Automatically recognize the box within a couple of seconds.

    Laser Measure


    The most accurate measurement technology available for handheld applications.

    3D Photogrammetry


    Calculated the box's L x W x H, directly from a single point distance and a 2D photo.
