Abstract: Provided are embodiments for a device and method for measuring three-dimensional (3D) coordinates. Embodiments include a projector having a projector optical axis on a first plane, the projector operable to project a collection of laser beams on a surface of an object, and a first camera having a first-camera optical axis on the first plane, the first camera operable to capture a first image of the collection of laser beams on the surface of the object. Embodiments also include one or more processors, the one or more processors are operable to generate a first distance profile for the object using a first laser beam of the collection of laser beams and generate a second distance profile for the object using a second laser beam of the collection of laser beams, estimate the velocity of the object based on the first and second distance profile, and provide the estimated velocity.
