According to an embodiment, a method and system for color calibration in a three-dimensional multi-color laser scanning system is disclosed. An object may be scanned with the scanning system, which scans the object with color laser heads. Laser intensities, corresponding to laser intensity values, may be received from the scanned object. Three different calibration targets are used to setup a field of view (FOV) calibration profile due to scanning position changes, a surface normal calibration profile due to surface normal direction changes, and a color reflectance calibration profile due to color reflectance changes. After compensating for laser power drift fluctuations, the laser intensity values may be further compensated for field of view scanning position changes and surface normal direction changes using the field of view calibration profile and surface normal calibration profile. Color values of each point scanned from the object may be calculated using compensated laser intensity values from the color reflectance profile.

A method for digital multimedia composition including selecting multimedia data segments, arranging the selected multimedia data segments on a single storyline strip, inserting transitions between adjacent multimedia data segments on the storyline strip, and combining the selected multimedia data segments based on their arrangement on the storyline strip and based on the inserted transitions, to produce a multimedia output file from the storyline strip. A system is also described and claimed.
