WebSep 9, 2024 · An ad hoc developed image processing algorithm analyzes the spectral and geometric information of the melt pool from high-speed camera images and distinguishes between complete and incomplete cuts ... WebPrinciple of operation of a time-of-flight camera: In the pulsed method (1), the distance, d = c t / 2 q2 / q1 + q2, where c is the speed of light, t is the length of the pulse, q1 is the accumulated charge in the pixel when light is emitted and q2 is the accumulated charge when it is not. In the continuous-wave method (2), d = c t / 2 π arctan q3 - q4 / q1 - q2.
