Abstract
A system and method for adjusting light emitter output for a railway track inspection system based on data feedback from one or more sensors. The system includes: a power source; a light emitting apparatus emitting light energy toward a railway track; a 3D sensor acquiring three-dimensional data of the railway track; a shaft encoder emitting pulses at a rate that corresponds to a speed of the railway track vehicle; and an algorithm operable on processor to: analyze the three-dimensional data from the 3D sensor; receive pulses from the shaft encoder; and adjust a light emitter control output value based on the analyzed three-dimensional data and the received pulses. A controller in communication with the processor is configured to control the light intensity of the light emitting apparatus in response to the light emitter control output value.
