Abstract

The nonuniformity of IR focal plane array

which causes image faint

greatly limited some industrial applications so that the nonuniformity must be corrected prior to the application of infrared imaging technique. A multi-point correction method

which makes use of the powerful computational capability and good programmability of TMS320C6201 DSP hardware

is therefore proposed to do automatically the real-time correction of infrared image nonuniformity. Experimental results showed that the infrared image nonuniformity real-time correction system based on DSP can do the correction in a simple way with satisfactory results.
