The invention discloses a signal processing module, comprising: preprocessing the airborne image signal to generate a preprocessed image signal and sending it to a parallel port network; performing mirror image processing on the preprocessed image signal to generate a mirrored image signal and sending it to the parallel port network; Preprocessing the image signal for target recognition to generate a main recognition image signal, and performing target recognition on the mirror image signal to generate a secondary recognition image signal, which is sent to the parallel port network; encoding the main recognition image signal to generate a first image signal and sending it to the motherboard. The invention also discloses a signal processing method. The signal processing module and method of the present invention ensure the immediacy and accuracy of target recognition in infrared images under the premise of domestic low-frequency processors and domestic low-field infrared equipment, and make a significant contribution to the safety of electronic equipment , and is conducive to the miniaturization of the module, reducing the space occupied by the airborne equipment.
Description
technical field [0001] The invention relates to image signal processing technology, in particular to a signal processing module and method. Background technique [0002] With the rapid development of infrared technology, infrared imaging recognition technology has begun to be applied on a large scale, and both civilian technology and military technology have begun to use infrared imaging recognition as an important means of target recognition. [0003] In the civil field, in a large area of forest, fires are often caused by inconspicuous hidden fires. This is the source of destructive fires, and it is difficult to find the hidden signs of fires with existing common methods. However, patrolling by aircraft and using infrared thermal imaging cameras can quickly and effectively discover these hidden fires and eliminate the fire at the beginning. The Canadian Forestry Institute began forest fire prevention experiments as early as 1975, checking potential fire sources that ha...
