Embodiment Construction

[0015] The present invention will be described in further detail below.

[0016] Infrared thermal imager is a scanning imaging system. Scanning imaging is a process of optomechanical cooperation, and the acquisition of image data is a process of photoelectric conversion. The acquisition time of each column of data is very short compared with the time taken for the infrared column detector array to move horizontally to the next column position. That is to say, there is a long idle time period during the sampling process of the two columns of image data.

[0017] The core of the image data processing method based on the infrared array detector imaging principle proposed by the present invention is to use this idle time period to complete the task of image processing, introduce a pipeline control mechanism, and propose a new method for image data processing—according to The column processing method reduces the total image data processing time and improves the real-time performan...

Abstract

The invention relates to an image data processing method based on an infrared linear detector, which comprises the following steps of: immediately transmitting data to a memory of an image processing system after the data collection completion of each line of images in each frame; carrying out data processing by preset image processing program by the detector to complete partial image processing tasks; and calculating and outputting final results through the image processing program. The invention completes the image data processing by utilizing idle time in two-line image data sampling process on the basis of the image data processing method of the infrared ray line detector, the total image data processing time is reduced, the real-time performance of an infrared imaging system is improved, the processing mode of the infrared ray line detector is changed, the image data operation time is reduced, and the real-time performance of the infrared imaging system is improved.

Description

technical field [0001] The invention relates to an image data processing method based on an infrared array detector, and belongs to the technical field of image data processing of an infrared array detector. Background technique [0002] Infrared thermal imager is a scanning imaging system. Scanning imaging is a process of optomechanical cooperation, and the acquisition of image data is a process of photoelectric conversion. The acquisition time of each column of data is very short compared with the time taken for the infrared column detector array to move horizontally to the next column position. That is to say, there is a long idle time period during the sampling process of the two columns of image data. [0003] The traditional image data processing method is to process the image data after the data collection of the entire image is completed. Such an image data processing flow is shown in the appendix figure 1 . In terms of time sequence, scanning imaging and data pro...
