Abstract

The invention discloses a rapid extension method for optical scene images. The method comprises the following steps of: S1, obtaining a measured image and determining an extension image size and an extension operator of the image; S2, calculating a numerical value of a single pixel point in the image and carrying out extension layer by layer from inside out; S3, respectively a clockwise extended image and an anticlockwise extended image; and S4, averaging the clockwise extended image and the anticlockwise extended image so as to obtain a final extended image. According to the method, the application problem that the measured data is not matched with optical imaging scene generator field angles in simulation experiments is solved, and rapid extension can be carried out on the measured data according to the optical imaging scene generator field angles under the premise of not influencing the work of detection systems, so that the smoothness of the optical simulation experiments is ensured and the method has a wide application prospect.

Description

technical field [0001] The invention relates to an image processing method, in particular to a rapid expansion method for optical scene images. Background technique [0002] The optical scene simulation system needs to load the measured data to test the performance of the optical detection system. Because the field of view angles of the measured data acquisition equipment and the optical imaging scene generator may be different, sometimes the measured data cannot completely match the optical imaging scene generator. When the field of view of the measured data is too large, it can be cropped directly; but when the field of view of the measured data is too small to completely cover the optical imaging scene generator, it is necessary to expand the measured image data without affecting the existing data. The simple monochromatic background filling method may cause misoperation of the optical detection system, so it is necessary to combine the measured data information for epit...
