Abstract

The invention provides a moving image rapid synthesis method and device, equipment and a medium, and the method comprises the steps: setting an imaging period according to the speed and height of an inertial sensor through employing a known linear array pixel resolution; the method comprises the following steps: acquiring a non-uniformity corrected image output by a signal processing circuit of an infrared array detector, and adjusting the position of even row / odd row image data under the condition of fixing the odd row / even row according to speed information provided by an inertial sensor and through inherent distance parameters of the odd row and even row of the infrared array image and an imaging period of a linear array camera, so as to obtain the position of the even row / odd row image data. Performing parity correction; acquiring an image after odd-even correction, marking longitude and latitude information at the middle position of a storage space of a storage circuit according to the longitude and latitude information corresponding to a central pixel of the linear array image provided by an inertial sensor, and placing the linear array image after non-uniformity correction and odd-even correction by taking a longitude and latitude coordinate point as a center and a flight track of an airplane; and the linear array data is output to the storage circuit in a strip graph.

Description

technical field [0001] The invention belongs to the field of infrared image processing, in particular to a method and device for quickly synthesizing moving images based on an inertial sensor. Background technique [0002] With the rapid development of machine vision, vision sensors are favored by vision engineers and users. The infrared sensor is affected by the process, which causes the contradiction between the large pixel size and the large-scale area array. In order to obtain high-precision energy resolution, infrared line array sensors are widely used in aerospace / aviation and other fields. In line array pushbroom imaging, according to the characteristics of the line array sensor, the pushbroom image presents a strip image. [0003] The existing infrared line array sensor imaging has the following problems: 1) Image overlap and missing shots: the accurate imaging cycle cannot be optimized and adjusted reasonably, there is a certain overlapping area in adjacent frame ...
