Embodiment Construction

[0016] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0017] see figure 1 , the high-fidelity infrared complex scene rapid synthesis processing method of the present invention comprises the following steps:

[0018] Step 1, according to the tactical simulation requirements, determine the infrared complex scene images that need to be processed. In the present invention, the way to obtain the infrared complex scene images is as follows: respectively establish theoretical models of typical targets, backgrounds and interference, and predict After processing the infrared spectral radiation characteristic database of typical targets, backgrounds and interferences, each target, background and interference can complete its own image rendering in real time based on the respective infrared spectral rad...

Abstract

The invention discloses a high-fidelity infrared complex scene fast synthesizing method and device. The method includes the steps of A, acquiring radiation images, transparency images and distance images, acquiring the distances from each radiation image and each transparency image to a missile according to the distance images, and arranging all the radiation images and the transparency images in a descending order according to the distances; B, acquiring the radiation value of each of two adjacent pixel points of each distance and the transparency of the nearer pixel point of the two adjacent pixel points, parallelly calculating the synthesizing radiation values of every two adjacent pixel points, and synthesizing the synthesizing radiation values of all the pixel points to obtained a synthesized image. Due to the fact that a graphics processor is used to parallelly process the pixel points and parallel processing can process a large amount of data and is fast in processing, the instantaneity and high fidelity requirements of complex scene image synthesizing can be satisfied.

Description

technical field [0001] The invention relates to the field of weapon equipment automation, in particular to a high-fidelity complex scene synthesis processing method in infrared imaging guidance technology. Background technique [0002] Infrared imaging technology is one of the fast-developing precision guidance technologies in recent years. Its essence is to use the thermal radiation difference between the target and the background to form images of the target and the surrounding scenery to realize automatic guidance. Infrared imaging guidance technology has the advantages of strong target recognition ability, high guidance accuracy, long detection distance, all-weather combat and strong anti-interference ability, so it has become a major development trend of today's precision guided weapons. [0003] With the continuous improvement of the performance of modern infrared imaging devices, the requirements for infrared scene generation technology are also getting higher and hig...
