Resolution-transforming type eagle eye-mimic visual imaging device and imaging method thereof

Abstract

The invention relates to a resolution-transforming type eagle eye-mimic visual imaging device and an imaging method thereof. The resolution-transforming type eagle eye-mimic visual imaging device comprises a mechanical structure and a control system, wherein the mechanical structure is of a layering type left and right symmetric structure; the whole resolution-transforming type eagle eye-mimic visual imaging device comprises an upper-layer optical structure and a lower-layer PTZ (pan / tilt / zoom) control structure to realize servo control and resolution transformation functions; the mechanical structure comprises two fixed-focus industrial cameras, two board level industrial cameras, a lens switching device and a two-degree-of-freedom PTZ; the control system comprises an image processing unit, a rudder control unit and a power source unit. The resolution-transforming type eagle eye-mimic visual imaging device has the advantages that a visual system can be guaranteed to monitor a large-area scene, inspect and position a doubted goal, and analyze and measure with high resolution; the defect of mutual contradiction between the precision and the vision field of a single camera is overcome; the goal detection efficiency is obviously improved, and the application range is wider.

Description

【Technical field】 [0001] The invention relates to a resolution-transformable imitation eagle-eye vision imaging device and an imaging method thereof, belonging to the fields of vision imaging technology and bionic technology. 【Background technique】 [0002] Vision is an important information acquisition system. Due to the low cost and ease of use of visual sensors, visual imaging systems have been widely used in various aspects of life, including monitoring, industrial product inspection, optical measurement, drones, satellites, etc. However, most of the vision systems currently on the market are designed for simple image data collection, with a relatively single structure and function. The combination of a simple industrial camera and a fixed-focus lens often leads to a limited field of view of the vision system, low utilization of image information, and it is difficult to meet the requirements of large field of view and high precision at the same time. Although zoom data...

However, most of the vision systems currently on the market are designed for simple image data collection, with a relatively single structure and function.

The combination of a simple industrial camera and a fixed-focus lens often results in a limited field of view of the vision system, low utilization of image information, and it is difficult to meet the requirements of large field of view and high precision at the same time

Although zoom data acquisition can be achieved with a zoom lens, the structure of the automatic zoom system is relatively complex and difficult to program control. Therefore, it is necessary to design an intelligent vision system that can meet various needs and is easy for users to operate.
