Synchronous focusing method for multi-channel imaging equipment and multi-channel imaging equipment

Abstract

The embodiment of the present invention relates to the field of imaging technology, and in particular to a synchronous focusing method for a multi-channel imaging device and a multi-channel imaging device, which are used to solve the problem that the multi-channel imaging device needs to manually zoom after switching channels, resulting in too many manual operations . In the embodiment of the present invention, when the first imaging system of the imaging device detects the target object, the first imaging focal length corresponding to the first imaging system is determined; the processor determines the focal length of the second imaging system according to the first imaging focal length and the focal length transformation matrix The second imaging focal length; the second imaging system adjusts the focal length of the second imaging system according to the second imaging focal length, thereby detecting the target object. The size of the target object detected by the second imaging system is determined by the relationship between the first imaging focal length and the second imaging focal length in the focal length conversion matrix, which avoids the problem that the magnification factor of the second imaging system is too large or too small, so that no further The manual control adjusts the second imaging system, which reduces the manual operation process in the use of multi-channel imaging equipment and enhances the practicality.

Description

technical field [0001] The invention relates to the field of imaging, in particular to a method for synchronously focusing a multi-channel imaging device and the multi-channel imaging device. Background technique [0002] Multi-channel imaging equipment has multiple imaging channels, and these channels have different imaging principles, so the target object can be observed in various aspects. For example, for multi-spectral thermal imaging equipment, it is composed of visible light imaging channel and thermal imaging channel. , the visible light imaging channel can be used to observe the details of the target object under visible light, and the thermal imaging can be used to observe the thermal distribution of visible light under the infrared spectrum. Therefore, multi-channel imaging equipment has a wide range of applications in monitoring, photography, detection, etc. application. [0003] However, the current multi-channel imaging equipment mostly adopts a single-channel...

AI Technical Summary

Problems solved by technology

Since the focal lengths of each imaging channel of the device are independent of each other, after switching the imaging channel, the magnification of the originally adjusted target imaging will be too large or too small. At this time, the user needs to manually adjust the magnification of the imaging channel again. thus increasing the manual process during the imaging process

[0004] To sum up, the existing multi-channel imaging equipment needs to manually zoom and focus when switching imaging channels, which increases the manual operation process and has poor practicability
