Thermal imager hybrid zoom control and identification display system, thermal imager and readable storage medium

Abstract

The invention provides a hybrid zoom control and identification display system of a thermal imager, which collects the feedback value of the current optical zoom lens position; if the current zoom far command is executed, and the current optical zoom lens position feedback value is the maximum value, the optical zoom motor stops Run, switch the current zoom state to digital zoom, mark it as a digital zoom sign, and the digital zoom indicator changes until the maximum value of the electronic zoom; if the current zoom near command is executed, and the current digital zoom ratio ScalerNx is equal to 1.0, switch to optical zoom near The motor works; the digital zoom factor is obtained during digital zoom, and the zoom input resolution is obtained, and related module settings are performed according to the zoom input resolution; the present invention avoids the small zoom factor of the optical continuous zoom lens, which cannot be continuously electronically enlarged; it also solves the problem of When zoomed to the optical maximum, the target is still small. It avoids the need to manually switch to digital zoom, poor continuity of the zooming process during manual operation, and large zooming errors during operation.

Description

technical field [0001] The invention relates to the technical field of infrared thermal imager zoom, in particular to a thermal imager hybrid zoom control and identification display system, a thermal imager and a readable storage medium. Background technique [0002] At present, when a thermal imager with continuous zoom is in use, it is necessary to perform the zoom operation of the thermal imager lens. During the zooming process, it is usually impossible to intuitively judge the current zoom position, and it is impossible to know whether the optical zoom limit is reached, which affects the thermal imager. usage of. [0003] In the prior art, thermal imagers also have the following problems: [0004] The zoom factor of optical continuous zoom lens is small and cannot be continuously electronically enlarged; [0005] When zooming to the optical maximum focal length, if the target is still small, it is necessary to manually switch to digital zooming. During the manual opera...

AI Technical Summary

Problems solved by technology

[0004] The optical continuous zoom lens has a small zoom factor and cannot be continuously electronically enlarged;

[0005] When zooming to the optical longest focus, if the target is still small, it needs to be manually switched to digital zoom. During the manual operation, the continuity of the zoom process is poor, and the zoom error is large during the operation

If there is a hard limit switch, it is easy to cause limit position error
