Embodiment Construction

[0037] Specific technical solutions such as image 3 As shown, the sinusoidal signal generated by the sinusoidal signal generator is used to modulate the laser generated by the semiconductor laser, so that the semiconductor laser generates a sinusoidal signal to modulate the laser, and the sinusoidal signal modulated laser is diverged by the optical divergence lens and then irradiates the target field of view; the target scattering of the target field of view After the laser and background light are filtered by optical filters, they are collected by the CCD focal plane array at a constant speed to obtain a series of sensing images of the target field of view; the sinusoidal signal generated by the sinusoidal signal generator and the target field of view collected by the CCD focal plane array are The sensing image of the field is stored in the memory in the video processing circuit, and the phase detection processing of the sensing image of the target field of view is completed ...

Abstract

The invention discloses a laser lock imaging method and a device, which belongs to the technical field of electronic information and relates to an image processing technique. Periodically modulated laser is adopted to irradiate a target area, partial background light in a target viewing field is filtered by optical filtering and is then processed by phase demodulation which is detected by weak signals, and a target image in the target viewing field is extracted from the strong background light. By using the method and the device, the clear target image can be extracted from the strong background light, and the background light suppression ability is great. The method and the device can be applied to aiming systems in traffic monitoring, industrial monitoring and weapon equipment and night-vision equipment.

Description

technical field [0001] The invention belongs to the field of electronic information technology, relates to image processing technology, and specifically refers to a laser locking imaging method and device with the function of eliminating background light. technical background [0002] Usually, when the strong background light and the imaging target are in the field of view of the imaging system, the target image will be lost in the strong background light or complex background and cannot be distinguished, which will cause the imaging system to lose the ability to image the target. The existing CCD image sensor will lose its imaging ability due to saturation under strong background light. [0003] In industrial monitoring, the monitoring environment is often unavoidably disturbed by strong light sources. For example, the detection of molten steel and other metal liquid levels, due to the high temperature and strong flames, currently lacks effective imaging detection methods....
