Embodiment Construction

[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] The invention provides a method for linearly adjusting the laser power of a laser night vision device, as shown in the attached figure 1 As shown, it includes a laser night vision device. The laser night vision device has a built-in main control module, camera lens, D / A converter, and laser power control circuit. The realization process is: the main control module calculates the zoom value of the camera lens and the laser The corresponding relationship between the power parameters, and then adjust the laser power based on the real-time acquisition of the zoom value of the camera lens.

[0022] If the monitored object is in a distant position or when you want to observe the details of the object, you need to zoom out the focal length of the lens. At this time, a larger power is required to achieve a better monitoring effect. Therefore, se...

Abstract

The invention discloses a laser power linear adjustment method for a laser night-vision device. In the method, the laser night-vision device is used, and comprises a built-in main control module, a camera lens, a D / A converter and a laser power control circuit; and an implementation process of the method comprises the steps that the main control module calculates a corresponding relationship between zoom values of the camera lens and a laser power parameter, and the size of laser power is adjusted according to the acquired zoom values of the camera lens in real time. Compared with the prior art, the laser power linear adjustment method for the laser night-vision device adopts a software manner to enable the power of the laser night-vision device to be minimum, so that the power consumption of a product is reduced, and additional cost is eliminated; and in the method, the size of the laser power is adjusted according to the acquired zoom values of the camera lens in real time, so that additional hardware expenditure is eliminated, the practicability is high, and popularization is facilitated.

Description

technical field [0001] The invention relates to the field of optical lighting devices, in particular to a highly practical and linear adjustment method for laser power of a laser night vision device. Background technique [0002] The laser night vision device is composed of infrared laser illuminator, zoom lens, infrared camera, high-definition electric zoom lens, pan and tilt and other equipment. Ultra-low illumination infrared camera design, combined with laser infrared lighting system, realizes all-weather real-time monitoring of color during the day and black and white at night. [0003] Most of the laser night vision devices currently on the market are always working at the maximum power state when the laser is turned on, and do not support the power adjustment function. The furthest monitorable distance of the laser night vision device at night is mainly determined by the maximum power of the laser, but the power of the laser illuminator can be appropriately reduced w...
