Description

multi-mode aiming device

technical field

The present application relates to the field of image processing, in particular to a multi-mode aiming device.

Background technique

At present, the mainstream sighting devices on the market are mostly white light or low-light sighting scopes with a single optical path. Their observation conditions are relatively limited, and they cannot work in some extremely harsh environments, such as thick smoke and fog. Infrared sighting scopes can just make up for this For this shortcoming, the infrared sight can be used both during the day and at night, but the infrared sight cannot see the details of the prey, and cannot accurately distinguish what animal it is.

For professional hunters, a hunting lasts a long time, and hunting scenes not only have hunting needs during the day, but also at night. Therefore, hunters want to use white light sights in the daytime, the details are clearer, and use infrared sights at night to search and target prey. Usually, there are only two options: one is to carry 2 scopes and 1 shotgun, however, carry 2 sights Mirror 1 shotgun will face the problem of repeated gun calibration. In this way, when switching between the two scopes, one of the scopes needs to be removed and the other scope needs to be installed. Every time it is disassembled, it must be recalibrated Gun, this kind of frequent disassembly and assembly is very inconvenient. There is no special place for gun calibration when working in the field. Install a white light sight on one gun, install an infrared sight on the other gun, calibrate the gun before departure, and use it directly when hunting. However, one person needs to carry two shotguns at the same time, which greatly increases the carrying burden of the user. Increase the cost of buying guns.

As a scope user, he is more concerned about how to capture and aim at targets faster and more accurately in different environments, and this gives space for the application of multispectral imaging technology in thermal imaging sighting devices.
