Embodiment Construction
[0036] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution, and provides detailed implementation and specific operation process, but the protection scope of the present invention is not limited to the present invention. Example.
[0037] Such as figure 1 As shown, a camera system based on off-axis optical path technology includes an imaging objective lens 1, a camera 2, and an attitude control structure 3, and the imaging objective lens 1, camera 2, and attitude control structure 3 are arranged sequentially in the direction of light propagation ; Wherein, there is always a certain off-axis offset d between the central position of the target surface of the camera 2 and the main optical axis of the imaging objective lens 1, so as to obtain the image of the imaging objective lens 1 edge field of view; the attitude control structure 3 is connected to the The...

The invention discloses a camera system and method based on off-axis optical path technology. By setting the offset between the central axis of the camera target surface and the main optical axis of the imaging objective lens, an off-axis angle of view is formed. Combined with a small format camera and The design of the large-format fixed-focus lens, when the camera target surface stays at a certain position, the lens and the camera target surface form a system combination, when the camera target surface is controlled to rotate around the main optical axis of the objective lens, the camera is within the field of view of the lens A larger imaging range is obtained, thereby obtaining a second group of system combinations. In this way, an imaging system with two different parameters of field of view and target ratio is formed, which is compact in structure, small in size, and has the same image clarity under the two parameters. At the same time, when the camera system shoots the target, due to the off-axis viewing angle, it does not need the equipment lens to face the target directly. After the installation is completed, it can reduce the dead angle of the direct view and improve the observation range.
Description
technical field [0001] The invention relates to the field of optical imaging, in particular to a camera system based on off-axis optical path technology. Background technique [0002] In the field of optical imaging, an imaging system with a set of imaging objective lens and camera parameters determined, the imaging range that can be imaged is the field of view and the proportion of the target at a specific distance in the frame is fixed. However, in actual use, there are different requirements for the range of the scene or the distance of the target, the proportion of the screen and other effects. For each different requirement, different combination modes of different objective lenses and cameras are required. This is why the operator needs to constantly change the objective lens and even the camera during the actual shooting. The operation of replacing the system is relatively complicated. In many cases, after the system assembly is completed, the best time to shoot the ...
