Problems solved by technology
In order to capture large-format images, the existing imaging equipment has the following two deficiencies in one imaging method: 1. The existing imaging equipment can achieve images larger than the imaging format through multiple shootings, but the efficiency of multiple imaging is low
2. Renovate the lens and sensor format of existing imaging equipment, increase the lens pupil radius of the imaging device, manufacture and configure larger format sensor devices (film or digital sensors), and match and adapt to larger format image post-processing Processing equipment (such as fixing, developing equipment, etc.), but the realization of this approach is expensive, long-term, and difficult
In short, it is difficult to realize larger format imaging photography process with existing imaging equipment

Embodiment Construction
[0015] As shown in FIG. 1 and FIG. 2 , the device of the present invention includes a primary image-carrying lens 1 , a primary image-carrying device 2 , a secondary imaging lens 3 and a secondary imaging device 4 arranged in sequence. The image-bearing surface of the primary image-bearing device 1 is placed at the imaging surface of the primary image-bearing lens, and after the scene to be photographed is captured by the primary image-bearing lens 1 , the image of the scene is presented on the primary image-bearing device 2 . At the back end of the primary imaging device 2 , a secondary imaging lens 3 is placed, which can perform secondary acquisition of the image presented by the primary imaging device 2 and present the scene image on the imaging surface of the secondary imaging device 4 .
[0016] As shown in Figure 3, the primary image bearing device 2 is the key component of the imaging system. The primary image bearing device 2 is composed of two layers, the image bearing...

The invention relates to a secondary image camera method and a relative device, wherein the method comprises that (1), providing a device with a first intercepting lens, a first intercepting device, a second image lens, and a second image device, (2), according to the object-image symmetry relation of the first intercepting lens, arranging the first device on the image face of the first intercepting lens, to make the plane of the first intercepting device vertical with the main optical axis, to display the collected image on the intercepting face of the first intercepting device, and the image light penetrates the first intercepting device, (3), arranging the second image lens and the second image device at the back of the first intercepting device in turn, making the intercepting face of the first intercepting device and the image face of the second image device into symmetry relation via the second image lens, to display the image of the first intercepting device on the second image face. The invention can realize the image process with large area and camera area, to support remote-sensing mapping and medical image processing technical field.
Description
technical field [0001] The present invention designs a photographing method and device, in particular to a photographing method and device that utilizes the geometrical principle of optical imaging to carry out a second image after receiving an image. Background technique [0002] Almost all photogrammetry methods widely used at present are photography methods based on the principle of primary imaging geometry. Widely used cameras include a film camera using a film as a sensor and a digital camera using a CMOS or CCD sensor. Regardless of film camera or digital camera, the imaging format is generally below 5cm×5cm, and only aerial photographic film can reach 21cm×21cm. In order to capture large-format images, the existing imaging equipment has the following two disadvantages in one imaging method: 1. The existing imaging equipment can achieve images larger than the imaging format through multiple shootings, but the efficiency of multiple imaging is low. 2. Renovate the len...
