Imaging System Relay Component Comparison

Below is a table for Comparison of the two relay image transmission components

wdt_ID Attributes Relay camera solution Optical Fiber imaging solution
1 Volume and weight Bulky and heavy Compact size and light weight
2 Structural complexity The relay camera structure is more complicated The system structure is relatively simple
3 Stability and Reliability Poor system stability and reliability Good system stability and reliability
4 Split field of view image stitching Seamless stitching of the field of view by overlapping the fringe field of view of the miniature camera Unable to achieve seamless splicing of the field of view, there are less than 10 pixel gaps
5 Development difficulty There are a large number of miniature cameras, and each camera needs to be precisely aligned with the concentric objective lens, so the processing accuracy of the physical casing is extremely high, and the assembly and adjustment are extremely difficult. The number of fiber optic panels is small, and the installation and adjustment are relatively simple
6 Image Processing Image overlap of miniature cameras leads to complex image registration and fusion algorithm There is no overlapping area, and the assembly and registration fusion algorithm is relatively simple

Below is a table for Comparison of the two relay image transmission componentsThe two schemes have their own advantages and disadvantages. The relay camera scheme can achieve seamless splicing and has high image quality. Since many miniature cameras can be individually controlled, this scheme can perform local image quality fine-tuning, aberration correction, etc. , the biggest disadvantage of this scheme is that the camera is bulky and heavy, and in order to achieve seamless splicing, the imaging between the micro-cameras will produce image overlap. Therefore, the image registration and fusion algorithm of this scheme is relatively complex. The optical fiber image transmission scheme is superior in small size, light weight, relatively simple system structure, and good system stability and reliability. However, the biggest disadvantage of this scheme is that it cannot achieve seamless splicing, which makes some information always missing during the imaging process, but also brings the advantage of a relatively simple image registration and fusion algorithm.
