Real time rectification using differentially encoded lookup table
Deuk Hyun Park, Hyoung-Seok Ko, Jae Gon Kim, Jun‐Dong Cho · 2011
In this paper, we propose a new real time rectification technique based on the compressed lookup table. To compress the lookup table we adopt a differential encoding. As a result, we successfully constructed the rectification with obtaining the compression ratio of 73% so as to fulfill real-time requirement (i.e., 40 fps at 74.25Mhz). Furthermore, our result on performance is comparable to the result of [17] that obtains 85fps at 90MHz for 640x512 images.
