Description
These geometric transforms can be quite useful. However when attempting to build for RP2350, the following linker error was produced:
/usr/lib/gcc/arm-none-eabi/13.2.1/../../../arm-none-eabi/bin/ld: firmware.elf section `.bss' will not fit in region `RAM'
/usr/lib/gcc/arm-none-eabi/13.2.1/../../../arm-none-eabi/bin/ld: region `RAM' overflowed by 212320 bytes
It turns out that OpenCV's warp functions make use of large interpolation tables that are made static
:
Rough napkin math shows these tables require >500kB of memory. And because they're static, they all get loaded into RAM. Yikes!
