摘要：
Flexible 3D curved LED video walls require enhanced image processing. An all-in-one warping software was developed which measures and corrects geometrical distortions. LEDs as point sources in combination with a non-regular pixel distribution need special algorithms for angular emission characteristic and local density, adjustment of grey shades.
