Typical industrial applications for machine vision
General demands on industrial machine vision Fast Speed Deployment Support Robustness
One key argument for GPUs is their speed
Stronghold of GPUs: Linear operations on pixels Color space transformations Convolutions Distortion correction Image subsampling
Application for GPUs: Color segmentation for AOI
Further methods implemented on GPUs : Stereo Imaging Stereo image pair Disparity image 3D point cloud
Further methods implemented on GPUs: NCC Template Matching Reference image with template Rotation 145º Rotation 288º Rotation 33º
Industrial applications use a wide variety of image sizes VGA 640 x 480 3 MP 12 MP 4x16k Line Scan
GPU acceleration is most efficient for large images Image size 256² 512² 1024² 2048² 4096² 8096² 0 2 4 6 8 10 12 14 Pixel throughput
Applications for GPU: Inspecting large surfaces
