A precision machine vision inspection system and method for increased inspection throughput. The vision inspection system includes a movable stage for scanning and measuring selected workpiece features. In prior systems, conventional interspersing of image processing and inspection operations with image acquisition operations required stopping and starting the stage motion during image acquisition, necessitating associated delays or wait-states in various operations. Such delays are avoided in this invention by acquiring images continuously, with a timing that is independent of image inspection operations, so that delays and wait-states are avoided. In addition, continuous stage motion is combined with a strobe lighting feature during the image acquisition operations to acquire blur-free images at a high rate. Improved image acquisition and image analysis routines including these features are created and stored by the system.
