Advanced line finding handles confusing edges under low contrast and noisy conditions
Traditionally, an edge/line finder has been limited in its ability to locate lines and edge features. A number of simplified edge- and line-finding alternatives work well for good quality scenes with well-defined line features. However, these approaches often fail under low contrast and confusing scenes. Cognex LineMax technology is a breakthrough in finding lines under these conditions.An advanced line-finding tool, LineMax:
- Extracts and locates edge features that make up lines in noisy or low contrast images
- Handles beveled glass and other confusing edges with ease
LineMax uses a random sample consensus (RANSAC) iterative algorithm to sample the image, locate edgelettes within the image, and then find a statistical best fit for the target line. This reduces the impact of outlier points and random noise within the training program. With further specification of the angle or expected length of the line, LineMax’s reliability and speed increase.
