It is reduced to the lower image half with ÐÔ ÖÓÒ. The operator ÖÙ ÓÑÒ creates an image containing this pattern as definition range. This image is passed to the operator ×ÓÐ ÑÔ. You obtain pixels with high gradient values using ØÖ×ÓÐ. These pixels are enlarged to the region of interest (ROI) by a dilation with a rectangular mask. Within this region another thresholding is performed. Correct road markings are equivalent to bright areas in the search window (ROI). The HALCON program needs an average of 20 ms on a standard Pentium. Notice that this is even possible under the following restrictions: 1. Only standard operators have been used. 2. Only encapsulated data structures have been used. 3. Despite optimization the program is quite comprehensible. 4. The program is very short. This example shows that you can write efficient programs even while using complex data struc- <strong>HDevelop</strong> / 2000-11-16
