Crack detection system in the rail tracks. Pierce county relicensing program wa. This is to avoid rail. The project uses a GSM modem duly interfaced to the. Wireless network efficiently for railway track crack detection and the technology can be used at domestic and at commercial places. Instead of manual method of crack.

Here we propose an innovative approach to detect railway track crack as this system detects crack based on image processing. Many image preprocessing steps is used to detect railway track crack. As image is prone to noise.

System converts image to grayscale image and uses filtering to remove noise from image. Noise removal helps to detect crack more accurately.

Image luminous level is increased and image is converted to binary image. This helps system to detect only crack and helps to remove other unwanted objects. Image once converted to binary image, holes are filled by using image processing method this helps to reject all smaller objects which are not required for crack detection. Intensity value is used for accuracy purpose. Blob analysis method is used to detect large blobs. System detects crack based on number of connected components. System detects crack based on number of blobs involved and mentions whether crack exist or not.

Using bounding box functionality, system displays rectangular box around the blob. This system used during railway track inspection. The proposed system is able to detect deeper cracks with 80% success rate and minor cracks with 50-60% accuracy.
