The length of coconut fibre is the main key factor considered for export market. Naturally fibres exits as cross and curve fibres which creates difficulties in taking length measurements. Further, existing methods consume more time. The main objective of this study is to develop an automatic system, which is capable of estimating the length of coconut fibre efficiently and accurately. The system is developed based on image processing techniques. Image taken from a webcam is processed first, and then the processed image is scanned pixel by pixel from the starting point to the end point of fibre. Scanned pixels are stored in an array. The procedure is repeatedly applied for all fibres in the image. Finally the average fibre length is computed through the system and in the testing process, these values were compared with real lengths. The system was tested with single fibres, multiple fibres, and multiple fibres cross one another. Test result indicated that the system functions effectively and reliably.
