Image Processing Technology In The Television Logging

Getting the information of terrane and crevice in mines by taking pictures using camera is an important method, however, lots of image data needs to be processed. Previously the task is done by mankind, it's a hard job and often leads to no efficiency.At the same time, image processing techniques have been used in a larger of fields, it is necessary to design a television logging system and let computer finish all tasks. In this paper, many image processing algorithm have been studied. Firstly, a method to localize compass is proposed, using this method, the degree information can be extracted correctly.Secondly, we use the curve plotting algorithm to unfold the original image, so a cylinder image is available. Thirdly, a new image segmentation algorithm has also been presented to overcome the uneven illumination, it binary each row of image respectively. A method called Max Value Overlap is proposed to process images which contain some parts of the same scene, it is good at reducing imprints in image mosaic. In number recognition, we use the context to validate the correction of initial recognition. In the end, a television logging system has been designed, lots of tests validate that it has the performance of stabilization and speediness.
