摘要：
For the requirements of the real-time processing of sonar image matching processing, the normal distributions transform (NDT) algorithm and its application in the sonar image processing are studied. The NDT algorithm is based on probability model. The coordinate of target point is calculated instead of the gray value of image, which speeds up the calculation speed of the NDT algorithm. Several methods of image denoising and segmentation are compared to give the results and analysis of each method. Based on TI DSP chip, the NDT image matching algorithm is achieved. © 2016, Editorial Board of Acta Armamentarii. All right reserved.
