Development of mining intrinsic safety drill imager application based on Android system

Abstract： In order to further enhance the ability of detailed drilling detection, a mine intrinsically safe borehole imager application based on the Android system is developed. Through a deeply data mining and fusion of video, depth and angle information which has been acquired, it functions such as video acquisition, image unwrapping, probe attitude, 2d/3d trajectory etc. A set of "mapping transformation" algorithm was designed to optimize the image expansion function and improve the image expansion speed by 137%, real time drilling image development is achieved.The communication interface technology based on JNI and edge computing was introduced, and the data preprocessing of the electronic compass and depth counter was completed in the hardware interface, which reduced the load of the host by 4.6%. The experiment shows that the software of borehole imager allowed full play to the hardware performance of borehole imager and improved the construction efficiency of borehole observation.
