Research on Machine-vision Aiming Technology for New Generation Launch Vehicle

提出一种用于新一代运载火箭的机器视觉瞄准技术,在瞄准仪上集成摄像系统,用于采集被瞄目标图像,利用机器视觉图像识别算法,包括灰度变换、形态学分析、OCR算法等,进行图像识别,实时测量火箭上的被瞄目标相对于瞄准光轴的位臵信息。该方法具有高精度、快速、环境适应性强等特点,新一代运载火箭利用该技术实现了智能化无人值守瞄准。

This paper introduces an aiming technology for new generation launch vehicle based on machine vision. A camera is integrated on a collimator, which is used for collecting the aiming object on the vehicle. Machine-vision image identification algorithm, including gray level transformation, morphology analysis, OCR algorithm and so on, is used to identify the images and measure the position information of aiming object on the launch vehicle real-time which relatives to aiming optical-axis. This scheme has advantages of high precision, rapid and strong environmental adaptability. The scheme has been used for the intelligent unattended operation at aiming system of new generation launch vehicle.
