The measurement of centroid is very important for infrared imaging platform. The method for lightweight platform is not mature. In this paper, the development about the measurement of centroid is described. The structure and the requirement in testing of the lightweight infrared imaging platform are analyzed. According to the analysis, torque balance method is considered to be the best choice of testing the centroid of the platform, and it is proved right by the experiment. At last, the key points of the testing process are summarized.质心测量对于红外成像稳定平台十分重要，而针对轻小型稳定平台的测量技术并不成熟。介绍了质心测量技术发展概况，分析了轻小型红外成像稳定平台的结构特点和测试需求。根据平台特点和测试需求，经分析指出力矩平衡法比较适合平台质心位置的测量，并通过实验验证了这一观点。最后总结了在质心测量过程中需要注意的关键点。
