摘　　要：可见光相机可被应用于空间目标监测,其拍摄的图像具有高分辨率、高清晰度和高质量等优点。基于可见光探测器CMV4000获取Bayer格式数据的特点,采用了颜色插值和白平衡等方法,实现了彩色图像的重建。通过对比和分析多种插值方法,选取基于梯度的插值算法和灰度世界法用于工程实现色彩数据的重建。用彩色板等目标在实验室、暗室等场景下对算法进行仿真测试。结果表明:基于梯度的插值方法和白平衡法可以有效地恢复彩色图像,可以在空间环境中获取高质量的彩色图像。The visible camera plays an important role in space security area,which has high resolution,high definition and high quality image.Based on the characteristics of CMV4000 detector,the paper introduces the color interpolation and white balance methods,which reconstructs color image.Through comparison and analysis,gradient-based interpolation algorithm and gray world method are availability for color data reconstruction.The results show that the gradient-based interpolation and the white balance method can effectively restore the color image,which can acquire high quality color image in space environment.
