代码说明:

  将一个512×512的lena.bmp图像进行DCT变换,对得到的DCT系数按8×8块进行分层(分三层),重组填充得到新的系数矩阵,结果发现原图像的能量集中在了新图像的左上角低频部分。(The lena.bmp an image of 512 × 512 is subjected to DCT transform, the DCT coefficients obtained by layering 8 × 8 block (of three), to obtain a new recombinant filling coefficient matrix, the energy of the original image is found concentrated in upper left corner of the low-frequency part of the new image.)

    利用透镜成像理论建立摄像机数学模型, 提出了一种线性求解摄像机内外参数的方法。该方 法特点是采用主动发光的光点阵列标定靶,利用2D 标定靶的精确移动来实现基于3D 立体靶标的摄像 机标定的算法。(Lens imaging theory using mathematical models set up the camera, a camera inside and outside the parameters for solving linear approach. The method is characterized by active light-emitting points of light array calibration target, the use of 2D calibration target to achieve the precise mobile target based on stereo 3D camera calibration algorithms.)
