| 摘要: |
| 提出了一种利用Lytro相机光场图像进行双目立体测距的方法,首先对原始光场图像进行重编码获得宏像素水平排列的光场图像,由重编码图像提取出子孔径图像阵列并进行校正,相当于获得了相机阵列所拍摄得到的图像阵列。然后选取其中2个平行子孔径图像构成双目立体测距系统,通过matlab标定工具箱和OpenCV函数库进行联合标定、立体校正和立体匹配生成深度图像,对目标物体进行距离测量。实验结果表明,该方法的距离测量在精度范围之内,双目测距方法可以应用于通过微透镜阵列获得的子孔径图像上。 |

| Abstract: |
| We propose a binocular stereo depth measurement method based on light field images. Firstly, the original light field image was recoded to make the macro pixel horizontal. After recoding we obtained and rectified the subaperture images, which were similar to the image array acquired from the camera array. Then we chose two horizontal subaperture images to constitute the binocular stereo distance measurement system.Through matlab toolbox and OpenCV, the calibration, stereo rectification, stereo matching were completed to create the depth map. The experimental results and their analysis showpreliminarily that the precision of distance measurement is in the theoretical range and that the method of binocular distance measurement can be used on the subaperture images obtained from light field images. |
