摘要:
The invention presents a system and method for obtaining object depth through digital signal processing. The auto depth-field capturing method for a camera includes the steps of a) taking plural images; b) estimating plural epipolar data of the plural images for obtaining a matrix describing motion and directional vectors; c) estimating a location data in response to the plural epipolar data and the matrix; d) rectifying the plural images corresponding to the plural epipolar data for obtaining plural rectified images; e) calculating the location data for obtaining disparity vectors of the rectified images; f) obtaining a depth map in response to the disparity vectors and the location data; and g) painting a 3D image in correspondence with the depth map. The depth estimation method of the present invention is fully automatic without change of the camera itself.
摘要(中):
本发明提出了一种通过数字信号处理获得物体深度的系统和方法。 相机的自动深度场捕获方法包括以下步骤:a)拍摄多个图像; b)估计所述多个图像中的多个对数数据,以获得描述运动和方向向量的矩阵; c)响应于所述多个对极数据和所述矩阵来估计位置数据; d)对与多个对数数据相对应的多个图像进行整流,以获得多个整流图像; e)计算用于获得整流图像的视差矢量的位置数据; f)响应于视差矢量和位置数据获得深度图; 并且g)与深度图相对应地绘制3D图像。 本发明的深度估计方法是全自动的,而不改变相机本身。
