一种从融合颜色信息和深度信息的PNG文件中提取点云数据的方法

A method of extracting point cloud data from PNG files fusing RGB and depth information

使用微软Kinect体感设备对物体三维信息构建时会产生大量的场景彩色信息和深度信息,可在Open CV框架下将Kinect视场下的信息保存为两张PNG格式的RGB图和深度图,为后续的物体三维构建提供原始的数据信息,这种方法使用比较繁琐。针对此问题提出了一种将颜色信息和深度信息融和到一张PNG文件中,隐藏深度信息到Alpha通道并在OpenFrame Works平台下实现了提取三维点云数据的方法。

A large number of RGB information and depth information will be produced for 3D information construction with Kinect sensor.RGB map and depth map will be saved as two PNG format using the OpenNI library,and it provides original data for 3D construction of the follow-up.It’ll be a little long-winded.In this paper,we proposed a method to integrate color information and depth information into a PNG file and hide the depth information to the Alpha channel to read the 3D point cloud information.And the method of extracting 3D point cloud data is implemented on the OpenFrameWorks platform.
