https://community.intel.com/t5/Software-Archive/Using-Realsense-F200-to-measure/m-p/1088777#M64502 <P>Hi, I want to use the f200 the measure the distance&nbsp;between two points.</P> <P>My idea is quiet simple. Transforming the color and depth stream to opencv Mat type, CV_8UC3 and CV_8UC1, respectively. Selecting two pixel in color image and then get the their pixel coordinates, and then transform them into&nbsp;world coordinate and finally get the Eucliden distance. What I don't know is the mapping way. Although there is a StreamCalibration function in PXCCalibration, but there is also a transform function StreamTransform to transform the camera coordinate to world coordinate, i want to know is Wc*R+T or (Wc+T)*R. And i also want to know mapping from depth image coordinate to world coordinate.</P> <P>Beacuse the similar case is only with the R200 in sample RF_EnhancedPhotography, I really puzzled about the problems above.</P> <P>Thank you for your patience&nbsp;and suggestion. &nbsp;</P> Mon, 08 Aug 2016 07:03:32 GMT linhuan_h_ 2016-08-08T07:03:32Z https://community.intel.com/t5/Software-Archive/Using-Realsense-F200-to-measure/m-p/1088777#M64502 <P>Hi, I want to use the f200 the measure the distance&nbsp;between two points.</P> <P>My idea is quiet simple.
