space**\r\n![problem_1](https://user-images.githubusercontent.com/43142075/45404076-c4840400-b65d-11e8-96a3-598c635ca0a6.JPG)\r\n![problem_2](https://user-images.githubusercontent.com/43142075/45404077-c4840400-b65d-11e8-89b5-f098db15e598.JPG)\r\nHello Git-Hub-Community,\r\n\r\nI made a short programm that should get me the distance between two points in space. To check the accuracy I made a \"chessboard\" where each edge is exactly 50mm long. In the programm I can choose a place near the edges and the \"GoodFeaturesToTrack\"-function provides the exact pixels. After that I meassured the distance to the points and used \"rs.rs2_deproject_pixel_to_point()\" to find the koordinates in the 3D-space. The distance from the D435 to the points is quite accurate but the distance between the pints is always about 40% further than it really is. So i get a distance of 70mm when meassuring the 50mm edges.\r\nIs there something wrong with the camera options?\r\n\r\nAt this example: https://github.com/IntelRealSense/librealsense/tree/master/examples/measure\r\nthere is a function to fill zero pixels and to choose the \"High Density\"-configuration. How is this possible in Python?\r\n\r\nThank you so much for your help! Be patient! I did not know the term \"Python\" two weeks ago.\r\n\r\nBest regards\r\nMatthias\r\n\r\nI attached my code and the pictures.\r\n![code_1](https://user-images.githubusercontent.com/43142075/45404731-715f8080-b660-11e8-8ba3-bacc03fd249d.JPG)\r\n![code_2](https://user-images.githubusercontent.com/43142075/45404732-71f81700-b660-11e8-862d-0fb2fe9351cf.JPG)\r\n![code_3](https://user-images.githubusercontent.com/43142075/45404733-71f81700-b660-11e8-93ec-00b1b5552556.JPG)\r\n\r\n\r\n\r\n\r\n\r\n"}}
