A system renders a primitive of an image to be displayed, for instance in a mobile 3D graphic pipeline, the primitive including a set of pixels. The system locates the pixels in the area of the primitive, generates, for each pixel located in the area, a set of associated sub-pixels, borrows a set of sub-pixels from neighboring pixels, subjects the set of associated sub-pixels and the borrowed set of pixels to adaptive filtering to create an adaptively filtered set of sub-pixels, and further filters the adaptively filtered set of sub-pixels to compute a final pixel for display. Preferably, the set of associated sub-pixels fulfils at least one of the following: the set includes two associated sub-pixels and the set includes associated sub-pixels placed on pixel edges.

A system and method of measuring 3D points is provided. The method includes defining a first frame of reference with a mobile computing device. A second frame of reference is defined with a mobile 3D measurement device. The mobile computing device is moved within a predetermined distance of the mobile 3D measurement device. The first frame of reference and the second frame of reference are registered when the mobile computing device is within the predetermined distance from the mobile 3D measurement device. The mobile computing device is moved along a path to define a trajectory in the first frame of reference. The trajectory is transmitted to the mobile 3D measurement device. The mobile 3D measurement device is moved along the trajectory in response to receiving the trajectory. 3D coordinates of point on an object are acquired with the mobile 3D measurement device.

The invention relates to the technical field of tunnel monitoring and three-dimensional measurement methods, specifically an error correction processing method for a tunnel point cloud model based on mobile three-dimensional laser scanning technology, which selects multiple points on the seams between rings and combines pixel Horizontal and vertical resolution, restore point coordinates, each seam can solve the corresponding three-dimensional angle deviation, find the nearest seam to any point in the point cloud, use the angle of the seam to correct the corresponding point, and After correcting the angle errors of all points, regenerate the tunnel tile map, and correct the point cloud, and then correct the angle deviation as shown in step B, to obtain an accurate tunnel point cloud model. Its advantages are: high precision, fast speed, automation, The utility model has strong practicability and can meet the requirement of tunnel convergence measurement.
