Manual Rotation and Translation

Manual rotation and translation tool is used to translate and rotate a single point cloud file. Rotate and translate the point cloud file in the user-interface, and the software will automatically calculate the transform matrix. After applying this transformation, the transformed result will be generated.

Note: To activate this function, there are at least one window other than profile window, and at least one point cloud file being opened in the software.

Steps

  1. Create a new window, and input the point cloud to be transformed and the reference point cloud (if there are any) in that window. Click the manual rotation and translation tool, and the following dialog window will popup.

In the table window, from left to right, each button is: open matrix, save matrix, start rotation and translation transformation, match data center, pause, resume to initial state, display transformation matrix, data transformation.

Lidar360 OpenOpen matrix: Input the existing matrix from external source. Please refer to the appendix for matrix format.
Lidar360 saveSave matrix: Save the current matrix information as a txt file.
Lidar360 DataAddMatch center: This function is applicable when there is a reference point cloud. By calculating the center of the reference point cloud and the point cloud to be transformed, this function can translate the point cloud to be transformed to the position of reference point cloud.
Lidar360 DataDelete Pause:暂停待处理数据的旋转和平移操作。
Lidar360 InteractiveTransformationResume: Resume the point cloud to be transformed to the initial status, and change the transform matrix to the identity matrix.
Lidar360 InteractiveTransformationApply transform matrix: After applying the transform matrix, the transformed point cloud will be saved to the original point cloud file.
TX: If this option is checked, it is allowed to translate the data in the direction of X axis. And the distance of translation will be displayed in delt X.
TY: If this option is checked, it is allowed to translate the data in the direction of Y axis. And the distance of translation will be displayed in delt Y.
TZ: If this option is checked, it is allowed to translate the data in the direction of Z axis. And the distance of translation will be displayed in delt Z.
Rotation: There are four options, X, Y, Z, and XYZ. If the X or Y or Z option is checked, the rotation about the checked axis is allowed. If the XYZ option is checked, the rotation about all the axes is allowed.
