ENVI IDL: How to reproject MODIS GRID data?

01 Description It contains three pro processes, of which modis_grid_warp is the main program, modis_grid_geo_transform and img_warp are regular pro processes, and read_h4 is a custom function. modis_grid_geo_transform generates a projection coordinate data set based on corner information and converts it into a longitude and latitude data set, and img_warp performs reprojection (GLT correction) based […]

The point cloud displayed in rviz is perpendicular to the grid. Convert the saved pcd file to a point cloud and display it in rviz, and use octomap_server to convert the point cloud map into an octree map and an occupied raster map.

Article directory Problem: Point cloud is perpendicular to grid background Solution: Transform the point cloud coordinates, rotate 90 degrees around the x-axis, and point the z-axis upward. Convert pcd to point cloud and display point cloud image in RVIZ Create launch rviz display Problem: Point cloud is perpendicular to the grid When using lego-loam to […]

Model selection and tuning (grid search and cross-validation)

1. Why cross-validation is needed Cross-validation purpose: To make the evaluated model more accurate and credible 2. What is cross validation Cross-validation: Divide the training data obtained into training and validation sets. Take the following figure as an example: the data is divided into 4 parts, one of which is used as the verification set. […]

Direct3D Grid (1)

Create grid We can use the D3DXCreateMeshFVF function to create an “empty” mesh object. An empty mesh object means that we specify the total number of patches and vertices of the mesh, and then use this function to The vertex cache, index cache and property cache allocate appropriately sized memory, which can then be manually […]

Direct3D Grid (2)

ID3DXBuffer The ID3DXBuffer interface is a generic data structure. This interface is used by the D3DX library lock to store data in a continuous memory block. This interface has only two methods. In order to maintain the versatility of the interface, the interface uses a void type pointer, so the cache needs to be cast […]
