Introduction
Cloud and aerosol Layer products document the spatial location of major geophysical variables, the surrounding meteorological conditions (such as temperature and pressure), and some of the optical properties of measurements and derivations. The optical properties of the direct measurement include the integral decay backward scattering, the volumetric offset ratio, and the attenuation of the total color ratio. The derived optical properties are properties that can only be obtained b

Application in Lidar
Recently, the main task is to read articles on the Application of Parallel Computing in lidar technology. Currently, it is rare to introduce parallel computing into the field of Lidar Data Processing. I have searched for three articles: a grid-based

The location of a particular position or obstacle is achieved.Read the LiDAR data and store it locally as test data. Each frame data has the deviation to the location information of the same obstacle. So we first sampled the points that needed to be located. During the sampling process, data loss is encountered, or multiple obstructions are det
September 23, the North Branch day painting Company in Zhongguancun Software Park held a product launch, launched two new LiDAR products, of which r-fans-32 is the history of the smallest 32-line LiDAR, C-rans is currently the highest number of local field laser radar.
R-fans is a navigation-based LiDAR developed by North Dakota for autonomous driving, intellige
FromCSKLow-cost 3D compaction. Very impressive!
Before introducing the principles, we will first give you some 3D models and demonstration videos after scanning, so as to give you an intuitive understanding.

The initial implementation of the dry tracking, and using dots to mark the obstacles80780205During the test, when there are two obstacles overlapping with the radar scan ray, the information of the obstacle which is far away from the teaching is lost. That is, the data is re-detected when no data is obtained and does not overlap. However, due to the loss of data frames, the algorithm is ju
1. Terrasolid Series Software Introductionterrasolid series software is the first commercial LIDAR data processing software, based on MicroStation development, running on the micorstation system, so users need to be familiar with the MicroStation operation can be very good use of it. It includes: Terramatch, Terrascan, Terramodeler, Terraphoto and other four important modules.2. Introduction to Features and performance2.1 loadingterrasolid s
1. Introduction to terrasolidThe terrasolid series is the first commercial LIDAR data processing software developed based on microstation and runs on the micorstation system. Therefore, users familiar with microstation operations can use it well. It includes four important modules: terramatch, Terrascan, terramodeler, and terraphoto.2. Introduction to features and Performance2.1 LoadThe terrasolid family of software can quickly load
The information that lidar obtains is the distance information with the surrounding object, and it is widely used in the field of mobile robot, especially autonomous mobile robot, so let's start with the autonomous navigation of mobile robot.
Mobile robot navigation means that the mobile robot relies on the sensor to realize the collision-free motion from the starting position to the target position according to the criterion of time, shortest path or

It is a powerful set of remote sensing image processing software developed by scientists in the field of remote sensing using interactive Data language IDL (Interactive, Language
Phenomenon: LiDAR processes die at the first power-up program from the startCause: The program starts to set the output strength data to: true (default after power failure is: false), and then start reading strength data, but at this time the strength data is not ready, the strength of the function is not initialized some values, causing the program to exitProcessing: 1. Delay before reading the strength data2. Assigning an initial value to an error v
The Finder is a system program for MAC computers, some of which are similar to Windows-enabled resource managers. It's the "smiley face" we first saw on our Mac, and with it, we can organize and use almost everything on your Mac, including applications, files, folders, disks, and shared disks on your network, and you can see rich, high-quality file previews at the same time.Next, I will share with you some of the experience of using

The Finder can locate the target serverresource and effectively process the request.
1. Finder manages the entire lifecycle of the serverresource subclass The default Implementation of finder is to use gettargetclass () to obtain the name of the serverresource subclass stored in the targetclass attribute of the finder

Mac OS X: Disable and enable the connect to server option in the finder menu
This function can easily restrict user access to other networks for sharing. Of course, it must be used together with other functions to better implement this function.
By default, this option is enabled:
You can also disable:
It is easy to implement.Program, Enter the following command to disable
Defaults write com. Apple.
Display the complete path on the Finder title barTo be honest, it is a bit wrong to share such a basic but useful technique with you.As we all know, MacOS finder does not display paths. when you enter a folder, only the name of the current folder is displayed.Although you can click "show"-"Show path" in the menu bar of the finder to adjust the path bar, this will
Show Hidden Files in FinderMany Mac users know that Mac OS X is based on FreeBSD (UNIX. However, we found that many UNIX files and directories, such as/etc,/var, And/bin, were not found. In fact, these files and directories are all hidden by the system. One of Mac's design principles is that what you don't need to see or what you don't want to see will not be displayed to you. If you need to access or modify these files, you can only use the "terminal" and access the files through Unix commands.
How does the Mac change the Finder icon? How does mac change finder font size? The Finder fonts on the Mac system are too small, and the icons in the list view are too small to be able to browse the files, especially some pictures, only one by one. Below the Pepsi net small weave here for everyone to introduce the next method.
