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

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
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
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
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

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
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
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

Single-line LiDAR has been widely used, such as sweeping robots, single-line can get things 2
Laser radar has been used in military field earlier, with the development of technology and the reduction of cost, the application of LiDAR has become more and more popular nowadays, so far the field of robot, unmanned aerial vehicle and unmanned driving is becoming an important application field of LiDAR. And the price of laser radar has always been the focus of concern to the industry, the price of import
Earlier, LiDAR was confined to government and military applications. As technology advances and the cost of LIDAR manufacturing is reduced, it is widely penetrated into industrial and commercial areas. But at present domestic laser radar and abroad, in the multi-line lidar there is still a certain gap, but applied to the service robot, sweeping robot

With the development of technology and the reduction of cost, the field of robot, unmanned aerial vehicle and unmanned driving has become an important application field of LiDAR in the field of laser radar.
There are many kinds of sensors in the field of robotics, including cameras, lidar, millimeter-wave radar, ultrasound, infrared and many other sensors. The features and advantages of each sensor are not
with many different types of main sensors. Each type of sensor has different advantages and disadvantages, so the sensor data from different sensors should be effectively fused. The sensors commonly used in unmanned driving are now available in the following categories.

The Gps/imu sensing system helps unmanned vehicles to self-locate by using global positioning and inertia update data up to the Hz frequency. GPS is a relatively accurate positioning sensor, but its update frequency
