1.ENVI (the environment for visualizing Images) and IDL (Interactive Data Language) are the flagship products of the US Exelis vis company.ENVI is a complete remote sensing image processing platform, its software processing technology covers the input/output of image data, calibration, geometric correction, ortho correction, image fusion, mosaic, cropping, image enhancement, image interpretation, image classification, knowledge-based decision tree classification, object-oriented image classifica
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.
(1) Gps/imu:
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

The essence of wisdom, Satori is not easy, enlightenment more difficult.

How Much did It Rain? Winner ' s interview:1st place, Devin AnzelmoAn early insight to the importance of splitting the data on the number of radar scans in each row helped Devin Anzelmo tAke first place in the What Much did It Rain? Competition. In this blog, he gets to details on the his approach and shares key visualizations (with code!) from the He analysis.351 players on 321 teams built models to predict probabilistic distributions of hourly rainf
1. Observed elements: allows you to view the daily weather conditions of all weather stations. The WEBGIS map displays multi-element display or single-element observation data (optional ), it can display and hide site information (station number and station name), and provides list data for query and statistics. It can also form a color spot map for rainfall, temperature, wind power, and air pressure.2. Radar Data: displays the latest

Step 5: Now we need to create new national flags, loading pictures, radar maps, and Eva comments that are often forgotten. Here we use the ready-made files, that is, to extract the original files of the game into the files required by the new country. We use xccmixer for extr
The main idea is to draw on other people's ideas, mainly as follows/*** For each island to be scanned, find out the range of radar that can be placed on the coast [Left,right], * Sort these intervals by left from small to large* From the right point of the first interval, place the radar, then retrieve the next interval sequentially,* If the next interval is completely within the range of the
of reflection. It is divided into two types: gas-medium and water-medium. The air-Medium is a sound-wave transmission medium, the transducer is placed above the water surface, reflected by the surface acoustic waves, according to the echo time can be calculated and show the water level. The instrument does not touch water body, completely free from the water sediment, velocity impact and aquatic plants and other adverse factors. The Shu Jie is to mount the transducer at the bottom of the river
and me Planes in air combat. After the British invented the radar, they found a big problem in application: on the radar screen, they couldn't figure out which planes are enemies and who are themselves. As a result, they installed the identification system (identificationfriendorfoe, IFF) on the plane and installed the corresponding identification device (secondary rad
There is an article on the Air Force's wing website that adds wings to pig. The title party is very serious. In fact, the content is very serious. It is about the inside and outside of the stealth plane. The first generation of the stealth aircraft was F-117's nikhthawk, which was indeed thunderous. It is hard to imagine that something like this can fly and fight. To some extent, it looks really a bit like a pig with wings.
The life of F-117 is also legend. At the time of its development, its co

System: Lane departure alarm sensor: Camera
When a vehicle leaves its driveway or approaches the edge of the road, the system emits sound alarms or action alarms (via a slight vibration steering wheel or seat). When the vehicle speeds exceed a certain threshold (for example, greater than 55 miles), the vehicle does not turn on the turn signal, and these systems will begin to play a role. When a vehicle travels, its position relative to the

FFT (Fast Fourier transformation) is a classic algorithm used for digital signal processing. Many people who have studied DSP or chip design know this algorithm. However, have you ever wondered why there are so many FFT operations in digital signal processing? Some may say that in order to analyze the signal spectrum. The problem below is to analyze the daily needs of the spectrum, such as mobile phone calls, radar measurement speed and direction, and

1: Two camera instances are displayed on one screen at the same time.
It is certainly possible to have multiple cameras at once. There are a couple things to know that will help with this:
-Cameras have a "depth" property. This determines which orderCameras will draw. The camera with the highest depth will draw on topOf the camera with the lowest.
-Clear flags are important when dealing with multiple cameras. ThisBasi
Data Distribution Management
Data Distribution Management is based on some requirements in simulation. For example, in the air defense simulation, the ground radar only needs to know the air condition data within a certain range, therefore, the simulation members of the aircraft only need to transmit the data in the specified region to the radar members according to the data requirements of the ground
: Cartographer[2] and cartographer_ros[3]. Cartographer is primarily responsible for processing data from radar, IMU and odometer and building maps based on these data, which is the cartographer theoryThe underlying implementation. Cartographer_ros is based on the ROS communication mechanism to obtain the sensor data and convert them into cartographer defined in the format passed to cartographer processing, at the same time the cartographer processing
