The radar scanning effect is often seen in our daily lives. for example, if there is a radar function on Sina Weibo, it feels like someone nearby. There is only an animation similar to the radar scanning effect, and some well-known security software also has this radar effect. so I will take you to learn it here. First
Transmission DoorIdeas:Take the greedy thought.Consider each island as a center, with the radar range D as the radius, to find the x-axis of the left and right two intersections, the two intersections sandwiched between the need to place a radar, so that the problem is converted to an interval to pick points. When enumerating islands, record the location of the last rad

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 lidar is not much different. The following small series will introduce well-known laser
Description
Assume the coasting is an infinite straight line. land is in one side of coasting, sea in the other. each small island is a point locating in the sea side. and any radar installation, locating on the coasting, can only cover d distance, so an island in the sea can be covered by a radius installation, if the distance between them is at most d.
We use Cartesian coordinate system, defining the coasting is the x-axis. the sea side is abve x-ax

The position information of the secondary radar monitoring data is expressed in polar coordinates, which is determined by the distance from the target to the radar, the azimuth, and the air pressure height measured by the aircraft. In the display, You need to convert the polar coordinate data to the WGS-84 coordinate system, t

UI and functionality are two important factors for a good product, and many products tend to focus only on functional design and ignore the UI. In this "look-face" era, even if the product is very powerful, if the UI can not keep up with the pace, your products will be greatly discounted in the customer's mind.The security and monitoring of the project is often scanned, usually using a GIF image to indicate that the software is scanning, but if you want to change the style of the icon, you need
