Even the United States, where agricultural modernization is extremely developed, has a headache for expelling birds. According to reports, Justin Meduri is a farmer with 175 acres of blueberry plantations. In order to catch birds, he even hired Falcons to work, but it turned out to be costly and unstable.
Subsequently, the Bird Control Group, headquartered in the Netherlands, brought the laser bird repellent method to North America. After deployment in the Blueberry Park, the effect was surprisingly good. When the birds are shot by the green laser pointer, they will leave very interesting, because the feeling is similar to the human being, and it is very unfriendly.
In addition to its remarkable results, BCG also said that the laser-controlled bird method is quieter than the traditional tweet box and even the shotgun. You know, birds like to be at 4 in the morning, that is, when most people are asleep.
However, the animal protection organization raised concerns that the laser pointer would harm birds, including destroying their vision. In this regard, Purdue University has embarked on relevant research. Last year, the number of laser bird repeller devices deployed in North America was 25, and this year is expected to increase to 100.
3D lidar can see through everything
It is reported that Chongqing Zhizhi will carry the fist products - 3D laser radar system and smart Internet of Things platform at the 2018 China International Intelligent Industry Expo.
The three-dimensional laser pointer has a wider application than face recognition. Face recognition is only for image recognition of portraits, but the three-dimensional lidar system can sense different objects around and accurately model.
According to reports, Chongqing Zhizhi's 3D laser radar system is based on laser point cloud data as the core of the original model. It can quickly create a 3D visualization model of complex and irregular scenes by acquiring spatial point cloud data.
It uses a unique tilted elliptical scanning technology to obtain three-dimensional information on the side of the facade object. It can scan the ground area from different angles even in densely populated areas. It is the only laser radar in the world that can achieve 100% effective frequency. system.
At present, the laser radar system equipment can be divided into two types of measurement and navigation.
