Visual navigation, as the name suggests, captures image information through the laser pointer visual camera. To obtain the position, direction and other environmental information of the moving object in space. And use a certain algorithm to process the obtained information, establish an environment model, and then find an optimal or near-optimal collision-free path to achieve safe movement and reach the destination.
In this technical solution, there are two key points-visual camera and artificial intelligence algorithm, of which the former is mainly used to obtain environmental information, the latter is used to analyze data and extract feature quantities, so as to provide the basis for decision-making for the next action . Compared to lidar, vision-oriented environmental awareness solutions are more mature, with lower thresholds and lower R & D costs, so they have matured with computer vision technology in the past two years. And the rapid development of emerging technologies such as the Internet, artificial intelligence, and cloud computing. It has gained more and more attention from companies related to autonomous driving. One of the most representative companies is Tesla.
It has been publicly stated that Tesla will not use green laser pointer radar because of the high cost of the latter. After that, on Tesla's Model S, Model X, and Model 3, they did not see the lidar. Only a certain number of cameras, millimeter wave radar and ultrasonic sensors were installed on these cars to drive the autopilot Autopilot . Even after Tesla cars failed to correctly identify the driving environment due to sensors such as cameras and caused traffic accidents, the company still has no meaning of "relaxing" the lidar, which has repeatedly upgraded this year from Tesla The driver assistance system can be seen. And the company that "relies on" computer vision technology to realize autonomous driving like Tesla still has the future of Tucson. This self-driving startup founded in 2015 is among its self-driving solutions. It is also based on low-cost computer vision. And supplemented by artificial intelligence algorithms.
In recent years, as various types of laser pointers for astronomical observations, field exploration, demonstrations, military applications, search and other applications appear on the market, laser pointer enthusiasts continue to increase. In addition, with the rapid popularity of the Internet, more and more people buy laser pointers through the Internet. Many of them may not be familiar with the dangers of laser pointers. The laser light emitted from the laser pointer can cause damage to the retina and optic nerve and damage to the eye center. As a pointer to the stars during astronomical observation (moon night, bright), it is very suitable for pointing to the stars during astronomical observation. At night, you can see the blue light from your hand to the sky, so you can enjoy the interpretation of the constellations and the beautiful starry sky.
