In recent years, lidar has not only been applied in many fields such as commercial service robots, unmanned vehicles, agv/amr, but also become one of the indispensable intelligent sensors in the era of "meta universe".
This paper will interpret the development and R & D application direction of domestic TOF lidar from the aspects of technical characteristics and market pattern.
First, what is lidar?
Lidar (English: lidar) is a radar system that emits laser beams to detect the position, speed and other characteristics of targets. Its working principle is to emit a laser beam to the target, and then process and code the received signal reflected from the target to obtain the relevant information of the target, such as target distance, orientation, and even shape parameters. In addition, it can calculate the target speed, attitude and other information to achieve the detection, tracking and recognition of the target.
Market development and current situation -- from triangulation ranging to TOF radar
Although the development of lidar technology has a history of nearly 50 years, it was basically monopolized by foreign enterprises in the early stage. The price of lidar products remained high and it was difficult to purchase, which curbed the rapid development of domestic automobile and robot driverless. In order to quickly break through the monopoly, major domestic lidar enterprises have invested a lot of resources in research and development, from triangle lidar to TOF lidar, and continue to push through the old to bring forth the new, helping the development of driverless.
Now, with the growing maturity of the concept of meta universe and the rapid development of 5g technology, more and more industries want to enter this immersive, lasting and decentralized digital world. In the future picture of the meta universe, lidar must play a decisive role. The application range of lidar may exceed today's imagination, which also puts forward higher requirements for lidar:
1. Ranging radius: higher ranging radius can meet the application requirements of larger scenes
2. Sampling rate and angular resolution: the higher the sampling rate and the smaller the angular resolution, the richer the environmental point cloud information can be provided for the robot
3. Scanning frequency: the higher the scanning frequency, the higher the dynamic performance, and quickly identify the environmental information
4. Accuracy: ensure the accuracy of environmental objectives
5. Ease of use: the ease of use of the upper computer enables users to develop and apply quickly and operate conveniently;
6. Stability: stable and reliable long-term operation, no wrong triggering, timely response and reliable performance;
7. Environmental adaptability: anti-interference effect on sunlight, dust, rain and vibration in different environments;
8. Cost performance: on the premise of meeting the above performance requirements, price is a very important factor, and the most suitable products with high cost performance are pursued.
Silan has always been growing together with customers. No matter how the industry develops, the cost-effective lidar will enhance our ability to perceive the world. Therefore, Silan technology will continue to innovate in the exploration of lidar technology, performance and cost compression, and empower the industry with the most advanced technology, the most stable performance and the ultimate cost performance.
Future - diversified lidar application scenarios
In addition to technical exploration, the application in multiple scenarios is also the top priority. As the world's largest logistics market, China's industrial economy is creating a new pattern and rapidly moving towards intelligence and green. By promoting the application of emerging technologies and intelligent equipment such as laser radar, it is a general trend to improve the automation and intelligence of logistics links such as warehousing, transportation, distribution and distribution. In addition, intelligent infrastructure and smart city have also become one of the emerging laser radar markets. It can be said that the demand for intelligence is expanding infinitely in different fields.
As one of the earliest companies in the world engaged in the exploration and R & D of autonomous robot positioning and navigation technology, Shanghai Silan technology has focused on the R & D of laser radar technology since 2009. From triangular ranging laser radar to TOF laser radar to mapping radar, Silan technology has made breakthroughs again and again. In the exploration of diversified application scenarios, Silan has never stopped. At present, Silan has designed solutions in AGV scenarios, computer room scenarios, health care scenarios, intelligent prevention and control scenarios, restaurant scenarios, hotel scenarios, medical scenarios and other different scenarios, which have been highly recognized by customers.
In the future, Silan technology will also continue to deepen the R & D and application of lidar, expand its advantages in R & D, production and manufacturing of lidar, improve the overall service and operation and maintenance capacity, increase industrial investment, constantly break through the technical blockade, and develop and progress with the times and industries.
