What is the situation between LiDAR and pure vision in 2024?

With the rapid development of technology, autonomous driving technology has become an important trend in today's automotive industry. Among them, LiDAR and pure vision, as the two main autonomous driving perception technologies, are undergoing unprecedented changes and competition. This article will conduct an in-depth analysis of the current status of LiDAR and pure vision technology in 2024, and look forward to their future development trends.

1、 The rapid development of LiDAR technology

Lidar, as an advanced remote sensing technology, accurately measures key information such as the position and velocity of target objects by emitting laser pulses. In recent years, thanks to the rapid development of ultra short pulse lasers, high-sensitivity detection, and high-speed data acquisition technology, LiDAR has shown great potential in multiple fields such as intelligent driving, robotics, meteorological observation, geographic mapping, drone navigation, and virtual reality with its excellent measurement accuracy, spatiotemporal resolution, and broad detection range.

In the field of intelligent driving, LiDAR is mainly used for autonomous navigation, obstacle recognition, and path planning. As car companies accelerate the deployment of advanced intelligent assisted driving systems (NOA), LiDAR has become a key sensor to enhance user experience. Data shows that as of 2024, the number of standard LiDAR models on the market has significantly increased, and at the same time, the shipment volume of LiDAR has also shown explosive growth. This is not only due to the continuous advancement of its technology, but also to the sustained decrease in costs. Leading LiDAR manufacturers are further optimizing their cost structure, promoting the widespread application of LiDAR technology in more vehicle models such as electric vehicles.

2、 The continuous evolution of pure visual technology

The pure visual autonomous driving solution mainly relies on image data captured by cameras, processed and analyzed using deep learning algorithms to achieve environmental perception and decision-making. This scheme simulates the human visual system and has a high degree of natural adaptability and flexibility. Tesla CEO Elon Musk, as a staunch supporter of pure visual solutions, has repeatedly emphasized the future potential of this technology.

The pure visual solution has significant advantages in cost control, with relatively low camera costs, and with large-scale production, its price is expected to further decrease. In addition, companies such as Tesla that adopt pure visual solutions have accumulated a large number of high-quality video clips and continuously trained and optimized algorithms to improve the perception accuracy and reliability of the system. However, pure visual solutions also face some challenges, such as limited perceptual ability under adverse weather conditions, and maintaining data consistency and accuracy.

3、 Comparison and Fusion of Lidar and Pure Vision

Lidar and pure vision have their own advantages and disadvantages. Lidar can obtain accurate three-dimensional environmental information and has the characteristics of all-weather operation and fast response, but its cost is relatively high and its technical complexity is also high. Pure visual solutions are known for their low cost and high natural adaptability, but may be affected to some extent in harsh weather conditions.

Nevertheless, the auto drive system in the future may adopt the fusion of multiple sensors, combining the advantages of laser radar, camera, millimeter wave radar and other sensors, to improve the overall performance and safety of the system. Through multi-sensor fusion, the shortcomings of a single sensor can be compensated for, and the redundancy and perception ability of the system can be improved. For example, some domestic car manufacturers have adopted laser radar fusion sensing solutions, combining multiple sensors to achieve more accurate environmental perception and decision-making.

4、 Future Development Trends and Prospects

With the continuous advancement of technology and the expansion of application fields, both LiDAR and pure vision technology will play a more important role in the future. Lidar will be widely used in high-end vehicles and complex environments due to its high precision and reliability. Pure visual solutions, on the other hand, occupy a place in the mid to low end market and specific scenarios due to their low cost and high flexibility.

Meanwhile, with the continuous development of deep learning and artificial intelligence technologies, autonomous driving algorithms will have more room for optimization. By continuously training and iterating the model, the perception accuracy and decision-making efficiency of the system can be improved. In addition, the breakthrough in chip technology will also provide stronger computing support for the auto drive system, so as to better cope with complex data processing needs.

Looking ahead to the future, LiDAR and pure vision technology will learn from each other and integrate for development. The boundary between the two will become increasingly blurred, and more innovations will emerge, driving the continuous development of autonomous driving technology. We have reason to believe that in the near future, autonomous driving technology will bring a safer, more convenient, and comfortable travel experience to human society.

epilogue

In summary, the laser radar and pure vision technology in 2024 are in a golden period of rapid development. Both have their own strengths and are constantly improving through mutual learning and reference. With the continuous advancement of technology and the expansion of application fields, they will play an increasingly important role in the field of autonomous driving. We have reason to expect that future autonomous driving technology will become more mature, intelligent, and reliable, contributing more wisdom and strength to the sustainable development of human society.
