With the rapid development of industries such as artificial intelligence, robotics, and the Internet of Things, machine vision has an increasing demand for 3D depth perception capabilities. Traditional 2D machine vision is rapidly upgrading to 3D depth camera with higher accuracy.
At present, the mainstream 3D sensing technologies widely used in the market are structured light and ToF camera. Among them, 3D ToF camera has obvious advantages in long distance, low cost and small size. With the arrival of 5G, the application of ToF camera will be more.
There are already many smartphones with integrated ToF cameras, however, it is easy to overlook the role it plays in enhancing industrial and manufacturing processes, as well as construction and agriculture. Next, several areas of tof camera applications are introduced in detail.
Depth calculation of ToF camera is not affected by the grayscale and features of the surface of the object, and can perform 3D detection very accurately;
Compared with stereo cameras or triangulation systems, ToF cameras are small in size and are very suitable for some occasions that require lightweight and small cameras. ToF cameras can quickly calculate depth information in real time, reaching tens to 100fps.
In terms of 3D ToF cameras, DOMI has a wide range of technical application and development experience. With significantly improved accuracy and reliability, DOMI tof camera products help customers reduce operating costs, which are suitable for retail, security, healthcare, drones, Internet of Things
The biggest advantage of structured light is the highest depth accuracy, which can theoretically reach the micron level, and the ToF sensor can reach the millimeter level, which is sufficient even for face payment. The high accuracy of structured light also requires complex calibration, while the ToF sensor does not need.
ToF camera is a powerful solution that provides high depth accuracy for applications requiring high quality 3D information. There are many factors that need to be considered in order to ensure optimal performance levels. Factors such as modulation frequency, demodulation contrast
Advantage of ToF sensor technology is that its recognition distance is farther than structured light (about 0.4 meters to 5 meters), its anti-interference is strong, and each point can directly provide complete depth information, and the transmitted data is already available
At present, the mainstream application technology of 3D sensing is structured light and ToF. The two sensing technologies determine their different application fields in principle. We compare and analyze the application fields applicable to the two technologies in terms of measuring distance, depth accuracy, algorithm complexity, scanning and response speed, various environmental adaptability and hardware cost.
