At present, there are several types of depth cameras, such as ToF camera, structured light, and laser scanning. Mainly used for robots, interactive games and other applications. Among these depth cameras, the ToF camera is the most widely used. Because the tof camera is compact, easy to integrate, and can be used indoors and outdoors, and can have a variety of detection distances
DOMI team has rich experience in 3D image, computer vision, image processing and sensor fusion technology. our tof camera, tof sensor, 3d depth camera products are suitable for many fields, and have received different customized needs from customers.our ToF camera products have been used in many fields, such as face recognition, people counting, smart home, AR & VR, logistics industry, etc.
Face recognition is a kind of biometric identification technology based on human facial feature information. A series of related technologies that use tof depth camera to collect images or video streams containing faces, and automatically detect and track faces in the images, and then perform face recognition on the detected faces, also known as portrait recognition and face recognition.
the ToF sensor has significant advantages in practical applications. For example: post-processing is not required when calculating the depth of field after the picture is captured, which can avoid delays and improve performance.
In addition to iToF series and dToF, DOMI also has RGB camera module series, which can meet customers' different application requirements from high performance to low cost. DOMI tof camera is widely used in various fields, such as Face recognition, 3D reconstruction, AR/VR, Robotics navigation, Volume measurement etc.
Compared with other stereo camera measurements, such as triangulation systems, binocular stereo cameras, ToF cameras are small in size and have excellent accuracy, which is very suitable for some scenarios that require lightweight and small cameras, such as smartphones, smart door locks,
ToF sensor can perform 3D imaging by sensing the distance of multiple points. Generally, objects within 5 meters of the sensor can be detected, and even further objects can be detected by the pattern lighting system
ToF camera technology transmits continuous infrared light pulses of a specific wavelength to the target, receives the light signal returned by the object to be measured through a specific sensor, and calculates the flight time or phase difference of the light round trip to obtain the 3D depth information of the object to be measured.
In the previous article, we introduced the respective advantages of structured light and ToF camera, including the comparison of depth accuracy, sensitivity, etc. The difference between these two schemes may cause the application fields of the two to be different, and there is no such thing as mutual substitution relationship. There are also some application areas where both can be used.
The advantage of the ToF chip is that the depth information can still complete traditional applications such as segmentation, marking, recognition, and tracking of target images. After further processing, it can complete applications such as 3D modeling, and can quickly complete target recognition and tracking.
