Both 3D structured light and ToF sensor solutions are similar to radar detection methods, relying on additional light sources to detect depth of field, and associated hardware for specific processing of this special light source. By not having to deal with complex natural light, these hardware can obtain depth-of-field data more efficiently and accurately, independent of real-world lighting conditions. So what are the advantages of 3D structured light and ToF sensor?
ToF camera can increase the speed of the packaging sorting process, make the sorting work in the logistics industry more intelligent, and can guide the relative position between the robotic arm and the product and the best pick-up point for the product. ToF camera is an ideal solution for smart logistics.
ToF camera is a very advanced ranging device that replaces a standard point-by-point laser beam with a pulse or flash of light for full spatial perception. ToF cameras can sense the time it takes for light to return from any surrounding object, combine it with video data, and create a real-time 3D image. It can also be used to track facial or hand movements
ToF camera has fast response speed, high precision, and is not easily disturbed by ambient light. Compared with 2D cameras, ToF camera is more suitable for face recognition because it does not require additional fill light and the active lighting mode determines that it can be used in some special environments
ToF camera measures the distance from the object to the camera by measuring the time from when the light is emitted to when it is reflected back to the camera through the object.
ToF camera is used in machine vision, which can improve the detection accuracy and speed, and effectively avoid the advantages of subjectivity and individual differences brought by manual detection. The tof camera occupies an increasingly important position in the field of industrial inspection. The characteristics of tof camera used in machine vision are automation, objectivity, non-contact and high precision.
ToF camera is used in the industrial field and can realize many machine vision functions, such as measurement functions. ToF camera can automatically measure the appearance size of the product, such as the measurement of the outline, aperture, height, area and other dimensions.
We use vision to see the world. About 80% of the information that people obtain from the outside world is obtained visually. use of tof camera for 3D machine vision is a way for machines to perceive visual information. There have been many cases of tof camera applied to 3D machine vision. use of tof camera can improve the practical application of products.
There are many cases where tof camera is used in the field of machine vision, such as robot vacuum, food delivery robots, industrial robots, etc. tof camera can convert image signals into digital signals; the image processing system performs various operations on these signals to extract the target's features, such as area, quantity, width, height, etc.
With the continuous development of science and technology, face recognition technology has been widely used in many fields such as finance, security, inspection, education, and medical care. At the same time, it also ushered in the transformation from two-dimensional to three-dimensional. Compared with 2D face recognition, the advantages of 3D face recognition using tof camera are more obvious.
