ToF cameras can generate instant 3D point clouds. The outstanding advantages are that they are compact and inexpensive, not as complicated as other 3D cameras, and it is easy to distinguish objects in the scene. Besides, ToF cameras require neither contrast nor additional light, and works as objects pass by.
ToF sensor technology systems typically rely on emitting high-energy light pulses within a very short time window. It has the following advantages:
Single-point ToF sensor is mainly used to accurately measure the distance of objects, obstacles, walls or ground around the robot, and assist the drone or robot to determine the terrain and position, so as to achieve the role of landing, hovering or obstacle avoidance. DOMI ranging sensor has accurate measurement, stable output data and fast measurement, which is very suitable for the field of drones and industrial robots.
In the smartphone market, ToF camera solution has frequently appeared in many smartphone products, and has quickly become the mainstream solution in the field of 3D vision. In fact, major application markets are showing increasing demand for 3D depth vision technologies such as ToF cameras, among which machine vision applications are the most common.
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.
