How to calibrate RGBD depth camera?
Common RGB-D cameras with rough intrinsic and extrinsic calibration data are often unable to meet the accuracy requireme...
3D ToF camera can measure the distance directly. The figure below is a schematic diagram of the Phab2 pro mobile phone's rear 3D ToF camera measuring in three-dimensional space. In the past, 3D reconstruction of the human body or object required complex laser scanning equipment, which is still far from consumer-grade applications. With the development of technology, high-precision, small 3D ToF camera can easily and quickly complete scanning and 3D reconstruction work. This can greatly promote the development of technologies such as virtual fitting and 3D printing.Different from small-scale object reconstruction, larger-scale three-dimensional spatial map reconstruction is more difficult, and has always been the forefront of academic research. The key technology is called real-time positioning and map construction. SLAM is one of the core technologies of intelligent robots and AR. SLAM based on RGB-D depth camera has always been a research hotspot. With the improvement of 3D tof camera performance and the iteration of algorithms, high-precision real-time robust SLAM technology is becoming more and more mature.Emergence of 3D tof camera will further liberate hands and open up a new space for intelligent human-computer interaction. In addition to 3D reconstruction applications, it will go deep into more fields in the future to realize intelligent interaction in scenarios such as size measurement, behavior analysis, 3D modeling, face recognition, and assisted driving.
