Intel® RealSense™ Dynamic Target Tool displays a graphical chart on a phone screen for Intel® RealSense™ Dynamic Calibrator to calibrate the D400 series Intel® RealSense™ depth cameras. The chart consists of black and white bars and blocks with specific dimensions regardless of phone screen sizes, for example, the black and white bars in the middle are always 10 mm wide and its height is always integral number of 10 mm, i.e., 90 mm or 100 mm, etc. Intel® RealSense™ Dynamic Calibrator detects and analyzes the pattern and compares with the ground truths to calibrate the devices. Intel® RealSense™ Dynamic Target Tool and Intel® RealSense™ Dynamic Calibrator always work in pairs.
