Abstract
Techniques are described for calibrating a coordinate frame of a remote sensing sensor of a perception system of a machine with respect to a coordinate frame of the machine. An application of a mobile device, such as a smartphone, a tablet computing device, or a laptop, or a web service detects a visual fiducial tag and a feature of the machine in an image by using an optical sensor of a digital camera system. The fiducial tag detection provides the coordinate transformation between the mobile device and a housing of the remote sensing sensor, e.g., radar sensor, lidar sensor, sonar sensor, or camera. Detecting a feature of the machine, e.g., a traction component such as a wheel or track, a brake light, a headlight, a turn signal, or a logo, provided constraints for the transformation between the device and machine.
