Patents by Inventor Zhichang (Henry) Yan

Zhichang (Henry) Yan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20210354706
    Abstract: Sensors coupled to a vehicle are calibrated using a calibration environment that includes sensor targets, and optionally includes a motorized turntable that rotates the vehicle to different orientations, with the sensors capturing data at each orientation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, determines whether characteristics such as lighting or positioning of the representations of the sensor targets are optimal for calibration, sends signals to lighting systems or motorized target movement systems if necessary to adjust those characteristics, and calibrates the sensor based on the representations of the sensor targets.

  • Patent number: 10796453
    Abstract: Sensors coupled to a vehicle are calibrated using a dynamic scene with sensor targets around a motorized turntable that rotates the vehicle to different orientations. The sensors capture data at each vehicle orientation along the rotation. The vehicle's computer identifies representations of the sensor targets within the data captured by the sensors, and calibrates the sensor based on these representations, for example by generating a transformation based on mapping positions of these representations in the data to known positions of the sensor targets, such as to correct lens distortion, the transformation applied to post-calibration sensor data.
