Abstract
This disclosure describes techniques for a wireless charger to identify a device e.g., smartphone, wireless headset, smartwatch etc. that is placed on a charging surface and to automatically align the transmitter coil to the exact location of the receiver coil. When a device is placed on charging surfaces, cameras on the wireless charger captures images of the device. The image is processed to construct a three-dimensional model and identify the exact model of the device to determine the location of the receiver coil within the device relative to the charging surface. When the location of the receiver coil is determined, the transmitter coil is aligned by use of motorized arms and coils to achieve optimal charging performance and efficiency.
