Systems and methods of object detection in wireless power charging systems

A system for wireless power transmission, comprising:

• a radio frequency wireless power transmitter that is in communication with a video camera for capturing image data of at least a portion of a transmission field of the radio frequency wireless power transmitter, wherein the image data comprises a series of image frames;
• and
• one or more processors of the radio frequency wireless power transmitter configured to:
• detect motion of an object towards the transmission field by applying motion tracking analysis on the series of image frames;
• and
• send instructions to cause adjustments to transmission of one or more radio frequency power transmission waves by the radio frequency wireless power transmitter to a receiving electronic device based on the motion of the object, wherein the receiving electronic device uses the one or more radio frequency power transmission waves to power or to charge a power source used by the receiving electronic device.
