Patents by Inventor Chunping LIU

Chunping LIU 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: 20230123118
    Abstract: An embodiment of the present invention provides a picture processing method in an embedded system. The picture processing method includes: performing a bit setting operation on an input/output register corresponding to a communication GPIO port of a camera module in the embedded system, so as to improve a picture collection speed of the camera module; compressing a collected picture using a preset picture compression algorithm and transmitting the compressed picture to a picture preprocessing unit in the embedded system; and filtering out, by the picture preprocessing unit, a picture background using a preset filtering algorithm to obtain picture features of a target object in the picture. With the picture processing method, requirements for an occupied memory resource are balanced while a picture collection speed and a picture data processing speed are increased.

  • Publication number: 20220044172
    Abstract: A method for operation management of aircrew includes: determining multiple initial duties composed of a number of flights according to an obtained flight schedule, determining multiple initial pairings each including a start half pairing and an end half pairing according to the initial duties, selecting multiple candidate pairings from the multiple initial pairings with the objective of minimum total flight operating cost, and determining a roster schedule of the aircrew with a series of pairings according to the candidate pairings and obtained information of the aircrew. A process of generating the pairings includes: first, building two half pairings, namely a start half pairing and an end half pairing, and then combining the half pairings with tasks of an other base to flexibly connect the pairings of the other base through half pairing bridging.
