U.S. Patent 9,921,054
On March 20, 2018, Week 12, Number 1448-3, the United States Patent and Trademark Office published issued U.S. Patent Number 9,921,054. The patent was issued to Samsung Electronics. The patent was published for all patent attorneys to see as US 2014/0354784. It appears on first glance to show a camera shooting method for three dimensional modeling using multiple images.
The purpose of the invention appears to be using a shooting method for creating three-dimensional camera modeling. The camera senses a position of the electronic device, calibrates the sensors, and stores the position information as metadata for each captured image.
The patent claims provide, inter alia:
A shooting method for three dimensional modeling in an electronic device having at least one sensor for sensing position information and an image sensor for image capture, the shooting method comprising:
calibrating the at least one sensor;
obtaining position information used for the three dimensional modeling using the at least one sensor;
identifying a least number of required images to be used for the three dimensional modeling of a target object;
displaying a guide including a field of view of the image sensor and indicating an optimized position information of the image sensor for capturing an image based on the obtained position information and the least number of required images, wherein the optimized position information includes height information of the electronic device, relative angle information between the electronic device and the target object, and relative distance information between the electronic device and the target object;
capturing multiple images according to the least number of required images of the target object based on the displayed guide; and
storing the position information as metadata of each captured image.
FIG. 1 proivdes an electronic device that may include a control unit 110, a touchscreen 120, a camera module 130, a sensor unit 140, a communication unit 150, a storage unit 160, and an audio processing unit 170. The patent attorney referred to FIG. 4A describing for the inventor that when the user raises the electronic device 410 from the ground (reference plane) to a desired height, the acceleration sensor may sense the height of the electronic device 410 from the ground.
