Three-Dimensional Object Localization Using A Lookup Table

View page
US Patent:
20200034986, Jan 30, 2020
Filed:
Aug 12, 2019
Appl. No.:
16/538647
Inventors:
- Mountain View CA, US
Andrea Colaco - Mountain View CA, US
International Classification:
G06T 7/73
G06T 7/11
G06T 7/20
G06K 9/00
G06F 3/01
G06F 3/042
G08B 13/184
Abstract:
A process executes at an electronic system. The process identifies device characteristics of an imaging device that includes signal emitters and signal detectors. The process illuminates a field of view by signals from the signal emitters according to a modulation signal generated by the imaging device. At each of the signal detectors, the process obtains a response signal, and samples the response signals to form a response vector. The process obtains a lookup table corresponding to the modulation signal and the device characteristics. The field of view is partitioned into a 3-dimensional plurality of voxels, and the lookup table specifies, for each voxel, expected signals received by the signal detectors when the voxel is filled and the signal emitters illuminate the field of view according to the modulation signal. The process compares the response vector to the lookup table to determine which voxels are filled.

US Patent:
20190387202, Dec 19, 2019
Filed:
Aug 19, 2019
Appl. No.:
16/544447
Inventors:
- Mountain View CA, US
Andrea Colaco - Mountain View CA, US
Dongeek Shin - Cambridge MA, US
International Classification:
H04N 7/18
G06K 9/00
G06K 9/20

G06T 7/50
G06T 7/586
H04N 5/222
H04N 5/225
H04N 5/33
Abstract:
A method generates depth maps at a camera having illuminators, a lens assembly, an image sensing element, a processor, and memory. The illuminators operate in a first mode to provide illumination, the lens assembly focuses incident light on the image sensing element, the memory stores programs for execution by the processor, and the processor executes the programs to control operation of the camera. The method reconfigures the illuminators to operate in a second mode, where each of a plurality of subsets of the illuminators provides illumination of a scene separately. For each subset, the process activates the illuminators in the subset without activating illuminators not in the subset and receives reflected illumination from the scene incident on the lens assembly and focused onto the image sensing element. The measured light intensity values of the received reflected illumination at the image sensing element are transmitted to a remote server for processing.

US Patent:
20180314346, Nov 1, 2018
Filed:
Apr 27, 2018
Appl. No.:
15/964499
Inventors:
- Mountain View CA, US
Andrea Colaco - Sunnyvale CA, US
Luis Villaran - San Carlos CA, US
Chintan Trehan - San Jose CA, US
International Classification:
G06F 3/0346
G06F 3/01
G02B 27/01
H03K 19/177
Abstract:
Techniques of tracking a hand controller in a VR system involves detecting, by photodiodes in the hand controller, patterns of diffuse radiation generated by diffuse LEDs in the HMD. Such techniques can also include comparing the detected patterns to those simulated offline previously and represented in a lookup table (LUT). By looking up the detected patterns in the LUT, the VR system may determine the position and/or orientation of the hand controller with sub-millimeter accuracy. Some advantages of the improved techniques can be in the simplicity and/or low cost of the components without sacrificing accuracy in deriving the position and orientation of the hand controller.

The process illuminates a field of view by signals from the signal emitters according to a modulation signal generated by the imaging device.

The process obtains a lookup table corresponding to the modulation signal and the device characteristics. The field of view is partitioned into a 3-dimensional plurality of voxels, and the lookup table specifies, for each voxel, expected signals received by the signal detectors when the voxel is filled and the signal emitters illuminate the field of view according to the modulation signal. The process compares the response vector to the lookup table to determine which voxels are filled.

20180288389, Oct 4, 2018
Filed:
Mar 31, 2017
Appl. No.:
15/476836
Inventors:
- Mountain View CA, US
Andrea Colaco - Mountain View CA, US
International Classification:
H04N 13/02
G06T 7/70
H04N 13/00
G06T 7/521
Abstract:
A process executes at an electronic system. The process identifies device characteristics of an imaging device. The imaging device has signal emitters and signal detectors. The process determines a modulation signal for controlling the signal emitters to illuminate a field of view. The process partitions the field of view into a 3-dimensional plurality of voxels. According to the modulation signal and the device characteristics, the process generates unit response signals. Each unit response signal is associated with one of the voxels, and each unit response signal represents reflection from the voxel when the voxel is filled and reflects illumination generated by one of the signal emitters according to the modulation signal. The process samples the unit response signals to form unit response vectors. Each unit response vector corresponds to one of the plurality of voxels. The process then combines the unit response vectors to form the lookup table.

International Classification:
A61B 5/11
A61B 5/00
A61B 5/0205
Abstract:
In an implementation of the disclosed subject matter, a device may emit a first emission sequence of infrared radiation at a subject, and capture a first reflected sequence of infrared radiation reflected from the subject. The first emission sequence may be compared to the first reflected sequence, and, based on the comparison, a sequence of variations may be determined. The sequence of variations may be compared to signal pattern stored in a sleep profile for the subject. The subject may be determined to have exhibited sleep behavior based on the comparison of the sequence of variations to the signal pattern stored in the sleep profile. In response to determining the subject has exhibited sleep behavior, the device may capture a second reflected sequence of radiation reflected from the subject. A breathing rate of the subject and/or a heart rate of the subject may be determined based on the second reflected sequence.
