Patent number: 9531940Abstract: A liquid crystal lens imaging apparatus includes a lens group containing at least a liquid crystal lens, a drive circuit, an image collecting unit, and an image processing unit. The drive circuit is connected to the liquid crystal lens to drive the liquid crystal lens into an out-of-focus state or into an in-focus state. The image collecting unit is configured to collect light signal passing through the liquid crystal lens and to generate an image according to the light signal. When the liquid crystal lens is in the in-focus state, the image collecting unit generates an in-focus image of the light signal and, when the liquid crystal lens is in the out-of-focus state, the image collecting unit generates an out-of-focus image of the light signal. Further, the image processing unit is connected to the image collecting unit to receive both the in-focus image and the out-of-focus image and to process the in-focus image using the out-of-focus image to obtain a processed in-focus image as a final generated image.Type: GrantFiled: December 23, 2014Date of Patent: December 27, 2016Assignee: SHENZHEN MERCURY OPTOELECTRONICS RESEARCH INSTITUTEInventors: Mao Ye, Chunhui Cui, Rui Bao, Shuda Yu

Patent number: 9435911Abstract: A visual-based obstacle detection method is provided. The method includes receiving image information of an environment containing a mobile robot captured by at least one visual sensor to obtain one of a three-dimensional space and a two-dimensional plane, and extracting and matching feature geometric primitives based on the received image information. The method also includes reconstructing coordinates of matched extracted feature geometric primitives and positions and orientations of the visual sensor and optimizing the reconstructed coordinates to obtain a calculation result, wherein the calculation result includes the feature geometric primitives, the positions and orientations of the visual sensor, as well as visible constraint relationships between the feature geometric primitives and the positions and orientations.Type: GrantFiled: April 29, 2015Date of Patent: September 6, 2016Assignee: SHENZHEN MERCURY OPTOELECTRONICS RESEARCH INSTITUTEInventor: Shuda Yu
