摘要： A device is described that performs an image processing technique. The device includes a first camera and a second camera, which are responsive to distinct spectra of light, such as the visible light spectrum and the infrared spectrum. While the device is in a first position in an environment, the first camera captures a first image of the environment, and the second camera captures a second image of the environment. The device determines a single set of coordinates for the feature based on depictions of the feature identified in both the first image and in the second image. The device generates and/or updates a map of the environment based on the set of coordinates for the feature. The device can move to other positions in the environment and continue to capture images and update the map based on the images.

摘要： Embodiments include methods executed by a processor of a robotic device for selecting a frontier goal for autonomous map building within a space, including determining trajectory costs for the robotic device traversing from an occupied area to each of a plurality of available frontier goals, wherein the plurality of available frontier goals include positions within the space from which the robotic device is configured to collect information to autonomously build a map of the space, determining co-visibility costs for each of the plurality of available frontier goals, determining a frontier cost for each of the plurality of available frontier goals based on a difference between the trajectory cost and the co-visibility cost of the respective available frontier goal; and selecting one of the plurality of available frontier goals having a lowest determined frontier cost.

摘要： This disclosure provides systems, methods, and apparatuses for high dynamic range (HDR) processing. In one aspect, an example HDR processing device may process a first exposure frame and a second exposure frame during a first capture sequence. The device may also generate a first HDR image from the first exposure frame and the second exposure frame at an end of the first capture sequence. The device may also process a third exposure frame during a second capture sequence that at least partially overlaps in time with the first capture sequence. The device may also generate a second HDR image from the second exposure frame and the third exposure frame.

摘要： Methods, systems, and apparatuses are provide to perform automatic banding correction in captured images. For example, the methods receive from a plurality of sensing elements in a sensor array, first image data captured with a first exposure parameter, and second image data captured with a second exposure parameter. The methods partition first image data and second image data and determine values for each partition. The methods compute banding errors based on the determined values of the partitions for first image data and second image data. The methods also determine a banding error correction to one or more of first image data and second image data based on the banding errors. Further, the methods perform an automatic correction of the banding errors on one or more of first image data and second image based on the banding error correction.

摘要： The present disclosure relates to methods and devices for high dynamic range (HDR) processing. In one aspect, the device may generate multiple frames, each frame being generated through a line-based exposure at a camera image sensor. The multiple frames can have at least two different exposure times and have staggered line-based exposure times during the at least two different exposure times. Additionally, the device can obtain movement information associated with the camera image sensor from a gyroscope sensor. The device can also modify the multiple frames based on the obtained movement information from the gyroscope sensor. Moreover, the device can combine the multiple frames into a staggered HDR image. The device can also generate a de-warp mesh for each frame based on the obtained movement information from the gyroscope sensor, and each frame can be modified based on its corresponding generated de-warp mesh.
