The present specification relates to a mobile robot system and a boundary information generation method for the mobile robot system, the mobile robot system comprising a signal processing device that comprises a receiving tag for receiving a transmission signal and a distance sensor, so as to recognize coordinate information about a spot at which the point of the distance sensor is designated on the basis of the reception result of the receiving tag and the distance measurement result of the distance sensor, thereby generating boundary information according to the path designated as the point of the distance sensor on the basis of the recognized coordinate information.

Mobile robot system and boundary information generation method for mobile robot system

Provided is an ultrasound imaging device and an operation method thereof. An embodiment of the present disclosure provides an ultrasound imaging device comprising: an ultrasound probe; a display unit; a memory for storing at least one instruction; and a processor for executing the at least one instruction stored in the memory, wherein the processor: image-processes an echo signal to acquire multiple ultrasound images; calculates suitability indicating, as a numerical value, whether the multiple acquired ultrasound images are suitable as input images for a diagnosis algorithm for diagnosing a lesion; displays the calculated suitability on the display unit; and determines an input ultrasound image, which is to be input into the diagnosis algorithm, among the multiple ultrasound images based on the suitability.

Ultrasound imaging device and operation method thereof

A mapping method of a lawn mower robot may include a first image mapping operation of generating a first travel image of a three-dimensional region based on an aerial image of a work target region, a first map displaying operation of dividing the first travel image into a mowing region and an obstacle region, converting the first travel image into a first travel map, and displaying the first travel map. The mapping method may include a first anchor displaying operation of recommending the number and installation locations of anchors on the first travel map, an anchor location determination operation of determining whether the anchors are installed at the installation locations, and a path generation operation of generating a travel path of the lawn mower robot on the first travel map. The mapping method may improve work efficiency of the lawn mower robot.

Mapping method of lawn mower robot

A mobile robot includes a traveling unit configured to move a main body, a LiDAR sensor configured to acquire geometry information, a camera sensor configured to acquire an image of the outside of the main body, and a controller. The controller generates odometry information based on the geometry information acquired by the LiDAR sensor. The controller determines a current location of the mobile robot by performing feature matching between images acquired by the camera sensor based on the odometry information. The controller combines the information obtained by the camera sensor and the LiDAR sensor to accurately determine the current location of the mobile robot.

Mobile robot and method of controlling the same

A mobile robot and a method of controlling the mobile robot are disclosed. The method includes acquiring an image of an inside of a traveling zone. The method further includes performing a point-based feature point extraction by extracting a first feature point from the acquired image. The method also includes performing a block-based feature point extraction by dividing the acquired image into blocks having a predetermined size and extracting a second feature point from each of the divided block-unit images. The method also includes determining the current location by performing a point-based feature point matching using the first feature point and performing a block-based feature point using the second feature point. The method also includes storing the determined current location in association with the first feature point and the second feature point in a map.

Mobile robot control method

A three-dimensional image processing apparatus and a method of controlling power of same are provided. The three-dimensional image processing apparatus may include a display, a three-dimensional image filter disposed a prescribed distance from the display to adjust optical paths of the displayed view images, a camera configured to capture an image of a user, an ambient light sensor, and a controller configured to control the view images, the three-dimensional image filter, or the camera. The controller may determine a position of the user based on the captured image and adjust a perceived three-dimensional view of the view images based on the determined position of the user. Moreover, the controller may control an operational state of the camera and the at least one process based on the determined position of the user or a detected amount of ambient light.

A portable sound equipment having a body curved in C-shape, the body including an elastic part, an earbud holder provided to the body, an earbud detachably attached to the earbud holder, the earbud including a sound output module configured to output sound, a main board situated within the body, the main board configured to control the sound output module by being connected to the earbud, a sound cable connecting the earbud and the main body, a rotation module located within the body between an end portion of the body and main board, the rotation module configured to have the sound cable wound on an outer circumference thereof, a bridge coupled with the body to cover one surface of the rotation module, a flexible board disposed along the bridge and having one side connected to the main board and another side coupled to a microphone.

Portable sound equipment

Disclosed is a display apparatus. The display apparatus includes a light source unit configured to output a visible light, a scanner configured to output a first projection image and a second projection image based on the visible light by implementing first direction scanning and second direction scanning, and a light path splitter configured to separate light paths of the first projection image and the second projection image from each other, so as to output the first projection image and the second projection image toward a first display area and a second display area respectively. The display apparatus is capable of projecting different images onto display areas.

Display apparatus capable of projecting different images on display areas

A three-dimensional image processing apparatus and a calibration method of the same are disclosed. A display device displays two or more view images. A three-dimensional image filter is disposed at the front of the display device. The three-dimensional image filter has transmission regions and non-transmission regions which are alternately arranged. A controller adjusts positions of the non-transmission regions of the three-dimensional image filter based on a current position of a user and a reference switch mode. Upon detecting a user action to request movement of the non-transmission regions, the controller changes the reference switch mode in response to the user action and adjusts the positions of the non-transmission regions of the three-dimensional image filter based on the changed reference switch mode.
