摘要： A wide-angle, high-resolution distance measurement device according to one aspect of the present disclosure comprises: a light source which emits structured light; a camera which forms an image by capturing reflected light, which is the structured light emitted from the light source and incident on the camera after being reflected by an obstacle; and a resolution correction lens which is disposed in front of the camera and corrects the reflected light which is reflected by the obstacle and incident on the camera, such that the resolution of the image formed by the camera is uniform irrespective of distance.

摘要： A method of acquiring distance information of an object by using a LiDAR apparatus includes: irradiating a first laser light of a first type toward surroundings of the LiDAR apparatus for a first time period; receiving a first reflected laser light of the first laser light reflected from a first object located around the LiDAR apparatus, by using an optical sensor of the LiDAR apparatus; irradiating a second laser light of a second type, which is different from the first type, toward the surroundings of the LiDAR apparatus for a second time period following the first time period; receiving a second reflected laser light of the second laser light reflected from a second object located around the LiDAR apparatus, by using the optical sensor; and acquiring an image frame including distance information representing a distance between the LiDAR apparatus and the first object and distance information representing a distance between the LiDAR apparatus and the second object, based on the first reflected laser light and the second reflected laser light.

摘要： Provided is a light detection and ranging (LIDAR) device. The LIDAR device includes: a light source configured to emit a first light beam; a photodetector configured to detect a second light beam, the second light beam being a reflected or scattered light beam of the first light beam reflected or scattered by an object; a diverging member comprising a reflective material configured to diverge the first light beam in various directions by rotating about a rotation axis; and a converging member including an optical element including one or more of a refractive and/or reflective material configured to converge the second light beam from the object and configured to cause the second light beam to be incident on the photodetector.

摘要： An electronic apparatus includes a processor configured to identify a first distance based on locations of first pixels that received the reflective light, and identify a second distance based on locations of the second pixels that received the reflective light, and calculate a difference between the first and second distances, and based on a distance acquired by the calculation and a moving distance of the electronic apparatus identified through the second sensor, identify whether the reflective light is reflective light reflected by an object or reflective light that was reflected on the object and then reflected again by another object.
