Mechanisms for generating compressed images are provided. More particularly, methods, systems, and media for capturing, reconstructing, compressing, and rendering view-dependent immersive light field video with a layered mesh representation are provided.

Laser-enhanced visual simultaneous localization and mapping (SLAM) is disclosed. A laser line is generated, the laser line being incident on an object and/or environment. While the laser line is incident on the object, one or more images of the object with the laser line incident on the object are captured. The camera is localized based on one or more characteristics of the laser line incident on the object. In some examples, improved feature localization provided by the laser line provides more accurate camera localization, which, in turn, improves the accuracy of the stitched mesh of the object/environment. As such, the examples of the disclosure provide for improved camera localization and improved three-dimensional mapping.

An electronic device and a control method thereof are provided. The electronic device includes a camera, a camera flash, and at least one processor configured to control the camera to capture a natural light image and a depth image of an object, control the camera and the camera flash to capture an artificial light image of the object, obtain distance information from the depth image to generate a depth mask image, create a cluster mask image from the natural light image, obtain a flash image in which the illuminance of the natural light image has been removed from the illuminance of the artificial light image, obtain an optimization parameter based on the distance information, the depth mask image, the cluster mask image, and the flash image, and obtain three-dimensional topographic information and surface reflection information about the object based on the obtained optimization parameter.
