Abstract: Disclosed are a method for correcting a projected image, a projection device, a capturing device, and a medium. The method includes: forming a test image through projection onto a target reflecting surface, to acquire a template image, wherein the template image is an image generated by capturing the test image when an edge of the test image is located within a preset capturing region, the capturing region is a region formed between a preset first capturing frame and a preset second capturing frame, and the second capturing frame surrounds a periphery of the first capturing frame; acquiring a position correction value for the projection onto the target reflecting surface based on a deviation between the template image and a preset standard image; and based on the position correction value, correcting a target image to be projected by a projection device, to acquire a corrected image projected on the target reflecting surface.

Abstract: The present disclosure provides a photographic exposure method for a self-moving device. The method includes: detecting, based on a preset rule, brightness information of a target region in an image; adjusting a exposure parameter in response to the detected brightness information not meeting a preset condition; and performing, based on the adjusted exposure parameter, exposure in a localized region during image acquisition, the localized region including at least the target region.

Abstract: A method for displaying a color three-dimensional map, includes: acquiring initial color three-dimensional map information of a space where a robot is located, where the space where the robot is located represents a space corresponding to a region detectable by a robot sensor; completing the color three-dimensional map based on the initial color three-dimensional map information to perform inference-based completion on structural and color information of a region undetected by the robot sensor; and displaying the completed color three-dimensional map obtained after the completing.

Abstract: A furniture hinge device capable of implementing wide range loading, comprising a housing and a fixing plate. A linkage assembly is provided between the housing and the fixing plate. A lever assembly and a power assembly are provided on the housing. The power assembly comprises a primary spring and a secondary spring. Positioning ends of the primary spring and the secondary spring are respectively mounted, from bottom to top, at a lower swinging end of the lever assembly. An adjustment assembly is provided on connection ends of the primary spring and the secondary spring. A fixing part of the adjustment assembly is fixedly mounted on a side plate of the housing. Adjustment parts of the adjustment assembly are respectively rotatably connected to the fixing part of the adjustment assembly and are connected to adjustment ends of the primary spring and the secondary spring.
