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 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.
