Abstract: The present disclosure relates to an image processing method, an electronic device and a non-transitory computer-readable storage medium, where the image processing method includes: obtaining a first image to be processed, and obtaining a first mesh; determining a first mapping relationship between the first image and the first mesh, and determining vertex pixel information of the first mesh based on the first mapping relationship and the first image; obtaining a target distortion parameter, and adjusting a position of each of vertices of the first mesh in a three-dimensional space based on the vertex pixel information of the first mesh and the target distortion parameter to obtain a second mesh; and generating a target image based on the second mesh.

Abstract: The present invention discloses a monolithic natural light homogenization lighting device and method based on lens and sawtooth grating, and the device can be used as lighting curtains, indoor shutters, window glasses and the like. The device includes a front surface and a rear surface in an array form, the first surface is a lens array, and the second surface is a sawtooth surface array; the outdoor natural light at a high angle is collected by the lens array surface, and transmitted to the sawtooth surface array through the intermediate medium made of the same material between the two surfaces, and then horizontally dispersed to the indoor space after being refracted by an inclined surface. The present invention can efficiently collect the natural light incident into the window, disperse the light evenly to all directions indoors, homogenize the indoor lighting, and effectively protect the indoor privacy. The device is thin and easy to mass produce, environmentally friendly and pollution-free.

Abstract: Provided is a combined monolithic uniform lighting device based on lenses and sawtooth gratings. The present invention aims to solve the problem that traditional light absorption curtains cannot ensure that the natural light at each lighting stage can be evenly scattered into a room, making it difficult to form an all-weather uniform sunshine effect. The device includes ten first thin light sheets, ten second thin light sheets, ten third thin light sheets, ten fourth thin light sheets, ten fifth thin light sheets, ten sixth thin light sheets, ten seventh thin light sheets, ten eighth thin light sheets, ten ninth thin light sheets and ten tenth thin light sheets, which are arranged in a matrix to form a daylighting matrix.

Abstract: The present invention discloses a natural light homogenization lighting device and method based on free-form surface and sawtooth grating, and the device can be used as lighting curtains, indoor shutters, window glasses and the like. The device includes a front surface and a rear surface in an array form, the first surface is a free-form surface array, the second surface is a sawtooth surface array, and the free-form surface array is used for collecting outdoor natural light, and transmitting to the sawtooth surface array through the intermediate medium made of the same material between the two surfaces; and the sawtooth surface array is used for deflecting the incident natural light to the indoor space after being refracted by an inclined surface. The present invention can efficiently collect the natural light incident into the window, disperse the light evenly to all directions indoors, homogenize the indoor lighting, and effectively protect the indoor privacy.

Abstract: The present invention relates to a natural light homogenization lighting device, and particularly relates to a natural light homogenization lighting device based on combination of biconvex lenses and semi-transparent lenses. The present invention aims to solve the problems of low efficiency and poor lighting uniformity of light pipes, and possible damage to the original building structure in the process of installation and not conducive to the promotion and popularization of the existing solar energy conversion devices. The device of the present invention includes a positive lens combination and a positive half-lens combination; the positive lens combination and the positive half-lens combination are arranged side by side, the positive lens combination is located outdoors, and the positive half-lens combination is located indoors. The present invention belongs to the technical field of lighting systems.
