Abstract: An STL model slicing method includes: reading and loading an STL model; obtaining a first slice plane; according to a first set thickness, making the first slice plane be horizontally tangential to an STL model to obtain a first profile curve, which is a profile curve of a tangent plane of the STL model and the first slice plane; determining whether the profile curve contains a physical portion of the STL model; if the profile curve contains the physical portion of the STL model, filling the physical portion with white to obtain a white portion; determining a non-physical portion in the profile curve according to the physical portion; filling the non-physical portion with black to form a mask of the tangent plane; and projecting the mask onto a liquid photosensitive resin by means of a first 3D printer, and then curing the white portion to be a first cured profile.

Abstract: An embodiment of the present invention provides a picture processing method in an embedded system. The picture processing method includes: performing a bit setting operation on an input/output register corresponding to a communication GPIO port of a camera module in the embedded system, so as to improve a picture collection speed of the camera module; compressing a collected picture using a preset picture compression algorithm and transmitting the compressed picture to a picture preprocessing unit in the embedded system; and filtering out, by the picture preprocessing unit, a picture background using a preset filtering algorithm to obtain picture features of a target object in the picture. With the picture processing method, requirements for an occupied memory resource are balanced while a picture collection speed and a picture data processing speed are increased.
