Safety protection dining table based on gradient analysis

Abstract

The invention relates to a safety protection type dining table based on gradient analysis, comprising a dining table structure, comprising a combined table top, inclined table legs, a horizontal seatplate, a cross beam and a plurality of table legs, wherein the horizontal seat plate is connected with a plurality of intermediate parts of the plurality of table legs; A visible light camera for photographing the periphery of the dining table to output a corresponding image of the periphery of the dining table; A curve matching device for connecting all the edge pixels to obtain a plurality of closed curves, respectively segmenting corresponding patterns from the grayscale image based on the plurality of closed curves, and emitting an infant presence signal when there is a pattern whose matching degree with a preset infant standard image exceeds a limit, otherwise, emitting an infant absence signal; A protective telescopic cross plate for deploying from below the modular desktop to facilitate placement of the infant upon receipt of the infant presence signal. By the invention, the dining table can be more suitable for infant targets.

Description

technical field [0001] The invention relates to the field of safety protection, in particular to a safety protection dining table based on gradient analysis. Background technique [0002] The dining table can be divided into: round solid wood dining table, rectangular solid wood dining table, square solid wood dining table, polygonal solid wood dining table and so on according to the shape. Generally, during meals, if there are many people eating, most of them use round tables or oval tables. Square dining tables and rectangular dining tables are generally suitable for four people to eat, and each of the four people holds one side, and it is convenient to eat. Contents of the invention [0003] In order to solve the technical problem that the existing dining table cannot be used for baby targets, the present invention provides a safety protection dining table based on gradient analysis.

[0003] In order to solve the technical problem that the existing dining table cannot be used for baby targets, the present invention provides a safety protection dining table based on gradient analysis. By detecting the results of babies around the dining table, the corresponding alarm and protection operations are determined to improve the usability of the dining table. , wherein, based on the preliminary detection results of the number of targets in the image, the timing and frequency of contrast enhancement processing of the high-definition image are determined, thereby avoiding the waste of computing resources; Based on the region division strategy of the image, high-precision acquisition of the target image after stripping the background; using background matching to determine whether the output image of the visible light camera has a position due to the misalignment of the visible light camera The change of the camera is particularly important, and a self-adjusting unit is also built in the visible light camera to restore the position automatically according to the change of the position
