A safety protection dining table based on gradient analysis

Abstract

The invention relates to a safety protection method. According to the method, a gradient analysis-based safety protective dining table is provided. The dining table comprises: a dining table frameworkcomprising a combined table top, a tilting table leg, a horizontal seat plate, a beam and a plurality of table legs, wherein the horizontal seat plate is connected with a plurality of middle parts ofthe table legs; a visible light camera for carrying out visible light shooting around the dining table to output corresponding images around the dining table; a curve matching device for connecting all edge pixels to obtain a plurality of closed curves, wherein a plurality of corresponding patterns are respectively segmented from a grayscale image on the basis of the closed curves, a signal thata baby exists is sent when a pattern with the degree of matching with a preset baby standard image exceeding the limit exists and otherwise, a signal that the baby does not exist is sent; and a protective telescopic transverse plate for stretching below the combined table top when the signal that the baby exists is received to facilitate the placement of the baby.

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.

Problems solved by technology

[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
