Electric power operation safety area defining method based on polygon internal and external point judgment

Abstract

An electric power operation safety area defining method based on polygon internal and external point judgment belongs to the technical field of computer graphics and electric power safety monitoring,and is mainly completed by two parts, namely partition of a target polygon and target point internal and external judgment of a small area after partition. The improved algorithm is combined with human body detection to be applied to border-crossing behavior detection of electric power operators. The safety zone boundary in the operation field is taken as a polygon in an algorithm, human body detection is carried out on the electric power operator, one point is extracted from the detected framework, and whether the point is in the polygon or not is judged so as to judge whether the operator crosses the safety zone or not. The problem that an operator enters dangerous areas such as a high-voltage area can be solved, the practicability is high, and the safety of electric power operation canbe guaranteed.

Description

technical field [0001] The invention belongs to the field of computer graphics technology and electric power safety monitoring technology, and in particular relates to a method for defining a safe area of ​​electric power operation by using a polygon inner and outer point judging algorithm. Background technique [0002] In recent years, the scale of the power grid has continued to expand, and engineering safety has become a top priority. In order to meet the ever-increasing security requirements, the electric power operation safety monitoring system has been well developed in the power grid industry. The power operation safety monitoring system uses the Internet of Things technology to obtain real-time data such as on-site video during operation, and then extracts and analyzes it to achieve the purpose of reducing the probability of accidents. The content of its extraction process includes target detection and cross-border detection of the characters in the acquired video. ...

Problems solved by technology

However, the time complexity of the traditional algorithm is unstable. When each node of the BSP tree has only the left subtree or the right subtree, the tree structure will degenerate into a linked list, and the time complexity will increase, which is poor in usability in actual projects. Therefore, the shortcomings of the traditional algorithm are improved and then applied to the definition of the safe area of ​​​​electrical work.
