Imaging method and system used in video monitoring

Abstract

The invention discloses an imaging method and system used in video monitoring. The method includes the following steps: acquiring images of the same to-be-monitored object in the same monitoring scenario to obtain monitoring image data under a plurality of viewing angles; conducting 3D information recovery on the monitoring image data, generating a 3D spatial image of the to-be-monitored object in the monitoring scenario, wherein the 3D spatial image includes a 3D point set including 3D spatial position information; conducting display converting processing on the 3D point set, generating display data of the to-be-monitored object in the monitoring scenario; conducting space partitioning on the display data in a display window so as to filter display data beyond the space of the display window, obtaining display window data within the space of the display window. According to the invention, the method and the system, by conducting space partitioning and optimization on the display data, can increase computing speed and reduce display time, and also addresses the problem of repetitive construction of the 3D display data.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to an imaging method and system for video surveillance. Background technique [0002] The virtual representation of the three-dimensional monitoring object is based on the key analysis of various performances or characteristics of the computer, and the obtained low-dimensional signal is processed and expressed as a graphic image with certain three-dimensional spatial position information, which is reconstructed by means of various depth restoration algorithms 3D spatial information. [0003] Traditional 3D modeling methods can be divided into two categories: [0004] The first category is to manually carry out three-dimensional geometric modeling through computer software, for example, by means of computer graphics software. [0005] The second type is to use the obtained low-dimensional signal, process it and express it as a graph or image with certain three-dimensiona...
