Embodiment 1

[0056] Such as figure 1 As shown, the present invention discloses a method for information statistics based on target recognition, which includes the following steps:

[0057] Step 1: Set up a number of camera units for continuous shooting of the scene, and there is an overlapping field of view between every two cameras;

[0058] Step 2: Obtain the latest frame from the video stream of each camera unit at a fixed frequency, assign a timestamp, and store the acquired frame in the corresponding queue of the respective video stream, and each queue has a timeout, and the frames in the queue are in It will be discarded after timeout;

[0059] Step 3: Continuously obtain frames from the current time t (1s≤t≤2s) from each queue, and perform target detection. If there is a detection target in the frame, send the frame to step 4; if there is no detection in the frame target, then send the frame to step 5 and step 6;

[0060] Step 4: For the frame containing the detected target, perf...

Abstract

The invention relates to the field of computers, discloses an information statistics method based on target identification. Processing is carried out through logic optimization, the motion track of each tracking target can be recorded in detail; the method comprises the following steps: obtaining a plane structure, colors and the like of a plurality of cameras, realizing target tracking with certain reliability through global modeling of view fields of the plurality of cameras in combination with a target detection technology, and if a tracking target is lost or causes error tracking due to partial or complete shielding, correcting and recovering tracking through target information; and if the target information cannot be obtained temporarily, tracking can be carried out by analyzing the target motion track and the color characteristics.

Description

technical field [0001] The invention relates to the computer field, in particular to an information statistics method based on target recognition. Background technique [0002] Monitoring is the physical basis for real-time monitoring of key departments or important places in various industries. Management departments can obtain effective data, image and video monitoring system schematic diagrams or sound information through it, and monitor and remember the process of sudden abnormal events in time. It is used to provide efficient and timely command and height, deploy police force, handle cases, etc. With the rapid development and promotion of current computer applications, a powerful wave of digitization has set off all over the world, and the digitization of various devices has become the primary goal of security protection. The performance characteristics of digital monitoring and alarm are: real-time display of monitoring screen, single-channel adjustment function of vi...
