Embodiment 1

[0046] Embodiment 1, a target detection method for automatically switching scene modes, referring to the attached figure 1 .

[0047] A target detection method for automatically switching scene modes of the present invention, comprising the following steps:

[0048] Step 1: Judging the background model of target detection according to the humidity and average brightness of the current frame; the specific judgment method is: use the humidity sensor to obtain the current humidity Ht, convert the current frame to HSV space, extract the V space component, and calculate the average of the current frame Brightness Vt, if consecutive t1 frames Ht>Hhigh, Vt>Vhigh, and the background model that rains during the day is not currently used for target detection, initialize the background model that rains during the day for target detection; if consecutive t1 frames HtVhigh, and the background model that is not raining during the day is currently not used for target detection, initialize th...

Embodiment 2

[0076] Embodiment 2, a target detection device for automatically switching scene modes, refer to the attached figure 2 .

[0077] A target detection device for automatically switching scene modes, including a humidity sensor unit 1 for collecting humidity information in the current environment, an image acquisition unit 2 for collecting monitoring images, and for switching between background models and background modeling The background modeling unit 3, the moving object detection unit 4 for obtaining the current frame moving object and the background model update unit 5 for controlling the update of different background models; the humidity sensor unit 1 is arranged in the scene to be tested, so The humidity sensor unit 1 and the image acquisition unit 2 are connected to the background modeling unit 3 and send the collected information to it, the background modeling unit 3 is connected to the moving object detection unit 4, and the moving object The object detection unit 4 ...

Abstract

The invention provides a target detection method capable of switching the scene mode automatically. The method comprises the following steps that a background model of target detection is determined according to the humidity of a current frame and the average brightness; the difference between the current frame and the background model is solved to obtain a moving target; and the background model is updated according to the moving target. The outdoor scenes comprise a daytime no-rain scene, a daytime rain scene, a night no-rain scene and a night rain scene, different background models are established for the different scenes, when a mode switching condition is satisfied, the model is automatically switched and initialization is carried out automatically, and thus, the problem that the mode is incapable of adapting to complex backgrounds is effectively solved.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to an object detection method and device for automatically switching scene modes. Background technique [0002] Distinguishing the moving target from the sequence image and the image background is the basic task of target detection. The main goal is to extract the moving information of the target to simplify the subsequent image analysis, feature extraction, recognition and other work. Target detection is a key technology in the field of intelligent video surveillance, and it is also a difficult point. The quality of target detection results has an important impact on subsequent analysis. However, there are often various interference factors in the actual detection scene, such as: the wind and grass of the leaves, the gradient and sudden change of the light, the influence of rain and snow, etc., making it a current task to quickly and accurately detect the foreground from the complex ...
