Problems solved by technology

However, if the control method based on the change of raindrop impact energy is bound to be affected by environmental factors such as rain force and wind force, it cannot truly and effectively reflect the amount of rainfall, so the corresponding control method does not match the actual working conditions.

Embodiment Construction

[0032] For raindrop recognition, it is necessary to establish a raindrop template library. The raindrop template can collect relevant samples, extract raindrops, store them, and add templates in the actual control of wipers. The templates can be shared in a larger monitoring system.

[0033] In this paper, it can be ideally represented as the raindrop template library has enough templates.

[0034] For monitoring equipment, such as the video captured by the camera, it is first digitized to facilitate subsequent processing. For example, the digitized image is very easy to convert into a bitmap or binarized to become a black and white picture.

[0035] Further, it can be changed to YUV data. YUV is a color coding method (belonging to PAL) adopted by the European television system, and is a color space adopted by PAL and SECAM analog color television systems. In modern color TV systems, three-tube color cameras or color CCD cameras are usually used to capture images, and then the...

Abstract

The invention discloses an automatic windshield wiper control method and aims to establish a rain drops template base. The automatic windshield wiper control method includes 1), digitalizing video images collected from video cameras; 2), detecting rain drops in the digitalized video images; 3), traversing the rain drops in the images according to given algorithm, matching types of rain drops in the rain drop template base, and calculating types of rain drops and corresponding numbers of the rain drops; 4), confirming rainfall according to calculated types of rain drops and the corresponding numbers of the rain drops; 5), confirming or adjusting the rotational speed of the windshield wiper according to the rainfall. The automatic windshield wiper control method is small in occupation source and high in efficiency and has good transportability.

Description

technical field [0001] The invention relates to a control method of an automatic wiper. Background technique [0002] With the rapid development of video surveillance technology, more and more video surveillance front-end equipment is installed in roads, squares, campuses, communities, banks, shopping malls and other public places. [0003] From the point of view of the installation site, the front-end equipment is divided into two types: outdoor type and indoor type. For outdoor equipment, since it needs to be waterproof and dustproof, it is necessary to install the camera for video collection, infrared lamps and laser lamps for supplementary lighting into protective covers such as glass, plastic, and metal. At the same time, a video window is opened on the protective cover so that the camera can collect images, transparent glass is installed on the video window, and a wiper is installed on the protective cover to clean the window glass. [0004] When it rains, the curren...
