Method for registering types of raise dust of fixed source

Abstract

The invention discloses a method for registering types of raise dust of a fixed source. The method relates to fixed source raise dust type registration, comprises a Harris corner point algorithm and an image registration process, and further comprises the following steps: setting sampling points according to the fixed source raise dust type, selecting one optimal image in each sampling interval toform a registration image set, and taking other images as source images for testing; performing the same preprocessing on the source image and the registration image; setting a registration area; calculating a correlation coefficient of a registration area of the source image and the registration image; utilizing the correlation coefficient to judge the matching degree of the source image and theregistration image; and entering an image registration process. According to the method, the types of raise dust of a fixed source can be effectively distinguished, and an ideal registration image set is obtained; and the method has good characteristic invariance, uniqueness, stability and independence, and can realize identification of different fixed dust sources such as excavation, decorationand total balance.

Description

technical field [0001] The invention relates to the category registration of fixed source dust, in particular to a method for registration of fixed source dust categories. Background technique [0002] During the conveying and processing of powders and granules, the induced air flow, the flowing air caused by indoor ventilation and the airflow generated by the rotation of equipment moving parts will firstly separate the fine dust in the granules from the granules and fly away, and then due to The flow of indoor air causes the diffusion of dust, thus completing the process from dust generation to diffusion. This phenomenon is particularly evident on construction sites. Image registration is the process of superimposing two or more images of the same scene obtained by different time, different viewing angles, and different sensors. At present, it is difficult to distinguish the types of fixed source dust, and it is difficult to identify different fixed dust sources such as e...
