Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] The present invention provides a technical solution: a method for detecting smoke in a diesel vehicle image, which is characterized in that it includes the following steps:

[0036] S1: Collect the exhaust smoke image of diesel vehicles, and use To represent a diesel vehicle tail gas emission image, where M and L are the number of rows and columns of matrix Y respectively;

[0037] S2: Obtain a smoke-free image from Y through image processing The specific method is:

[0038] There is the following relationship between Y ...

Abstract

The invention discloses a diesel vehicle image smoke intensity detection method, which comprises the following steps that a diesel vehicle tail tail gas emission smoke image is collected and is used for representing a diesel vehicle tail gas emission image, and M and L are the row number and the column number of a matrix Y respectively; and a smokeless image is obtained through image processing ofY, and the smoke intensity value is calculated according to the smoky image and the smokeless image. The invention also discloses a diesel vehicle image smoke intensity detection system, which comprises a memory, a processor and a computer program which is stored on the memory and can run on the processor, and is characterized in that the processor implements the diesel vehicle image smoke intensity detection method described in the claim 1 when executing the computer program. According to the method, the tail gas smoke plume image can be obtained by subtracting the smoky image from the smokeless image, and therefore, the vehicle emission smoke intensity value can be calculated according to the tail gas smoke plume image.

Description

technical field [0001] The invention relates to the field of vehicle exhaust detection, in particular to a diesel vehicle image smoke detection method and system. Background technique [0002] According to environmental protection requirements, it is necessary to detect whether the exhaust emissions of vehicles meet the standards. A common exhaust gas detection method is the remote sensing detection method. In the remote sensing detection method, a motor vehicle exhaust remote detector is required. Existing excited vehicle exhaust remote detectors such as Chinese patents CN105300914A discloses "a motor vehicle exhaust detection device", which includes a beam emitting and receiving device and a beam reflecting device. When the vehicle passes through the detection area, when the exhaust gas emitted by the motor vehicle cuts the detection beam, it will cause the spectral structure of the detection beam to change. Thus, the pollutant components and concentrations in the exhaust ...
