Vehicle tail gas puff positioning detection method, device, and equipment, storage medium and system

Abstract

The invention is applicable to the technical field of computers, and particularly relates to a vehicle tail gas puff positioning detection method, device and equipment, a storage medium and a system. The method comprises the following steps: obtaining multiple frames of reflective band spectral images, collected under a periodically-changed infrared band, of a vehicle when the vehicle passes through a reflective band and splicing according to the time sequence; determining a reflective tape CO2 absorbance image and a reference matrix under different infrared bands, and correcting the reflective tape CO2 absorbance image by using the reference matrix; and determining the position information of the vehicle tail gas puff, and further detecting the vehicle tail gas puff according to the position information. According to the vehicle tail gas puff positioning detection method, the CO2 waveband spectrum diagram is used for positioning the position of the tail gas puff, the reference waveband spectrum is used for eliminating the influence of factors such as light intensity, and the defect that an existing vertical tail gas tele-metering device cannot position the vehicle tail gas puff can be well overcome; tail gas detection of a vehicle with an exhaust pipe not located at the tail of the vehicle can be achieved.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a vehicle exhaust puff location detection method, device, equipment, storage medium and system. Background technique [0002] The analysis of the components in the vehicle exhaust puff can effectively prevent the emission of highly polluting exhaust and protect the environment. In the prior art, most of the analysis of the components in the vehicle exhaust puff is based on the vertical exhaust telemetry equipment. Specifically, when the front of the vehicle reaches the reflection zone, the reflected signal of the test host is blocked, while in the vehicle The moment the tail leaves the reflection band, the test host can receive the reflected spectrum signal again, so that it can immediately start to collect the spectrum continuously, and analyze and calculate the CO in the tail gas. 2 , CO, C 3 h 8 , the concentration of NO and other gases with different componen...
