specific Embodiment approach 1

[0040] Specific implementation mode one: the following combination Figure 1 to Figure 3 Describe this embodiment, this embodiment is a kind of fault detection method based on image processing fire protection panel of railway freight car, specifically includes:

[0041] Step 1. Establish a set of normal subgraphs of fireproof boards, a collection of lost subgraphs of fireproof boards and a collection of damaged subgraphs of fireproof boards;

[0042] Step 2, using the normal subgraph set of the fireproof board and the lost subgraph set of the fireproof board to establish a judgment model for missing faults;

[0043] Using the set of normal subgraphs of the fireproof board and the set of damaged subgraphs of the fireproof board, the judgment model of damage fault is established;

[0044] Calculate the gray level co-occurrence matrix of each normal submap and each lost submap, and determine the judgment interval of the missing fault;

[0045] Calculate the gray level co-occurr...

Abstract

The invention discloses a railway wagon fireproof plate fault detection method based on image processing, and belongs to the field of fault detection based on image processing. The problems that due to the fact that manual processing is adopted in existing troubleshooting and detection of the truck fireproof plate, missed detection or simplified operation is prone to occurring, and troubleshooting of fault causes is not facilitated are solved. The method comprises the following steps: constructing a judgment model of a loss fault and a judgment model of a damage fault, and determining a judgment interval of the loss fault and a judgment interval of the damage fault by using a gray-level co-occurrence matrix; intercepting a fireproof plate area of a to-be-detected image, judging by adopting the judgment model of the loss fault, judging loss again by adopting the judgment interval of the loss fault if no loss exists, judging damage by adopting the judgment model of the damage fault if no loss exists, judging damage again by adopting the judgment area of the damage fault if no damage exists, and judging that the fireproof plate is intact if no damage exists; and if any judgment result is loss or damage, stopping judgment, and completing one detection. The invention is suitable for truck fireproof plate fault detection.

Description

technical field [0001] The invention belongs to the field of fault detection based on image processing. Background technique [0002] For the fault detection of the fire protection panel of the truck, at this stage, manual troubleshooting is generally used for troubleshooting. Since the inspection operation is greatly affected by factors such as the professional quality, sense of responsibility, and labor intensity of the operator, it is easy to miss inspection or simplify the operation. Moreover, the efficiency of manual inspection is low. Once a quality problem occurs, it is not conducive to finding the cause of the problem and the time when the problem occurred during the operation. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the inspection and detection of the fire protection board of the existing freight car adopts manual processing, which is prone to missed inspection or simplified operation, which is not cond...
