Step 3026, in response to that the shell image recognition result meets a preset abnormal condition, determining the shell image recognition result as an abnormal shell image recognition result.
In some embodiments, an executing entity (e.g., the computing device 101 shown in fig. 1) of the chassis housing detection method may determine the housing image recognition result as an abnormal housing image recognition result in response to the housing image recognition result satisfying a preset abnormal condition. Here, the preset abnormal condition may be: and the shell image recognition result is a preset result.

In some embodiments, the execution body may control the associated mobile inspection apparatus to perform surface defect inspection on each surface of the target enclosure to generate a surface defect inspection result, so as to obtain a surface defect inspection result set. Here, the associated movement detection device may be a mobile device communicatively connected to the execution main body for detecting whether a defect (such as corrosion, depression, breakage, or the like) exists on the surface of the chassis. For example, the movement detection apparatus may be a mobile robot on which the surface detector is mounted.

The related contents in steps 303-304 serve as an invention point of the present disclosure, thereby solving the technical problems mentioned in the background art, i.e., "the state of the computer case housing cannot be accurately detected due to a single detection method for the computer case housing, which is likely to cause abnormal outflow of the computer case housing". The factors that easily cause abnormal outflow of the computer case casing are as follows: the detection mode of the computer case shell is single, so that the state of the computer case shell cannot be accurately detected, and the abnormal computer case shell is easy to flow out. If the above factors are solved, the effect of reducing the outflow of the abnormal computer case shell can be achieved. To achieve this effect, first, the associated mobile inspection apparatus is controlled to perform surface defect inspection on each surface of the target enclosure to generate a surface defect inspection result, so as to obtain a surface defect inspection result set. Therefore, whether defects exist on each surface of the target chassis can be further detected. Next, it may be determined whether each surface defect detection result has a corresponding abnormal shell image recognition result. Therefore, whether the surface of the target chassis is abnormal or not can be judged through two detection results. Then, it is determined whether each surface defect detection result has a corresponding abnormal shell image recognition result. Therefore, whether the defect result detected by the model is consistent with the detection result of the surface defect detection result or not can be judged, and the state of the computer case shell can be accurately detected conveniently. And finally, in response to determining that the defect result represented by the surface defect detection result is consistent with the defect result represented by the abnormal shell image identification result, determining the surface defect detection result as an abnormal surface defect detection result. Therefore, the state of the computer case shell can be detected simultaneously in two modes, so that the accuracy of detecting the computer case shell is improved, and the outflow of abnormal computer case shells is reduced.
Optionally, in response to determining that the defect result represented by the surface defect detection result is inconsistent with the defect result represented by the abnormal shell image recognition result, determining the pre-trained shell image recognition model as the shell image recognition model to be trained.
In some embodiments, the performing body may determine the pre-trained shell image recognition model as the shell image recognition model to be trained in response to determining that the defect result represented by the surface defect detection result is inconsistent with the defect result represented by the abnormal shell image recognition result.
Optionally, a training sample set of the chassis enclosure is obtained.
In some embodiments, the execution subject may obtain a training sample set of the chassis housing from the terminal device through a wired connection or a wireless connection. The training samples in the training sample set comprise sample shell images and labels corresponding to the sample shell images. Here, the sample housing image may include, but is not limited to: damaged hull image, rusted hull image, depressed hull image. Here, the label corresponding to the sample housing image may include, but is not limited to: a label corresponding to an image of a damaged housing, a label corresponding to an image of a rusted housing, and a label corresponding to an image of a sunken housing. Here, the label corresponding to the broken case image may be a character indicating that the case is broken. Here, the label corresponding to the rusted case image may be a character indicating the case rust. Here, the label corresponding to the depressed housing image may be a character indicating the depression of the housing.
Optionally, the shell image recognition model to be trained is trained according to the training sample set, and the shell image recognition model after training is obtained and used as a new shell image recognition model.
In some embodiments, according to the training sample set, the executing entity may train the shell image recognition model to be trained through the following steps to obtain a trained shell image recognition model as a new shell image recognition model:
firstly, determining a network structure of the shell image recognition model to be trained. For example, it needs to determine which layers the shell image recognition model to be trained includes, the connection order relationship between layers, and which neurons each layer includes, the weight (weight) and bias term (bias) corresponding to each neuron, the activation function of each layer, and so on.
And secondly, taking each sample shell image included in the training sample set as the input of the shell image recognition model to be trained, taking each label corresponding to the sample shell image included in the training sample set as the expected output of the shell image recognition model to be trained, and training the shell image recognition model to be trained by utilizing a deep learning method.
