Embodiment Construction
[0011] The solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0012] Such as figure 1 As shown, the pointer instrument recognition method based on the inspection robot includes the following steps:
[0013] Step 1. Classifier training: Use the instrument image dataset to train the Adaboost classifier, and select an image centered on the instrument as a template image for each inspection point. Since the instrument image dataset contains instrument images under different lighting and attitude conditions, the instrument can be accurately extracted no matter how the instrument detection environment changes.
[0014] Step 2. Instrument area positioning: Obtain the image of the instrument to be inspected at the specified inspection point, combine the Adaboost classifier and the template image for rough positioning and precise positioning, and filter out the dial area. The specific method is: ...
