Problems solved by technology

Traditional 3D reconstruction methods, such as binocular vision methods, are difficult to determine feature points and perform effective matching due to the simple background and structure relationship of microphotographs, low contrast, optical distortion, etc. , Calibration difficulties and other reasons are difficult to popularize. In addition, there are few reports on the 3D reconstruction of the tool wear area at home and abroad.

Embodiment Construction

[0032] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0033] Such as figure 1 As shown, the present invention designs a kind of tool wear three-dimensional appearance detection method, comprises the following steps:

[0034] Step 001. Place the tool under the image capture device, the image capture direction of the image capture device points to the tool wear area, and adjust the vertical height of the image capture device so that the focus area of ​​the image capture device is located at the bottom of the tool wear area, Obtaining the image captured at this time by an image capture device;

[0035] Step 002. Move the image capture device vertically upwards by a preset distance Δh in sequence until the focus area of ​​the image capture device is located at the top of the tool wear area, and obtain the image captured after each time the image capture device moves vertically...

Abstract

The invention relates to a three-dimensional shape detection method for tool wear. Hierarchical focusing image capturing is carried out on each part of a tool wear area, the clearest pixel point of the tool wear area is judged and obtained on the basis, finally a three-dimensional model of the tool wear area is built through a three-dimensional modeling mode, and therefore detection of the tool wear area is achieved, the shortcomings of detection of the tool wear area in the prior art are overcome, the hierarchical scanning and photographing technology and the three-dimensional modeling technology are effectively combined to be applied to detection of the tool wear area, and fast and accurate detection of the tool wear area is achieved.

Description

technical field [0001] The invention relates to a three-dimensional shape detection method for tool wear. Background technique [0002] Tool wear has an important influence on the quality of workpiece surface machining. In recent years, domestic researchers have conducted a lot of research on tool wear state detection technology, and these studies mainly tend to the following three aspects: (1) to measure the chips generated by the tool during the cutting process, this method is an indirect measurement method , is still in the stage of theoretical research; (2) monitoring specific machine tool parameters to judge the wear of the tool is also an indirect measurement method, although the operation is relatively easy, but the accuracy is not high; (3) directly observe the tool, Although this method has high precision, it is difficult to implement. [0003] The wear area of ​​the tool is concentrated in the micron-level research range, which puts forward higher requirements fo...
