Abstract

The invention provides a high-recognition-performance laser processing machine tool. The high-recognition-performance laser processing machine tool comprises a laser processing machine tool body and a target recognition device connected with the laser processing machine tool body. The target recognition device recognizes and traces a target on the basis of visual features, and comprises a suspected target obtaining module, a color information processing module, a contour information processing module and a feature evaluation module, wherein the suspected target obtaining module, the color information processing module, the contour information processing module and the feature evaluation module are sequentially connected, and the color information processing module conducts conversion from the RGB color space to the HSV color space on an original frame image and establishes a hue and color model of a suspected target in the HSV color space. The contour information processing module is used for conducting area type division of feature areas and non-feature areas of the actual contour of the original frame image, combines the adjacent areas of the same types, and selects filters of different parameters to conduct smoothing processing on the combined feature areas and the combined non-feature areas. The high-recognition-performance laser processing machine tool has the beneficial effects of being high in recognition precision and high in recognition speed.

Description

technical field [0001] The invention relates to the field of laser processing, in particular to a laser processing machine tool with high recognition performance. Background technique [0002] In related technologies, using radar to track targets on laser processing machine tools has great advantages in positioning accuracy and tracking success rate, but it is difficult to distinguish the characteristics of targets only from the distance information obtained by radar, especially when the target is In the case of occlusion and multiple targets, it is difficult to achieve effective target recognition and tracking. It is an effective way to solve the above problems by using the visual information of the target (such as color, outline, etc.) to describe the target features, and to identify and track the target based on the target visual features. Contents of the invention [0003] In view of the above problems, the present invention provides a laser processing machine tool wi...
