Embodiment Construction

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0023] The invention provides a marking device for extracting target features in intelligent video analysis of engineering drilling. The color of the marking main body is red and yellow, which are symmetrical up and down. Red and yellow show the strongest hue characteristics, which are the extremes of color contrast. From the visual point of view, they can be distinguished from the background color. The color characteristics of red and yellow reflected on the image are obvious, which is convenient for target feature extraction and tracking. ...

Abstract

The invention discloses a marking device for target feature extraction in engineering drilling intelligent video analysis. The marking device comprises a hollow cylinder, a silicone tube, two identical spacers and two identical buckles, the colors of the side face of the hollow cylinder comprise the red color and the yellow color, by taking the central cross section of the hollow cylinder as a boundary, a half of the side face of the hollow cylinder is red, the other half of the side face of the hollow cylinder is yellow, the spacers are mounted on the upper bottom face and the lower bottom face of the hollow cylinder correspondingly, the buckles are mounted on the outer sides of the spacers, and the silicone tube is inserted into a cavity of the hollow cylinder. The color of the marking device is determined on the basis of the color designing principle, the problem encountered in target feature extraction in current engineering investigation field operation intelligent video analysisis solved successfully, through the red-yellow bicolor design mode, the accuracy of target feature extraction is improved, and uniqueness is also achieved; and the marking device is simple in overallstructure, novel in design, high in practicability and reusable.

Description

technical field [0001] The invention relates to a marking device used for extracting target features in intelligent video analysis of engineering drilling, and belongs to the technical field of engineering geological drilling. Background technique [0002] At present, the competition in the survey industry is becoming more and more fierce, and the negative effects are prominent. The combined effect of various factors has led to the increasingly prominent problems of violations of specifications and technical requirements by engineering drilling and construction personnel during the construction of engineering survey sites, resulting in the lack of some engineering survey results. Accuracy, even the phenomenon that authenticity is difficult to guarantee. One of the keys to ensuring the quality of engineering surveys is high-quality field work. Only with real, complete and accurate first-hand information in the field can there be excellent survey results, otherwise the survey ...
