Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings of the description.

[0024] A method for checking the three-dimensional field of view of a mining dump truck, comprising the following steps:

[0025] (1) Before the visual field check, use the 3D drawing software to pre-establish the 3D model of the mining dump truck to be tested; the 3D drawing software can be AutoCAD, 3dmax, UG, SolidWorks, Pro / E, etc.;

[0026] (2) if figure 1 As shown in , the 3D model of a mine dump truck is imported into the 3D drawing software as the visual field analysis platform;

[0027] (3) Then transfer the 3D model of the sitting posture of the 50th percentile male to sit in the driver's driving position of a certain type of mining dump truck, which is equivalent to the state of the driver sitting in the driving position and driving;

[0028] (4) Then take the cut surface of the bottom of the tire as the reference plane, and regard it as ...

Abstract

The invention discloses a visual field checking method for a mining dump truck. The method comprises the following steps: importing a three-dimensional model of the mining dump truck into a visual field analysis platform; calling a driver at a driving position; making a reference surface on the three-dimensional model; dividing view areas according to standards; and finally, drawing lines in the three-dimensional model according to the visual field range seen by the eyes of the 50th-percent male sitting posture three-dimensional model, marking the visual field range, comparing the visual fieldrange with the boundary of the visual field, and checking whether the visual field requirement is met or not. Compared with a two-dimensional graph, the analysis of the oblique view of the view checkof the three-dimensional model is intuitive and clear, and whether the view meets the requirements or not can be easily judged; after the view check is completed, if the view does not meet the standard requirement, the three-dimensional model of the view check can be directly modified until the view requirement is met, and the step of three-dimensional export and two-dimensional repeated check inthe two-dimensional graph view check is omitted.

Description

technical field [0001] The invention relates to a mining dump truck, in particular to a method for checking the visual field of a mining dump truck. Background technique [0002] Existing mine dump truck field of view verification method: by exporting the 3D model into a 2D graph, and then performing field of view verification on the 2D graph, in the 2D graph, only the field of view from a single angle can be verified, and the verification Finally, give modification suggestions, and then make changes on the 3D model according to the modification suggestions. The disadvantages of this method are: it is difficult to check the oblique view in the two-dimensional graphic visual field, and it is difficult to check the left front and right front visual field, and after the correction is given on the two-dimensional graphic, it is still difficult to check. Changes need to be made on the 3D model, and after the 3D model is changed, the 2D map is repeatedly exported for field of vie...
