Embodiment Construction

[0044] In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0045] An embodiment of the present application provides a method for determining the visibility of a rear muffler of a vehicle, which can be applied to a terminal. Optionally, the terminal may be a mobile phone, a tablet, a notebook computer or a desktop computer. see figure 1 , the method includes:

[0046] Step 101 , obtaining the target contour line of the rear bumper of the vehicle from the three-dimensional model of the vehicle.

[0047] Wherein, the target contour line of the rear bumper in the three-dimensional model of the vehicle is the contour line on the side close to the reference plane among the contour lines of the rear bumper. The reference plane is the bearing surface of the wheel in the three-dimensional model in the ...

Abstract

The invention discloses a visibility determination method and device for a rear silencer of a vehicle, and relates to the technical field of vehicles. The terminal can establish a view surface based on the extracted target contour line of the rear bumper of the vehicle and the observation reference point, and sends a reminding message after determining that the rear silencer in the three-dimensional model of the vehicle intersects with the view surface, so as to indicate that the rear silencer does not meet the visibility design requirement. The target contour line is extracted from the three-dimensional model of the vehicle, namely, the visibility of the rear silencer of the vehicle can be determined in the design stage of the vehicle, and the visibility of the rear silencer does not need to be determined after a sample vehicle is manufactured, so that the visibility determination efficiency of the rear silencer of the vehicle is effectively improved, and the visibility determination efficiency of the rear silencer of the vehicle is improved. And the visibility determination cost of the rear silencer can be reduced.

Description

technical field [0001] The present application relates to the technical field of vehicles, and in particular, to a method and device for determining the visibility of a rear muffler of a vehicle. Background technique [0002] The vehicle may include a rear muffler capable of reducing noise generated when the vehicle's engine is operating. Also, for safety and aesthetic considerations, the rear muffler of the vehicle needs to meet the design requirements for visibility. The visibility design requirement means that when the distance between the person and the rear of the vehicle is less than or equal to the target distance, the rear muffler is out of the field of vision of the human eye. [0003] In the related art, a sample vehicle (ie, a prototype vehicle) may be first manufactured based on the design drawing of the vehicle. Then, the staff can observe whether the rear muffler of the prototype can be seen at the target distance from the prototype. After seeing the rear mu...
