Abstract

The embodiment of the invention discloses a rendering method and device for an automobile model image, vehicle-mounted image equipment and an automobile. The method comprises the steps that an illumination model is utilized to determine a primary rendering image of the automobile model image; according to highlight brightness of each pixel point in the primary rendering image, a highlight brightness value of each pixel point is determined; and the highlight brightness values, smaller than a set partitioning threshold value, of the pixel points in the primary rendering image are regulated according to a dynamic regulation ratio, and the region where the pixel points are located after regulation is determined as a glow region. By the adoption of the technical scheme in the embodiment, the effects of improving the authenticity of the automobile model image of a vehicle-mounted image system, increasing the computing rate and lowering a hardware configuration demand can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automotive electronics, and in particular to a rendering method and device for an image of an automobile model, an on-vehicle imaging device, and an automobile. Background technique [0002] With the continuous improvement of people's living standards, the current vehicle imaging system has become an indispensable part of the automotive industry. [0003] In the traditional photorealistic lighting rendering model, the most representative rendering algorithms are the Phong lighting model and the improved Blinn-Phong lighting model. These two models divide the lighting effects of the object surface into ambient light, scattered light, and reflection. There are four components of light and self-illumination. Different lighting effects can be achieved through different combinations of components. These two models have the advantages of good versatility and simple calculation. They are th...
