Embodiment Construction

[0028] In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0029] In the construction industry, people often make requirements on the color of architectural surfaces with decorative surfaces (eg doors, windows, walls). For example, it is required that the color difference of each area of ​​the building surface formed by the exposed concrete external wall panels cannot be too large.

[0030] However, at present, the color difference de...

Abstract

The invention is applicable to the technical field of image processing, and provides a color difference detection method and device based on a point cloud technology, a terminal and a medium. The color difference detection method comprises the following steps: acquiring first point cloud data of a building surface; restoring a first point cloud image of the building surface according to the firstpoint cloud data; and acquiring a preset standard color block, and performing color difference detection on the first point cloud image by using the standard color block to obtain a first color difference detection result. According to the embodiment of the invention, the efficiency, reliability and traceability of color difference detection are improved.

Description

technical field [0001] The present application belongs to the technical field of image processing, and in particular relates to a color difference detection method, device, terminal and medium based on point cloud technology. Background technique [0002] In the construction industry, people often make requirements on the color of the building surface with decorative surface. For example, it is required that the color difference of each area of ​​the building surface formed by the exposed concrete external wall panels cannot be too large. [0003] However, at present, the color difference detection of building surfaces can only be identified and inspected by naked eyes. Due to the influence of individual subjectivity, the detection efficiency is low, the reliability is poor, and it is not easy to be traced. A reliable method for the detection of color difference of building surfaces is needed. Contents of the invention [0004] Embodiments of the present application provi...
