Problems solved by technology

[0004] Modeling based on images requires considerable professional knowledge and a large amount of calculation. It requires the use of professional computing software, which is difficult to achieve popularization. If ordinary people want to model indoors, they still need to seek help from relevant institutions or professionals, and the cost is relatively high.

Embodiment Construction

[0046] The technical solution of the present invention will be specifically described below in conjunction with the accompanying drawings and embodiments.

[0047] see figure 1 According to an embodiment of the present invention, a method for establishing a three-dimensional real scene of a house using public selfie panorama data includes the following steps:

[0048] Step 1. Collect the 360-degree panoramic data of houses uploaded by the public independently.

[0049] The present invention utilizes and uploads photos or videos about house panorama data taken and uploaded by the masses themselves. It is suggested that during the specific implementation, the provider of the photo and video should be reminded, and the corresponding actual requirements such as the texture information of the building object should be provided, so as to provide guarantee for the subsequent establishment of the 3D model.

[0050] During specific implementation, the user can use the panoramic camera ...

Abstract

The invention provides a method and system for establishing a house live-action three-dimensional model by using public selfie panoramic data. The method comprises the steps of: receiving house 360-degree panoramic data which are autonomously shot and uploaded by the public, and generating a house three-dimensional color point cloud by using the house 360-degree panoramic data; regularizing the house color point cloud, and selecting a wall surface; extracting a house plane graph based on the house point cloud; and displaying the 360-degree panorama, the plane graph and the three-dimensional model of the house in an associated manner. The method and the system enable the public to autonomously and quickly construct a live-action three-dimensional model of a house, and realizes low-cost, efficient and convenient three-dimensional visual digital expression of a house. By utilizing a 360-degree panoramic multi-view photogrammetry processing technology, the efficiency and accuracy of live-action three-dimensional model construction are remarkably improved, the cost of house live-action three-dimensional modeling and the workload of field data acquisition of professionals are reduced, crowdsourcing house three-dimensional modeling and visual expression are realized, and the method has a wide application prospect.

Description

technical field [0001] The invention belongs to the field of real-scene three-dimensional modeling, and in particular relates to a method and system for building a real-scene three-dimensional building based on public self-portrait panorama data. Background technique [0002] Indoor is an important place for human life, entertainment and study. How to quickly carry out 3D modeling of indoor scenes has become a hot issue in current research. So far, people are doing indoor scene modeling in various ways, and a lot of progress has been made. [0003] There are currently three methods for indoor scene modeling. One is to use CAD, 3ds max and other 3D software to build 3D models. Use some basic geometric elements to build a 3D model through a series of operations. This kind of geometric interactive modeling usually uses the data and height auxiliary data provided by indoor construction drawings, CAD, etc. to restore the indoor model. The method is low in cost, mature in tec...
