Three-dimensional-point-cloud-scanning-technology-based digitized information collection method of linxia-county brick carving

Abstract

The invention discloses a three-dimensional-point-cloud-scanning-technology-based digitized information collection method of linxia-county brick carving. The method comprises: step one, an oblique photographing device collects three-dimensional point cloud data of a building roof and a surrounding environment of a building with brick carving; step two, a fixed standing type three-dimensional laserscanning device collects three-dimensional point cloud data of a wall body of the building with the brick carving; step three, a handheld three-dimensional laser scanning device is used for collecting three-dimensional point cloud data of the brick carving precisely; and step four, the data collected by the three steps step are processed to obtain a three-dimensional digital model conforming to the real situation completely. Therefore, problems of too long brick carving protection time, large task load, and large error because of being lack of scientific, strict, and accurate recording of thetraditional surveying and mapping method in the prior art can be solved; and a problem of pattern deformation in the traditional brick carving mapping is also solved.

Description

technical field [0001] The invention belongs to the technical field of architectural surveying and mapping, and in particular relates to a method for collecting digitized information of Linxia brick carvings based on three-dimensional point cloud scanning technology. Background technique [0002] Brick carving refers to the carving of figures, landscapes, flowers and other patterns on blue bricks. It is an important art form in ancient architectural carvings in the East and the West. The development of brick carving in our country has a long history, and it has a history of at least two thousand years. [0003] In our country, the sculpture technology with bricks as the carrier appeared in the Eastern Zhou Dynasty, but until the portrait bricks in the Han Dynasty, the decorations on the bricks were all carved on the mud or pressed with a mold, which cannot be called sculpture. Works, while the real brick carvings appeared around the Jin, Southern and Northern Dynasties. At...
