Title:
INTELLIGENT VISUAL SAMPLING METHOD, SYSTEM AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/220522
Kind Code:
A1
Abstract:
The invention relates to the field of measurement, and in particular to an intelligent visual sampling method, system and device. A reference coordinate system is established through the initial position of a camera. The camera is located at the sampling position to shoot and obtain a shot image. A sampling point is selected in the shot image. A deviation angle and a distance of the position of a laser spot when the sampling point is located at the initial position of the camera are used as coordinate values under the reference coordinate system. All sampling points are subjected to information sampling. Finally, a spatial three-dimensional model containing all the sampling point information is output. The spatial three-dimensional model is used to quickly obtain survey data, and achieve accurate and efficient engineering acceptance work.
