Introduction
Close-range photogrammetry is a branch of photogrammetry that uses photography as a means to determine the shape, geometry, and other aspects of a target (other than terrain).
What position and motion status, etc.
Any target whose optical image can be taken can be used as the object of close-range photogrammetry. The target can be static or dynamic.
The images acquired can be analog or digital. Close-range photogrammetry can provide the plan, elevation, section, and panorama of the target object.
Maps, three-dimensional models, etc. can provide diversified results such as two-dimensional coordinates, three-dimensional coordinates of target points, and other parameters of engineering construction.
Close-range photogrammetry technology is widely used in various types of construction engineering, machinery manufacturing, aerospace technology, shipbuilding, automobile manufacturing, urban
Different fields such as regional planning, geology, mining, metallurgy, chemical engineering, medicine, biology, ancient architecture and ancient cultural relics research, and archaeology.
Close-range photogrammetry and conventional aerial photogrammetry have similarities in basic principles and the use of measuring instruments.
The quantitative work requires flexible selection of photography methods and determination of data processing methods based on the target object.
Specification for close range photogrammetry
1 Scope
This document specifies the accuracy, object space control, acquisition of close-range images, data processing and accuracy verification, and results data of close-range photogrammetry.
technical requirements.
This document is applicable to the application of close-range photogrammetry technology in building (structure) measurement, cultural heritage protection, industrial measurement, biomedicine, etc.
Application, other fields can refer to it.
2 Normative references
This document has no normative references.
3 Terms and definitions
The following terms and definitions apply to this document.
3.1
At two known control points or at both ends of a baseline of known length, the horizontal and vertical angles of the point to be determined are measured to determine the coordinates of the point to be determined.
Target method.
3.2
Standard length method
A method for determining the length of the baseline to be determined by measuring the known length of a standard placed in front of the baseline to be determined by measuring the angle forward intersection (3.1).
4.Accuracy
4.1 Accuracy Index
The accuracy of close-range photogrammetry should be expressed in terms of the relative mean error md/D (md represents the mean error of the photographic direction).
difference, D represents the photographic distance) or the relative mean error represented by the size of the target object ms/S (ms represents the mean error in measuring the length of the target object in a certain direction)
The error can also be expressed by the mean error of the measured point. The accuracy index is determined according to user needs.
4.2 Accuracy Estimation
Close-range photogrammetry should be estimated according to the photographic method, and the accuracy can be evaluated by redundant control points, redundant relative control, etc.
Estimate and keep records.
5.Object Control
5.1 Object Space Coordinate System
The object space coordinate system is a three-dimensional rectangular coordinate system. Generally, a free coordinate system is used. If necessary, it can be combined with other coordinate systems or.2000 national
