Problems solved by technology
[0003] The method of using the principle of laser ranging in the current surveying and mapping instruments will be disturbed by the change of air refractive index, and dust and other particles are easy to be generated in the construction environment, which will work together with the change of environmental temperature and humidity, reducing the data accuracy of the surveying and mapping instruments , thus weakening the accuracy of municipal engineering surveying and mapping results, affecting the effect of municipal facilities construction according to plan
[0004] There are also some technical solutions on municipal engineering surveying and mapping methods in the prior art. For example, a Chinese patent with application number 2016109075996 discloses a municipal engineering-based surveying and mapping method to solve the problem of low accuracy of geological space measurement schemes in traditional geological surveying and mapping. , the defect of large workload in the later stage, especially the problem of difficult surveying and mapping under the complex geological environment, the surveying and mapping method based on municipal engineering includes the following steps: determining the datum level and datum point; drawing the distribution map of underground pipelines; ground static laser surveying and mapping ;Dynamic laser surveying and mapping on the ground; drawing the surveying and mapping model map of the surveying and mapping area; Reduce the error, simple operation and high efficiency; however, this technical solution does not solve the problem that the accuracy of the surveying and mapping data is weakened by the influence of the refractive index of the air in the use of surveying and mapping instruments, thereby reducing the construction accuracy of municipal engineering

Embodiment Construction
[0029] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0030] Such as Figure 1 to Figure 6 Shown, a kind of municipal engineering surveying and mapping method described in the present invention, the method steps are as follows:
[0031] S1. Positioning benchmarks; select at least two completed municipal facilities near the municipal engineering as reference points, and two ends of the current municipal engineering area as positioning points, respectively measure the position data between the positioning points and the reference points, and calculate their positions The difference between the data and the theoretical data of the design plan is recorded as A data; by using the completed municipal facilities as the reference point, the preliminary calibration steps required in the selection of positioni...

The present invention relates to the technical field of surveying and mapping, in particular to a municipal engineering surveying and mapping method and a supervision system, including a surveying and mapping method of positioning reference, secondary surveying and mapping, error measurement and data calibration, wherein the calibration rod used includes a rod body, a bare plate and an end block; The method of using the principle of laser ranging in surveying and mapping instruments will be interfered by changes in the refractive index of the air, which reduces the data accuracy of the surveying and mapping instruments, thereby weakening the accuracy of municipal engineering surveying and mapping results, and affecting the construction of municipal facilities according to the plan; therefore, The present invention compares its actual length with the measured data through the calibration rod arranged on the surveying and mapping instrument, and forms a group of related data sets with the data in municipal engineering surveying and mapping respectively, and uses the data fitting Correlation function curves, and then estimate the interference of air refractive index on surveying and mapping values, and calculate higher-precision surveying and mapping data, thereby improving the data accuracy of municipal engineering surveying and mapping methods.
Description
technical field [0001] The invention relates to the technical field of surveying and mapping, in particular to a municipal engineering surveying and mapping method and a supervision system. Background technique [0002] Municipal engineering generally belongs to the country's infrastructure construction, which refers to the construction of various public infrastructure in urban construction. The surveying and mapping effect is related to the construction quality of municipal facilities, so that urban construction can be implemented steadily according to the plan, and the supervision controls the surveying and mapping production. The quality of each process in the process, so as to ensure the quality of the final surveying and mapping results; for the introduction of municipal engineering surveying and mapping and supervision, please refer to: Yang Shaoyu, Talking about the content and methods of surveying and mapping engineering supervision [J], Surveying and Mapping and Spat...
