Method for collecting panoramic photographs assisting interpretation and checking of geographic national conditions

Abstract

The invention discloses a method for collecting panoramic photographs assisting interpretation and checking of geographic and national conditions. The method includes the following steps of: (1) data collection of the panoramic photographs; and (2) generation of the panoramic photographs. The generation of the panoramic photographs includes the steps of: (1) carrying out first treatment in treatment software of the panoramic photographs and obtaining apw engineering files; (2) generating template pano engineering files; (3) reading storage position information of each group of photographs from the apw engineering files generated from the first step by using the treatment software of the panoramic photographs, applying the matching rule pano engineering file of the template photograph to all the grouping photographs, outputting the pano engineering files of other panoramic photographs; and finally loading the multiple groups of pano engineering files generated by the treatment software of the panoramic photographs in Autopano Giga 3.6, and operating outputting of the multiple groups of the panoramic photographs; and (4) finding coordinate information recorded by GPS according to shooting times of the panoramic photographs, and outputting a tracing point layer. The method for collecting the panoramic photographs assisting interpretation and checking of the geographic national conditions has the advantages of low cost, high efficiency, high definition, high adaptability, high integration and high correctness.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping, and in particular relates to a panoramic photo collection method for assisting interpretation and verification of geographical conditions. Background technique [0002] The census of geographic national conditions is an important means to comprehensively obtain information on geographic national conditions, and it is the basic work to grasp the basic conditions of surface nature, ecology and human activities. The purpose of the census is to find out the current situation and spatial distribution of the country's natural and human geographical elements, lay the foundation for normalized geographic national conditions monitoring, meet the needs of economic and social development and the construction of ecological civilization, and improve the use of geographic national conditions information for the government, enterprises and the public. service capabilities. [0003] The main t...

Problems solved by technology

[0004] In the internal industry, the internal industry interpretation only uses the operators to distinguish the texture and color of the remote sensing image, and there is no actual land sample photo reference for interpretation and classification, resulting in a high error rate in the internal industry interpretation

Due to the quality and time phase of satellite remote sensing images, it usually increases the difficulty of internal interpretation and interpretation, especially in the case of complex land types, there are many cases of the same spectrum and foreign objects, which requires internal interpretation and field verification. Personnel repeatedly, carefully screened, investigated and verified, often can not fully distinguish clearly

Especially for areas with large undulating terrain and mixed vegetation, the number of spots generated during the interpretation process increases, which brings a huge workload to the internal interpretation work, making the production progress slow

[0005] In terms of field work, the workload of inspection, surveying and mapping is relatively large. The existing operation method of field operators is the whole field inspection, all of which rely on the operators to conduct on-site inspections. It is required to go to see. The strength is high, and the efficiency is not high. In addition, field operations are usually single-soldier operations. Due to the lack of quality and experience of the operators, it is particularly easy to cause misjudgments during the verification process.

In terms of the external environment, due to weather and terrain conditions that have a great impact on the field inspection work, for areas with cloudy, rainy and foggy weather, the working hours will be limited, and the effective time of the field inspection is short, which has brought a great deal of trouble to the actual production. difficulty

[0006] The existing mobile measurement technology can also realize the collection and production of panoramic photos for verification, and has high spatial precision and multiple data types, but the input cost is huge. The equipment cost of a vehicle-mounted mobile measurement system is as high as 5 or 6 million

In view of the mountainous and uneven roads that need to be visited in the geographical national conditions, and the large-scale measurement needs of the inspection task area, the existing mobile measurement equipment is really difficult to meet the production funds and time schedule requirements of the national census work. Therefore, research a low-cost, high-efficiency, high-adaptability mobile panorama that can embed the actual situation of the field into the production of the office, improve the quality and efficiency of the office, assist in the interpretation of images in the office, and check the field survey Acquisition equipment has become an urgent research topic
