Field geographic information surveying and mapping equipment and measuring method thereof

Abstract

The invention discloses field geographic information surveying and mapping equipment. The equipment comprises a supporting platform, a main shaft and a surveying and mapping instrument adjusting mechanism; the main shaft is hinged to the bottom of the supporting platform; the surveying and mapping instrument adjusting mechanism is fixedly arranged at the top of the supporting platform; the surveying and mapping instrument adjusting mechanism comprises a fixed shaft, a height adjusting mechanism, a direction adjusting mechanism and a pitching adjusting mechanism; the height adjusting mechanismis used for adjusting the height of a surveying and mapping instrument; the direction adjusting mechanism is used for adjusting the surveying and mapping direction of the surveying and mapping instrument; the pitching adjusting mechanism is used for adjusting the surveying and mapping angle of the surveying and mapping instrument; the fixed shaft is fixedly arranged on the direction adjusting mechanism; the height adjusting mechanism is arranged on the direction adjusting mechanism; the pitching adjusting mechanism is arranged on the height adjusting mechanism; and the surveying and mapping instrument is arranged on the pitching adjusting mechanism. The equipment has the beneficial effects that the supporting platform can be rapidly and efficiently leveled, the surveying and mapping direction of the surveying and mapping instrument can be adjusted at will, the height of the surveying and mapping instrument can be adjusted conveniently, the pitching angle of the surveying and mapping instrument can be adjusted and the equipment can adapt to uneven ground.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping equipment, in particular to a field geographic information surveying and mapping equipment and a measuring method thereof. Background technique [0002] Surveying and mapping equipment refers to instruments and devices such as data acquisition, processing, and output designed and manufactured for surveying and mapping operations, and various orientation, distance measurement, angle measurement, Instruments for height measurement, mapping and photogrammetry. The current surveying and mapping equipment includes a supporting platform, a surveying and mapping instrument and a surveying and mapping bracket. The bottom of the supporting platform is hinged with three surveying and mapping supports in its circumferential direction. The surveying and mapping instrument is fixedly installed on the top of the supporting platform. For geographic information, the operator can deploy and support ...

Problems solved by technology

[0003] When using the surveying and mapping equipment to survey and map the geographical information of the field, the operator supports the three surveying and mapping supports on the field, and then adjusts the position of each surveying and mapping support relative to the supporting platform to ensure that the supporting platform is in a flat state, that is, to ensure that the supporting platform is The platform is parallel to the ground surface. If the supporting platform is not flat, the lens of the surveying and mapping instrument will be tilted, thereby reducing the measurement accuracy of the surveying and mapping instrument. When the supporting platform is adjusted in place, the field can be surveyed and mapped by the surveying and mapping instrument

However, although this kind of surveying and mapping equipment can complete the surveying and mapping of the geographical information of the field, the ground in the field is uneven, so that it takes a long time for the operator to adjust the support platform to a horizontal state, which not only increases the labor intensity of the workers , but also reduces the adjustment efficiency

In addition, the existing surveying and mapping equipment also has the following defects: 1. The surveying and mapping angle of the surveying and mapping instrument lens cannot be adjusted at all, and the entire surveying and mapping equipment needs to be moved multiple times to complete the surveying and mapping of the geographic information of the entire field

2. When it is necessary to adjust the height of the surveying and mapping instrument, it is necessary to move closer to or unfold three surveying and mapping supports to complete the adjustment of the height of the surveying and mapping instrument, which is very inconvenient

3. Since the surveying and mapping instrument is fixed on the support platform, the pitch angle of the surveying and mapping instrument cannot be adjusted, so the geographical information of the high and low areas cannot be surveyed and mapped
