Embodiment Construction

[0037] The present invention is described in detail below in conjunction with accompanying drawing:

[0038] Such as figure 1As shown, the present invention provides a light and small three-dimensional laser scanning measurement system, comprising a GPS positioning system, an inertial navigation system INS, a laser scanner, a digital camera, a serial port and a data acquisition computer; Antenna and GPS receiver; the GPS receiver, the inertial navigation system INS and the laser scanner are all connected to the data acquisition computer through the serial port. The GPS positioning system, INS and laser scanner are controlled by the data acquisition computer to collect, transmit and save the data. In addition, the GPS positioning system, inertial navigation system INS, and laser scanner all use light, small and low-cost hardware systems. The GPS antenna may be a GPS aerial antenna for receiving GPS signals. The data acquisition computer adopts a flat-panel touch-type industr...

Abstract

The invention provides a light and small three-dimensional laser scanning measurement system and method. The light and small three-dimensional laser scanning measurement system comprises a GPS (Global Position System), an inertial navigation system INS, a laser scanner, a digital camera, a serial port and a data acquisition computer, wherein the GPS positioning system comprises a GPS antenna and a GPS receiver, which are electrically connected with each other; the GPS receiver, the inertial navigation system INS and the laser scanner are connected to the data acquisition computer through the serial port; and the GPS receiver is further respectively connected with the digital camera and the INS. The invention has the advantages of low cost and good portability, and is particularly suitable for data acquisition in small regions, such as small districts, factories, villages and towns within an area of 50 square kilometers.

Description

technical field [0001] The invention belongs to the technical field of geographic information data collection, and in particular relates to a light and small three-dimensional laser scanning measurement system and method. Background technique [0002] At present, geographic information data collection has shifted from traditional two-dimensional data collection to three-dimensional space data collection, and with the rapid development of related data collection technologies and means, people have higher and higher requirements for three-dimensional spatial information services, namely It is required to have three-dimensional spatial information at different scales and at different times, and it is also required to achieve certain effects in terms of accuracy and fidelity. 3D laser scanning technology is the latest developed geographic information data acquisition technology, which can directly acquire a large amount of real 3D data of the target, and the collected point clou...
