Field photogrammetry hand-held machine

Abstract

The invention discloses a field photogrammetry hand-held machine. The field photogrammetry hand-held machine comprises a circuit board arranged in a casing, circuit board plug members arranged in the casing and an image acquisition system arranged outside the casing; the circuit board is formed through welding unit modules comprising a high-speed processing unit, and a three-dimensional gesture sensing module, a display module, a GPS module, a GPS antenna, a communication module, an image reception module, a power supply management module and a multipath interface which are connected with the high-speed processing unit; the power supply management module is connected with the power supply input ends of the above other modules; the circuit board plug members are plugged into the circuit board; and the image acquisition system comprises a multipath arranged on the image reception module, and an optical lens and an infrared / low-light night vision device which are connected with the multipath interface. The field photogrammetry hand-held machine has the advantages of realization of field work, convenient carrying and operation, high efficiency, multiple functions, high precision, high reliability, and low cost.

Description

technical field [0001] The invention relates to a field photogrammetry handheld device, which is mainly used for close-range photogrammetry field equipment with functions such as global positioning, three-dimensional attitude measurement, photogrammetry, broadband wireless communication, etc., and completes real-time data collection and real-time data transmission of field close-range photogrammetry . Background technique [0002] At present, there are only equipment integration systems for road photogrammetry data acquisition on the market. Abroad, the United States, Canada, Nordic countries, Australia, and Japan all have road photogrammetry data acquisition systems based on equipment integration technology; in China, there is a "3S integration technology-based LD2000 series mobile road measurement system (road photogrammetry data acquisition system). Road photogrammetry data acquisition systems at home and abroad have the same working principle, system structure, working ...

AI Technical Summary

Problems solved by technology

[0003] At present, the road photogrammetry data acquisition systems at home and abroad still have the following problems: (1) Field operations cannot be carried out, and the scope of work is limited to roads: the mobile road measurement system (road photogrammetry data acquisition system) is a combination of GPS (Global Positioning System), Advanced sensors and equipment such as CCD (video system), INS (inertial navigation system or dead reckoning system), and on-board computer system are assembled on the car, which means that it can only be used for road photogrammetry and cannot be used in the field environment. (2) The movement and operation of the system itself are inconvenient: the equipment that makes up the system is large in size and weight, and the equipment is connected by cables

The structure of the system is loose, it must be fixed on a large carrier such as a car, and operated by multiple people; (3) Single function, low work efficiency: only on the road for location photogrammetry data collection and no data transmission function, this kind of external The traditional work methods of data collection and post-processing in the field lead to unavoidable and time-consuming, money-consuming, and labor-intensive work in the field; (4) Expensive: all components of the mobile road measurement system are outsourced, and these high-end The high price of equipment keeps the cost of "mobile road measurement system" high. The price of the domestic product LD2000 series mobile road measurement system (road photogrammetry data acquisition system) is 3 million yuan per set, and foreign products are more expensive
