Problems solved by technology

The CAMIS optical head adopts 4 Sony XC-8500CE 1 / 2″CCD black and white cameras; the main control computer adopts a half-height desktop computer, equipped with a 4-channel image acquisition card, and a differential GPS receiver; it has the function of unmanned automatic operation; Its weight: the optical head is 1.8kg, the main control computer is 9.1kg, and the liquid crystal display is 5.8kg, but CAMIS has the following disadvantages: 1. The main control computer adopts a traditional desktop system, and the weight and volume are still relatively large; 2. No anti-vibration Design; 3. No remote control function; 4. The power requirements of the main control computer are inconsistent with those provided by the aircraft, and an additional power converter is required

Embodiment Construction

[0025] The following is based on figure 1 ~ Fig. 7 provides a preferred embodiment of the present invention, describes in detail the details and working conditions of the specific multispectral imager proposed according to the present invention.

[0026] like figure 1 As shown, the multispectral imager can be divided into two parts: an optical head 1 and a main control computer 2 , and the optical head 1 and the main control computer 2 are connected by three cables 3 . The optical head 1 is made up of three black and white CCD cameras 4 and a housing 5 . Three CCD cameras 4 are evenly arranged in an equilateral triangle (see image 3 shown), and parallel to each other on the optical axis. In order to ensure the registration of multi-spectrum image pixels, the parallel accuracy must be controlled within 1 / 4 pixel. In order to achieve parallel accuracy, a precision machined housing is used. Each camera 4 is equipped with a lens 6 and a narrow band filter 7. The filter 7 wi...

Abstract

A multispectrum imager for monitoring carried by unmanned machine with small carrying capacity, can synchronously obtain remote sensing image combined by multi-wave-range images, especially suitable for carrying out ocean monitoring task. Its main control computer uses PC / 104 + computer in stead of traditional desktop computer, making its mass and volume reduced a lot, satisfying requirement of small room and load of unmanned machine; outer shell uses levitation type spring structure to strengthen its ability of resistance to impact and vibration; supporting automatic monitoring software is installed to realize automatically control and time interval time and exposure time of synchronous shot, receive and carry out long-distance command.

Description

Technical field: [0001] The invention relates to a light and small multi-spectral imager, in particular to a miniaturized, lightweight, automated, low-power unmanned aerial vehicle-mounted marine remote sensing multi-spectral imager, which is suitable for loading on a small unmanned aircraft Rapid dynamic monitoring of offshore red tides, oil spills, sea ice and other phenomena and emergency monitoring of maritime emergencies. technical background: [0002] Small unmanned aircraft is a new type of remote sensing platform that has developed rapidly in recent years. Its outstanding advantages are low cost and flexibility. However, due to its light load and small space, the remote sensing instruments it carries are required to be miniaturized, lightweight, and low in power consumption; there are no operators on board, and the remote sensing instruments are required to have the ability of automatic control and remote control. [0003] The multi-spectral imager is an effective m...
