Problems solved by technology

Since ordinary camera devices mainly observe visible light, they are satisfactory for visible light observation during the day, but they cannot "observe" light of other wavelength bands, for example, they do not have the ability to observe low-light and foggy weather
At present, there are multi-band cameras with the help of switching optical lens groups. This multi-band camera can perform normal observations under various meteorological conditions such as day, night, and haze weather, and can be used in many fields, but it is expensive and difficult to use. The cost is too high to be widely used in the general monitoring field

Embodiment Construction

[0022] The present invention will be further described in conjunction with embodiment and accompanying drawing now.

[0023] Depend on figure 1 , the multi-band rear focus CCD imaging device of the present invention mainly includes one or a group of multiple CCD circuit boards 12, and the CCD circuit board is provided with a CCD sensor chip 12a and digitizes the optical image obtained by the sensor chip. The processing microprocessor chip also includes a filter switching unit and an automatic focusing part. The whole device is located on the frame structure with the seat frame 6 as the upper layer, the filter seat 10 as the lower layer, and connected with the connector 25. The CCD circuit board provided with the CCD sensor chip 12a can be moved up and down on the seat. On the lower side of the frame, the light-receiving window of the CCD sensor chip faces downward.

[0024] The filter switching unit includes a filter holder part and a transmission part: the filter holder par...

Abstract

The invention relates to a method and a device for upgrading a common charge coupled device (CCD) camera device into a multi-waveband CCD camera device. The method and the device are used for modifying an installation method for a CCD circuit board which is mainly provided with a CCD sensor chip and a microprocessor chip performing digitalized processing on optical image data acquired by the sensor chip and modifying an optical filter unit. The method comprises the following steps of: arranging a frame structure of which the top layer is a seat frame, and arranging the CCD circuit board on the lower side of the seat frame in an up-and-down movement mode; and arranging an optical filter switching unit for switching various optical filters; and arranging an electric focusing unit to compensate focus changes after the optical filters are switched. By the method and the device, the conventional common CCD single board computers or CCD cameras can be conveniently upgraded into multi-waveband cameras at low cost, and the work capacity of the devices is greatly improved. Only electrical elements and parts are used in the method and the device, control circuits are not required to be electrified usually, and the optical filters can be electrified instantly only when required to be switched and focused, so that the method and the device are energy-saving and reliable.

Description

technical field [0001] The invention relates to the technical field of photoelectric detection, in particular to a method for upgrading an ordinary CCD imaging device to a multi-band CCD imaging device, and a multi-band rear focus CCD imaging device. Background technique [0002] Ordinary CCD cameras have been widely used in various fields. Described CCD camera head generally comprises a CCD circuit board that is formed by the microprocessor of CCD sensor chip and the optical image that this sensor chip acquires digital processing (generally described CCD sensor chip and microprocessor are integrated in one or digital A circuit board, called a CCD circuit board), and place the circuit board in a sealed case with a viewfinder window. The image signal processed by the microprocessor can be output to the display for display or / and stored in the memory through the video cable. Sometimes, circuit board parts including only CCD sensor chips and microprocessors are also sold sepa...
