Description

Quick plane image acquiring device

Technical field

The present invention relates to acquisition technology field, particularly quick plane image acquiring device.

Background technology

Line of the each surface sweeping of linear array CCD scanning instrument of the prior art, be combined into a complete image by the movement of stepping motor, scanning one page image needs even more exposure frequency several ten thousand times, causes like this general image to complete the time that typing need to be longer.And the image having needs various multicolour pattern to regulate the requirement that could meet people, the operation that just can be convenient for people to.

Summary of the invention

For the problems referred to above, the object of this invention is to provide one and can adjust collection image area size, also can generate the collector of coloured image and black and white.。

Realize technical scheme of the present invention as follows:

Quick plane image acquiring device, comprise the framework and the area source that support paper, the Sensor module that at least one is made up of array image sensor and optical imaging lens head part and a corresponding circuit module, described Sensor module is arranged on the lowering or hoisting gear of base of frame, is also provided with the glass-mirror with color sensor above Sensor module.

The described glass-mirror two ends with color sensor are fixedly connected with by the motion bar that forms rectangle, motion bar is hinged and framework two ends again, the outside, two ends that motion bar is connected with framework is provided with segment that can horizontal displacement, advantage is the position of being convenient to regulate glass-mirror, to gather black and white or colored image information.

Described motion bar is connected by roller arm with framework, and one end of roller arm is fixed by screws on motion bar, and the other end is connected on framework by pulley, is convenient to stretching and the indentation of motion bar.

Described framework is provided with pulley wants the slide rail adapting to, and advantage is to be convenient to sliding up and down of pulley.

Described lowering or hoisting gear is by base, guide post, motor, threaded rod forms, and base center is provided with the screwed hole of sheathed threaded rod, and motor head is connected with threaded rod, guide post is symmetricly set on base both sides, advantage is base to be moved up and down by drive motors, thereby adjusts the height of Sensor module, thereby reaches the IMAQ of zones of different size.

Described corresponding circuit module also comprises: CPLD and CPU, and this CPLD module connects Sensor module, and CPU connects CPLD module and Sensor control module.

Adopt above-mentioned scheme, light source by area source enters glass-mirror, undertaken being transmitted in each Sensor module and carrying out IMAQ after color adjustment by color sensor, generate afterwards complete coloured image, or by pulling the motion bar of the outside side of framework, pulley is to bottom offset, then can movable glass minute surface, Sensor module is directly carried out information gathering, generate black and white image, again can be by adjusting the height of lowering or hoisting gear, can gather the image information of zones of different scope, not only simple to operate, and can gather the image of different colours.

Embodiment

Below in conjunction with the drawings and specific embodiments, the present invention is further described.

Shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, quick plane image acquiring device, comprise the framework 1 of area source and support paper 2, the Sensor module 3 that at least one is made up of array image sensor and optical imaging lens head part and a corresponding circuit module, described Sensor module 3 is arranged on the lowering or hoisting gear 9 of framework 1 bottom, and Sensor module 3 is also provided with the glass-mirror 5 with color sensor above.

Described glass-mirror 5 two ends with color sensor are fixedly connected with by the motion bar 4 that forms rectangle, motion bar 4 is hinged and framework 1 two ends again, the outside, two ends that motion bar is connected with framework is provided with segment that can horizontal displacement, advantage is the position of being convenient to regulate glass-mirror 5, to gather black and white or colored image information.

Described motion bar 4 is connected by roller arm 6 with framework 1, and one end of roller arm 6 is fixed by screws on motion bar 4, and the other end is connected on framework 1 by pulley 7, is convenient to stretching and the indentation of motion bar 4.

Described framework 1 is provided with pulley 7 wants the slide rail 8 adapting to, and advantage is to be convenient to sliding up and down of pulley 7.

Described lowering or hoisting gear 9 is by base 10, guide post 11, motor 12 and threaded rod 13 form, base 10 centers are provided with the screwed hole 14 of sheathed threaded rod 13, motor 12 heads are connected with threaded rod 13, and guide post 11 is symmetricly set on base 10 both sides, and advantage is by drive motors 12, base 10 to be moved up and down, thereby adjust the height of Sensor module 3, thereby reach the IMAQ of zones of different size.

The Sensor module adopting in the present invention is existing current techique, function be by a lens group by image imaging on Sensor, and Sensor can be converted to the signal of telecommunication by image.All on sale on market.

As seen from Figure 3, the present invention includes Sensor module, Sensor control module, CPU module, CPLD module:

Sensor module is the module of actual acquisition image, comprises array image sensor and optical imaging lens head part, can have one or more Sensor module in a cover system;

Sensor control module control Sensor gathers image, sets relevant parameter, simultaneously can be by image transmitting to computer or other system;

CPU module solves the switching problem between different Sensor, this is because by the multiple Sensor modules of a set of Sensor control module control, main system also can only be accepted the data of a Sensor module at one time, and therefore deciding current which Sensor module by a CPU module is the module using;

CPLD module is the module of setting in order to solve the timeliness that different Sensor switch, because each Sensor required regular hour from closed condition to starting state can affect IMAQ speed.Therefore increase a CPLD module all Sensor are all set to opening, all data-signals are all read into simultaneously; Then determine that according to the control command of CPU module the data of which Sensor are that current active data is processed or transmits.

As far as possible even in order to ensure the image of each Sensor collection, adopt illuminated by surface light source;

Because area source two sides has meeting luminous, therefore need to be in the impact of background correction light in image.

Host starts after IMAQ, area source powers up to be lighted, CPU module is chosen Sensor successively, the Sensor that CPLD chooses according to CPU processes or transfers to Host end by the effective image of the Sensor of current active, all Sensor data are all processed or end of transmission carries out Image Mosaics and image processing according to the calibration results afterwards again, obtain complete high quality graphic.
