Embodiment 1

[0039] like Figure 1 to Figure 4 As shown, a kind of A-117 trace inspection comprehensive instrument includes a base 77, a column 78, a microscopic camera objective lens 1, a four-section lighting ring light 2 and an ultraviolet and infrared multi-band light source 11, and the column 78 is installed on the base 77, Described microphotographic objective lens 1 is connected on the column 78 by driving device, and described driving device comprises lifting column 69, lifting motor 70, lifting rack 73, pinion shaft and rotary wheel 17, and one side opening of described lifting column 69 And be provided with a chute, the lifting rack 73 is slidably connected in the chute, the gear shaft is rotatably connected to the lifting column 69, and one end of the gear shaft is connected to the said wheel 17, and the other end is connected to the driven gear 72, the lifting motor 70 is installed on the side of the lifting column 69 and connected to the driving gear 71, the driving gear 71 is...

Embodiment 2

[0045] As another preferred mode of the present invention, on the basis of Example 1, such as Figure 12 As shown, a large field of view scanning device 8 is also included, and the large field of view scanning device 8 includes a box body, a moving device 55, a moving rack 54 and a scanning motor 53, and the moving device 55 is slidably connected to the top of the box body, A moving rack 54 is connected to the bottom surface of the moving device 55 , and a moving gear meshed with the moving rack 54 is connected to the output shaft of the scanning motor 53 . When the moving device 55 horizontally drives the large field of view object to move at a constant speed, the strip images collected by the continuously variable magnification objective lens 13 through the camera CCD target surface 15 are spliced ​​by a computer to form a large field of view scan image. This expands the field of view observation range.

Embodiment 3

[0047] As another preferred mode of the present invention, on the basis of Example 1, such as Figure 5 As shown, it also includes an all-round adjustable side light 2, and the all-round adjustable side light 2 includes a base 29, an object stage, a light frame 27, a light source 26 and an azimuth-adjustable motor 28, and the azimuth-adjustable motor 28 Installed on the top surface of the base 29, the output shaft of the azimuth-adjustable motor 28 is connected to the turntable support, the light source 26 is installed on the side of the turntable support through the lamp holder 27, and the object table 25 is connected to the top of the turntable support. The motors used in this embodiment are all manual and electric motors with dual output shafts. In this way, the hand and the computer can control the stage and the side light to perform horizontal rotation, and at the same time can control the light source 26 to rotate horizontally around the stage 25 for oblique lighting. T...

Abstract

The invention discloses a trace examination synthetic instrument, and relates to the criminal investigation judicial identification equipment field; the trace examination synthetic instrument comprises a pedestal, a column, a microscopic shooting object lens, four illumination annular lamps and an UV and infrared multiband light source, a bullet rifling scanning device, a projectile bottom bullettray viewing device, a cylinder integrating sphere scanning device, a cylinder inner wall scanning device7, a large field of view scanning device, a measuring objective table, a double-dynamic combined-image viewing device, a UV infrared multiband light source and an ultra depth of field viewing device. The trace examination synthetic instrument is large in synthetic level, novel in structure, simple in operations, low in making cost, good in social benefits, and can help criminal investigation personnel to fast solve criminal cases.

Description

technical field [0001] The invention relates to the field of criminal investigation and judicial appraisal equipment, in particular to an A-117 trace inspection comprehensive instrument. Background technique [0002] Trace inspection often refers to the inspection of hand and foot gun marks, and many instruments are used, such as stereo microscopes, physical evidence instruments, fingerprint collectors, footprint instruments, comparison microscopes, bullet bottom bomb groove instruments, and super depth-of-field observers. The operation is cumbersome, many procedures are the same, each instrument has a single function, complex structure, weak intelligence, slow processing speed, and high labor intensity for the operator. [0003] Chinese patent publication number is that CN206818135U discloses a kind of non-contact warhead mark measuring instrument, belongs to the field of police equipment. The new model includes a computer, a focus control motor, a CCD camera, an image acq...
