Description

Technical Field

[0001] The invention relates to the field of physical evidence imaging, and in particular to an automated pan-tilt platform for physical evidence endoscopic imaging. Background Art

[0002] At present, for physical evidence that is difficult to observe, the method of breaking and dismantling is adopted to observe its internal structure and inspection traces. However, since the damage of physical evidence is irreversible, there are great risks and high costs. For example, in the frequent cases of burglary using technical unlocking, the grassroots are more subjective in judging technical unlocking cases, which makes it very difficult to characterize and link cases. Because it is impossible to break the locks in every case, the cost is too high. Therefore, it is extremely necessary to use portable and easy-to-operate investigation tools to investigate the locks. In the inspection and identification of guns and the investigation of explosive devices, because they are all small parts of non-standard devices, many structures are handmade. If they are disassembled, they are likely to cause irreversible damage. The use of tiny investigation equipment that can penetrate deep into the small parts can solve this problem.

[0033] Working principle: When the PTZ 2 is used for endoscopic detection of physical evidence, corresponding operations can be performed according to the needs.

[0034] First, when it comes to endoscopic detection of a non-detachable keyhole, the stage 6 can be adjusted by rotating the third screw 61 to slide down to the upper surface of the support seat 1, and then the pan-tilt 2 can be moved and placed at the object to be tested, and supported by the lifting frame 11. When the lifting frame 11 is supported, its support height can be adjusted, and the lifting and sliding adjustment of the lifting rod 13 can be controlled and adjusted by rotating the fourth screw 15, so that the corresponding use height of the probe 53 on the pan-tilt 2 corresponds to the keyhole of the object to be tested, and then the pan-tilt 2 can be adjusted again, so that the probe 53 is inserted into the corresponding keyhole to perform corresponding endoscopic detection.

[0035] During detection, the connecting rod 7 at the right end of the supporting seat 1 can be pulled outward, and the U-shaped seat 71 on it can be clamped on the door panel of the object to be detected, and then the clamping rod 72 can be rotated to clamp and limit the door panel of the object to be detected, so as to prevent the object to be detected from shaking randomly during the endoscopic detection of its keyhole, thereby affecting the detection.

[0036] Secondly, when it comes to endoscopic detection of small movable objects to be tested, such as parts of firearms and explosives, the stage 6 is adjusted by rotating the third screw 61 to extend it upward, and the object to be tested is placed on the stage 6 for detection. When the stage 6 is extended, the laser head 36 is turned on, and the laser beam is emitted to facilitate the quick positioning and adjustment of the height of the stage 6, so as to facilitate the endoscopic detection of the object to be tested placed thereon. After the object to be tested is adjusted and placed, the pan / tilt 2 can be adjusted and controlled again, so that the probe 53 extends into the interior of the object to be tested for endoscopic detection.

[0037] For the endoscopic detection in the above two cases, the pan-tilt head 2 is adjusted and controlled accordingly according to the needs. The pan-tilt head 2 is composed of a first slide 3 and a second slide 4. The first slide 3 can be controlled to move and adjust along the left and right directions of the support seat 1 under the rotation adjustment of the first screw 31, thereby controlling the insertion or extraction of the probe 53 on the object to be tested. The second slide 4 can be controlled to move and adjust along the front and back directions of the first slide 3 under the rotation adjustment of the second screw 41, and then when the probe approaches the object to be tested, it is adjusted to align with the corresponding keyhole or fine hole of the object to be tested, so that the probe 53 can accurately extend into the interior of the object to be tested.

[0038] When the probe 53 detects, the detected image can be displayed on the imaging display screen 54 for easy viewing by the user. After installation, the probe 53 can be inserted into the limit rod 35 in the slideway 34 on the upper side plate 33 of the first slide 3, and the limit rod 35 can provide auxiliary limit support to ensure its safety and stability during use.
