[0031] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0032] See also Figure 1 , Figure 2The camera mounting seat provided in this embodiment includes a base 100 and a fixing assembly. A pitch adjustment seat 110 is provided at the bottom of the base 100, and three mounting portions 120 are provided on the top surface of the base 100. The three mounting portions 120 are provided on the top surface of the base 100 and are distributed along a straight line, and the middle mounting portion 120 is used to set the infrared camera 300 or the front mirror 500. The mounting portion 120 includes a support platform, and a mounting screw hole 122 is provided on the support platform. The fixing assembly includes a plurality of locking members, which are detachably connected to the base 100 to fix the infrared camera 300.

[0033] Among them, the three mounting parts 120 in this embodiment can simultaneously carry two visible light cameras 400 and one infrared camera 300. When debugging, first locate the position of the base 100. Specifically, the front mirror 500 needs to be installed on the mounting part 120 located in the middle of the top surface of the base 100 and aligned with the collimator 600 so that the front mirror 500 is parallel to the collimator 600 to achieve the location of the mounting seat.

[0034] Subsequently, the front mirror 500 is disassembled, and the visible light camera 400 and the infrared camera 300 are installed respectively, and the height of the support table is adjusted so that the light output height of the infrared camera 300 and the light output height of the visible light camera 400 are flush with the collimator 600, and the angles of the infrared camera 300 and the visible light camera 400 are fine-tuned so that the light output of the infrared camera 300 and the light output of the visible light camera 400 are parallel to the collimator 600. After that, the infrared camera 300 and the visible light camera 400 are locked and fixed on the mounting seat to achieve the parallelism adjustment of the three optical axes.

[0035] The camera mounting seat provided in this embodiment has a simple structure and high adjustment efficiency.

[0036] In this embodiment, the support platform includes at least three bosses 121. The multiple bosses 121 are evenly distributed and enclosed to form a support platform, the top surface of the boss 121 is the support surface, and the mounting screw holes 122 are provided on the support surface.

[0037] The boss 121 is used to support and bear the infrared camera 300 or the visible light camera 400, and the supporting surface is used to bear the bottom of the infrared camera 300 or the visible light camera 400. When the height is too high, the height of the boss 121 can be reduced by grinding so that the light output height of the visible light camera 400 or the infrared camera 300 is at the same height as that of the collimator 600, so as to adjust the optical axis.

[0038] Moreover, the three bosses 121 can form a triangular structure of stable support, thereby achieving support for the visible light camera 400 or the infrared camera 300. After the support is stable, the visible light camera 400 or the infrared camera 300 is locked on the boss 121 by passing the screws through the base 100 of the visible light camera 400 or the infrared camera 300 and then screwing them into the mounting screw holes 122.

[0039] In this embodiment, there are four bosses 121. The four bosses 121 are distributed in a rectangular shape.

[0040] The four bosses 121 are distributed in a rectangular shape to support the four corners of the visible light camera 400 or the infrared camera 300 , thereby realizing a stable supporting structure.

[0041] In this embodiment, the fixing assembly includes a plurality of clamps 200. A plurality of locking openings are provided on the top surface of the base 100, and the plurality of locking openings are evenly distributed along the circumference of the base 100. Both ends of the clamps 200 are detachably connected to the locking openings.

[0042] Specifically, in this embodiment, the locking openings are arranged on both sides of the mounting portion 120 located in the middle of the base 100, and the two ends of the clamp 200 are respectively locked in the locking openings on both sides of the mounting portion 120. The middle position of the clamp 200 presses the infrared camera 300 onto the boss 121, further improving the connection stability between the infrared camera 300 and the base 100.

[0043] In this embodiment, there are two clamps 200. The two clamps 200 are arranged at intervals and are connected to the base 100 respectively.

[0044] The two clamps 200 can fix the front and rear positions of the infrared camera 300, further improving the stability and preventing the infrared camera 300 from shaking and changing its angle.

[0045] In this embodiment, the pitch adjustment seat 110 is a wedge-shaped base 100. The bottom end of the wedge-shaped base 100 is an inclined surface structure.

[0046] Specifically, during debugging, the wedge-shaped base 100 can be moved along the inclined plane to adjust the height of the wedge-shaped base 100 , thereby adjusting the height of each component on the base 100 .

[0047] See also Figure 3 The optical axis adjustment device provided in this embodiment includes a collimator 600, a front mirror 500 and a provided camera mounting seat. The collimator 600 has a light emitting portion. The front mirror 500 has an alignment mark, and the front mirror 500 can be detachably mounted on a support table located in the middle of the camera mounting seat, and the front mirror 500 is opposite to the collimator 600 and the lens faces the light emitting portion.

[0048] Specifically, Figure 3 It is a schematic diagram of the structure during the debugging process. First, the base 100 is fixed, and then the front mirror 500 is installed on the mounting portion 120. The height of the base 100 is adjusted so that the lens height of the front mirror 500 is flush with the height of the light-emitting portion of the collimator 600. Then, the angle of the base 100 is adjusted so that the lens of the front mirror 500 faces the light-emitting portion of the collimator 600. The angle of the base 100 is further adjusted so that the alignment mark in the front mirror 500 coincides with the light of the collimator 600. At this time, the camera mounting seat is aligned. In this position, the camera mounting seat is in the alignment position, and the front mirror 500 is removed from the camera mounting seat.

[0049] Specifically, after the camera mounting base is in the alignment position, the visible light camera 400 and the infrared camera 300 can be installed. First, the infrared camera 300 is installed on the mounting portion 120 located in the middle of the top surface of the base 100, and the direction of the infrared camera 300 is finely adjusted so that the optical axis of the infrared camera 300 is parallel to the light output of the collimator 600. Then, the visible light camera 400 is installed and finely adjusted in turn so that the optical axis of the visible light camera 400 is parallel to the light output of the collimator 600, thereby achieving the adjustment of the parallelism of the three optical axes.

[0050] The detection device provided in this embodiment includes an infrared camera 300, a visible light camera 400 and a provided camera mounting seat. There are two visible light cameras 400, and the infrared camera 300 and the visible light camera 400 are respectively arranged on three mounting parts 120 of the camera mounting seat, and the two visible light cameras 400 are respectively located on both sides of the infrared camera 300.

[0051] After the camera mounting base is aligned by cooperating with the front mirror 500 and the collimator 600, the front mirror 500 is removed, and the infrared camera 300 and the visible light camera 400 are installed and adjusted in sequence to adjust the parallelism of the three optical axes.

[0052] In this embodiment, the fixing assembly further includes a connecting bolt 210. Both the visible light camera 400 and the infrared camera 300 have a connecting hole. The position of the connecting hole is opposite to the position of each mounting screw hole 122 of the camera mounting seat. The hole diameter of the connecting hole is larger than the diameter of the screw rod of the connecting bolt 210 and smaller than the diameter of the nut of the connecting bolt 210.

[0053] Specifically, when fine-tuning the infrared camera 300 and the visible light camera 400, taking the infrared camera 300 as an example, the infrared camera 300 has a base 100, and a connecting hole is provided on the base 100 of the infrared camera 300. The infrared camera 300 is placed on the mounting seat so that the connecting hole of the base 100 of the infrared camera 300 abuts against and communicates with the mounting screw hole 122 on the mounting seat. The connecting bolt 210 is inserted so that the front end of the screw of the connecting bolt 210 is screwed into the connecting screw hole without tightening the screw. Since the aperture of the connecting hole is larger than the diameter of the screw of the connecting bolt 210, at this time, the infrared camera 300 can be moved slightly, thereby fine-tuning the angle of the infrared camera 300 so that the optical axis of the infrared camera 300 is parallel to the light output of the collimator 600. After the optical axis of the infrared camera 300 is parallel to the light output of the collimator 600 , the connecting bolt 210 is tightened to press the nut against the base 100 of the infrared camera 300 , thereby fixing the position of the infrared camera 300 and adjusting the infrared camera 300 .

[0054] Accordingly, the two visible light cameras 400 are sequentially mounted on the mounting portion 120 and adjusted in the same manner, thereby achieving adjustment of the parallelism of the three optical axes.

[0055] In this embodiment, the detection device further includes a control system, which is electrically connected to the visible light camera 400 and the infrared camera 300 .

[0056] The control system can realize the opening and closing of the visible light camera 400 and the infrared camera 300 , and the display of the data received by the visible light camera 400 and the infrared camera 300 , so that the user can make an accurate judgment.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model.
