DETAILED DESCRIPTION

[0018] The following will be described in detail with reference to the accompanying drawings Figs. 1-3 The application will be further described in detail.

[0019] The application embodiment discloses a camera measurement bridge distance device. Referring to Figs. 1-3 A camera measurement bridge distance device, comprising a sleeve 1, a lifting assembly 2, a mounting frame 3 and a camera 4;

[0020] Among them, the sleeve 1 is the support and installation basis of the whole device, which provides a stable installation platform and protective shell for other components. The internal space provides the necessary range of motion for the lifting of the mounting frame 3 and the telescopic directional unit 203, and the structural strength of the sleeve 1 can withstand the stress of the whole device under different working conditions, ensuring the overall stability of the device.

[0021] Referring to Fig. 2 and Fig. 3, the lifting assembly 2 is the key part of adjusting the height of the camera. The winding roller 201 is installed on the sleeve 1, and is connected with the mounting frame 3 through the connecting rope 202 on the winding roller 201. This simple and direct connection can effectively convert the rotation of the winding roller 201 into the lifting movement of the connecting rope 202, so as to realize the traction of the mounting frame 3. When the winding roller 201 releases the connecting rope 202, the connecting rope 202 drives the mounting frame 3 to descend by using its own gravity; on the contrary, when the winding roller 201 winds the connecting rope 202, the connecting rope 202 pulls the mounting frame 3 to ascend. The telescopic directional unit 203 is composed of two slide rods 2033, slide blocks 2032 and a scissor folding frame 2031. The slide rod 2033 provides a stable sliding track for the slide block 2032, and the slide block 2032 slides smoothly and accurately on the slide rod 2033. The four slide blocks 2032 are hinged with the scissor folding frame 2031, so that the scissor folding frame 2031 can be flexibly unfolded and folded. The telescopic directional unit 203 is set according to the needs, and preferably three triangular distributions are adopted. In the lifting process of the mounting frame 3, the unique structure of the scissor folding frame 2031 plays an important role. When the mounting frame 3 descends, due to the gravity of the mounting frame 3 and the camera 4, the scissor folding frame 2031 is pulled to unfold and fold, and the unfolded scissor folding frame 2031 forms a stable triangular structure support system to provide stable support for the lifting of the mounting frame 3, effectively preventing the mounting frame 3 from shaking during lifting; similarly, when the mounting frame 3 ascends, the scissor folding frame 2031 still remains unfolded under the action of gravity, ensuring the stable lifting of the mounting frame 3 and the camera 4. This stable lifting mechanism can accurately adjust the height position of the camera 4, and provide accurate measurement angle and data acquisition conditions for bridge distance measurement.

[0022] Referring to Fig. 2 , the mounting frame 3 is composed of a connecting seat 301 and a support frame 302. The connecting seat 301 is connected with the connecting rope 202, and uniformly transmits the tension of the connecting rope 202 to the whole mounting frame 3. The structural design ensures the firmness and stability of the connection. The support frame 302 is used for mounting the camera 4, and the outer diameters of the connecting seat 301 and the support frame 302 are the same as the inner diameter of the sleeve 1. This size design makes the mounting frame 3 maintain good coaxiality when lifting in the sleeve 1, avoids measurement errors caused by eccentricity or shaking, and further improves the stability and measurement accuracy of the camera 4 during lifting.

[0023] The implementation principle of the camera measurement bridge distance device in the embodiment of the application is as follows:

[0024] Before the bridge distance measurement operation is performed, the sleeve 1 is fixed at a suitable measurement reference position, so as to ensure that the sleeve 1 is firmly installed, horizontal and accurately positioned.

[0025] When the height of the camera 4 needs to be adjusted, the winding roller 201 is started to work. If the winding roller 201 rotates clockwise to release the connecting rope 202, the length of the connecting rope 202 increases, and under the action of gravity, the mounting frame 3 starts to move downward. With the descent of the mounting frame 3, the scissor folding frame 2031 connected thereto starts to unfold due to the pulling of gravity. The two ends of the scissor folding frame 2031 are connected with the sliding rod 2033 through the sliding block 2032, and the sliding rod 2033 is fixed on the sleeve 1. This structure enables the scissor folding frame 2031 to extend along the sliding rod 2033 during unfolding, thereby providing stable support force for the mounting frame 3 and limiting the shaking of the mounting frame 3 in the horizontal direction.

[0026] Similarly, when the winding roller 201 rotates counterclockwise to wind up the connecting rope 202, the connecting rope 202 generates upward pulling force on the mounting frame 3, and the mounting frame 3 starts to rise. At this time, the scissor folding frame 2031 still maintains the unfolded state under the action of gravity, and with the rising of the mounting frame 3, the scissor folding frame 2031 will be folded accordingly, but always maintains stable support for the mounting frame 3, thereby ensuring that the mounting frame 3 will not shake, deviate or have other unstable phenomena during rising.

[0027] When the camera 4 reaches the appropriate height position, the work of the winding roller 201 is stopped, and the camera 4 can start the bridge distance measurement work. The camera 4 transmits the photographed bridge image to the related data processing system, and through the identification and analysis of the bridge feature points in the image and the use of related measurement algorithms, the bridge distance data is calculated. In the whole measurement process, since the camera 4 can maintain the stability of the height during the lifting process and at the measurement height position, the accuracy of the bridge distance measurement can be effectively improved, and reliable measurement data support can be provided for the bridge engineering construction, maintenance and other work.
