Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of image acquisition auxiliary equipment, and particularly relates to a fixing clamp suitable for a lightweight real scene acquisition device. BACKGROUND

[0002] The existing lightweight real scene acquisition device usually relies on a fixing clamp to fix an imaging device, and the imaging device is usually a mobile phone. However, the existing fixing clamp has the following significant defects:

[0003] The lightweight real scene acquisition device usually needs to cover a wide range of 360° horizontal view and 150° vertical view, and the existing fixing clamp is difficult to accurately adjust the lens of the imaging device to the best position. If the lens is offset, the structure of the lightweight real scene acquisition device, such as a support or a clamping part, may appear in the imaging picture, affecting the data integrity and the accuracy of the later three-dimensional reconstruction. In order to ensure stability, the fixing clamp usually exerts a large clamping force, so that the imaging device is difficult to be adjusted horizontally after being clamped. If the position of the imaging device needs to be adjusted, the fixing clamp usually needs to be completely loosened and reinstalled, which is tedious and time-consuming.

[0004] In addition, the existing lightweight real scene acquisition device generally relies on high-resolution imaging and AI depth estimation technology, and the spatial position stability of the imaging device is required to be very high. If the fixing clamp cannot achieve a balance between flexible adjustment and rigid locking, it will directly lead to geometric distortion or texture misplacement of the three-dimensional reconstruction model.

[0005] In view of the above problems, a clamping mechanism that takes into account the horizontal adjustment flexibility and locking stability is needed to avoid imaging defects caused by the device's own structure into the mirror or displacement, and to adapt to the high-precision and high-efficiency requirements of the lightweight real scene acquisition device.

Obviously, the embodiments described in this application are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0028] Please refer to Figure 1 and Figure 2 , the light real scene acquisition device comprises an angle adjusting mechanism 1, an imaging device 3, and a fixing clamp 2 clamping the imaging device 3, the fixing clamp 2 is fixedly connected with the angle adjusting mechanism 1 and is driven by the angle adjusting mechanism 1 to change the angle, the fixing clamp 2 comprises a fixing clamp body 21, two clamping parts 22 respectively arranged at the side edges of the fixing clamp body 21, and an elastic member arranged between the fixing clamp body 21 and the clamping part 22, the clamping part 22 can slide relative to the fixing clamp body 21 to clamp the imaging device 3, and the elastic member is used to provide clamping force for the clamping part 22 clamping the imaging device 3.

[0029] Please refer to Figure 3 , the clamping part 22 comprises a clamping block 221, at least two rolling assemblies 222, and a locking assembly 223 corresponding to the rolling assembly 222, the clamping block 221 is provided with a receiving groove 221-a, the receiving grooves 221-a of the two clamping blocks 221 are oppositely arranged, the rolling assembly 222 comprises a rolling cavity and an adjusting roller 222-a arranged in the rolling cavity and rolling connected with the clamping block 221.

[0030] The adjusting roller 222-a is used for adjusting the lateral movement of the imaging device 3, and the locking assembly 223 is used for locking the adjusted adjusting roller, so as to avoid the adjusting roller from shaking or moving the imaging device 3.

[0031] The rolling cavity is arranged below the receiving groove 221-a and communicates with the receiving groove 221-a, a communication port is formed at the communication position of the rolling cavity and the receiving groove 221-a, the adjusting roller 222-a is partially exposed from the communication port, the rotating shaft 222-d of the adjusting roller 222-a penetrates through the clamping block 221, the locking assembly 223 is fixedly arranged on the clamping block 221, the locking assembly 223 is close to the rotating shaft 222-d of the corresponding rolling assembly 222 and can limit the rotation of the rotating shaft 222-d to fix the adjusting roller 222-a.
