Problems solved by technology

However, in practical applications, it is found that unless there is an accurate angle measurement device, the user is not sensitive to the angle, and it is difficult to determine the angle accurately; the size of the target object is difficult to accurately determine, especially in some applications where the target object needs to be replaced frequently. A lot of extra work is required, and professional equipment is required to accurately measure irregular targets
Measurement errors lead to camera position setting errors, which will affect the speed and effect of acquisition and synthesis; the accuracy and speed need to be further improved

Embodiment 1

[0048] In order to solve the above technical problems, an embodiment of the present invention provides a three-dimensional acquisition module for a mobile terminal. like Figure 1-Figure 8 As shown, it specifically includes: a data interface, a lifting device 1 , a rotating device 2 and an image acquisition device 3 .

[0049] Wherein the image acquisition device 3 is arranged on the rotation device 2, and the rotation device 2 is arranged on the lifting device 1, through the extension and contraction of the lifting device 1, all / part of the rotation device 2 and the image acquisition device 3 can be stored in the mobile phone casing, or exposed case. The lifting device can be a slide rail, a telescopic rod or the like. The elevating device 1 can be driven by an elevating drive device for automatic elevating, or can be manually elevated by the user through pushing and pulling.

[0050] The rotating device 2 can drive the image acquisition device 3 to rotate, so that the ima...

Embodiment 2

[0067] Referring to the content of Embodiment 1, in addition, the mobile terminal may not have a lifting device, or although it has a lifting device, it may not need a lifting device to lift the image acquisition device out of the mobile terminal shell during acquisition. At this time, both the rotating device 2 and the image acquisition device 3 are located in the casing of the mobile terminal. The rotation device 2 can still drive the image acquisition device 3 to rotate, but this time the mobile terminal housing corresponding to the rotation area of ​​the image acquisition device 3 should be made of a light-transmitting material, such as a transparent resin material. Therefore, the image acquisition device 3 can still scan and acquire images without being exposed to the outside of the casing. Of course, if the image acquisition device 3 is an infrared camera, then the light-transmitting material only needs to transmit infrared light, not visible light. That is to say, the ...

Abstract

The present invention provides a mobile terminal with a lifting and rotating 3D acquisition device, including a lifting device, a rotating device, and an image acquisition device; wherein the lifting device, the rotating device, and the image acquisition device are connected in sequence; in the non-use state, the lifting device, Both the rotating device and the image acquisition device can be partly or completely accommodated in the mobile terminal housing; in the state of use, the light entrance of the image acquisition device is exposed outside the mobile terminal housing. The image acquisition device is connected with the mobile terminal for data. It is the first time to propose a device structure that can apply the principle of image stitching for 3D acquisition in a mobile terminal. For the first time, it is proposed to use the method of rotating the camera on the horizontal plane to scan the target in the mobile terminal to achieve 3D synthesis, avoiding the excessive volume caused by the use of too many tracks, and avoiding the difficulty of synthesis caused by free movement.

Description

technical field [0001] The present invention relates to the technical field of object acquisition, in particular to the technical field of three-dimensional acquisition of a target by using a camera in a mobile terminal. Background technique [0002] Currently common 3D acquisition methods include structured light method and laser scanning method, but these methods require the installation of light sources and beam shaping systems, which are costly, consume a lot of power, and take up a lot of space. [0003] At present, mobile phones usually have 1-3 cameras, so as to achieve some special shooting effects, such as blurring the background. But there is currently no camera system that can be used for 3D capture on mobile phones. If only the current camera system is used, due to the limited shooting angle, it is difficult to perform 3D stitching and 3D images cannot be obtained. If you want to increase the shooting angle and increase the redundancy of the captured images, yo...
