Embodiment 1

[0042] A method for constructing a mobile phone 3D model to guide image comprehensive acquisition related to this embodiment, its specific process steps are as follows:

[0043] 1. Use the mobile phone sensor to obtain angle data, where the angle data includes compass horizontal geomagnetic angle data and mobile phone inclination data; specifically:

[0044] (1) Obtain the compass horizontal geomagnetic angle data of the mobile phone camera through the mobile phone sensor, and obtain the horizontal angle value in the range of 0-360 angles, which is used to mark the horizontal angle of the current photo;

[0045] (2) Use the mobile phone sensor to obtain the mobile phone tilt angle data of the mobile phone camera (photograph pitch angle, that is, the angle of the mobile phone body on the side of the mobile phone camera relative to the horizontal plane), to mark the current mobile phone pitch angle;

[0046](3) Taking the mobile phone as the center of the circle, subdivide the 3...

Embodiment 2

[0067] The angle of view of the hemispherical 3D model constructed in Example 1 will change with the sensor of the mobile phone when the camera angle changes, such as Figure 6 As shown, the angle of view of the hemispherical 3D model on the screen of the mobile phone when the pitch angle of the mobile phone is 0 degrees; Figure 7 As shown, the viewing angle of the hemispherical 3D model on the screen of the mobile phone when the pitch angle of the mobile phone is 60 degrees; Figure 8 As shown, the viewing angle of the hemispherical 3D model on the screen of the mobile phone when the pitch angle of the mobile phone is 90 degrees; Figure 9 As shown, after using the mobile phone to take pictures of the desktop items when the pitch angle of the mobile phone is 60 degrees, the semi-spherical 3D model is marked with a corresponding color change. By observing the marked semi-spherical 3D model, it can be known that continuous multi-angle After the photo taking process, users can...

Embodiment 3

[0069] Embodiment 1 relates to a method for constructing a mobile phone 3D model to guide comprehensive collection of images, which can be applied to the field of 3D modeling. When performing 3D modeling, the method described in Embodiment 1 is used to take pictures of the modeled object in all directions and from various angles , the image collection of each angle is comprehensive, and the angle data is used to participate in the modeling, which is conducive to the rapid completion of 3D modeling, making the established model closer to the real object, and the modeling effect is better; the construction of the mobile phone 3D model guides the image to be comprehensive The method of collection can also be used for shooting panoramic photos. The method described in Embodiment 1 is used to collect images from all directions and angles to the environment, and the angle data are used together for panoramic image modeling, and the panoramic level after modeling Clear, comprehensive ...

Abstract

The invention belongs to the technical field of picture information acquisition, and relates to a method for constructing a mobile phone 3D model to guide comprehensive image acquisition. The method comprises the following process steps of: 1, acquiring angle data by using a mobile phone sensor; 2, performing mark calculation on a photographing angle of a picture by referring to the acquired angledata; and 3, feeding back the marked photographing position to a user in real time through a semi-spherical 3D model constructed by a mobile phone, wherein the marking degree of the semi-spherical 3Dmodel represents the image acquisition degree, and it is determined that data acquisition is completed when marking of the whole semi-spherical 3D model is completed. According to the method, the 3Dmodel is constructed in the mobile phone to guide the user to adjust the photographing angle, so that the picture information is accurately acquired, the photographing angle acquired each time is marked in the constructed 3D model, and the comprehensiveness and high efficiency of real object image information acquisition are ensured.

Description

Technical field: [0001] The invention belongs to the technical field of picture information collection, and relates to a method for guiding users to collect picture information by using mobile phone sensor data and a 3D mode, in particular a method for building a mobile phone 3D model to guide comprehensive image collection. Background technique: [0002] At present, there are many ways to collect picture information, such as shooting by camera, recording by camera, recording by monitoring equipment, scanning by scanning equipment, or taking pictures by mobile phone. It is necessary to take pictures at an angle or in all directions, but due to the large number of angles and the large number of pictures, it is difficult to ensure that the images of all positions of the target object are collected. The omission of a certain camera angle may cause immeasurable troubles to the later image processing, especially If the location of the object is far away from the working point of ...
