Problems solved by technology

[0007] 1) The normal of a slope inclined to the ground surface cannot be estimated correctly
[0008] 2) Normals cannot be estimated correctly on sides other than rectangles
[0009] 3) It will wrongly judge that the color information is close to the surface of the sky and the ground
So, in this case, existing techniques cannot be used

Embodiment approach 1

[0108] First, a first embodiment of the image processing device of the present invention will be described.

[0109] This embodiment is an image processing device in the form of a camera, and its appearance is as follows: Figure 1C shown. Figure 1C The image processing device (camera 100) includes: the subject lens unit 101, which is used to acquire the polarized light image and color image information of the subject through photography; the wide-angle lens unit 102, which is arranged on the top of the camera, is used to acquire the polarized image information; and a level indicating device 103 such as a spirit level. The imaging of the subject is carried out with the camera 100 kept horizontal, the direction indicated by the horizontal pointing device 103 is the horizontal direction, and the wide-angle lens unit 102 is vertically upward.

[0110] Below, refer to figure 2 , the configuration of this embodiment will be described in more detail. figure 2 It is a function...

Embodiment approach 2

[0288] Next, a second embodiment of the image processing device according to the present invention will be described.

[0289] The image processing device according to Embodiment 1 above has a color polarized image pickup unit and can acquire luminance information of different colors. However, it is not necessary to acquire a color image in order to perform image processing according to the present invention. For example, the image processing of the present invention can also be implemented using luminance images such as monochrome images.

[0290] Figure 33 It is a block diagram of the image processing apparatus of this embodiment. for Figure 33 The difference from the first embodiment is that the image processing device has a polarization information acquisition unit 3300, including a polarization image acquisition unit 3301 and an all-sky polarization map acquisition unit 3302; The operations of the unit 3303 and the cloudy sky area separation unit 3304 are different f...

Abstract

The present invention provides an image processing device and pseudo-3D image creation device, comprising a color polarized image acquisition unit (201), full sky polarization map acquisition unit (202), weather judgment unit (203), clear sky region separation unit (204), cloudy sky normal estimation unit (207), and a pseudo-3d transformation unit (208). By this configuration, the image processing device factors in the polarization state of the outdoor sky, acquires polarization information, estimates the surface normal information of the surface of the object in the 2d image, and creates a surface normal image. Using this, the device divides the regions of the objects in the image, extracts the 3d information, and creates an image which is subjected to perspective transformation to thereby create a pseudo-3d image.

Description

technical field [0001] The present invention relates to an image processing device and a simulated stereoscopic image generating device. In particular, it relates to a pseudo-stereoscopic image generation device for estimating a three-dimensional shape from an image (two-dimensional image) without depth direction information, such as a general two-dimensional still image or moving image taken outdoors, to create a pseudo-stereoscopic image. Background technique [0002] For two-dimensional still images, in order to enjoy simulated stereoscopic images by changing the viewpoint arbitrarily, it is necessary to use various methods to obtain depth direction information that is usually used to express stereoscopic images. For this, it is sufficient to use, for example, special range finders and so-called activity detection systems, for example changing light sources. However, it is difficult to mount such a structure on a camera for general civilian use. [0003] Therefore, a me...
