Because any object in the CV image has the three dimensional coordinates, it is possible to observe it by fixing the object that move, as playing video, to an arbitrary position in the picture frame. For instance, it is possible to display a target object by always fixing it in the image to the center of the picture frame. Moreover, not just display and observe an object, it is also possible to measure and analyze at the fixed position in which it displays.

3D Coordinates

Display of latitude, longitude and altitude data of an arbitrary point. Because the CV image has the camera coordinates, each pixel has the relation to the camera coordinates due to the right angled coordinate system. Especially, if the CV image is calibrated using three or more reference points, it will be possible to display an arbitrary point in the CV image by public coordinates. Naturally, if we use GPS when the video is shoot, we can make CV image with public coordinates.

3D Measurement

3D Measurement

The coordinates at an arbitrary point of any frame can be acquired, and measuring the distance between two arbitrary points becomes possible.

Three Dimensional Measurement in a Frame

3D Measurement

Because each frame of the CV image has the camera position, the coordinates at an arbitrary point of any frame can be acquired, and measuring the distance between two arbitrary points become possible.

Measurement Between Different Frames

Because each frame of the CV image has the camera position, the distance between each frame becomes already known. Moreover, each pixel in each frame becomes already known, and the distance between two arbitrary points between arbitrary frames can be acquired by calculation. All frames of the image are related in three dimensional space by the CV value.

Combination of Real Image and CG

Combination of Real Image & CG

We can put a CG into a position observed from the already known camera position. And the CG and the video can be combined without any contradiction.

Though, the image in ALV is two dimensions but 3D coordinates of an arbitrary point can be measured. Therefore, by placing CG in the arbitrary measured point, and adjusting the camera viewpoint obtained from CV value, all surround viewed image combined with the CG can be displayed without contradiction. Moreover, even when playing the Video, the CG shall be displayed and synchronized with the CV value. Thus, it is possible to draw the CG like a part of the image, with the direction and the size changed synchronizing with the surrounding images.
