Description

[Detailed Description of the Invention] ゛ [Industrial Application Field] The present invention is a continuous image creation recorder capable of creating and recording continuous images of a long continuous sample such as a ground sample obtained in a polling survey. The present invention relates to an apparatus and a method for creating continuous images and creating three-dimensional continuous images.

[Prior Art] Conventionally, this type of device is as follows.

Earth 1! During survey polling in r-surveys, continuous ground samples are collected, organized and stored in sample boxes.

On the other hand, the condition of long samples changes over time due to repeated drying and wetting and freezing and thawing after collection, so it is necessary to record the condition immediately after collection as soon as possible.

For this reason, it is common to take photographs to record and preserve the state of the sample immediately after collection.

[Problems to be Solved by the Invention] The prior art described in the prior art had the following problems.

A. When storing in a sample box.

Due to the large weight of the sample and the large size of the sample box, it was not easy to handle and it was difficult to use it repeatedly.

In addition, in order to store a large number of long samples, a large-scale building is required because it occupies a large area.

B. In the case of photo tit shadows, taking the photo itself is a time-consuming and expensive task, and if the entire polling section is to be photographed, each sample box must be photographed, making it difficult to record detailed images. On the other hand, when close-up photography is performed to record detailed images, the amount of photographs becomes enormous, making it difficult to organize them.

Furthermore, frame-by-frame recording using photographs is inappropriate for recording long samples that are originally continuous.

Furthermore, because the scale at which the images were taken was not fixed, it was difficult to carry out measurements indoors using images of the sample.

In addition, the only way to record stereoscopic images is to use a stereoscopic camera that takes pictures from two directions for each frame, but this method is difficult to call simple because it requires time and money. .

The present application was made in view of the problems of the prior art, and its purpose is to provide a system that can do the following.

The present invention continuously inputs close-up images of a long sample from a certain distance using a simple method, creates and records continuous images of a predetermined scale based on this, and also creates three-dimensional images as necessary. The purpose is to record the creation of.

[Means for Solving the Problems] In order to achieve the above object, the present invention is as follows.

That is, the gist of the present invention is to provide a guide rail that is attached to a long sample at a constant distance parallel to the longitudinal direction of the sample, and a guide rail that moves parallel to the sample on the guide rail.

An image input device and a control device that accommodate a rotary encoder, an image processing device and an image recording device that accommodate an input image memory and a continuous image memory, and create digital continuous images in synchronization with the movement of the image input device, and an input image Input image to monitor TV receiver, digital ream &! The invention resides in a continuous image recording device characterized by being equipped with a television receiver for continuous image monitoring that monitors images.

A guide rail 3 equipped with an imaging distance M adjustment device r111C that is mounted parallel to the longitudinal direction of the long sample 2 and at a constant distance from the sample is installed in the polling sample box 1, and a guide rail 3 is installed on the guide rail 3 on top of this. Both image input devices 4 each having a guide roller that moves in parallel along the image input device 4 are stacked one on top of the other.

Inside the image input device 4, there is a television camera 5 that directly faces the long sample 2, an illumination device 6, a counter pulley 8, a rotary encoder 9 that generates electric pulses at regular intervals in conjunction with these, and a counter that counters the rotation of the guide roller rough. An interlocking belt 10 for transmission to the pulley 8 is installed.

Next, the image input device 4 is moved to a position where image recording is to be started, and the image input device 4 is moved in the longitudinal direction of the long sample 2 on the guide rail 3.

At this time, the guide roller rough rotates in response to the movement of the image input device 4, and accordingly, the counter pulley 8 rotates via the interlocking belt 10, and correspondingly, the rotary encoder 9 rotates the counter pulley 8 at regular intervals. Generates electrical pulses.

The image signal of the long sample photographed by the television camera 5 is transmitted to the image processing device 14, and is first captured in the input image memory 15, and is processed in one line at a fixed position using the electric pulse sent from the rotary encoder 9 as a trigger signal. The image signals of the image input device 4 are taken out, and the image signals are sequentially arranged in a column direction in a continuous image mes i6 in response to the movement of the image input device 4, which is repeated to obtain continuous digital images.

When changing from an input image to a digital continuous image, if the pixel sampling position is calculated and changed with respect to the shape of the sample to be photographed, an image without distortion can be created regardless of the shape of the sample.

Also, with one trigger signal, images of one unit row each are captured at two locations relative to the angle of view θ on the input image memory 15,
Unit row image A at the same point among two unit row images captured in the same way at a point moved by a distance corresponding to θ on the sample
′ and display them continuously in response to the movement of the television camera to create a continuous image that can be viewed stereoscopically.

The digital continuous images are monitored by the continuous image monitoring television receiver 19 and recorded by the two-image recording device 1F, so that they can be reproduced and used.
