Description

Image and gradient signal acquisition device and virtual running system for virtual running system

The present invention relates to a video, a gradient signal acquisition device, and a virtual running system that acquire an image of a captured traveling course and a gradient signal of the traveling course.

Conventionally, in a room running device, in order for a user to practice without getting tired of running, a running course with a landscape background is recorded on a video tape, which is then played back on a video tape recorder and a television receiver. The video tape playback speed is controlled according to the detected speed of the user, and if the user speed increases, the playback speed increases accordingly. Accordingly, the playback speed is also slowed down (Patent Document 1).

Also, in order to make the training more realistic, a running device that changes the user's load according to the image of the running route has been proposed (Patent Document 2).

In the running device described in Patent Document 2, an image of the running route is generated by the image signal generating means, displayed on the CRT display, and the running route image is moved backward in the running direction according to the running speed of the user. In response to displaying the uphill running route, increasing the slope of the running means or increasing the belt running speed to increase the load on the user and displaying the downhill running route The user's image, running path and obstacles are generated in response to the fact that the load on the user is reduced by reducing the inclination angle of the running means or slowing the running speed of the belt and generating a signal indicating the left and right directions. By moving the image of the object relative to the left and right and displaying it, you can perform training while playing a video game. Can.

However, the running device described in Patent Document 1 does not increase or decrease the load on the user in accordance with the image of the traveling course, and has a problem that training corresponding to the actual traveling course cannot be performed.

Further, in the running device described in Patent Document 2, if the image of the running route is a slope, the inclination angle is displayed on the auxiliary screen on the CRT display in an analog manner, and the running means is inclined according to the displayed angle. The angle is changed to increase or decrease the load on the user, but it is not an image of the actual driving course, and the angle displayed on the auxiliary screen corresponds to the actual driving course, The problem that the training corresponding to the actual traveling course cannot be performed has not been solved.

Accordingly, an object of the present invention is to provide an image for a virtual running system, which can be acquired with a simple configuration, in which the captured image of the traveling course and the signal related to the measured inclination of the traveling course are accurately synchronized, and To provide a gradient signal acquisition device.

Another object of the present invention is to faithfully correspond to the actual driving course from the video of the driving course acquired by the video and the gradient signal acquisition device and the signal relating to the inclination state of the driving course acquired and stored in synchronization therewith. It is to provide a virtual running system that can perform training.

According to the present invention, a video and gradient signal acquisition device for a virtual running system has an analog audio input terminal and a storage means, and an imaging means for capturing a video of a traveling course to obtain a digital video signal, and a traveling course A tilt sensor that detects an inclination state of the image sensor simultaneously with photographing by the photographing means and outputs an analog gradient signal, a signal processing means that converts the analog gradient signal output from the tilt sensor into a digital serial signal, and a digital signal from the signal processing means Level conversion means for level-converting and outputting the serial signal. The imaging means is configured to further digitally convert the digital serial signal input from the level conversion means via the analog audio input terminal, and store it in the storage means in synchronization with the digital video signal.

By converting the analog gradient signal from the tilt sensor when shooting the traveling course into a digital serial signal, and converting the level to the analog voice input terminal of the shooting means, this digital serial signal is recognized as an analog signal, Stored in synchronization with the digital video signal. For this reason, the image | video of the image | photographed driving | running | working course and the signal regarding the inclination condition of the measured driving | running | working course can be acquired in the state which synchronized exactly.

It is preferable that the photographing means and the inclination sensor are installed on the same moving body that moves at a predetermined speed along the traveling course. Thereby, the video signal corresponding to the actual traveling course and the gradient signal of the traveling course can be obtained.

It is preferable that the level converting means is an optical isolation means such as a photocoupler. Thereby, not only the level conversion of the digital signal can be easily performed, but also the separation of the signal is performed, so that mixing of noises and the like can be prevented.

It is also preferable that the storage means is an internal memory or an external memory of the photographing means. If the external memory is used, the video signal corresponding to the traveling course and the gradient signal of the traveling course can be taken out to the outside as they are. Even in the case of the internal memory, if the stored data is copied to the external memory, it can be similarly taken out.

According to the present invention, the virtual running system reads the running means on which the user can run on the running belt and the digital video signal acquired by the above-described video and gradient signal acquisition device from the storage means, and runs on the running belt. Display means for displaying to the user, and inclination angle control means capable of controlling the inclination angle of the running belt of the running means. The inclination angle control means reads the digital serial signal stored in the storage means so that the image on the display means and the inclination angle of the running belt are synchronized, and controls the inclination angle of the running belt according to the read digital serial signal. .

By using such a virtual running system, the inclination angle of the traveling belt is accurately controlled according to the image of the photographed traveling course and the inclination of the traveling course synchronized therewith, so that the actual traveling course (for example, A more realistic training that faithfully corresponds to roads, parks, fields, wilderness fields, coasts, mountain trails, etc.).

According to the present invention, it is possible to obtain a captured image of a traveling course and a signal related to the measured inclination of the traveling course in a precisely synchronized state, and more realistically correspond to an actual traveling course. Training is possible.
