METHOD AND DEVICE FOR VISUALLY SUPPORTED CLIMBING

The invention relates to a method for visually assisted climbing.

Furthermore, the invention relates to a device for visually assisted climbing.

Finally, the invention relates to a use of such a device.

Methods for visually assisted climbing on climbing walls are known from the prior art. These known methods work on the principle that handles or steps are marked optically on a climbing wall. Associated handles or kicks are z. B. marked with ascending numbers or labeled piece of paper, which are attached either self-adhesive or with various fasteners on the climbing wall. This will set a climbing route. It can be provided that all handles or steps, which are marked with a piece of the same color, form a climbing route. However, processes of this type have the disadvantage that, in particular, self-adhesive labels can be lost very easily and thus have to be replaced again and again. Next, the numbers or notes usually have to be replaced again and again when implementing a climbing route, which is time consuming. Another disadvantage is the fact that the label on such tools usually can not turn out large and thus they are readable only from a short distance.

From the prior art it is also known to colorize handles a climbing route in a particular color. It is common on climbing walls to change the sequence of handles to be climbed from time to time to maintain or increase the attractiveness of the climbing wall to the users. However, this has the disadvantage that when the route is changed, the color of the handles no longer matches a new configuration of the climbing route. Thus, handles must be replaced solely because of the color. However, this is relatively expensive and time-consuming because of the attachment of the handles on the climbing wall by screws.

The object of the invention is to provide a method and an apparatus of the type mentioned above, with which climbing routes resistant and at the same time can be specified variably and universally applicable.

This object is achieved in that in a method of the type mentioned a climbing route, especially handles and / or steps, on a surface, preferably a climbing wall, is marked with light from a light source.

An advantage of the method according to the invention is to be seen in particular that can be done easily and quickly by marking with light a light source changing the climbing route. Also, there are no parts that can be lost.

Conveniently, the light is emitted by a projector. In particular, a laser projector may be provided as the projector which emits less laser light but emits sufficient intensity for a route marking. In this case, the climbing route can in particular be marked by a side opposite the surface or climbing wall. Furthermore, with the light of a projector even non-flat surfaces can be easily and easily recognized. If a laser projector is used, there is also the advantage that in comparison with a conventional projector a much larger angular range of about ± 40 ° and thus a large area can be painted or larger parts of a climbing wall can be operated. It is useful that the surface is detected by an optical detection unit in order to be able to continuously determine a position of a climbing person by means of subsequent image evaluation.

Further, it is advantageous that in a step, several points on the surface are marked with the light of the light source and in a further step, the marked points are detected by the optical detection unit and then an adjustment of the coordinates of the light source and the coordinates the optical detection unit, in particular computer supported AT 13 918 Ul 2014-12-15 is executed. This makes it possible, even before climbing the detected surface or climbing wall on the one hand and the light source on the other hand to match. The light source and the detection unit are usually positioned opposite to different positions of the surface or climbing wall and therefore have a different field of view. By matching or transformation of one coordinate system into the other, a calculated coincidence of the fields of view is achieved, so that images captured by the detection unit and light emitted by the light source onto the surface are matched to one another.

The corresponding calibration or adjustment needs to be performed only once for each surface or climbing wall. Once the coordinate systems have been adjusted, the light source can be used to specify any climbing route. If a climbing person is being tracked by the detection unit at the same time, the climbing route can be adapted exactly to the climbing rhythm. For an automated adjustment, it is expedient that a computing unit connects the detection unit and the light source, wherein the arithmetic unit may be an integral part of the detection unit or the light source.

The calibration can be done by various methods. For rapid, but also sufficiently accurate calibration, it is expedient if the area recorded by the detection unit is segmented into essentially planar partial surfaces. Light from the light source is radiated into individual subareas, so that the coordinate systems of acquisition unit and light source can be calibrated by coordinate transformation. By subdividing the surface or climbing wall into essentially planar sections, it is also possible, in particular, to achieve an adjustment in the case of curved surfaces.

Furthermore, it is possible for a calibration that a body climbing on the surface is detected by the optical detection unit and the climbing route is marked on the basis of a detected position. This is an optimal, timed route preset possible. In addition, a continuation of a climbing route can be changed at any time or adapted individually to the ability of a climbing person.

Here it is favorable for a coordinated route specification, when the climbing body is detected substantially simultaneously with the marking of the handles and / or kicks.

This allows climbing without interruptions or without waiting for the next to be marked handles.

Although it is not mandatory, but it can be advantageously provided that an outline of the detected climbing body is projected onto the surface with the light of the light source. As a result, a climber can quickly take a set position shown by light without external help.

The method according to the invention also makes it possible for the climbing route, in particular the handles and / or steps, to be marked on the surface simultaneously and / or sequentially with the light of the light source. As a result not only several handles can be marked at the same time, but also lines can be displayed within which climbing is allowed.

It has been proven that the climbing route to be marked is selected on a connection unit. For this purpose, the connection unit expediently communicates directly or indirectly with a computing unit which communicates with the light source and / or the detection unit. This makes it possible to select professional climbing routes, to set your own climbing routes or to customize a given climbing route.

The further object of the invention is achieved by a device of the type mentioned above, wherein an optical detection unit detects a surface, preferably a climbing wall, and a body climbing on the surface for determining its position and light of a light source, depending on the specific position , a climbing route marked on the area.

An advantage of a device according to the invention is to be seen in particular in that an optical detection unit detects an area, preferably a climbing wall, and a body climbing on the surface for position determination thereof and light a light source, depending on the specific position, a climbing route marked on the surface. Such a device allows for marking a climbing route and picking it up and the climbing body in timed relation.

The coordinates of the optical detection unit and the coordinates of the light source are computer-assisted adjusted so that they can communicate without time delay. For this purpose, an arithmetic unit may be provided which is directly or indirectly connected to the detection unit and the light source.

A further advantage results when a connection unit connects the light source and the optical detection unit and thus the data acquired by the optical detection unit can be analyzed. It is possible that the above-mentioned arithmetic unit simultaneously represents the connection unit.

It is also favorable if the light source is a projector, in particular a laser projector. With a laser projector climbing routes can be illuminated even on curved climbing walls evenly and without large differences in light intensity, so that there is always an even route marking along a climbing route for a climbing person.

For the connection unit z. B. be provided a tablet PC. This can be connected via Wi-Fi, so that the selection of a climbing route with simultaneous visit of the climbing wall can be made from different perspectives.

A use of the device according to the invention is typically carried out when recording and analyzing climbing movements and when climbing the marked climbing routes, especially handles and / or kicks and when taking projected climbing positions on a surface, preferably a climbing wall.

Further features, advantages and effects of the invention will become apparent from the illustrated embodiment. In the drawings, to which reference is made, Figure 1 shows a device for visually assisted climbing; Fig. 2 is a schematic representation for the adjustment of the coordinates of the optical

Detection unit and the coordinates of the light source.

In Fig. 1, a device 1 for visually assisted climbing on a surface 3, preferably a climbing wall, a light source 5 and an optical detection unit 6 is shown. Light 4 of the light source 5, marked a climbing route, in particular handles and / or steps 2. If the light source 5 is designed as a projector, this can not only climb routes on a flat surface, but also climbing routes on structured, a rock modeled, three-dimensional climbing walls evenly , In particular, a laser projector can be provided. The optical detection unit 6 detects both the surface 3 and the positions of the handles and / or kicks 2 and optionally a climbing person.

If the device 1 used in a new climbing gym with a previously unknown climbing wall, points 7, 8 are marked on the surface 3 with the light 4 of the light source 5 and in a second step, the marked points 7, 8 in a first step detected by the optical detection unit 6. Subsequently, an adjustment of the coordinates of the light source 5 and the coordinates of the optical detection unit 6 computer-aided with a computing unit 10 is performed. For this purpose, the arithmetic unit is connected to both the detection unit 6 and the light source 5. In Fig. 2 this balance is shown schematically. The detection unit 6 and the light source 5 are arranged at different positions of the climbing wall opposite stationary. The field of view of detection unit 6 and light source 5 are therefore different. This means that the points 7, 8 are not located at the same position in the different coordinate systems of the detection unit 6 and the light source 5. By a corresponding algorithm of the arithmetic unit 10, the two coordinate systems are aligned or transformed into a single coordinate system, so that the points 7, 8 are brought to coincidence. For a suitable adjustment, a Hough transformation can be used, so that even with curved climbing walls a sufficiently accurate adjustment is possible. The adjustment is a one-time calibration or tuning of the detection unit 6 and the light source 5. If the coordinate systems adjusted, any climbing route can be specified in the sequence, with the detection unit 6 a climbing person is detected and the light source. 5 depending on a current position of the climbing person the further route and / or target positions are marked.

The light 4 of the light source 5 can mark both several handles and / or steps 2 simultaneously as well as individual handles and / or steps 2 or more handles and / or steps 2 sequentially. As a result, several variants for climbing are specified. Also, areas may be specified by lines 4 marked by the light on the area 3 within which it is permitted to climb. A connection unit 9 serves to select the climbing route to be marked. Individual handles and / or kicks 2 can be selected and changed on this at any time and without delay. A climber can put together on the connection unit 9 a climbing route of various grips and / or kicks 2 or also of lines. Furthermore, climbing processes of climbing bodies detected on the connection unit 9 are analyzed and stored. Also climbing routes can be stored on the connection unit 9 and retrieved at any time. If a climbing body is located on the surface 3, this is also detected by the optical detection unit 6, and based on the detected position, the further climbing route is marked by the light 4 of the light source 5. This detection is possible as far as possible simultaneously with the marking of the climbing route, in particular of the handles and / or steps 2. In one variant, an outline of the detected body with the light 4 of the light source 5 can be projected onto the surface 3.

The connection unit 9 is usually in communication with the arithmetic unit 10, in particular via a radio link. If the connection unit 9 is transportable, a climbing person can define a route on the connection unit 9 and at the same time view the climbing wall from different perspectives. But it is also possible that the connection unit 9 simultaneously represents the arithmetic unit 10.

The device 1 as explained above can be used for a long time stationary in a leisure facility. In principle, however, the device 1 is mobile, since the projector 5, the detection unit 6, the arithmetic unit 10 and the possibly provided connection unit 9 can be designed to be small and lightweight. Due to the ease of transport of the device 1, it is possible to use this z. For example, in the context of a brief event such as a company excursion by a supervisor in front of a natural rock face, make the calibration within a few minutes and then start climbing.

Although a projector is preferred, a mark can also be made by a plurality of lamps such as LED lights, which are arranged on the surface 3, for example in the handles and / or treads 2. In this case, the lamps are driven by the arithmetic unit 10, which in turn is connected to the detection unit 6. Calibration is unnecessary in this case. 4.7
