About Riegl technology

NEW TECHNOLOGY

In RIEGL’s V-Series devices, digital processing of return signal allows separation of up to 16 - ∞ measuring points from measuring pulse in real-time instead of earlier one point.

In RIEGL’s digitized Q Series aerial laser scanners pulse is stored as a whole, allowing separation of unlimited measurement points from a single pulse in post-processing.

WHAT IS MULTI-POINT LASER?

Multi-point laser is based on pulse laser (Time of Flight), ie the pulse’s round-trip time measurement. Multi-point technique (Online Waveform Analysis) return signal is digitized, making it possible to separate a number of echoes. If the measuring pulse meets planar surfaces sized at least the size of beams entire cross-section, the surface creates one echo. Shape of the echo depends on the material, color and softness of the material. When measuring pulse hits partially different surfaces, the returning echo’s shape is indefinite or consists of several, different shaped, echoes separable from each other.

REAL-TIME INTERPRETATION OF MEASURING PULSE

Digitizing the entire return signal allows separation of echoes from each other. Each partial echo is compared to the echo library, when the echoes of various shapes can be interpreted mathematically by calculating with different formulas. At the same time the calculated points can be classified by measuring order as well as by quality.

What are the advantages of multi-point laser?

When comparing multi-point laser technology to the normal pulse lasers, the biggest advantages consist of: measuring accuracy, possibility of measuring on covered area and the possibility of classification of measured points to speed up processing (editing) of data.

Measurement accuracy is improved, because measurement points from different materials can now be calculated using each materials return pulse’s specific form.

In a sense, obstructed areas can also be found when measuring interior spaces and piping. Some of the measuring pulses reaches the edge of the column or tube, some continue to the next surface. The same measurement pulse can "touch" many surfaces until it is completely reflected back. In Point Clouds appears "air points" and “point showers” at the edges of poles and pipes which makes editing of data difficult. In multi-point technique, the above-mentioned points hardly present, but different points are formed o each "touched" surface. In addition, the classification of measured points enables automatic editing.

When measuring outside, grasses, shrubs, tree branches, etc. prevents a complete penetration of the beam to the actual desired measurement surface. In this case the calculated measurement point is not on desired surface, but lies somewhere in between the first and last contacted surfaces. In multi-point technique on covered surface different contact surfaces are created as own classified outlets, which also creates classified point to the desired surface.
