Erfindungsgemäß umfasst der Laserscanner (1) eine zumindest bereichsweise kugelförmig ausgebildete und zumindest den Sender (2) überdeckende Abdeckung (4) mit steuerbaren Klappen (5), wobei an Innenflächen der Klappen (5) Spiegel (6) zu einer Umlenkung der Laserstrahlen (L) an eine Innenfläche der Abdeckung (4) angeordnet sind und Winkel der Spiegel (6) derart ausgebildet sind, eintreffende Laserstrahlen (L) zu reflektieren, bis diese durch eine geöffnete Klappe (5) aus einem zwischen der Abdeckung (4) und zumindest dem Sender (2) angeordneten Innenraum (I) austreten.The invention relates to a laser scanner (1) for detecting a vehicle environment (F) with at least one transmitter (2) for emitting laser beams (L). According to the invention, the laser scanner (1) comprises a cover (4) with controllable flaps (5) that is at least partially spherical and covers at least the transmitter (2), with mirrors (6) on the inner surfaces of the flaps (5) for deflecting the laser beams (L ) are arranged on an inner surface of the cover (4) and angles of the mirrors (6) are designed to reflect incident laser beams (L) until they are opened by an open flap (5) from between the cover (4) and at least that Exit the transmitter (2) located inside (I).
Description
Die Erfindung betrifft einen Laserscanner zur Erfassung einer Fahrzeugumgebung gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a laser scanner for detecting a vehicle environment according to the preamble of claim 1.
Aus der
Der Erfindung liegt die Aufgabe zu Grunde, einen verbesserten Laserscanner zur Erfassung einer Fahrzeugumgebung anzugeben.The invention is based on the object of specifying an improved laser scanner for detecting a vehicle environment.
Die Aufgabe wird erfindungsgemäß mit einem Laserscanner gelöst, welcher die im Anspruch 1 angegebenen Merkmale aufweist.The object is achieved with a laser scanner which has the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Ein Laserscanner zur Erfassung einer Fahrzeugumgebung, umfassend zumindest einen Sender zur Aussendung von Laserstrahlen. Weiterhin umfasst der Laserscanner erfindungsgemäß eine zumindest bereichsweise kugelförmig ausgebildete und zumindest den Sender überdeckende Abdeckung mit steuerbaren Klappen, wobei an Innenflächen der Klappen Spiegel zu einer Umlenkung der Laserstrahlen an eine Innenfläche der Abdeckung angeordnet sind und Winkel der Spiegel derart ausgebildet sind, eintreffende Laserstrahlen zu reflektieren, bis diese durch eine geöffnete Klappe aus einem zwischen der Abdeckung und zumindest dem Sender angeordneten Innenraum austreten.A laser scanner for detecting a vehicle environment, comprising at least one transmitter for emitting laser beams. Furthermore, according to the invention, the laser scanner comprises a cover with controllable flaps, which is at least partially spherical and covers at least the transmitter, mirrors being arranged on the inner surfaces of the flaps for deflecting the laser beams to an inner surface of the cover and angles of the mirrors being designed to reflect incoming laser beams until they emerge through an open flap from an interior arranged between the cover and at least the transmitter.
Der Laserscanner führt zu dem Vorteil, dass auf eine Verwendung eines rotierenden Elements, insbesondere eines Rotors, zur Verteilung von Laserstrahlen des Laserscanners verzichtet werden kann, ohne dass dabei eine Sendeleistung und folglich eine Reichweite des Laserscanners reduziert werden. Weiterhin reduziert sich eine erforderliche Energie zum Betrieb des Laserscanners aufgrund eines Verzichts des rotierenden Elements, wobei eine Reichweite des Laserscanners in besonders vorteilhafter Weise genauso groß ist wie die bekannter Laserscanner mit einem rotierenden Element.The advantage of the laser scanner is that it is not necessary to use a rotating element, in particular a rotor, for distributing laser beams from the laser scanner, without reducing the transmission power and consequently the range of the laser scanner. Furthermore, the energy required to operate the laser scanner is reduced due to the omission of the rotating element, the range of the laser scanner in a particularly advantageous manner being the same as that of the known laser scanner with a rotating element.
Des Weiteren führt der Aufbau des Laserscanners zu dem Vorteil, dass eine Überhitzung des Laserscanners dadurch vermieden werden kann, dass am Ende einer Umlenkkette eines Laserstrahls zumindest immer eine Öffnung ist, selbst wenn eine Klappensteuerung des Laserscanners defekt sein sollte.Furthermore, the construction of the laser scanner has the advantage that overheating of the laser scanner can be avoided by at least always having an opening at the end of a deflection chain of a laser beam, even if a flap control of the laser scanner should be defective.
