Problems solved by technology
On the one hand, this is due to the limited frequency or pulse rate of the electromagnetic radiation (especially laser pulses) emitted by existing transmitters into the measurement area
On the other hand, the speed of movement of the emitter and / or the emitted beam for recording the distance profile in existing scanning devices over the scanning angle is limited due to their construction, especially in relation to mechanical loads

Embodiment Construction
[0060] The invention relates to a device and a method for recording a distance profile with a plurality of distance pixels. The device comprises a plurality of emitters arranged as an array of emitters for transmitting electromagnetic radiation to the measurement area; at least one receiving unit for detecting radiation reflected by the measurement area; the distance of the object of the emitted radiation, each distance forming a distance pixel; and the deflection unit, which deflects the emitted radiation to the scanning direction within the scanning angle range, so that each distance profile is continuously generated in the Distance image points of a plurality of scanning patterns displaced sequentially in the scanning direction, each scanning pattern is an image formed by the emitter array, and at least several distance image points in each scanning pattern are in the scanning direction spaced apart from each other.

The present invention provides a device for recording range profiles, wherein each range profile has a plurality of range pixels. The device comprises: a plurality of emitters arranged as an array of emitters, transmitting electromagnetic radiation to the measurement area; at least one receiving unit for detecting radiation reflected by the measurement area; distances of the irradiated object, each distance forming a distance pixel; and a deflection unit, which deflects the emitted radiation into the scanning direction within the range of scanning angles, so that for each distance profile is continuously generated in the scanning direction The distance pixels of a plurality of scanning patterns offset sequentially, each scanning pattern is an image formed by the emitter array, and at least several distance pixels in each scanning pattern are spaced from each other in the scanning direction. The invention also provides a method for recording the distance profile and an operation method for self-checking of the distance profile recording device.
Description
technical field [0001] The invention relates to a device and method for measuring objects. Background technique [0002] The distance profile can be determined eg by detecting the object optically, using electromagnetic radiation having wavelengths of visible or invisible light. Its purpose consists in optically scanning the surface of the corresponding object at discrete measurement points and on the basis of this inferring the geometric state of the object, in particular the size of the object or even the type of object. Thus, by locating points on the surface of the object the corresponding object can be scanned. For example, by a laser method, and measuring the round-trip time of flight (TOF) of a laser beam from a device to a distance image point of an object. [0003] Existing so-called line scanners comprise a pulsed laser source whose laser pulses are repeatedly deflected by a rotating mirror for scanning, thereby continuously determining a plurality of range image...
