Abstract
A method and device for contactless measurement of a temperature, in particular pyrometer, preferably 1-point pyrometer. The measuring device (1) has a camera (4) for recording an image (7′) of an environment (7) of a measurement spot (9) and a processor for ascertaining and outputting, in particular displaying, a location of the measurement spot in the image. For the temperature measurement, an environment (7) of a measurement spot (9) is recorded as an image and a location of the measurement spot (9) in the environment (7) is calculated and output in the image (7′).
Claims9
A method for contactless measurement of a temperature, the method comprising:
- recording an environment (7) of a measurement spot (9) as an image;
- calculating and outputting a location of the measurement spot (9) in the environment (7) in the image (7′);
- including determining a distance to the measurement spot (9);
- calculating a diameter of the measurement spot (9) on a measurement object (8) from the distance and a known divergence of the measurement spot (9);
- outputting the measurement spot (9) as a virtual measurement spot (9′) with the calculated diameter in the image (7′);
- generating a measurement log automatically, wherein the measurement log contains a measurement result of the temperature measurement, an image (7′) of the measurement object, the measurement spot, and a recording time;
- and
- automatically saving and/or transmitting the measurement log to an evaluation unit.
A measuring device (1) for contactless measurement of a temperature, the measuring device comprising:
- a camera (4) for recording an image (7′) of an environment (7) of a measurement spot (9);
- means for determining a distance to the measurement spot (9), and
- a processor configured for calculating a diameter of the measurement spot (9) on a measurement object (8) from the distance and a known divergence of the measurement spot (9), and ascertaining and outputting a location of the measurement spot in the image, wherein the measurement spot (9) is output as a virtual measurement spot (9′) with the calculated diameter;
- the processor is further configured for automatically generating a measurement log, wherein the measurement log contains a measurement result of the temperature measurement, an image (7′) of the measurement object, the measurement spot and a recording time;
- and
- means for storing the measurement log and/or transmitting the measurement log to an evaluation unit.
