Abstract
The present technology is directed to determining an accuracy of an infrared (IR) camera, and more particularly, validating a distortion accuracy of an IR camera. The present technology can receive one or more images of a calibration harp captured by the IR camera, wherein the one or more images include a plurality of lines corresponding to a plurality of strings of the calibration harp. The present technology can further determine a degree of distortion of the plurality of lines based on a distortion error coefficient, wherein the distortion error coefficient is computed based on edge points of the plurality of lines on the one or more images.
Claims20
A method for determining an accuracy of an infrared (IR) camera, the method comprising:
- receiving one or more images of a calibration harp captured by the IR camera, wherein the one or more images include a plurality of lines corresponding to a plurality of strings of the calibration harp;
- and
- determining a degree of a distortion of the plurality of lines based on a distortion error coefficient, wherein the distortion error coefficient is computed based on edge points of the plurality of lines on the one or more images.
A system for determining an accuracy of an infrared (IR) camera, comprising:
- a storage configured to store instructions;
- a processor configured to execute the instructions and cause the processor to:
- receive one or more images of a calibration harp captured by the IR camera, wherein the one or more images include a plurality of lines corresponding to a plurality of strings of the calibration harp, and
- determine a degree of a distortion of the plurality of lines based on a distortion error coefficient, wherein the distortion error coefficient is computed based on edge points of the plurality of lines on the one or more images.
A non-transitory computer readable medium comprising instructions, the instructions, when executed by a computing system, cause the computing system to:
- receive one or more images of a calibration harp captured by an infrared (IR) camera, wherein the one or more images include a plurality of lines corresponding to a plurality of strings of the calibration harp;
- and
- determine a degree of a distortion of the plurality of lines based on a distortion error coefficient, wherein the distortion error coefficient is computed based on edge points of the plurality of lines on the one or more images.
