Abstract
A calibration parameter generating system and method are provided. The system receives calibration image frames from image capturing devices, each of the calibration image frames at least includes a feature sub-pattern on at least one curved surface corresponding to a calibration object, and the feature sub-pattern is a part of at least one feature pattern. The system generates a calibration parameter of each of the image capturing devices based on the feature sub-pattern of each of the calibration image frames.
Claims20
A calibration parameter generating system, comprising:
- a calibration object, wherein the calibration object comprises at least one curved surface, and each of the at least one curved surface comprises at least one feature pattern;
- a plurality of image capturing devices;
- and
- a processing device, being communicatively connected to the plurality of image capturing devices, and being configured to perform operations comprising:
- receiving a plurality of calibration image frames from the plurality of image capturing devices, wherein each of the calibration image frames at least comprises a feature sub-pattern on the at least one curved surface corresponding to a calibration object, the at least one curved surface of the calibration object provides a recognizable viewing angle of 360 degrees, and the feature sub-pattern is a part of the at least one feature pattern;
- and
- generating a calibration parameter of each of the image capturing devices based on the feature sub-pattern of each of the calibration image frames.
