Abstract
In one aspect, there is provided a system including at least one processor, and at least one memory including program code which when executed by the at least one processor causes operations including capturing an image of at least a portion of a surface of an object; generating, from the captured image, pixel intensity data; in response to generating the pixel intensity data, determining, based on a height error model, height error data, wherein the height error data indicates an uncertainty of at least one height measurement of the object; and determining, based on the height error data, whether the object satisfies a threshold criteria for acceptance of the object. Related system, methods, and articles of manufacture are also disclosed.
Claims19
A system comprising:
- at least one processor;
- and
- at least one memory including program code which when executed by the at least one processor causes operations comprising:
- capturing an image of at least a portion of a surface of an object;
- generating, from the captured image, pixel intensity data;
- in response to generating the pixel intensity data, determining, based on a height error model, at least one height measurement of the object and height error data, wherein the height error data indicates an uncertainty of the at least one height measurement of the object;
- and
- determining, based on the height error data, whether the object satisfies a threshold criteria for acceptance of the object, wherein determining whether the object satisfies the threshold criteria further comprises determining whether the object satisfies a threshold height.
A method comprising:
- capturing an image of at least a portion of a surface of an object;
- generating, from the captured image, pixel intensity data;
- in response to generating the pixel intensity data, determining, based on a height error model, at least one height measurement of the object and height error data height error data, wherein the height error data indicates an uncertainty of the at least one height measurement of the object;
- and
- determining, based on the height error data, whether the object satisfies a threshold criteria for acceptance of the object, wherein determining whether the object satisfies the threshold criteria further comprises determining whether the object satisfies a threshold height.
A non-transitory computer-readable storage medium including program code, which when executed by at least one processor, causes operations comprising:
- capturing an image of at least a portion of a surface of an object;
- generating, from the captured image, pixel intensity data;
- in response to generating the pixel intensity data, determining, based on a height error model, at least one height measurement of the object and height error data, wherein the height error data indicates an uncertainty of at least one height measurement of the object;
- and
- determining, based on the height error data, whether the object satisfies a threshold criteria for acceptance of the object, wherein determining whether the object satisfies the threshold criteria further comprises determining whether the object satisfies a threshold height.
