Abstract
An image measuring apparatus includes: an image acquiring section which images an object to generate input image data; an image processing section which performs image processing on the input image data to generate two output image data; a display which displays display image data corresponding to one of the output image data generated by the image processing section for an input of at least one measurement point; an input unit which inputs a measurement operation on the display image data as a reference; and a measurement section which performs measurement based on another output image data for which image processing by the image acquiring section is different from that for the display image data based on the measurement operation on the input unit.
Claims8
An image measuring apparatus comprising:
- an image acquiring section which includes an optical system for stereo measurement having two object lenses that are disposed so as to be spaced apart from each other, images an object, and generates input image data for one-frame including a pair of parallax images acquired by the two object lenses;
- a processing selection section that automatically selects a brightness gradation converting processing which satisfies a predetermined measurement accuracy condition among a plurality of the brightness gradation converting processing and sets the selected brightness gradation processing to a first brightness gradation converting processing;
- an image processing section which performs the first brightness gradation converting processing selected by the processing selection section to the input image data and generates output image data including the pair of the parallax images for a measurement operation and which performs a second brightness gradation converting processing that is different from the first brightness gradation converting processing to the input image data and generates output image data including the pair of the parallax images for a display;
- an input unit which performs an operation input to measure the object to be imaged for a measurement operation displayed on the display;
- and
- a measurement section which performs measurement of the object based on the operation input of the input unit to the output image data for a measurement operation generated by the image processing section;
- another of the first and second output image data for which image processing by the image processing section is different from that for the display image data based on the measurement operation on the input unit;
- and wherein
- the image measuring apparatus is configured such that the image processing operation does not change a parallax of the first output image data and of the second output image data.
