Abstract: An image measuring apparatus includes: a CAD data storage unit that stores CAD data of at least one object and CAD data information including designed dimensions extracted from the CAD data, measurement points corresponding to the design dimensions, and edge detection tool conditions used to detect the edges of the measurement points in advance for each different CAD data; a CAD data retrieval unit that retrieves CAD data from the CAD data storage unit that are similar in shape to the measurement object represented in the captured image; a CAD data setting unit that performs best-fit of the CAD data identified based on the retrieval to the image of the measurement object as the CAD data of the measurement object, and sets the coordinate system of the CAD data; and a measurement performing unit that performs edge detection and dimensional measurement for each measurement point using the CAD data information.

Abstract: An image measuring apparatus and a program with good operability even when the information display screen is small or the operator's skill level is low is provided. An image measuring apparatus according to the present invention captures an image of a measurement object and measures the dimensions of the measurement object through a plurality of operation steps. The image measuring apparatus comprises: a display unit that displays user interfaces that accept inputs through input operations by an operator; a process control unit that causes the display unit to display only the user interfaces that accept the inputs necessary to use the available functions in each of the operation steps; and a function execution unit that executes the function for which the input related to use is made on the user interface.

Abstract: An image measuring apparatus includes: a mounting table on which a measurement object is placed; an image capturing unit disposed opposite the mounting table and captures an image of the measurement object; a control unit that controls the image measuring apparatus; and a memory unit that stores at least the shape of the measurement object and the measurement method corresponding to the measurement object, associated to each other. The control unit includes: a placement judging unit that judges whether or not the measurement object is placed on the mounting table in a state ready for measurement based on the image captured by the image capturing unit; and a measurement performing unit that selects a measurement method based on the shape of the measurement object appearing in the image and performs the measurement, when the placement judging unit determines that the measurement object is ready for measurement.

Abstract: A method for eliminating lens flare that eliminates lens flare is provided. The lens flare elimination method performs: a step for acquiring images by irradiating the coaxial episcopic illumination light with varying irradiation intensities and capturing images at each irradiation intensity while the object is not placed on the mounting table; a step for capturing an image of the object by irradiating the object placed on the mounting table with the coaxial episcopic illumination light at an arbitrary irradiation intensity; a step for estimating an image for correction, which is the image at the irradiation intensity irradiated when the measurement object is captured, based on the images acquired in the image acquiring step; and a step for generating a post-correction image in which the lens flare is eliminated from the image of the object by obtaining the difference between the image of the object and the image for correction.

Abstract: An image measuring apparatus, according to the present invention, captures an image of the measurement object and measures the dimensions of the measurement point of the measurement object by analyzing the image. The image measuring apparatus comprises: a display unit that displays the image of the measurement object; an input unit that accepts input of the trajectory traced by an operator on the image displayed on the display unit; an edge detection unit that detects an edge based on the traced trajectory on the image; and a measurement performing unit that performs measurement based on one or more detected edges.
