  • Publication number: 20090180708
    Abstract: An image measuring instrument includes a camera that images a plurality of measured points based on a preset measuring procedure, and an illumination unit that irradiates the measured points. The image measuring instrument measures a dimension and a shape of a to-be-measured object while the illumination unit irradiates light having illumination light quantity corresponding to an illumination preset value with reference to the illumination preset value that is preliminarily set for every measured point. An illumination light quantity setting method includes a command signal output step that outputs a command signal for irradiating light having the illumination light quantity corresponding to the illumination preset value for every measured point, an offset value assigning step that assigns an offset value to the command signal to be sent to the illumination unit, and a setting step that sets the offset value to be variable.

  • Patent number: 7268894
    Abstract: An image measuring method comprises making no stop of an imaging means relative to a measurement stage at measurement positions (MP1-MP3), and capturing instantaneous images to acquire information required for measurement. A first direction to a measurement position (MP1) to be measured next and a second direction from the measurement position (MP1) to a next measurement position (MP2) form an angle therebetween. If this angle exceeds a certain angle, an overshoot path is formed at a location beyond the measurement position (MP1) in the first direction. The larger the angle formed between the first direction and the second direction, the lower the measurement speed at the measurement position (MP1) is made.

  • Patent number: 7231726
    Abstract: A cover body (100), formed of an elastic member for covering a slider body (510) of a caliper, is provided with concavities and convexities (112) on the inner surface thereof and concavities and convexities (103) on the outer surface thereof. The cover body (100) is arranged so that it is easily deformed elastically in the portion of the concavities and convexities. When a shock is given from the outside, the portion of the concavities and convexities is deformed elastically to absorb the shock, hence the shock given to the slider body (510) is reduced. Accordingly, damage or failure hardly occurs on the measuring instrument.

  • Patent number: 7152020
    Abstract: A mobile communications terminal having a communicator for transmitting and receiving a signal to/from a base station is connected to a measuring instrument through wireless medium and a cable. A control processing software stored in a memory of the mobile communications terminal is executed. The mobile communications terminal converts the measurement data acquired by measurement of the measuring instrument into the same format as the signal transmitted to and received from the base station and the converted measurement data is read into a controller to store in a storage. The measurement data is transmitted from the communicator to the base station to be stored in a data storage and published on a web site in a manner that a third party can check.

  • Publication number: 20060274330
    Abstract: Within a prioritized mode selection dialog, either a measurement accuracy prioritized mode or a measurement speed prioritized mode is selected. If the measurement accuracy prioritized mode is selected, then processing for entering a tolerable amount of movement is executed. Then, a relative movement speed of a CCD camera to a measurement stage is calculated from the entered amount of movement. Finally, image information is captured at a lower speed than the calculated relative movement speed to execute image measurement. If the measurement speed prioritized mode is selected, then processing for entering a relative movement speed is executed, and image information is captured at the entered relative movement speed to execute image measurement.
