Measurement apparatus and sorter

A measurement apparatus for measuring a feature about shape and/or dimension with respect to a whole and/or part of a target, the measurement apparatus comprising:

• a conveyance part configured to convey the target;
• an electromagnetic wave irradiation source configured to irradiate the target with an electromagnetic wave while the target is conveyed due to an action of the conveyance part;
• a line sensor including a plurality of electromagnetic wave detection elements linearly arranged in a first direction intersecting with a conveyance direction of the target, the line sensor being configured to detect at least one of a reflected electromagnetic wave emitted from the electromagnetic wave irradiation source and reflected on the target and a transmitted electromagnetic wave emitted from the electromagnetic wave irradiation source and transmitted through the target;
• and
• a controller,
• the controller is configured to:
• detect a conveyance velocity in a predetermined direction with respect to the target in transit;
• and
• determine the feature of the target based on an image acquired by the line sensor and the conveyance velocity in the predetermined direction.
