An experimental machine part sorting system by the device is also described. The real\u2010time range measurement is performed as follows. The laser slit\u2010ray is projected on the object, scanning its surface with a high speed. In the meantime, the range to each point on the object surface is determined by triangulation. The operations are executed by a dedicated hardware. The experimental device is composed of a slit\u2010ray projecting unit, a slit\u2010ray scanning control unit, a TV camera for the imaging of the ray reflected from the object and the signal processing unit, which calculates the range and the shape of the object. The performance of the device is such that the range to the object and its shape, located in the range of 60 cm \u00d7 60 cm at the distance of 100 cm are determined for 48 points (<jats:italic>x<\/jats:italic>\u2010direction) \u00d7 50 points (z\u2010direction) in 490 ms. The accuracy of the range measurement is \u00b13.0 percent in the above condition. An experimental sorting system of machine parts has been developed using this method. By applying a new range gating method to this device, the sorting of three\u2010dimensional machine parts was realized in realtime by a simple algorithm, indicating the effectiveness of the proposed method and the device.<\/jats:p>","DOI":"10.1002\/scj.4690170310","type":"journal-article","created":{"date-parts":[[2007,7,7]],"date-time":"2007-07-07T11:23:19Z","timestamp":1183807399000},"page":"84-92","source":"Crossref","is-referenced-by-count":0,"title":["Real\u2010time range measurement device using slit\u2010ray projection"],"prefix":"10.1002","volume":"17","author":[{"given":"Shin","family":"Yamamoto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomoaki","family":"Nakano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Osamu","family":"Ozeki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,3,21]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/0146-664X(73)90024-5"},{"key":"e_1_2_1_3_2","first-page":"5","article-title":"Feature extraction of three\u2010dimensional object by laser tracker","volume":"10","author":"Ishii","year":"1974","journal-title":"Proc.
