HJ Machine & Pattern (HJMP), located in Waterloo, Ontario, is the leading manufacturer of manufacturingjigs, die, patterns and tools. Since established in 1975, HJMP has supplied inspection and assembly fixtures toTier 1 & 2 automotive organizations who supply the final product to all major car manufacturers.In automobiles, many types of curved tubes are used, such as power steering lines, fuel rails, thin brakelines to large exhaust pipe. It is essential to inspect them correctly by measuring the tube shapes anddimensions for the production of correct parts and prevention of the scrapping of good parts. Traditionally,these measurements were conducted with the help of inspection fixtures; however, the measuring resultsdepend very much on the operator. Also it can only decide 'pass or fail', and cannot derive the information onthe overall dimensions and tolerances (bend data). HJMP plans to develop a new inspection system that can notonly make the pass/fail decision but also derive the 3D bend data accurately with minimumoperator-dependence, through the collaboration with University of Waterloo.Therefore, main objective of the project is to develop an optical tube measurement system that canaccurately measure the 3D geometry of curved tubes and derive the measurement report. It will be pursued byinvestigating two stage of solutions: The first stage is to integrate the optical technology with conventionalinspection fixture, mainly to make pass/fail decision accurately with minimal operator dependence. The secondstage is to develop an optical system that will capture the images of the tube with several high-resolution digitalcameras and convert the image data to key dimensions of the tube.The proposed optical measurement system will equip HJMP with new type of inspection technology, andprovide an opportunity to develop a new market. Upon completion, HJMP would be equipped with enhancedcompetitiveness and productivity to excel in the competitive market with its improved technology, pricing anda new solution, thus contributing to Canadian economy, by adding jobs and expanding exports.

位于加拿大安大略滑铁卢市的宏杰机械模具有限公司是一家专业生产模具、夹具、模具和工具的公司。自1975年成立以来，HJMP一直为Tier 1和Tier 2汽车组织提供检测和装配夹具，这些组织为所有主要汽车制造商提供最终产品。在汽车中，许多类型的弯管被使用，例如动力转向管路，燃油导轨，薄制动管路到大型排气管。必须通过测量管的形状和尺寸来正确地检查它们，以生产正确的零件并防止报废良好的零件。传统上，这些测量是在检查夹具的帮助下进行的;然而，测量结果在很大程度上取决于操作员。此外，它只能决定“通过或失败”，而不能获得关于总体尺寸和公差的信息（弯曲数据）。HJMP计划通过与滑铁卢大学的合作，开发一种新的检测系统，该系统不仅可以做出合格/不合格的决定，还可以以最小的操作员依赖性精确地导出3D弯曲数据。因此，该项目的主要目标是开发一种光学管测量系统，该系统可以精确地测量弯曲管的3D几何形状并导出测量报告。它将通过调查两个阶段的解决方案来追求：第一阶段是将光学技术与传统的检测夹具相结合，主要是以最小的操作员依赖性准确地做出通过/失败的决定。第二阶段是开发一个光学系统，该系统将使用多个高分辨率数码相机捕获管子的图像，并将图像数据转换为管子的关键尺寸。拟议的光学测量系统将为HJMP提供新型的检测技术，并提供开拓新市场的机会。完成后，HJMP将具备更强的竞争力和生产力，以其改进的技术，价格和新的解决方案在竞争激烈的市场中脱颖而出，从而通过增加就业机会和扩大出口为加拿大经济做出贡献。
