Accurate measurement of shape forms a vital part of the quality control process for manymanufacturing industries. The worldwide dimensional metrology equipment market is over $13bn and growing at 8% p.a. The traditional workhorse of the metrology lab, the Coordinate Measurement Machine, is accurate to 1 part in 100,000 or more, but is slow, expensive, and unsuitable for fragile samples. Optical alternatives developed in the last 15 years offer very high scan rates at reduced cost, but have three main drawbacks:1. Lateral resolution is typically 1 part in 1,000, limiting ability to measure geometricalfine detail;2. Accuracy is typically no more than 1 part in 20,000;3. ‘Un-cooperative’ surfaces (e.g. shiny metals, black carbon fibre composites) can bedifficult to measure.Phase Vision has developed successful white light scanners that overcome these challenges for objects of 0.5 – 2m size, and now wishes to develop a product family for samples in the more challenging 0.1 – 0.5 m size range that will - for the first time - bridge the performance gap between optical and mechanical scanners. The project will bring to market IP that has been validated and patented through previous feasibility studies. Objectives are:1. Develop a prototype for a new optical 3D sensor with up to 5x improvement in lateralresolution and a 5x improvement in measurement accuracy compared to the current state of the art;2. Implement novel algorithms incorporating the new hardware platform to allowmeasurement of both shiny and low reflectivity surfaces.The main benefit to Phase Vision will be new products that will address a broader market and thus allow faster market penetration. Benefits to the end users will include enhanced manufacturing efficiency; reduced time to market for new products; and increased efficiency or performance of products such as composite wings or jet engine turbine blades, all of which will translate to economic savings and reduced carbon footprints.

对于许多制造行业来说，准确测量形状构成了质量控制过程的重要组成部分。全球尺寸计量设备市场超过130亿美元，增长8％。计量实验室的传统主力坐标测量机是准确的100,000或更高的1个部分，但缓慢，昂贵，不适合脆弱的样品。过去15年中开发的光学替代方案以降低的成本提供了非常高的扫描率，但有三个主要缺点：1。横向分辨率通常为1,000中的1个部分，限制了测量几何细节细节的能力； 2。准确性通常不超过20,000; 3的零件。 “非合件”表面（例如闪亮的金属，黑色碳纤维组成）可以进行测量。相位视觉已经开发了成功的白光扫描仪，以克服0.5 - 2m尺寸的对象，现在希望在更挑战的0.1 - 0.5 m尺寸范围内开发一个挑战范围的产品家族的对象，以示例范围 - 毫无疑问 - 在第一次挑战范围内，毫无疑问地进行了表演。该项目将通过以前的可行性研究验证和专利的市场IP。目标是：1。与当前的ART状态相比，为新的光学3D传感器开发原型，横向分辨率提高了5倍，测量精度提高了5倍； 2。实施新型算法，增加了新的硬件平台，以允许闪闪发光和低反射率表面进行测量。相视觉的主要好处将是新产品，它将解决更广泛的市场，从而使市场渗透更快。最终用户的好处将包括提高的制造效率；减少了新产品市场的市场；并提高了诸如复合机翼或喷气发动机涡轮机叶片之类的产品的效率或性能，所有这些都将转化为经济节省和减少碳足迹。
