To realize the high-precision vision measurement for large scale machine parts, a new vision measurement method based on dimension characteristics of sequential partial images is proposed. To overcome the corresponding problems arising from the relative rotation between two sequential partial images, a rectifying method based on texture features is used at the first step. Then, the transitional distribution modality of part image edges and its effects on measurement precision are analyzed. To get rid of the effects, a method of edge-pixel compensation is put forward, which availably improve measurement precision. Finally, a case study is provided to demonstrate the analysis procedures and effectiveness of the proposed methodology. The experiments show that the relative error is less than 0.012% using the sequential image measurement method to gauge large scale straight-edge parts. The measurement precision meets the need of the precise measurement .","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121088166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is often used as a pre-processing step to gain a better understanding of the images and many techniques have been proposed to better register a set of images without user intervention. The performance of these techniques are often scene-dependent and a technique designed for one application often performs less favourably under a different condition. In this paper, the performance of a number of local descriptor methods which have been proposed for image registration are studied, in particular, the main focus is on the techniques based on the SIFT descriptor for use with Maori artefacts. These techniques have been previously studied and shown to have good performance in the case of planar scenes or scenes which are far away from the camera, however little data exist for geometrically-complex 3D scenes. The experimental setup used in the work which allows for a fair and accurate comparison of the techniques under a number of different conditions is presented. The results from the work are presented and the reasons for the poor performance of the descriptors under the given scenes and conditions are discussed. Finally, based on the results obtained, the proposed approach for automatic registration of images of Maori artefacts are presented.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131989275","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It has been a great achievement to deploy such machines in the operating theatre environment in close proximity to patients and operating staff, and now commercial systems are available. Tool point guidance and cutting through the control of tool-point/tissue interaction is essential to increase precision further, particularly when working with soft or flexible tissues. The ability to automatically retrieve information describing tissues and the state of the process remains a challenging aspect. This paper focuses on the developing field of controlling tool-point interaction with tissues. The potential to discriminate different conditions and the means to use this information for control offers great potential towards the future of autonomous systems in surgery. This offers the order of magnitude greater accuracy needed in micro-surgical processes. The paper explores the challenges and novelty in formulating actuation, sensory and control solutions through discussion of some examples.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122829017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The equipment can be by video camera recording, machine vision systems and force plates. Motion analysis systems supported by multi-camera machine vision systems are an expensive solution for many applications. Force plates are another measurement tool that can be used in conjunction with a machine vision system or as a separate system. In the case of the latter set-up, the force plate is able to measure the centroid and vector of the ground reaction force, and the data retrieved can be interpreted by clinical staff to determine the nature of balance or stance of a patient. There is valuable information in the transients that can be detected by this approach, however the force plate cannot be utilised to discriminate other spatial factors in the way that the loads are applied by the patient on the surface. This paper reports the distributive approach to tactile sensing applied to infer the 3 dimensional motion of a moving mass in a supporting mechanism placed on the 2 dimensional sensing surface. The distributive approach has the advantage over forceplates on constructional costs and the ability to discriminate many motion metrics of patients. Implementation of the system using only three low cost deflection sensing elements, positioned under the surface with the resulting signals interpreted by neural network implemented on a field programmable gate array (FPGA) output near real time sampling rates greater than 70 KHz. The investigation demonstrates that the performance is sufficiently accurate for the intended clinical application, having backing errors of less than 5% in all three dimensions.","PeriodicalId":421396,"journal":{"name":"2007 14th International Conference on Mechatronics and Machine Vision in Practice","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124124973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
