However, some of the pores may be clogged by the printing material powder during the printing process. Such defects negatively affect the quality of the pulp packages produced using the mesh screen mold. To pinpoint the defects, we design a model-based robotic visual sensing system, called RoboCam, which uses a robotic arm to carry a high-resolution camera for full inspection of a mold consisting of joined mesh screens. To inspect the entire mold, RoboCam plans the camera poses to capture multiple images of the mold and render synthesized images as references for identifying the clogged pores. In particular, we propose novel designs to rectify the inherent run-time pose errors of the robotic system for ensuring the reference quality and to accelerate the reference rendering for reducing inspection latency. Extensive evaluation shows that RoboCam\u2019s design outperforms various baselines, including three existing computer vision and convolution neural network-based inspection systems. RoboCam achieves a recall rate of 94.95% within 528 seconds latency for inspecting an entire mold with 13,000 designed pores.<\/jats:p>","DOI":"10.1145\/3715913","type":"journal-article","created":{"date-parts":[[2025,1,31]],"date-time":"2025-01-31T11:07:12Z","timestamp":1738321632000},"page":"1-23","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":1,"title":["RoboCam: Model-Based Robotic Visual Sensing for Precise Inspection of Mesh Screens"],"prefix":"10.1145","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-2934-3464","authenticated-orcid":false,"given":"Siyuan","family":"Zhou","sequence":"first","affiliation":[{"name":"HP-NTU Digital Manufacturing Corporate Lab, Nanyang Technological University, Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0115-8726","authenticated-orcid":false,"given":"Duc Van","family":"Le","sequence":"additional","affiliation":[{"name":"HP-NTU Digital Manufacturing Corporate Lab, Nanyang Technological University, Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8501-9488","authenticated-orcid":false,"given":"Linshan","family":"Jiang","sequence":"additional","affiliation":[{"name":"HP-NTU Digital Manufacturing Corporate Lab, Nanyang Technological University, Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-0718-8006","authenticated-orcid":false,"given":"Zhuoran","family":"Chen","sequence":"additional","affiliation":[{"name":"HP-NTU Digital Manufacturing Corporate Lab, Nanyang Technological University, Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1471-4154","authenticated-orcid":false,"given":"Xiaohua","family":"Peng","sequence":"additional","affiliation":[{"name":"HP-NTU Digital Manufacturing Corporate Lab, Nanyang Technological University, Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7306-2112","authenticated-orcid":false,"given":"Daren","family":"Ho","sequence":"additional","affiliation":[{"name":"HP Inc., Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5062-6226","authenticated-orcid":false,"given":"Jianmin","family":"Zheng","sequence":"additional","affiliation":[{"name":"College of Computing and Data Science, Nanyang Technological University, Singapore, Singapore"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8441-9973","authenticated-orcid":false,"given":"Rui","family":"Tan","sequence":"additional","affiliation":[{"name":"College of Computing and Data Science, Nanyang Technological University, Singapore, Singapore"}]}],"member":"320","published-online":{"date-parts":[[2025,3,23]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"crossref","unstructured":"Blender. 2024.
