Measuring apparent length of object (in pixels) using OpenCV

由 纵然是瞬间 提交于 2021-01-07 00:04:47
问题 I have used blender to render different images of my 3D object from different angles/poses. The object has colored edges (as shown in the image). Now, I aim to measure the length of the orange and blue edge ( Lo and Lb ) in pixels, using OpenCV. Had the edge been made of a single pixel (i.e., a line made of a single edge), it would be an easy task. But, this is not the case here. Any help is appreciated. 回答1: Here is one way in Python OpenCV. - Read the input - Threshold on one of the colors

How to import an fbx in Unity correctly?

问题 I've modelled an object and exported as fbx. After I import the asset in Unity, some artefacts show up. The artefacts seem to be related to Unity import and not do the fbx file as the model viewed in Windo3d 3d viever seem to have no issues. Thank you a lot!

The order of the vertices in a triangle, when combined with their visual orientation, can be

Golem 项目白皮书

由 Deadly 提交于 2021-01-03 16:46:20
Golem项目概览宏大愿景和核心特征 Golem是第一个真正去中心的全球算力市场。Golem结合灵活的开发工具,帮助开发者 发布软件并赚钱,进而改变了算力任务的组织和执行方式。通过实现去中心微服务和 异步任务执行,Golem致力于成为建设未来互联网的基石。通过大幅降低计算价格,复 杂的应用,如CGI渲染,科学计算,机器学习(人工智能)将惠及每个人。 通过P2P网络连接电脑,使应用所有者和个体用户(算力“请求方”)可以从其他用户租 用算力(算力“供应商”)。这些算力资源可以完成对计算时间和计算能力有一定要求 的计算任务。在当下,算力资源被中心化云服务商把控,受制于封闭网络,外部支付 系统,和死板的运营模式。Golem还有一个核心内置的特性—基于以太的支付转账系 统,可以实现算力买家(请求方),卖家(供应商),及软件开发者之间的直接支付。 Golem作为去中心算力市场的支柱功能可以看作为是一种基建即服务(Iaas),也是一 种平台即服务(PaaS)。通过集成一些专属软件后,Golem会展现其真正的潜力。任何 有兴趣的第三方可以在Golem基础上自行创建和部署软件并通过应用注册市场进行发 布。在转账支付框架下,开发者可扩展和自定义支付方式,实现独特的赚钱方式。 Golem生态系统 Golem的商业应用可以归结为这样的现实,因为近年来的科技进步,算力资源市场可以根据全 新理论重新架构

短视频特效“耍花招”：线上投篮、摆摊，让画中人摇摆，浅谈腾讯微视的AR基建...
