ScanNet是一个RGB-D视频数据集,包含1500多个扫描中的250万个视图,用3D摄像机的姿势、表面重建和实例级的语义分割来注释。为了收集这些数据,我们设计了一个易于使用和可扩展的RGB-D捕捉系统,包括自动表面重建和众包语义注释。我们表明,使用这些数据有助于在几个三维场景理解任务上实现最先进的性能,包括三维物体分类、语义体素标签和CAD模型检索。
在ScanNet之后发布了ScanNet v2(全部文件很大, 共1.3T),好像现在大部分使用的都是v2版本,具体更改见:ScanNet Changelog,主要更改如下:
Changelo中ScanNet v2 (2018-06-11)
声明为:
ScanNet 的新 2D/3D 基准挑战(benchmark challenge)
新的语义标签和实例注释(semantic label and instance annotations )
新的场景类型注释
新的轴对齐
一般从别的博客直接copy下来的代码好像不能进行下载,所以需要自己申请一下。

脚本:https://github.com/ScanNet/ScanNet/tree/master/SensReader/python
脚本说明是使用python 2.7
开发和测试。
脚本使用的参考命令:
python reader.py --filename [.sens file to export data from] --output_path [output directory to export data to]
Options:
--export_depth_images: export all depth frames as 16-bit pngs (depth shift 1000)
--export_color_images: export all color frames as 8-bit rgb jpgs
--export_poses: export all camera poses (4x4 matrix, camera to world)
--export_intrinsics: export camera intrinsics (4x4 matrix)
以scene0004_00为例
将脚本reader.py
,SensorData.py
copy进数据序列文件夹(下图中SensorData.pyc
是后来生成的)
python reader.py --filename scene0004_00.sens --output_path . --export_depth_images --export_color_images --export_poses --export_intrinsics
将结果存储在四个文件夹中
确实是深度图像,虽然下面截图看不清:
imageio requires Python '>=3.5' but the running Python is 2.7.17
参考:(https://blog.csdn.net/space_dandy/article/details/108142800)得知最新版本的imageio仅支持python>=3.5的版本,可以选择小于小于2.6.1版本的imageio库,结合(https://stackoverflow.com/questions/57332153/pytest-requires-python-3-5-but-the-running-python-is-2-7-10)关于pytest
类似的包的相似处理办法
解决办法为:
pip install "imageio<2.6.1"
ImportError: No module named png
参考:https://github.com/liuwons/wxBot/issues/79
pip install pypng
持续报错:
IOError: [Errno 2] No such file or directory: '/tmp/pip-build-xPQDii/pypng/setup.py'
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-xPQDii/pypng/
参考下面(3)使用python3.8(anaconda创建环境) 中 报错2
安装的版本,这里降低版本
输入pip install "pypng<0.2.0"
scene0004_00
python reader.py --filename scene0004_00.sens --output_path . --export_depth_images --export_color_images --export_poses --export_intrinsics
print 'exporting', len(self.frames)//frame_skip, 'camera poses to', output_path
^
SyntaxError: invalid syntax
结合python2和python3的print()函数的不同,修改SensorData.py
的以下四处----给print()函数加()
# print 'exporting', len(self.frames)//frame_skip, ' depth frames to', output_path #hxz
print ('exporting', len(self.frames)//frame_skip, ' depth frames to', output_path) #hxz
# print 'exporting', len(self.frames)//frame_skip, 'color frames to', output_path #hxz
print ('exporting', len(self.frames)//frame_skip, 'color frames to', output_path) #hxz
# print 'exporting', len(self.frames)//frame_skip, 'camera poses to', output_path #hxz
print ('exporting', len(self.frames)//frame_skip, 'camera poses to', output_path) #hxz
# print 'exporting camera intrinsics to', output_path #hxz
print ('exporting camera intrinsics to', output_path) #hxz
