Float32范围 python
Web为了与OpenEXR格式兼容,我们可以在0,1范围内将所有通道转换为float32。 注意: I认识到Open3D支持RGBD映像,但它似乎不支持将RGB和深度读写到单个文件。 下面的代码示例使用OpenCV而不是枕头。 我认为OpenCV支持EXR文件格式,但是我的OpenCV Python版本并不支持EXR。 WebJun 9, 2024 · It's not a dumb question at all, but the answer is complicated, and depends on how you're going to use the information. For example, the IEEE 754 binary64 type can faithfully represent any not-too-large not-too-small decimal value with 15 or fewer significant digits, but to represent a binary64 value faithfully in decimal requires 17 decimal digits. . …
