Depending on the functional form, we need to keep some coefficients, which will be discussed in this ticket as well as other required columns.</p> INSTRM-1240

Add a table for the cordinate transformation between MCS and PFI

Task Normal Done Done Kiyoto Yabe Kiyoto Yabe opDB Thu, 15 Apr 2021 02:37:51 +0000 Fri, 14 May 2021 06:57:08 +0000 Fri, 14 May 2021 06:57:08 +0000 spt_operational_database 0 2 <p>My initial proposal is to add `mcs_pfi_transformation` table linking with `mcs_exposure.mcs_frame_id`. I'm not sure what coefficients we need, so they are completely placeholders. Any comments are welcome. &gt; <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=chyan" class="user-hover" rel="chyan">chyan</a> <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=karr" class="user-hover" rel="karr">karr</a> <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=cloomis" class="user-hover" rel="cloomis">cloomis</a> <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=hassan" class="user-hover" rel="hassan">hassan</a></p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> <span class="code-keyword">class </span>mcs_pfi_transformation(Base): ''' The MCS-PFI coordinate transformation including coefficients ''' __tablename__ = <span class="code-quote">'mcs_pfi_transformation'</span> mcs_frame_id = Column(<span class="code-object">Integer</span>, ForeignKey(<span class="code-quote">'mcs_exposure.mcs_frame_id'</span>), primary_key=True, unique=True, autoincrement=False, comment=<span class="code-quote">'MCS frame identifier as generated from Gen2'</span>) c0 = Column(REAL, comment=<span class="code-quote">'coefficient 0'</span>) c1 = Column(REAL, comment=<span class="code-quote">'coefficient 1'</span>) c2 = Column(REAL, comment=<span class="code-quote">'coefficient 2'</span>) def __init__(self, mcs_frame_id, c0, c1, c2 ): self.mcs_frame_id = mcs_frame_id self.c0 = c0 self.c1 = c1 self.c2 = c2 </pre> </div></div> <p>So if we were to do an affine transformation between the two coordinate systems, you would store the full 9 coefficients for the 3x3 matrix this way, correct?</p> Development Rank 0|zzs4z4:
