Description

請求項１に記載の車載ステレオカメラは、第１光学部材を介して被写体像を撮像する第１撮像部が取り付けされた第１撮像筐体と、第２光学部材を介して被写体像を撮像する第２撮像部が取り付けられた第２撮像筐体と、第１撮像部と第２撮像部から出力された信号を処理するための回路が設けられた基板と、長手方向に延在するステーとを備え、第１撮像筐体は、ステーの長手方向の一方の端部に固定され、第２撮像筐体は、ステーの長手方向の他方の端部に固定され、基板は、ステーの長手方向に沿って複数に分割された部分基板から構成され、部分基板のそれぞれは、ステーに対して長手方向へ自由度を有して固定するための第１孔と、ステーに対して長手方向への自由度を有することなく固定するための第２孔とを備えることを特徴とする。 The in-vehicle stereo camera according to claim 1 captures a subject image via a first imaging housing to which a first imaging unit that captures a subject image via a first optical member is attached, and a second optical member. A second imaging housing to which the second imaging unit is attached; a substrate on which a circuit for processing signals output from the first imaging unit and the second imaging unit is provided; and a stay extending in the longitudinal direction; comprising a first image pickup housing is fixed to one end portion in the longitudinal direction of the stay, the second imaging housing is fixed to the other end portion in the longitudinal direction of the stay, the substrate in the longitudinal direction of the stay Each of the partial substrates is divided into a plurality of partial substrates, and each of the partial substrates has a first hole for fixing with a degree of freedom in the longitudinal direction with respect to the stay, and a longitudinal direction with respect to the stay. And a second hole for fixing without having a degree of freedom. To.
