Abstract
Description
ズームモータが作動すると、このファンにより起こされるカメラ内の空気の流れは、空気誘導部材によりカバーガラスの後面に導かれる。」と記載されている。
本発明の車載画像処理装置の実施形態について説明する。図1は、本発明の車載画像処理装置が有する放熱構造の一例を示す図である。
車載画像処理装置であるステレオカメラは、左右一対のレンズ13と、該レンズ13を通過した光が結像する撮像素子と、該撮像素子によって撮影された画像を処理する基板(処理回路基板)17と、基板17を保持する筐体12を備えている。ステレオカメラは、一方の端にレンズ13と撮像素子からなるカメラ部を持ち、そのカメラ部をもう一方の端にも持つ。二つのカメラ部を筐体12によって接続し、一定の基線長でレンズの位置を保つ。また、カメラの撮像範囲にかからないように配置された壁14を両カメラに持つ。この該壁14については、カメラの形状により、必ずしも設ける必要はない。
基板17は、筐体12へ固定されている。
演算用のIC16は、前述のように基板17に実装されるが、その際、車両取付姿勢のカメラにおいて、上方へ熱を伝導させる構造とする。筐体12の放熱構造11は、基板17のIC16に対応する位置に形成されている。IC16は、基板17の中で発熱量が多く、筐体12に熱伝達することによって、筐体12の放熱構造11から効果的に放熱することができる。IC16から筐体12への熱伝達は、放熱伝導材18を介して行われる。放熱伝導材18は例えばシート状のものや、ペースト状のものである。
更に複数の放熱構造11は、ステレオカメラの長手方向の中央部に対してできるだけ対称の位置に設けるのが好ましい。これにより、左右のカメラ部は、IC16からの温度により筐体12が変形する際、左右対称の変形をすることになり、ステレオカメラとしての性能低下を抑制することができる。
図3A~図3Dを用いて、レンズ13への空気流量を増やすための構造について説明する。
放熱構造11を構成する複数の放熱体等の形状は、図3Aのように、流路入口31から流路出口32に向かって一直線状に延びる直線構造でもよいし、図3Bのように、放熱面間の距離が途中で段階的に小さくなる非直線構造でもよい。
図4を用いて、放熱構造11の別の設置例について説明する。
図5を用いて、放熱構造の別の構成例について説明する。
