To provide a distance calculation device and a vehicle control processing which, in calculating a distance between a vehicle and an object, enables a region ensuring excellent calculation accuracy to be enlarged, thereby improving practicality.SOLUTION: A distance calculation device 1 acquires an actual measurement distance Xs_o_n to an inside of an overlap region 7c using image data from left and right cameras 4a and 4b and calculates first and second estimation distances Xn_o_n and Xn_o_m to an inside of the overlap region 7c and an inside of a left nonoverlap region 7a, respectively, using the image data from the left camera 4a. In addition, the distance calculation device calculates such a correction value Kmod as decreases an absolute value of a difference E_id_n between the actual measurement distance Xs_o_n and the first estimation distance Xn_o_n when an object is in the overlap region 7c and calculates a calculation distance X_h by correcting an estimation distance Index_x_h with the correction value Kmod when the object is in the two regions 7a and 7c.SELECTED DRAWING: Figure 2
【課題】車両と対象物との距離を算出する場合において、良好な算出精度を確保できる領域を拡大することができ、実用性を向上させることができる距離算出装置及び車両制御処理を提供する。【解決手段】距離算出装置1は、左右のカメラ4a,4bからの画像データを用いて、重複領域7c内の実測距離Xs_o_nを取得し、左カメラ4aからの画像データを用いて、重複領域7c及び左非重複領域7a内の第1及び第2推定距離Xn_o_n,Xn_o_mを算出する。さらに、対象物が重複領域7c内にあるときに、実測距離Xs_o_nと第1推定距離Xn_o_との差分E_id_nの絶対値が減少するように、補正値Kmodを算出し、対象物が2つの領域7a,7c内にあるときの推定距離Index_x_hを補正値Kmodで補正することにより、算出距離X_hを算出する。【選択図】図2
