著者が先に発表した空中写真のステレオマッチングの手続きである多段階相関法には、隠蔽部分に対する考慮がされていなかった。この論文は隠蔽部分を含む画像にも適するように手法の改良を試みたものである。主要な論点は次の様である。(1) 隠蔽部分ではマッチングの迷走が生じる。これまでは計測したx―視差の微小振動を除去するために低域通過フィルタをほどこしていたが, これによると隠蔽部分では地形が強制的になめらかに再現されてしまう。(2) 低域通過フィルタのかわりにメディアンフィルタを用い, かつ段階的に隠蔽部分を見出していく手続きを提案し, それが基本的には有効に働くことを実験で示した。(3) この手続きによっても隠蔽部分とその周辺でマッチングの迷走が発生することがあるが, 正確なマッチングを防げる主たる要因はマッチングの収束の安定性が不足していることであることが明らかになった。

Many studies about the geometrical problem for single aircraft MSS data coverage have been made, and the effective orientation and restitution methods have been already developed by G. Konecny, et al.. Little, however, has been done in Japan in the way of investigating this problem fundamentally and clarifying difficulties in the practical analysis of MSS data. Therefore, in this report, the orientation problem for single aircraft MSS data coverage is analyzed on the Konecnys theory and then the restitution problem is treated. The authors introduced a simple restitution technique which was applicable to MSS data of hilly terrain.The method introduced was tested with an experimental model (MSS imagery of Kyoto City) in order to investigate the accuracies attainable. In this paper, some of the findings are reported in the practical restitution of aircraft MSS data.

In order to recognize the parrerns represented in a map, picking out of distribution patterens in the map has to be done as pre-processing. Quantitization method was used to pick up the distribution patterns and B. G. R. and B. W. methods are applied for quantitization. Picking out of colour tone distributions was carried out by applying this method. The results show that the accuracy of this method is farily good. But we, also, find some misrecognitions and luck of similitude of patterns between original and obtained figures. In this paper, so, improvement of accuracy are attempted by changing the scale of colour slide obtained from the original map and by increasing nomber of sampling points. As another processing technique, continuous tone negative film separeted each colour tone in the original map is investigated.As these results, it is clear that distribution patterns represented by several colour tones are able to pick up fairly well by B. G. R. and B. W. method, and they will also be picked out simply by using B. G. R. method only.
