In order to determine the optimum scale and band of forest aerial photography, determine-the enlargement of photo, interpretation in the experimental sites of Nankunshan, Guangong province carried out the following tests, namely determination of the spectrum of ground objects, multiple spectrum and colour infrared photograph in different scales, office interpretation, field survey and complex analyse. This article discussed the influence of aerial camera, film, coefficient of reflection of object spectrum and photographic displacement on resolving power. It also estimated the resolving power of photo image in Nanjunshan with the experimental relationship-formula and illustrated the interpretation in room and field survey. The breif conclusions are as follow: 400-800um in green band is the best for aerial forest photograph. The resolution of photo for forest interpretation is enlarged to 3.5 line/mm. If new type camera and film with high resolving power are used, photo-scale for classfication of forest resource will be decreased to 1:48000.

为了确定森林航空摄影的最佳比例尺和波段以及判读像片的放大倍数,我们在广东省南昆山林业遥感试验场,测定了地物光谱,拍摄了不同比例尺的多光谱片和彩色红外片,进行了内业判读、野外检测和综合分析。本文讨论了航空摄影机、胶片、地物光谱反射系数和摄影位移等因素对像片分辨力的影响,用经验关系式估算了南昆山像片的影像分辨力,阐述了内业判读和实地检测的情况。试验表明,在所试验的波长附围内绿波段表达森林影像的效果最佳,用于森林判读的影像分辨力宜放大到3.5线/毫米,若用新型航空摄影机和高分辨力胶片,则用于森林资源调查分类判读的像片比例尺可缩小到1:4.8万。

Prior to theresearch project, the multi-spectral photographic cameras used in the world have a small format (mostly 6cm ×6cm, so it is called 6MSP), the 6 MSP could not be used for mapping; the "harmful absorption" of spectral photometry is great so that the image quality is not up to standard; Due to the small format, the processing work is great during flying and later period. This project uses aerial photogrammetric cameras of format 18cm × 18cm and 23 ×23cm which composed multi-spectral camera groups, and...

Prior to theresearch project, the multi-spectral photographic cameras used in the world have a small format (mostly 6cm ×6cm, so it is called 6MSP), the 6 MSP could not be used for mapping; the "harmful absorption" of spectral photometry is great so that the image quality is not up to standard; Due to the small format, the processing work is great during flying and later period. This project uses aerial photogrammetric cameras of format 18cm × 18cm and 23 ×23cm which composed multi-spectral camera groups, and the spectral photometry which has no "harmful absorption" is constituted by "cut-off filter and special sensitive film" that enables the format of the multi-spectral aerial photography to increase by 9 times and 14.7 times more than 6MSP, and it allows"one photography-multiple usage", e.g the photographs can be used for mapping and for resources investigation and environment monitoring. As there is no "harmful absorption" so the quality of multi-spectral image is higher, and can be used for visual interpretation and also can be input into compcter in order to do the objects classification and interpretation accurately. 18-23MSP is an efficient aerial remote sensing techniques.

此项研究是国家科技攻关项目。在研究此课题以前,世界上采用的多光谱航空摄影机一直是小像幅的(大部分为6cmx6cm,代称为6MSP)。6MSP不能测图,分光“有害吸收”大,故图像质量差,且像幅小,飞行和后期加工量极大。本研究采用18cm×l8cm和23cm×23cm像幅航空摄影测量像机组成多光谱像机组,并设计了“截止滤光镜一特制感光胶片”组合的无“有害吸收”的分光系统,使本多光谱航空摄影像幅比6MSP加大了9倍和14.7倍,并能“一摄多用”,既能测图,又能进行资源调查和环境监测,其图像因无“有害吸收”,分光质量高,可供目视判读,也可输入计算机进行准确地物分类解译。18-23MSP是一项有效的航空遥感技术。
