根据侧视式孔内电视系统的特殊使用环境（圆孔和水）这一特点，标定了几个主要技术指标，如系统的垂直视场角、水平视场角，并给出了孔径与圆心角的关系曲线．这样在使用该电视系统进行孔内观测时，可以做出更确切的测井解释．进一步利用这些技术指标和曲线，能够直观而简便地测量和计算出裂缝及空洞等地质构造的精确尺寸，从而可使该电视系统从定性观察发展到定量测量的新阶段．
According to the characteristics of the special use environment (round hole and water) of side view type hole television system, several main technical indexes are calibrated, such as the vertical field of view and the horizontal field of view of the system, and the aperture and center Angular relationship curve. This allows for a more accurate log interpretation when using this television system for intra-bore observations. By further utilizing these technical indicators and curves, the precise size of geological structures such as cracks and voids can be measured and calculated intuitively and easily, so that the television system can be developed from qualitative observation to a new stage of quantitative measurement.
