The core difference between side-view and forward-view endoscope camera modules lies in their imaging perspectives. The lens exit direction of the side-view module is perpendicular or nearly perpendicular to the main body of the module, enabling imaging of non-forward areas such as the sides and inner walls of the target object. It is particularly suitable for scenarios that require observing the side structures of narrow spaces, such as the side welding points in the narrow gaps of precision instruments and the corrosion on the inner walls of pipelines. In contrast, the lens exit direction of the forward-view module is consistent with the main body of the module, focusing on the target directly ahead. It is better at capturing details of the front area, such as directly viewing blockages inside pipelines and observing the surface state of components from the front. This difference in perspective directly determines the different spatial detection directions of the two.
In terms of the selection of applicable scenarios, side-view and forward-view endoscope camera modules each have their own focuses. With its unique perspective, the side-view module performs prominently in scenarios that require penetrating into narrow spaces and detecting side information. For example, in the detection of the connection of side circuits inside electronic devices and the observation of the side microstructures of narrow cavities in scientific research experiments, it can break through the limitations of forward observation and find problems hidden on the sides. The forward-view module is more suitable for detecting forward paths or forward targets, such as checking forward obstacles in pipelines and directly viewing the assembly status of components in precision instruments from the front. In scenarios that require a clear forward field of view, its imaging effect is more direct and efficient. The spatial structure of the scenario and detection needs are the key factors distinguishing the applications of the two.
In addition, there are certain connections and differences in the functional design of the two. The side-view module is usually combined with characteristics such as an ultra-small lens diameter to adapt to the side detection of narrow spaces, and the adjustment of its parameters such as focal length and viewing angle is more inclined to the clarity and breadth of side imaging. The forward-view module is optimized in terms of the focal length range and frame rate of forward imaging to ensure accurate and smooth capture of forward targets. However, both side-view and forward-view modules may adopt similar core technologies, such as high-quality image sensors and convenient interface designs, but they are targeted in terms of perspective-oriented functional adaptability, jointly meeting the endoscopic detection needs in different scenarios.
