Product Description
4G/WIFI Wireless Time-lapse Camera
1. Product Overview
4G version time-lapse camera
DAQ-GP-CAM is a wireless time-lapse camera based on 4G or WiFi, which can take pictures at certain intervals and upload to FTP server, launched by Shanghai Data Acquisition IOT Technology Co., Ltd. It can be widely used to capture the data of instruments, and can also be used for photo capture and video surveillance in the fields of cultural relics, rock and soil, hydrology and water conservancy.
This product supports WiFi/4G Ethernet access to the network, take photos regularly and upload the photos to the designated FTP server or store them in an SD card. With 4G wireless network card, it can be used in scenarios where there is no WiFi network outdoors.

8 Custom Development of Dashboard Recognition Software
8.1 Introduction to Pointer Meter Recognition/OCR Algorithms
Gaussian Filtering is generally used for image noise reduction. Canny Edge Detection method is generally used for edge detection of preprocessed images. Find the profile of the meter and panel by accurately filtering various non-critical targets. The instrument scale and instrument pointer can be detected by Hough transform, and the liquid level can also be detected by Hough transform. For the targets that need to do image classification, deep learning methods are adopted, such as number recognition, instrument style recognition and text position detection in natural scenes. The model adopts the convolutional neural network (CNN) model of deep learning, and builds different network models according to the features of the images.
Pointer type instrument recognition is mainly for pointer type instrument, which is a function of automatic recognition of industrial instrument recognition through video images.
The identification process is: using some special methods to complete the effective area screening and the pointer positioning of the instrument, according to the dial center to the dial center of the line and the Angle of the sub-dial 0 scale line, calculate the Angle between the sub-dial 0 scale line and the pointer pointing line segment, and further identify and interpret the pointer reading. The experimental results show that the algorithm is simple and accurate, and overcomes the influence of the dial's random Angle tilt on the reading recognition algorithm.
