Monitoring system and image reconstruction method for planting bed
An image reconstruction method adapted to use with a planting bed is provided. The planting bed is constituted by a work platform disposed on a work plane and for supporting a plurality of plants thereon. The image reconstruction method includes steps of: capturing a plurality of images of the work platform from different positions on a monitoring plane to obtain a plurality of image data, wherein the monitoring plane is opposite to the work plane, the monitoring and work planes are parallel to each other in a visible range and have a predetermined distance therebetween; and performing an image stitching algorithm to stitch the image data into a two-dimensional image of the planting bed. A monitoring system of a planting bed is also provided.
1. A monitoring system adapted to use with a planting bed, the planting bed being constituted by a work platform disposed on a work plane and for supporting a plurality of plants thereon, the monitoring system comprising:
a supporting bracket disposed on the working platform for defining a monitoring plane opposite to the work plane, wherein the monitoring and work planes are parallel to each other in a visible range and have a predetermined distance therebetween;
a sliding module supported by the supporting bracket and comprising a sliding structure capable of sliding on the monitoring plane in a predetermined direction;
an image capture apparatus installed to the sliding structure for capturing a plurality of images of the work platform from different positions on the monitoring plane and thereby obtaining a plurality of image data while the sliding structure is driven to slide in the predetermined direction; and
an analysis unit signal connected to the image capture apparatus;
wherein the analysis unit is configured to perform an image stitching algorithm to stitch the image data into a two-dimensional image of the planting bed, the analysis unit is further configured to obtain a plurality of height data of the different positions on the work platform according to parallaxes between the images of the work platform captured from different positions on the monitoring plane and perform a stereo vision algorithm on the two-dimensional image of the planting bed and the height data to obtain a three-dimensional image of the planting bed.
2. The monitoring system according to claim 1 , wherein the image capture apparatus is either a still image camera or a video recorder.
3. The monitoring system according to claim 1 , wherein the analysis unit is a desktop computer or a portable computer.
4. The monitoring system according to claim 1 , wherein the analysis unit is a smart handheld device.
5. The monitoring system according to claim 1 , wherein the analysis unit is a software product.
